Effects of Selected Insecticides and Nematicides on the In Vitro Development of the Entomogenous Nematode Neoaplectana carpocapsae.

摘要: The effects of organophosphates (mevinphos, phenamiphos, trichlorfon), carbamates (carbofuran, methomyl, oxamyl), a formamidine (chlordimeform), synthetic pyrethroid (fenvalerate), chlorinated hydrocarbon (methoxychlor). and an insect growth regulator (diflubenzuron) on in vitro development reproduction Neoaplectana carflocapsae were tested by incorporating each chemical into nematode rearing medium. Organophosphates adversely affected at concentrations = 0.1 mg/ml. Phenamiphos was the most toxic, with no 0.01 Inoculated infective juveniles developed to adults some carbamates, but limited or occurred. Chlordimeform inhibited 1.0 mg/ml, while diflubenzuron, fenvalerate, methoxychlor did not significantly (P 0.05) reduced organophosphate carbamate nematicides use for control plant-parasitic nematodes may be toxic N. carpocapsae soil. Key words: organophosphates, integrated pest management, biological control.
