The insect complex in the soyabean agro‐ecosystem at Khumaltar in Kathmandu Valley, Nepal

The population of insects on the soyabean crop was estimated from catches in a standard sweepnet from the upper canopy in the field two times a week beginning at the early vegetative stage up to maturity. The highest peaks of Abidama producta Walk and Cafna sp. were found in the beginning of stage V1; those of Sogatella furcifera Horvath, Adonia variagata, Afidenta mimetica simplex Oke, Coccinella septempunctata L., Haltica birmanensis Jac., Heterodeses lenis Cand., Ophionae indica Thnbg., Phillotreta sp., Piatypria histrix F., Popillia cupricolis Hope, Scatophaga stercoraria L., Meteorus nr. fragilis Wesm., Paedarus fuscipes Curtis at the vegetative stage (V2), and Nephotettix nigropictus Stall., Paratettix spp., Monolepta signata 01. and Monolepta spp. at stage V4. The populations of Aethus indicus West and of Cydmus aterrimus F. reached three peaks in (V1), (V4) and (V6) respectively. During the reproductive stages, Tipula melanomera Walk., Chauliops fallax Scott., Graptostethus servus Fab., L...
