PREFERENCE AND PREFORMANCE OF <i>BEMISIA TABACI</i> (GENNADIUS) ON DIFFERENT HOST PLANTS

Host preference and development biology of Bemisia tabaci (Gennadius) on brinjal, soybean, cucumber, cotton, tomato Solanum nigrum L. was studied during 2020-21 at PAU, Ludhiana. Under free choice test conditions, cucumber the most preferred host which attracted maximum number adults followed by soybean. The other plants in decreasing order were cotton > brinjal S.nigrum. Brinjal suitable hosts having shorter period, higher survival fecundity. immature stages soybean 50% as compared to 67.5-72.5% i.e. brinjal. Thus, is a for adult feeding andoviposition but less B. tabaci. Hence, may be exploited atrap crop management
