Partial spray of the bio-insecticide spinosad bait versus spinosad on cucumber and squash to combat the lesser pumpkin fly, Dacus ciliates (Loew) [electronic resource].

Includes references.

Experiments were conducted to test the performance of two formulations from the bio-insecticide, Spinosad against the lesser pumpkin fly, Dacus cilia/us (Loew) at the Farm of the Environmental Studies and Research Institute, Minufiya University, EI Sadat distric~ Egypt during the two growing seasons 2007 and 2008. Two cucurbit cultivars; squash and cucumber were used in the study. GF-120 (Spinosad bait 0.024% CB), as a partial spray as well as its conjunction with sticky traps showed significant results than the full cover spray of Tracer (Spinosad 24% SC) on both crops, expressed as numbers of infested fruits, developed pupae and emerged adults. Tracer 24 % SC, as full spray or sticky traps alone did not show satisfactory results. Although the GF-120 bait contains 1000 times lower than Spinosad (24%), as active ingredients, the performance of the first one was significantly much better as pest control agent than the 2"" formulation due to its attraction power. Obtained results indicated that the pest was very sensitive to this type of formulation even when it contains a very low amount of active ingredients of Spinosad.
