The nymphal stage passed through five  instars. The female inserted eggs into leaf tissue.  The total duration of life cycle was 18 to 30 days  in case of male, while it was 20 to 34 days in case  of female at an average temperature of 31.30 ± 1.96° C and the relative humidity of 73.96 ± 3.02 per  cent. The genotypes \/ varieties GG-5 and GG-2 were  found least susceptible to jassid. Two type of  predators viz., Chrysoperla carnea (Stephens) and  Crossopalpus sp. were found in the field. The  treatments monocrotophos 0.04 per cent, methyl-o- demeton 0.025 per cent and dimethoate 0.03 per cent  were found most effective for the control of jassid  under field conditions. Considering the yield and  economics, two sprays of monocrotophos 0.04 per cent  gave maximum yield of groundnut pod and haulm (2014  kg\/ha and 2812 kg\/ha) and the highest cost benefit  ratio of 1:19.85 followed by methyl-o-demeton 0.025  per cent (1910 kg\/ha and 2622 kg\/ha) (1:17.94) and  dimethoate 0.03 per cent (1806 kg\/ha and 2413 kg\/ha)  (1:18.27).\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844397406\"\u003e\u003ch3\u003eBionomics, Varietal Screening and Chemical Control of Jassid (Empoasca kerri Pruthi) in Summer  Groundnut\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844397406","offer_id":39471235563613,"sku":"9783844397406","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e27dfff0-283f-4b57-9205-ef489bb93eb6.jpg?v=1758778589","url":"https:\/\/shop.autorenwelt.de\/products\/management-of-jassid-empoasca-kerri-pruthi-in-summer-groundnut-von-a-v-khanpara","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
