Lasioptera sp. is one of the problematic pests in the Mediterranean and Aegean regions where protected tomato cultivation is done in Turkey. The larvae that cause tunnel and deteriorations in the plant's main stem by feeding on the core part of the body mostly lead to the death of the plant in a dense pest population. Since harmful larvae live in plant tissue and thus are protected against insecticides and biological agents, control of the pest is very crucial. As an alternative method to pest
... ive method to pest control, the effects of tomato axillary shoot pruning for controlling the pest were examined. For this purpose, while pruning of axillary shoots in tomato plants as recommended in cultural processes, shoots that are cut off from the body completely and stub-pruning sprouts with 3-5 cm length were assessed in the experiment. The study was carried out in Erdemli district of Mersin province in 2015 and 2017. Although it is ensured that the harmful larvae can feed inside stubpruned shoots left on the body, the larvae could not reach the plant's main stem and do not cause any damage to the plant. In terms of damaged plants, it was determined that 77.8% and 85.2% of the stub-pruning application are effective in 2015 and 2017, respectively. Additionally, in the study, the attractiveness of visual sticky traps in six different colors including, yellow, black, blue, white, red, and green was investigated. As a result of the study, it was concluded that the colors tested were not sufficient to attract pests.
