Studies on pest complex and seasonal incidence of major pests of Jasminum sambac cv. Mysuru Mallige

Abstract

Jasminum sambac cv. Mysuru Mallige, a Geographical Indication (GI) crop of the Mysuru region in Karnataka, has encountered challenges such as a restricted flowering period and escalating pest infestations, resulting in a decline in cultivation among farmers in and around Mysuru. Consequently, this study marks the inaugural comprehensive investigation into the pest complex and seasonal incidence of major pests affecting Jasminum sambac cv. Mysuru Mallige. Thirteen pests, including insects and mites, were documented, comprising four sucking insects, two defoliator pests, three borer pests, and a mite pest. Notably, the incidence of budworm (Hendecasis duplifascialis), bud and shoot worm (Elasmopalpus jasminophagus), shoot web worm (Margaronia unionalis), leaf web worm (Nausinoe geometralis), thrips (Thrips orientalis), and red spider mite (Tetranychus urticae) was relatively higher. Their incidence varied with crop stage and season, as detailed in this study.
