Özet

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.
