Abstract:
A detailed studies on survey on major insect pests of chilli in Marathwada region was conducted during 2017. Collection of data on pest infestation was done by visiting random fields and those were sampled from each Tahasil of Marathwada region by adopting survey procedure i.e. five random spots in each field were selected and from the same spot five random plant representative of all the cropped area were selected to record sucking pests and fruit borer and in the one season same location was visitied twice. During 2017, thrips population was ranged between 0.48 thrips/ leaf (Sengaon tahasil of Hingoli district) to 9.98 thrips/leaf (Biloli tahasil of Nanded district). The whitefly population across all location was ranged between 1.08 whiteflies/leaf to 5.68 whiteflies/leaf. Aphid incidence was noticed in this region, but was confined to Parbhani, Hingoli and Nanded districts only and in all other region it was completely absent in both season and ranged from 0.00 to 9.98 aphids/leaf. Mites infestation on chilli was uniform in all locations and it was also noticed at later stage of the crop in both the seasons and it was ranged in between 4.42 to 8.96 mites/ leaf, respectively. In case of fruit borer very less infestation 0.00 to 2.40 larvae/ plant during 2016 and 2017 was recorded. This suggests the moderate to high pest infestation on chilli in Marathwada.
