Management of the whitefly Bemisia tabaci (Genn.) on melon by vacuum removal
Insect Science and its Application 19 (2-3), 173-178
Abstract: 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 (3060%) 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.

Des essais ont été réalisés en champ durant deux ans afin dévaluer lefficacité dun appareil à succion en vue de la lutte contre B. tabaci (Genn.). Lunité a été conçue pour déloger des insectes en soufflant de lair sur des plants de façon latérale et, simultanément en aspirant les insectes par une bouche située au-dessus. On a utilisé des observations au champs, la collecte déchantillons de feuilles et laspiration manuelle pour évaluer lefficacité. Des réductions significatives (3060%) de populations ont été observées et elles duraient une semaine. Les populations de parasitoïdes ont été légèrement affectées, mais les populations nétaient pas significativement différentes de celles estimées dans les parcelles témoins. En parcelle de melons, laspiration a donné un niveau de contrôle égal aux applications insecticides.
