Tests with Poison Baits against Cockroaches

Influence of sanitary conditions on the field performance of chlorpyrifos-based baits against American cockroaches, Periplaneta americana (L.) (Dictyoptera: Blattidae).

The role of sanitation in performance of insecticidal bait stations containing 0.5% chlorpyrifos against the American cockroach, Periplaneta americana (L.), was investigated in residential premises. Test sites were chosen from three locations in Penang Island, Malaysia, and clustered according to their sanitary conditions. Results indicated that at 1-week post-treatment, houses with good sanita...

Developmental Stage- and Gender-Dependent Differential Susceptibility of German Cockroaches (Dictyoptera: Blattellidae) to Various Commercial Baits

The toxicity of five commercial bait formulations (Raid Max, Combat, Maxforce, Avert PT310, and Magnetic Roach Food) against various stages and sexes of JWax-susceptible and Muncie-resistant strains of German cockroaches, Blatella germanica (L.), was investigated in choice and no-choice bioassays. The role of strain, bait, stage, sex, and feeding bioassay main effects on cockroach mortality was...

New Food Baits for Trapping German Cockroaches, Blattella germanica (L.) (Dictyoptera: Blattellidae).

German cockroaches (GCRs), Blattella germanica (L.) (Dictyoptera: Blattellidae), are attracted to those beer semiochemicals (e.g., ethanol) that formerly living and active yeasts have produced or otherwise formed in the brewing process. We predicted that an earlier step in the production of beer, where yeasts actively metabolize the sugar in malted barley powder (dry malt extract [DME]), is ver...

Inoculating Relevance Feedback Against Poison Pills

Field trial on the control effect of fipronil bait against German cockroaches.

A field trial on the control effect of fipronil poison bait against German cockroaches (Blatella germanica) was carried out at different restaurant types in Sinchon, Seoul, Republic of Korea. Monitoring was performed applying food baited traps for 2 days per week. Reduction rates of German cockroaches by applying fipronil baits were 90.9% at Korean restaurants, 96.4% at Chinese restaurants, and...
