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...
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.).

متن کاملLevel of CYP4G19 Expression Is Associated with Pyrethroid Resistance in Blattella germanica
German cockroaches have become a large problem in the Shenzhen area because of their pesticide resistance, especially to pyrethroid. A pyrethroid called "Jia Chong Qing" to prevent pests for a long time were found to be resistant to "Jia Chong Qing" with resistance index of 3.88 measured using RT-PCR and immunohistochemistry analysis showed that both CYP4G19 mRNA and CYP4G19 protein expression ...
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.
