Significant Research Accomplishments

• Accomplishment: Dr. Vander Meer's collaborative efforts to develop delayed acting toxicants for fire ant control led to several pendant toxicant formulations (pro-toxicants) and most importantly, to the discovery of a powerful new class of delayed action toxicant. Dr. Vander Meer then led a concerted effort with the manufacturer, 3M Company, and colleagues to determine the compounds through structure-activity relationships. Patents have been issued on this class of compounds (perfluorinated sulfonamides and sulfonic acids). Role: Dr. Vander Meer was instrumental in guiding the efforts of the Southern Research Institute in developing controlled release toxicants for imported fire ant control under grants from ARS and APHIS. Dr. Vander Meer led collaborators in the discovery of unusual insecticidal activity and the structure/activity of surfactant controls. He then led efforts with colleagues to successfully patent a new class of insecticides and was the senior author on initial publications. Impact: The technology was transferred through issuance of an exclusive license to Griffin Corporation, Valdosta, GA, for development of the invention. EPA approval was obtained for the use of one of these compounds, "sulfluramid," against cockroaches and household ants. The product is currently available to the public in stores throughout the U.S., as a household Roach Bait station and an Ant Bait Station (Hot Shot®, MaxAttrax, Spectrum Group of Household Industries Corp.). The same company offers Spectricide's - Terminate - a Termite Killing System (sold in stores like Lowes and Home Depot). FMC Corporation has sub-licensed the invention and is producing FirstLine® Termite Defense System and other PCO products. The invention is used extensively in South America for leaf-cutting ant control. The licensing of this technology has successfully brought needed pest control products to the public. Based on royalties to the USDA, this invention ranks third in terms of monetary return to the ARS.
• Accomplishment: Dr. Vander Meer isolated, identified and synthesized four components from S. invicta's Dufour's gland that elicited trail orientation. Scientists had been working on this problem for over 20 years and its solution represented a major breakthrough in the study of fire ant pheromones. Further, the recruitment process was reduced to attraction, orientation induction, and orientation subcategories. Dr. Vander Meer's research efforts led to the development of new bioassays, the isolation and partial identification of the part of the recruitment pheromone used by foraging workers to attract other workers to a trail, and the discovery of a novel trail orientation inducer pheromone (it modulates and increases their sensitivity to the orientation pheromone). Role: Dr. Vander Meer conducted the research and directed the research of a Research Associate to achieve the accomplishments. Impact: The total fire ant recruitment pheromone (attraction, orientation induction, and orientation) as elucidated by Dr. Vander Meer and colleagues is the most completely understood ant pheromone system in terms of both chemistry and behavior, and serves as a model for researchers worldwide.
• Accomplishment: Discovered that each colony has a distinctive cuticular hydrocarbon pattern that dynamically changes with time. This and the discovery by a graduate student under Dr. Vander Meer's direction of an environmental contribution to the recognition cues helped elucidate the mechanism of cue/template matching, and the ontogeny of nestmate recognition. Recognition of intruders (other ants, pathogens, parasites, predators) as non-nestmate triggers colony defenses that protect the colony from invasion. However, some insects, myrmecophiles, and parasitic ant species have evolved mechanisms to get around these defenses and integrate into their host ant colonies. Two myrmecophiles, a beetle, Myrmecaphodius excavaticollis, and an Orasema sp. wasp were shown to acquire the colony's nestmate recognition cues. Determined in part the mechanism used by a parasitic ant to kill the existing queen and integrate into its host Formica ant colony. Role: Dr. Vander Meer led research efforts aimed at understanding nestmate recognition in fire ants and other ant species, as well as myrmecophile and parasite / host integration mechanisms through graduate students, postdocs, and collaborative interactions. Impact: Both the nestmate recognition and myrmecophile studies have had a major impact on hymenopteran nestmate recognition research and are frequently cited in nestmate recognition papers and reviews. "Cracking" the nestmate recognition code for the fire ant enabled us to better understand parasite, pathogen, and/or predator biological control agents, as well as biologically-based population suppression technologies. Investigations with a parasitic ant and its Formica host are leading the way to an understanding of parasitic ant/host integration mechanisms.
