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.

The World

Tomato (Solanum lycopersicum L.) is a very important vegetable crop of the world. However, there is a huge loss in tomato production due to pest and disease incidence. Tomato leaf miner is a devastating pest of tomato and other Solanaceous crops in many vegetable crop growing areas around the world and it also attacks non-solanaceous crops. The larva is the most devastating stage of tomato leaf miner. After egg hatching, the larvae feed on tomato fruits, leaves, flower buds, and young shoots and create mines and galleries. Larval feeding may reduce tomato production by 80-100 % in an open field as well as in a plastic house if no control measures are carried out. Chemical control has been found ineffective due to a wide host range and has developed resistance to dozens of pesticides. Hence, Integrated Pest Management (IPM) practices involving mass trapping of the pest using pheromone trap, biological control by a predator, parasitoid, entomopathogenic microbes, including cultural practices should be implemented for the effective control of this pest.

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.
