Response of German cockroaches, Blattella germanica (Linnaeus) to baiting food on a sticky trap

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

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...

Assessing the Susceptibility Status of Cypermethrin resistance in German Cockroaches (Blattella germanica: Blattellidae) to Hydramethylnon Gel Bait

Background: The German cockroach (Blatella germanica) is one of the most important vectors of public health interest due to its involvement in the transmission of infectious diseases. Different insecticides are used to control cockroaches; however, resistance developed against most of insecticides has made them ineffective. Attempts should always be made to find proper alternat...

Reproductive effects of a neonicotinoid insecticide (Imidacloprid) in the German Cockroaches Blattella germanica L. (Dictyoptera, Blattellidae)

Imidacloprid a neonicotinoid insecticide was administrated by injection to newly emerged adults of the German cockroach Blattella germanica (Insecta, Dictyoptera) at 0.0002% and 0.0005% doses corresponding to the LD50 and LD90 respectively. The insecticidal effect of compound was investigated on ovarian growth during the first gonadotrophic cycle (0, 2, 4 and 6 days) under laboratory conditions...
