Toxicological Effects of Selected Insecticides on Delphastus catalinae (Horn) (Coleoptera, Coccinellidae), a Predator of Bemisia tabaci Genn (Homoptera, Aleyrodidae)
Öz
Toxicological effects of selected insecticides, fenpropathrin+pyriproxifen, acetamiprid, diafenthiuron, pyriproxifen, and chlorfenapyr were tested by direct spray and dry film methods in the laboratory against adult and larvae (L3-L4) of Delphastus catalinae (Horn) (Col., Coccinellidae), a predator of whiteflies, including cotton whitefly, Bemisia tabaci (Genn.). Water was used as untreated control. Fenpropathrin+pyriproxifen, acetamiprid, and diafenthiuron were harmful to larvae and adults of D. catalinae in both methods. Pyriproxifen was to be seemed harmless to adults in direct spraying technique; however it was harmful to the adults in dry film method. Eggs laid by a few adults which developed pyriproxifen treated larvae failure to hatch in dry film method. In conclusion, chlorfenapyr was innocuous to larvae and adults of D. catalinae in both methods. Fenpropathrin+pyriproxifen, acetamiprid, diafenthiuron and pyriproxifen would be incompatible with biological control of whitefly by D. catalinae.
