Abstract
The present article provides a catalogue of tri-trophic associations of the common hover fly Ischiodon scutellaris (Fabricius) across India based on the published authentic literature. It is widely distributed in some parts of Europe, southeast Asia and Australia. It is the most effective natural enemy of aphid pests in economically important crops such as cereals, vegetables, oilseeds, cotton, pulses, etc. It is used in greenhouse aphid pest biocontrol programmes. Ischiodon scutellaris (Fabricius) was reported to prey on 50 species of aphids feeding on 88 species of plants excluding unidentified ones with 148 tri-trophic associations distributed in 21 states/union territories across India, mostly in Karnataka (36 triplets) followed by Uttar Pradesh (35 triplets), Uttarakhand (29 triplets), Manipur (28 triplets), Bihar (21 triplets), Maharashtra (20 triplets) and less than 20 triplets in rest of the states and union territories. In fact, there has been no attempt to document the tritrophic associations of this predator in several regions of India; therefore, a comprehensive survey plan is necessary to document them in those unexplored states/union territories.
