1995Abstract Classically, cockroach baits are mixtures of insecticide in food or water that purportedly attract cockroaches and kill them after they eat or drink some of it. Presently the term “bait” is used to refer to a non-edible combination of insecticide and a food, odor or pheromone lure that kills the attracted insects if they contact

Modification of the properties of a translocation in the German cockroach by selection
Theoretical and Applied Genetics, 1984A stock of Blattella germanica bearing the interchange T(3; 12)/3;12 was subjected to close inbreeding with selection for random disjunction at metaphase I. After 3-4 generations of selection, interchange quadrivalent chiasma frequency decreased, variability in free bivalent chiasma frequency increased sharply, and individuals with either random or ...

Toxicity of fipronil to German and American cockroaches
Entomologia Experimentalis et Applicata, 1997AbstractTopical and oral toxicity of fipronil, compared to chlorpyrifos, was determined for the German cockroach, Blattella germanica (L.), and American cockroach, Periplaneta americana (L.). Fipronil and Combat bait matrices were evaluated for their attractancies to both species. In the topical toxicity tests, LD50's of fipronil, at 72 h after topical
