The study on organic management of fruit fly species on jujube (ber) ecosystem was carried out in the laboratory of Sindh Agriculture University, Tando Jam from November 2008 to March 2009. The data on efficacy of bio-pesticides on fruit fly specie was recorded from heaps of ripened fruits during harvesting and from fallen fruits on ground. The data from heaps of ber fruits indicated that infestation was 1.5, 5.5 and 12.1 % when treated with neem powder, tobacco extract and control, respectively on 7 th October. The maximum was 8.11, 20.5 and 50.75 % infestation was observed when treated fruits by neem powder, tobacco extract and control, respectively on 21 st November. Infestation percentage decreased and it reached 0.75, 3.12 and 10.75 % after the spray of neem powder, tobacco extract and control, respectively. The data revealed the overall mean efficiency of different bio-pesticides was neem powder (4.12), followed by tobacco extract (10.16) and control (27.11) respectively. The infestation of fruit flies of fallen fruit was started from 7 th October and it was 9.02, 18.5 and 30.76 % when treated with neem powder, tobacco extract and control, respectively. The maximum was 40.22, 56.6 and 79.9 % infestation was observed when treated by neem powder, tobacco extract and control, respectively on 21 st November. After that, infestation percentage decreased and reached 6.66, 7.14 and 19.51% after the spray of neem powder, tobacco extract and control, respectively. It is found that three species of fruit fly infest the jujube fruits. The fruit fly Bactrocera zonata occurs in large numbers up to 80.1% population. The rest of two species Bactrocera dorsalis and Corpomyia vasuviana occur 12.3 and 7.6 % respectively. In the light of experiment, it could be recommended that neem powder and tobacco extract can be applied for controlling of pests on jujube (ber) orchards.