• Accomplishment: Dr. Vander Meer discovered, via chemical analyses, that the imported fire ants, S. richteri and S. invicta, hybridize. Morphologically the hybrid looks like its parent, S. richteri. Subsequent research using biochemical and genetic techniques demonstrated that the hybrid population is viable and extensive. Behavioral and additional chemical evidence for hybridization was obtained through a comparison of Dufour's gland Gas Chromatograph profiles and the behavioral responses of the parents and hybrid to the recruitment pheromone. The presence of natural hybrid populations was used to gain greater insight into fire ant nestmate recognition. In addition, Dr. Vander Meer developed methods to detect species-specific chemical characters (hydrocarbons and venom alkaloids) from a variety of sample types, including alcohol preserved specimens. This technique was used to analyze museum collections (1949, 1964) and to map the progression of the hybridization of the two imported species over time. These chemical characters are excellent taxonomic tools and represent the most reliable way to detect hybrid colonies. The same tools have been used to define the South American range of the two imported fire ants, also resulting in the discovery of what appear to be cryptic S. richteri species in South America. Role: Dr. Vander Meer made the initial discovery of hybridization then led the expansion of the discovery through collaborations and a Post Doc. In addition, the incumbent is leading the chemical identification of fire ant populations in South America that best match our imported populations in an effort to optimize biocontrol efforts. Impact: The discovery of hybridization raises many important questions regarding conventional and biological control strategies, as well as basic questions about hybrid vigor/cold-hardiness, speciation and the taxonomy of fire ants in South America. For biological control the chemical characters are being used to collect pathogens and parasites from areas in South America that most closely match our imported populations in order to bring back the most virulent form. Dr. Vander Meer currently collaborates with many groups in the U.S., including APHIS, to identify fire ant.
• Accomplishment: Dr. Vander Meer and coworkers made several discoveries relative to the multiplicity of functions centered on the fire ant's sting apparatus. For example, workers have a hierarchy of defensive behaviors that involve stinging, venom flinging, and aerosol dispersal. Broodtending workers aerosol minute amounts of the antimicrobial venom alkaloids onto brood and soil to promote colony hygiene. Demonstrated that the fire ant queen pheromone is stored in her venom sac and exits through the sting apparatus. This was the first report of the anatomical source of an ant queen pheromone. Discovered that the queen egg-laying mechanism involves sting extension followed by retraction across the eggs being laid. During this process poison gland products are deposited on the eggs. Since the queen is capable of depositing poison sac or Dufour's gland products on eggs, the discovery has many implications. Monogyne and polygyne S. invicta exhibit the same egg-laying behavior. Although individual polygyne queens have a lower oviposition rate than their monogyne counterparts, polygyne colonies produce significantly more eggs at the colony level. Role: Dr. Vander Meer directly participated in and led research with coworkers toward the noted accomplishments. Impact: Queen deposition of poison or Dufour's gland compounds is beneficial to the eggs and thus provides an evolutionary link between the ovipositor and accessory glands of solitary insects and the sting and the poison and Dufour's glands in aculeate Hymenoptera. The egg-laying behavior and deposition of queen-specific compounds on the eggs provide workers with a measure of their queen's fecundity and thus affects their behavior; queen egg-laying behavior and release of worker attractants facilitates the circulation of non-volatile queen primer pheromones into the colony. This work, coupled with Dr. Vander Meer's work on the recruitment pheromone and queen attractant pheromone, document the multifunctional role that the sting apparatus and its associated glands play in fire ant colony life.
