Abstract:

Investigation on incidence of insect pests on grain amaranth was undertaken at MRS, Hebbal, Bengaluru. During study period, 19 insect pests have been recorded throughout the cropping period. Among these, Stem weevil, leaf webber, leaf eating caterpillar and sucking pests are the major one. Five natural enemies were recorded during the present investigation. The natural enemies viz., predatory lady bird beetle, Cheilomenes sexmaculata, Cheilomenes vicina (Muls) and Propylea sp. (Coleoptera: Coccinellidae) were found to be feed on aphids, Black bug, Geocoris sp., Assassin bug, Irantha sp. were attacking on Spodoptera sp. and braconid parasitoid, Bracon sp. (Hymenotera :Braconidae) on leaf webber were recorded. Stem weevil population per plant was negatively correlated with maximum temperature and positively correlated with other weather parameters. Whereas Leaf webber and Coreid bug was positively correlated with maximum temperature (0.43) and negatively correlated with minimum temperature.
