متن کاملToxicity of fatty acid salts to German and American cockroaches.
The toxicity of fatty acid salts to German, Blattella germanica (L.), and American cockroaches, Periplaneta americana (L.), was evaluated. Potassium and sodium laurate caused up to 95% mortality of German cockroaches and 100% mortality of American cockroaches. Even-numbered potassium fatty acid salts, C8-C18 were assessed for toxicity at 0.125, 0.25, 0.5, 1, and 2% concentrations by a 30-s imme...
متن کاملCytochrome P450 CYP6L1 is specifically expressed in the reproductive tissues of adult male German cockroaches, Blattella germanica (L.).
A full-length cDNA encoding a new cytochrome P450, CYP6L1, was cloned from German cockroaches, Blattella germanica. CYP6L1 has an open reading frame of 1509 nucleotides with a deduced protein of 503 amino acids and molecular mass of 57 Kd. CYP6L1 is most similar to CYP6H1, a putative ecdysone 20-hydroxylase from Locusta migratoria. CYP6L1 mRNA was not detected in embryos nor nymphs, nor in adul...
متن کاملAssessing the Susceptibility Status of Cypermethrin resistance in German Cockroaches (Blattella germanica: Blattellidae) to Hydramethylnon Gel Bait

متن کاملRepellency and Toxicity of Mint Oil to American and German Cockroaches (Dictyoptera: Blattidae and Blattellidae)
The repellency and toxicity of mint oil to American, Periplaneta americana (L.), and German, Blattella germanica (L.), cockroaches were evaluated in a series of laboratory experiments. In topical application experiments, mint oil was toxic to both species with toxicities (LD50s) of 2.57 (1.98– 4.20) in 10 l and 3.83 (2.35–7.34)% in 2 l for American and German cockroaches, respectively. In conti...
