Detection of malathion and chlorpyrifos resistance mechanism in German cockroaches (Blattella germanica, Insecta: Blattodea: Blattellidae) using piperonyl butoxide and tributyl phosphorotrithioate
Introduction: German cockroach (Blattella germanica, Insecta: Blattodea: Blattellidae) is considered one of the most common household pests which can transfer pathogenic agents and also cause allergic reactions. Frequent and uncontrolled spraying caused resistance in German cockroach to insecticides. In this study we aimed, to determine the malathion and chlorpyrifos resistance mechanism ...
متن کاملInsecticide toxicity, synergism and resistance in the German cockroach (Dictyoptera: Blattellidae)
The toxicity of synergism of and resistance to insecticides in four strains of German cockroach, Blattella germanica (L.), were investigated. Toxicity of nine insecticides by topical application to the susceptible strain varied greater than 2,000-fold, with deltamethrin (LD50 = 0.004 micrograms per cockroach) and malathion (LD50 = 8.4 micrograms per cockroach) being the most and least toxic, re...
متن کاملStability, Cross-resistance and Effect of Synergists, PBO and DEF, on Deltamethrin Resistant Strain of Spodoptera exigua (Lepidoptera: Noctuidae) from Pakistan
Spodoptera exigua (Hubner), is a polyphagous pest of vegetables and field crops. A field population of S. exigua from Lodhran was found resistant to conventional insecticides. It gave 65, 66, 92, 73, 34 and 29–fold resistance to deltamethrin, cypermethrin, chlorpyrifos, profenofos, abamectin and spinosad respectively compared with Lab-PK susceptible population. Field population was divided into...
متن کاملInsecticide resistance and synergism in field collected German cockroaches (Dictyoptera: Blattellidae) in Peninsular Malaysia
Twelve strains of German cockroach, Blattella germanica (Linnaeus) were collected from various locations in Peninsular Malaysia and tested for their susceptibility to three groups of insecticides applied topically. The levels of resistance were low to high (2.8 to 92×) for carbamates (propoxur and bendiocarb), low (2.0 to 7.6×) for organophosphate (chlorpyrifos) and low to moderate (1.0 to 23×)...
