Abstract
The present studies on screening of some brinjal cultivars against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee) was carried out during 2016 in the field conditions in the Department of Entomology, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan. Eight brinjal cultivars viz. 'Brinjal Long (F1)', 'DS-407', 'Ganesh', 'Long Green', 'Neelkanth', 'Prapti', 'Pusa Purple Cluster' and 'Pusa Purple Long' were evaluated against brinjal shoot and fruit borer, L. orbonalis (Guenee) under field conditions. Egg and larval count of L. orbonalis was made on these cultivars. The per cent shoot infestation in different brinjal cultivars were evaluated on basis of number of shoot damaged. None of the cultivars were found to be tolerant to shoot attack of L. orbonalis infestation but considerable variation of infestation was recorded among different cultivars. The per cent fruit damage varied from 6.66% to 46.63% recording the minimum fruit infestation in 'DS-407' and 'Ganesh' while the maximum fruit infestation was observed in 'Prapti' which was at par with 'Pusa Purple Long' and 'Neelkanth'.
