Abstract

The susceptibility of certain species of lepidopterous pupae occurring in different ecological situations to the entomogenous nematode, Neoaplectana carpocapsae, was tested. Soil- or litter-pupating lepidopterous insects were not highly susceptible to N. carpocapsae. The most susceptible insect pupating in the soil was Spodoptera cxigua with 63% pupal mortality, while Harrisinia brillians, which pupates in litter, had 55% mortality. Other soil- and litter-pupating insects had mortalities of less than 25%. Some insect species that pupate above ground were highly susceptible ( 84% mortality) to N. carpocapsae infection. Key words: biological control, nematode infection, pupal mortality.
