abstract

  • Insect pests were collected from cultivated and wild plant species to study their parasites in Andhra Pradesh, India. Besides insects, nematodes emerged as parasites WhileHexamermis spp. were common in most lepidoptera,Ovomermis albicans (Siebold) was recovered fromHeliothis spp. The nematodes were active, even more than insect parasites during early monsoon. They were more active on light-soils than on heavy-soils. AgainstHeliothis armigera (Hubner) in particular, their incidence was more on ?low-growing? crops likeArachis hypogaea (L.), andLycopersicon esculentum (L.), and weeds. The nematode Pentatomimermis sp. was recorded from the bugNezara viridula L
