Abstract: In order to compared the effect of different tobacco extracts on the population buildup of sucking complex in okra crop at experimental field of Latif Farm Sindh Agriculture University Tandojam. The following leaf extracts of tobacco varieties (T1= Hazaropattar tobacco, T2= Desi tobacco, T3= Balkhi tobacco, T4= Gurakhu tobacco and T5= Control were distributed and sprayed on the crop. The observations were recorded on population of white fly, jassids and aphid before and after spraying. The results showed that the efficacy of different tobacco extracts against major sucking insect pests at different treatments. Average reduction in the population of white fly on spray were 58.02%, 65.23%, 68.74%, and 71.46%, examined for T1, T2, T3 and T4, respectively. The results indicated that maximum mean reduction in the population of white fly against different tobacco leaf extract were examined for T4 (86.58%) followed by T3 (85.95%), T2 (83.71%), and T1 (79.83%). The average reduction in the population of jassids on spray was 47.31%, 37.22%, 34.76% and 54.81% examined for T1, T2, T3 and T4, respectively. Further results indicated that maximum population reduction of jassids against tobacco leaf extracts on spray were examined for T4 (88.51%) followed by T1 (83.99%), T2 (76.14%), and T3 (74.28%). Furthermore an average population reduction of aphids on spray was 54.71%, 53.86%, 53.60% and 63.55% examined for T1, T2, T3 and T4, respectively. The results indicated that the maximum population reduction of aphids against tobacco leaf extracts on spray were examined for T4 (92.22%) followed by T3 (87.75%), T1 (86.99%) and T2 (85.89%).
