The effectiveness of Encarsia formosa Gahan (Hym: Aphelinidae) against Glasshouse Whitefly (Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)) under glasshouse conditions

Abstract

Glasshouse whitefly Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae) is one of the most economically important pests in terms of its damage to vegetable crops in glasshouse condition. Chemical control is still applied against this pest, but resistance has prevented the use of chemical control methods. In addition chemical pesticides pollute the environment. Biological control, therefore, is one of the viable alternative methods being use in the control of Glasshouse whitefly. The aim of this present study is to use of biological control against Glasshouse whitefly. The effectiveness of Encarsia formosa Gahan (Hymenoptera: Aphelinidae) was observed between three different varieties of the tomato and cucumber (Moneymaker (tomato), Alicante (tomato) and Telegraph Improved (cucumber)) for this study The results obtained from present study indicated that the percentage of parasitism was 67% for Moneymaker, 67% for Alicante, and 62% for Telegraph Improved. While there was no significant difference in the percentage of parasitism, there was only a difference in the number of whitefly eggs laid between in variety of Alicante ((tomato) and Telegraph Improved (cucumber) in this study. According to the results, the biological control using E. formosa against Glasshouse whitefly can be used successfully on varieties of Moneymaker (tomato), Alicante (tomato), and Telegraph Improved (cucumber) for the control of Glasshouse whitefly in glasshouses.

Öz

Sera Beyazsineği Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae) sera koşullarında yetiştirilen sebze ürünlerinde ekonomik açıdan zarara sebep olan önemli zararlı türler arasında yer almaktadır. Kalite ve verim açısından zarara sebep olan bu tür için kimyasal mücadele yaygın bir şekilde uygulanmaktadır. Ancak kimyasal mücadele bu zararlıda dayanıklılığa sebep olmakta ve kullanılan kimyasal pestisitlerin çevreye zarar verdiği bilinmektedir. Geliştirilen alternatif mücadele yöntemlerinden olan biyolojik mücadele bu zararlının kontrol altına alınmasında kullanılabilecek bir yöntemdir. Yapılan bu çalışmanın amacı, Sera Beyazsineğine karşı ticari olarak da kullanılan Encarsia formosa Gahan (Hymenoptera: Aphelinidae)’nın etkinliğinin Moneymaker ve Alicante adlı domates ve Telegraph Improved adlı hıyar çeşitlerinde araştırılmasıdır. Bu projeden elde edilen sonuçlara göre parazitlenme oranlarında (Moneymaker için %67, Alicante için %67, Telegraph Improved için %62). bir farklılık gözlenmemiştir. Sadece Alicante ve Telegraph Improved çeşitlerinde Sera Beyazsineğinin bıraktığı yumurta sayısı açısından bir farklılık tespit edilmiştir. Sonuç olarak, E. formosa’nın Sera Beyazsineğine karşı bu çalışmada kullanılan Moneymaker ve Alicante isimli domates ve Telegraph Improved isimli hıyar çeşitlerinde sera koşullarında kullanılabilecek başarılı bir parazitoit olduğu görülmüştür.
