Insecticidal composition containing heterorhabditis nematodes and process

摘要

Disclosed is an insecticidal composition containing an effective amount of a juvenile infective-stage of an insecticidal entomopathogenic Heterorhabditis nematode transformed with hsp-70 gene and a biocompatible carrier therefor. The insecticidal composition containing the transformed Heterorhabditis nematode has improved insecticidal activity compared to a composition containing the corresponding nontransformed nematodes. Also disclosed is a process for reducing the population of soil-inhabiting insects in soil by applying to a soil locus infected with such insects the above-described insecticidal composition. Additionally, a process for improving the insecticidal activity of heterorhabditis nematode by transforming the nematode with hsp-70 gene is disclosed.
