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

Semiochemical-based Food-foraging in German Cockroaches, Blattella Germanica L. (dictyoptera: Blattellidae)

Attractiveness of insecticide baits for cockroach control (Dictyoptera: Blattellidae): laboratory and field studies.

Several insecticide bait formulations were evaluated for their attractiveness to cockroaches in olfactometer assays in the laboratory and in trapping experiments in the field. Included in the assays were bait stations, gels, pastes, and a powder that contained one of the following active ingredients: abamectin, boric acid, chlorpyrifos, or hydramethylnon. There were significant differences amon...

Effect of Fipronil on Bait Formulation-Based Aversion in the German Cockroach (Dictyoptera: Blattellidae)

We examined the effects of 3 active ingredients in baits containing glucose on a behaviorally resistant (glucose-averse, T-164) strain of Blattella germanica L. Baits with glucose and hydramethylnon or chlorpyrifos killed few T-164 individuals; however, ÞpronilÐglucose baits killed 60% of the cockroaches by day 14. Although ingestion levels were low, ÞpronilÐglucose baits were consumed more tha...

Origin and extent of resistance to fipronil in the German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae).

Fipronil, a phenylpyrazole insecticide, was made available in 1999 in bait formulations for use against the German cockroach, Blattella germanica (L.). We have investigated resistance to fipronil in the descendants of cockroaches collected just before, or contemporaneously with, the introduction of fipronil baits. Cockroaches were obtained in two types of settings: homes that either had or had ...

The ABC’s of Indoor Health: Allergens, Baits, and Cockroach Mitigation Strategies

The German cockroach, Blattella germanica, is a major structural pest, and cockroach allergens have been linked to the development and exacerbation of allergic disease and asthma in cockroach sensitive individuals. The inner-city residential environment often supports large cockroach infestations, which expose residents to high levels of allergens. This review summarizes information on the publ...
