Cockroach parasites
are available only when ordered as a program of weekly releases. Training materials are
available to help those in institutional pest control learn to implement biological
control of cockroaches. See workshop info below. The set of 4 VHS video
tapes of the workshop is available for $60 and the accompanying manual $10.

Cockroach Parasite and Host Descriptions
Aprostocetus hagenowii. A. hagenowii
attacks the egg capsule (ootheca) of eight species of peridomestic cockroaches. They
are Periplaneta americana (the American cockroach), P. fuliginosa (the
Smokybrown cockroach), P. australasiae (the Australian cockroach), P. brunnea (the
Brown cockroach), Blatta orientalis (the Oriental cockroach), Neostylopyga
rhombifolia (the Harlequin cockroach), Eurycotis floridana (the Florida
cockroach) and E. biolleyi. For more information on A. hagenowii, consult
the review article by LeBeck (1991).
A. hagenowii females lay their eggs
inside cockroach oothecae (egg case). The eggs batch and the developing larvae (of A.
hagenowii) consume the developing cockroach nymphs. The larvae continue to mature and
eventually pupate inside the cockroach oothecae. A. hagenowii reaches the
adult stage inside the cockroach ootheca. Adults emerge from the oothecae by chewing a
hole in the oothecal shell. Male and female A. hagenowii mate immediately upon
emerging from the cockroach ootheca. After mating, A. hagenowii females search for
more cockroach oothecae.
Biological information about Aprostocetus
hagenowii
Wasps mate immediately upon emerging.
Fertilized eggs produce female progeny, unfertilized eggs produce male progeny.
Female wasps live 7 to 10 days.
Females deposit eggs in hosts (oothecae) early in life (3 to 5 days of adult life).
Females attack 1 to 2 (occasionally 3)
hosts in their lifetime.
Developmental time: 32 to 40 days (egg
to adult). Dependent on temperature and number of individuals developing in host.
Average number of female progeny per
host: Dependent on host - American 45 to 55, Oriental- 60 to 70.
Sex ratio: 80% females.
NOTE: A. hagenowii will not
attack cockroach nymphs or adults. These stages need to be controlled by other methods
compatible with natural enemies (i.e., trapping or baits). A. hagenowii only
attacks cockroach oothecae.
Commonly
encountered hosts of Aprostocetus hagenowii
American cockroaches -
Periplaneta americana
Female cockroaches deposit oothecae
every 7 to 10 days. Adult females live between 1 and 3
years.
Cockroach nymphs emerge from oothecae
in 45 to 50 days (dependent on temperature).
Smokybrown cockroaches
- Periplaneta fuliginosa:
Female cockroaches deposit oothecae
every 10 to 14 days.
Adult females live between 1 and 1 1/2 years.
Cockroach nymphs emerge from oothecae
in 50 to 55 days (dependent on temperature).
Average number of progeny per ootheca:
20 to 22.
Developing nymphs pass through 9+
instars requiring 9 to 12 months.
Australian cockroaches
- Periplaneta australasiae:
Female cockroaches deposit oothecae
every 5 to 7 days.
Adult females live between 8 to 12
months.
Cockroach nymphs emerge from oothecae
in 60 to 65 days (dependent on temperature).
Average number of progeny per ootheca:
24.
Developing nymphs pass through 9+
instars requiring 5 to 7 months.
Oriental cockroaches -
Blafta orientalis:
Female cockroaches deposit
oothecae every 7 to 10 days.
Adult females live between 1 and
years.
Cockroach nymphs emerge from oothecae
in 55 to 60 days (dependent on temperature).
Average number of progeny per ootheca:
14.
- Developing nymphs pass through 9+
instars requiring 9 to 12 months.
Cockroach Parasites: Anastatus
tenuipes & Comperia merceti
Anastatus tenuipes & Comperia merceti attack the egg capsules (oothecae)
of only one peridomestic cockroach, the Brown banded cockroach (Supella longipalpa). Females
of A. tenuipes & C. merceti lay their eggs inside cockroach oothecae. The eggs
batch and the developing larvae (of A. hagenowii) consume the developing cockroach
nymphs. The larvae continue to mature and eventually pupate inside the cockroach oothecae.
A. tenuipes & C. merceti reach the adult stage inside the cockroach ootheca.
Adults emerge from the oothecae by chewing a hole in the oothecal shell. Male and female A.
hagenowii mate immediately upon emerging from the cockroach ootheca. After mating, A.
hagenowii females search for more cockroach oothecac. For more information on A.
tenuipes and/or C. merceti, consult the review article by LeBeck (1991).
Biological Information About the Parasites
Anastatus tenuipes:
Wasps mate immediately upon emerging.
Fertilized eggs produce female progeny, unfertilized eggs produce male progeny.
Female wasps live 4 to 6 days.
Females attack 1 to 2 hosts in their
lifetime.
Developmental time: 42 to 48 days (egg
to adult). Dependent on temperature and number of individuals developing in host.
Average number of female progeny per
host: 7.
Sex ratio: 86% females.
Comperia merceti:
Wasps mate immediately upon emerging.
Fertilized eggs produce female progeny, unfertilized eggs produce male progeny.
Female wasps live 3 to 5 days.
Females attack 1 to 2 hosts in their
lifetime.
Developmental time: 32 to 36 days (egg
to adult). Dependent on temperature and number of individuals developing in host.
Average number of female progeny per
host: 13.
Sex ratio: 82% females.
Note: No parasites
are currently available for German cockroaches. The egg case is tough and leathery and the female retains the case until the eggs hatch. She protects the case from parasites. If you know where we can find some, let us
know.
