متن کاملSite of synthesis, tissue distribution, and lipophorin transport of hydrocarbons in Blattella germanica (L.) nymphs.
The site of hydrocarbon (HC) synthesis and the amount of HC in various tissues were investigated in relation to developmental stage in the last larval stadium of the German cockroach, Blattella germanica. Abdominal integument linearly incorporated [1-(14)C]propionate into HC for at least 6h in vitro, whereas other body parts synthesized little or no HC. The third through sixth abdominal sternit...
متن کاملOrigin 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 ...

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...
متن کاملConversion of ergosterol to 22-de-hydrocholesterol in Blattella germanica.
The literature suggests that several species of insects can convert Czs and Czs sterols to cholestane derivatives. According to Bergmann (l), cholesterol is the major sterol constituent (85%) and the plant sterol sitosterol a minor component of chrysalis oil obtained from the silkworm Bombyx mori, although this insect feeds exclusively on mulberry leaves. More recently, Bergmann and Levinson (2...
