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 and the accompanying manual is available for $36.

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).

  • Average number of progeny per ootheca: 14.

  • Developing nymphs pass through 9+ instars requiring 9 to 12 months.

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.
