ABSTRACT

Brinjal (Solanum melongena) is a very important and nutritious vegetable grown in tropical and subtropical regions of the world. Both nymphs and adults of Amrasca bigutulla bigutulla suck the cell sap from underside the leaves resulting in leaves curling and yellowing. Jassid (Amrasca bigutulla bigutulla) inject toxic materials into leaves which results necrosis. An experimental study was conducted by using randomized complete block design (RCBD) during 2018 to check the resistant brinjal varieties (Nirala, Dilnasheen and Bemisal) against jassid (A. bigutulla bigutulla). The highest population of jassid was recorded on 5 November while lowest on 2 December on all tested varieties. The population density was lowest in December on all varieties such as Nirala (1.0), Dilnasheen (2.1) and Bemisal (1.2), while maximum in November such as Nirala (3.8), Dilnasheen (6.6) and Bemisal (4.2) per leaf. Bemisal and Dilnasheen varieties had significantly higher jassid population per leaf as compared to Nirala variety on different sampling dates.
