摘要: The activity of tefluthrin, carbofuran, terbufos and dieldrin in soil against eggs different ages the southern corn rootworm, Diabrotica undecimpunctata howardi (Barber) (Coleoptera: Chrysomelidae) was determined. Embryological development following treatment with these insecticides also investigated to determine stage developmental arrest. Generally, younger were found be more susceptible, being least tefluthrin most potent ovicide combined egg age mortalities. Terbufos carbofuran relatively inactive older compared tefluthrin. stopped embryonic at time when acetylcholine esterase has been shown commence. Carbofuran, slowed but did not arrest development, although two former compounds prevented eclosion a greater degree than suggesting death during absorption serosal fluids eclosion. Neonate emergence resulted within few hours. results are discussed relation insecticidal action permeability changes membrane structure age. © 1997 SCI.