• Accomplishment: Dr. Vander Meer determined 1. monogyne and polygyne fire ant workers respond equally well to queen-produced attractant pheromones. 2. significant attraction was obtained when the racemic queen pheromone (invictolide) was dissolved in the bait phagostimulant, soybean oil and absorbed in carrier grit particles. 3. fire ants discover pheromone enhanced baits significantly faster than non-enhanced baits, and in paired tests enhanced baits are discovered first up to 80% of the time. 4. invictolide enhanced bait kept in a closed vial, maintained structural integrity and biological activity for over two years-a necessary requirement for commercialization. 5. paired single mound treatments demonstrated that pheromone enhanced baits gave more rapid control than non-enhanced baits. 6. fire ants are not as efficient at discovering bait particles as previous dogma dictated. A Patent Application was submitted with our CRADA partner; however, invictolide was very expensive and American Cyanamid, Co. decided not to pursue commercialization - the Patent Application was abandoned. However, a new naturally occurring fire ant attractant was isolated and identified from unrefined soybean oil as isomers of 2,4-heptadienal. These compounds are not found in other oils. Demonstrated bait enhancement benefits for this commercially available compound and a patent has been issued. Initiated a CRADA with BioGuard R&D, Inc. to develop controlled release formulations of the heptadienal and/or invictolide. Role: Dr. Vander Meer was responsible for, participated in, and led research aimed at demonstrating the benefits of pheromone enhanced fire ant baits (funded in part through a CRADA with American Cyanamid, Co.). Dr. Vander Meer led the discovery, isolation, and identification of fire ant attractants from soybean oil. Impact: The queen pheromone, invictolide, was an excellent model to first demonstrate the concept and multiple benefits of pheromone enhanced baits (as outlined above). Discovery of attractants from soybean oil have opened up additional possibilities for bait enhanced - currently being explored through a CRADA with BioGuard, R&D, Inc. Successful development of enhanced bait will decrease the fire ant reinfestation rate by having less effect on non-target ant species, require less active ingredient and in another application provide a species-specific fire ant detection method.
• Accomplishment: Discovered and developed a number of effective fire ant repellents. A patent application was filed and four patents have been issued covering several classes of compounds described in the original application. Controlled release formulations of the volatile repellents was pursued through a Cooperative Research and Development Agreement with Hercon Environmental Co., who used a polymer laminate formulation to increase the active life of the repellents from minutes to several weeks. In a Cooperative Research and Development Agreement with Organic Plus, Inc. the repellents were absorbed onto diatomaceous earth, which effectively kept the ants from foraging on the surface for several hours. Recently, controlled release formulations were prepared by CRADA partner, BioGuard R&D, Inc. that effectively repelled fire ants for over two months. Role: Dr. Vander Meer led research with colleagues on fire ant repellents, then took charge of finding commercial partners to develop the invention. Impact: While these compounds do not kill fire ants, they do provide the opportunity to exclude ants from areas where they are not wanted without using insecticides. Potential applications include urban picnic areas, high human use places in parks and recreational areas, plant nurseries, hospitals, electrical equipment, interstate commerce, protection of endangered species, etc. A Phase I SBIR proposal was funded and successfully executed. An SBIR Phase II proposal has been funded to develop these repellents and a funded project was just completed with the Department of the Army at Ft. Hood, TX to use the controlled release repellents to protect an endangered bird species from fire ant predation. This work is continuing.
• Accomplishment: (A) Discovered that workers from polygyne fire ant populations lack agonistic behavior toward workers from polygyne or monogyne colonies. However, workers from monogyne colonies are aggressive toward all non-colony members. Thus polygyne populations behave as a single "supercolony". (B) Discovered that newly mated fire ant queens (NMQs) are normally executed by monogyne and polygyne workers; however, if either social form loses their queen(s), workers readily accept non-nestmate workers and NMQs. Polygyne colonies were created in the laboratory for the first time through adoption of NMQs by queenless worker groups. Monogyne field sites treated with toxic baits produced queenless worker groups and subsequently polygyne colonies. Discovered a relationship between biogenic amines/aggression levels/and queen presence or absence and proposed a new queen produced primer pheromone to explain results. Role: Dr. Vander Meer led research with colleagues aimed at discovering similarities or differences in nestmate recognition between monogyne and polygyne fire ant populations. Incumbent then led the discovery of NMQ adoption by queenless workers into novel areas that impact the spread of polygyny and the biochemical and physiological basis for the influence of the queen on nestmate recognition. Impact: (A) Polygyne populations behave as a uni- or supercolony, with free flow of worker, queen, and food from one colony to another. The simple aggression assay developed by the incumbent and co-workers reliably determines if a colony is polygyne or monogyne, this facilitated research into social form sympatric patterns in polygyne populations. Practically, a point source of bait toxicant rather than a broadcast treatment will work to control polygyne populations, since workers will distribute the bait population-wide. (B) Re-queening of queenless worker groups by NMQs has tremendous impact on how we view fire ant control and polygyny in the United States. At the least, adoption of NMQs will lead to rapid reinfestation of treated land. At the worst, chemical efforts to control S. invicta will promote the formation of polygyne populations. This work is at the cutting edge of nestmate recognition/primer pheromone research in ants and will become a model system for future social insect research in this area. National Research Initiative and Israel - United States Binational Science Foundation Grants were funded on this subject.
