各種殺虫剤のチュウトウゴキブリ (Blatta lateralis) に対する殺虫効力

抄録

The effects of six organophosphorus insecticides (Fenitrothion, Dichlorvos, Diazinon, Propetamphos, Chlorpyriphosmethyl, Fenthion), one carbamate insecticide (Propoxur), one chlorinated insecticide (γ-BHC) and one pyrethroid insecticide (Permethrin) to a colony of Blatta lateralis were investigated by the topical application method. Dichlorvos and Permethrin were most effective; Fenitrothion, Diazinon, Propetamphos and Chlorpyriphosmethyl were moderately effective, and Propoxur, Fenthion and γ-BHC were less effective. When compared with the LD-50 values per insect of other two species of cockroaches, B. lateralis was more susceptible than Periplaneta fuliginosa but less susceptible than Blattella germanica. Males were more susceptible than females in respective species. On the basis of the effectiveness of the same body weight, B. lateralis was most susceptible to all the tested insecticides. The females of B. lateralis and B. germanica were less susceptible than males, while the effects of P. fuliginosa varied with insecticides.
