Abstract

After Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) was first detected in 2009, it quickly became the dominant pest in tomato-growing areas of Turkey. Both its feeding behavior and resistance to insecticides has forced growers to use alternative control measures. This study examined the effectiveness of individual and combined use of the predatory insect, Nesidiocoris tenuis (Reuter, 1895) (Hemiptera: Miridae) and the egg parasitoid, Trichogramma evanescens Westwood, 1833 (Hymenoptera: Trichogrammatidae) as biological control measures in the western Mediterranean Region of Turkey. For this purpose, greenhouse trials were conducted in a single-crop tomato cultivation period between 2011-2012 and 2013-2014. A reduction in infested fruit of 95.1 and 94.5% was achieved, respectively, in plots where N. tenuis and T. evanescens were released together. However, no significant difference was found between the plots with N. tenuis alone and the combination of N. tenuis and T. evanescens.

Özet

Domates güvesi, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)’nın Türkiye’de ilk defa 2009 yılında tespit edilmesinden sonra domates yetiştiriciliğinin yapıldığı alanlarda ana zararlı konumuna gelmiştir. Zararlının gerek beslenme davranışı ve gerekse insektisitlere karşı dayanıklılık oluşturması üreticileri alternatif mücadele yöntemleri kullanmaya zorlamıştır. Bu çalışma ile Batı Akdeniz Bölgesinde zararlı ile biyolojik mücadelede avcı böcek Nesidiocoris tenuis (Reuter, 1895) (Hemiptera: Miridae) ve yumurta parazitoidi Trichogramma evanescens Westwood, 1833 (Hymenoptera: Trichogrammatidae)’in tek başına ve birlikte etkinliklerinin belirlenmesi hedeflenmiştir. Bu amaçla, 2011-2012 ve 2013-2014 tek ekim örtüaltı domates yetiştirme periyodunda sera denemeleri yapılmıştır. Kontrol parsellerindeki bulaşık meyve oranına göre N. tenuis ve T. evanescens’ in birlikte salındığı parsellerde ilk yıl ve ikinci yıl çalışmasında sırasıyla, %95.1 ve 94.5 oranında azalma sağlamıştır. Bununla birlikte, N. tenuis ve N. tenuis +T. evanescens salınan parsellerde istatistiksel bir farklılık saptanmamıştır.