• Accomplishment: The sex pheromone of the moth, Utetheisa ornatrix was isolated, identified and synthesized. Several components from male moth coremata were isolated and identified, then demonstrated to be that enhanced successful mating. Role: Dr. Vander Meer isolated, identified and synthesized the sex attractant of the moth U. ornatrix; synthesized other pheromone isomers for biological testing and was actively involved with the cooperating biologists who discovered that pheromone emission occurs discontinuously, in the form of short pulses; isolated and identified aphrodisiac compounds from male moths. Impact: The sex pheromone structure was unique for Lepidoptera and the method of pheromone emission added another dimension to insect communication. This was the first time coremata components in moths have been shown to have behavioral effects. The incumbent's work along with that of his colleagues has been featured on public television nature programs and is now a classic, textbook chemical ecology story.
• Accomplishment: Dr. Vander Meer discovered relationships between (1) the area of a rhinoceros beetle's (Oryctes rhinoceros) elytra and its adult emergent weight, and (2) pupal weight and emergent weight. In addition, incumbent determined that rhinoceros beetles emerge from their pupal chambers, take their first flight, feed, and die at specific percent emergent weights. These physiological events are variable with time, but well defined by a percent emergent weight relationship. Dr. Vander Meer developed a unique olfactometer for Oryctes rhinoceros (L.) that was proven effective by a comparison of results with field-tested chemicals. Using the olfactometer, (-)-des-N-morphinan, but not its stereoisomer was found to be a strong attractant for adult rhinoceros beetles. Additional olfactometer work led to the discovery of structure-activity correlations for derivatives of siglure, an attractant for the rhinoceros beetle. Role: Dr. Vander Meer developed the olfactometer and discovered the fixed measurement - physiological state relationships. Collaborators provided chemicals for evaluation. Impact: The correlation work clearly differentiates between temporal and physiological time and allowed the adult emergent weight of trap-collected rhinoceros beetles to be determined simply by measuring the approximate elytra area. The ability to estimate the emergent weight of field beetles makes these correlations useful in control and ecological studies. This was the first synthetic bridged hydrocarbon found to be an insect attractant. The olfactometer made it possible to screen samples faster than by field testing and led to the discovery of better attractants, which were needed to bring beetles into traps that enabled inoculation with a viral biological control agent.
• Accomplishment: Incumbent led work that forced a reevaluation of the concept of anti-aphrodisiacs in Drosophila. Role: Dr. Vander Meer collaborated with other researchers, did the chemical analyses, and wrote the paper. Impact: The work revealed how hypotheses developed from extrapolation of results can be erroneously turned into fact through subsequent citations. In addition, this work led to a coauthored book chapter on Drosophila sexual behavior and ageing.
• Accomplishment: Dr. Vander Meer used caste-specific chemical markers and designed feeding experiments to establish that the first workers produced by a colony-founding queen represent a transient caste. Role: Dr. Vander Meer designed the experiments and led their execution. Impact: The results helps to explain the different behavior observed for minims and has broad implications on our view of colony development in fire ants and other social insects.
• Accomplishment: Many Pseudacteon flies are known to attack fire ants in South America. The flies are host specific and have been shown to stop fire ant foraging and may shift the local competitive balance to other ant species. Pseudacteon tricuspis was shown to be attracted to compounds released by electrically stimulated fire ants. In addition, the volatile compounds released by shaken fire ant workers attracted phorid fly parasites. Dr. Vander Meer subsequently demonstrated the involvement of alarm pheromones in the attraction of this phorid fly to their host fire ant. In the context of phorid fly rearing, electrical stimulation of ants resulted in about 30% more attacking flies, 15% fewer resting flies, and 20% increase in parasite pupae production. Role: Dr. Vander Meer spearheaded the electrical stimulation work, the subsequence determination of the attractant source, and pushed the development of electrical stimulation and phorid fly rearing. A colleague provided ready access to flies and advice on how to implement electrical stimulation in fly rearing. Impact: This work has enhanced the productivity of mass rearing efforts within ARS and APHIS. In addition, this work leads the way to development of phorid fly trap development for - detection of incipient fly populations, focus flies to a desired area, biotype selection in South America, collection of "wild" flies for rearing enhancement, research. This will become a major accomplishment after documentation in peer-reviewed journals.
