Özet (Çeviri)
Glasshouse Whitefly, Trialeurodes Vaporariorum, is one of the most economically significant pests in terms of its damage to vegetable crops in glasshouse conditions. It can damage vegetable crop, such as tomato and cucumber, easily. Chemical control was applied against this pest, but resistance has prevented the use of chemical control methods. In addition, chemical pesticides pollute the environment. Alternative methods are now being developed as an alternative to chemical control. Biological control, therefore, is one of the viable alternative methods being use in the control of Glasshouse Whitefly. The aim of this present research is to use of biological control against Glasshouse Whitefly. Biological control using a parasitoid was used in this investigation. Encarsia formosa is well-known bio-control agents for Glasshouse Whitefly. The effectiveness of Encarsia formosa was observed between three different varieties for this study. Two tomatoes (Moneymaker and Alicante) and one cucumber (Telegraph Improved), varieties were selected for this experiment. No significant difference was identified between the three varieties in terms of the parasitism rate. The percentage of parasitism is 67% for Moneymaker, 67% for Alicante, and 62% for Cucumber. The rates are similar to each other. No significant difference was identified between treatment and control plants with regard to the total number of eggs, but there was a different noted between Alicante and Cucumber in this study. According to projected results, the biological control using Encarsia formosa against Glasshouse Whitefly is a successful method in the glasshouse conditions. This method can be used on tomato and cucumber plants for the control of Glasshouse Whitefly, Trialeurodes Vaporariorum, in glasshouses.
