Researches regarding the chemical and integrated control of the greenhouse whitefly, Trialeurodes vaporariorum Westwood, in protected areas cultivated with tomatoes.

Abstract

The aims of this study was to establish for the control of the greenhouse whitefly Trialeurodes vaporariorum Westwood, the further actions to be taken, using traditional pest control methods and correlating them with the use of unconventional ones (use of coloured sticky boards). The experiments were carried out in 2008 in the greenhouse located in Colonia Borhanci, cultivated with extra-early tomato hybrids: Menhir F1, Cronos F1, Shannon F1. The research shows that the chemical insecticides having a systemical action, Mospilan 20 SG (acetamiprid 200 g/l), Emerite (imidacloprid 240 g/l) where more effective than those products having contact and ingestion actions, Talstar 10 EC (bifetrin 100 g/l), Vertimec 1,8 % EC (abamectin 18 g/l), Decis 2,5 EC (deltametrin 25 g/l) and Faster 10 CE (cipermetrin 100 g/l). Applying a complex strategy to prevent and control of greenhouse whitefly Trialeurodes vaporariorum Westwood it was developed a strategy of integrated control in protected areas. Utilization of sticky traps is an ecological method and the panels can be handled easily.
