This study was carried out to determine the extensity, development of population and the state of damage of tomato leaf miner (Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)) in total eight tomato fields located in the villages of Goktepe of Central Sanliurfa, Meteler of Birecik, Kepirce of Bozova, Yalcinkaya of Ceylanpinar, Ovacik of Hilvan, Kucuk Yucelen of Siverek, Aligor of Suruc and Ciftciler of Viransehir in 2011. To determine the extensity of tomato leaf miner each of the 5 districts in the village tomato field was checked by observation whether adult or larvae found in fields T. absoluta. The result showed that tomato leaf miner was common in all the districts. The highest density of tomato leaf miner adult population quantities were 630, 800, 400, 965, 211, 600, 215 and 96 pcs/week in Goktepe of Central Sanliurfa, Meteler of Birecik, Kepirce of Bozova, Yalcinkaya of Ceylanpinar, Ovacik of Hilvan, Kucuk Yucelen of Siverek, Aligor of Suruc and Ciftciler of Viransehir, respectively. Tomato leaf miner harmed the fruits, particularly total in 1st and 2nd harvest of tomato (the end of August- the beginning of September) , if precautions were not taken. Moreover, it was recorded that if the adult population was quite dense in the fields study conducted, there aren’t any undamaged leaves and fruits from T. absoluta.

Abstract Background In this study, commercial bioinsecticides including entomopathogenic fungi, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, and Spinetoram active ingredient insecticide were evaluated against the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) larvae. Main body The active ingredients were prepared at the recommended concentrations under laboratory conditions and applied to the 2nd instar larvae of T. absoluta by spraying with a hand sprayer. On the 1st, 3rd, 5th, and 7th days of the application, evaluations were made by counting survived individuals. The findings showed that the highest mortality rates were detected in the case of Spinetoram with 56, 60, 88, and 100% on all counting days of the experiments, respectively. The highest mortality rate among bioinsecticides was recorded for M. anisopliae, with 87% mortality on the 7th day of application. Short conclusion As a result, Spinetoram was found the most effective insecticide when applied to T. absoluta, followed by M. anisopliae.

Seasonal activity and population fluctuation of tomato leaf miner, Tuta absoluta (Meyrick), a dangerous pest of tomato fields in Tehran province, were determined in Varamin region, south of Tehran province in 2015-2016. Number of moths in pheromone trap and number of larvae per plant were counted weekly in a trail tomato field. The trap capture began on mid-April in warm dry spring of 2015 and on mid-May in cool wet spring of 2016. The first and highest moth peaks in trap occurred about one month earlier in 2015 than 2016. The larval density per plant at the highest peak reached 2.34 and 10.8 in 2015 and 2016, respectively. A temperature range of 25-30°C was desirable to the pest in which the interval of successive peaks decreased. In both years, the pest created three generations over a growing season, according to larval peaks, but 11 over a year, according to trap data, that the 11th generation overwintered. The temperature of 35°C and above limited larval activity and decreased the population. After the crop removed, the pest population declined due to host shortage, but it increased with the access of hosts in the second cultivation since mid-September until the cold season.
