Management of the Whitefly Bemisia tabaci (Genn.) on Melon by Vacuum Removal
1999
Weintraub, Phyllis G. | Horowitz, A Rami
The efficacy of a field vacuum unit for the management of Bemisia tabaci was evaluated on melon (Cucumis melo L.) during two summer seasons. The tractor-mounted unit was designed to dislodge insects by blowing air from lateral vents onto the plants while simultaneously vacuuming from above. Field observations, collection of leaf samples, and hand-vacuum sampling before and after the field vacuuming were used to evaluate the efficacy of removal. Bemisia tabaci population reductions were significant (30–60%) and lasted from week to week when vacuumed weekly. Parasitoid populations were slightly affected, but were not significantly different from populations in the untreated control plot. Field vacuuming was found to be as effective as insecticide applications for the control of B. tabaci in melons.
