- A field study in the experimental area of Entomology Section, Agriculture Research Institute, (ARI) Tandojam Sindh Pakistan was carried out so as to examine the efficacy of different biopesticides against the cauliflower white fly. Seven treatments with three replications that: T1=chemical control (confidor), T2=Neem (Azadirachta indica), T3=Akk (Calotropis procera Alton. F.), T4=Tooh (Citrullus colocynthus Schrad. L.), T5=Datura (Datura stramonium) T6=Tabacco (Nicotiana tabacum) and T7=Control (untreated) were applied and white fly infesting in cauliflower plant was found. In this regard, the pre and post-treatment observations were also recorded. Against whitefly, chemical control (confidor) showed highest efficacy (95.75%) as observed during 1st spray, followed chemical control (confidor) (91.89%), Tooh extract (83.81%) and least efficacy for Dhatura extract (78.14%); while after second spray also, chemical control (confidor) showed highest efficacy (86.36%), followed by Neem extract (73.58%), Tobacco extract (75.11%), Tooh extract (70.67%), Akk extract (70.05%) and the lowest efficacy was resulted by Dhatura extract (66.63%). According to the overall efficacy of biopesticides against whitefly after first and second spray, the treatments ranked as: chemical control (confidor), neem extract, tobacco extract, tooh extract, akk extract and dhatura extract respectively
