Lasioptera sp. (Diptera: Cecidomyiidae)’ye farklı budama yöntemlerinin etkisi

Abstract

In this study, effect of cutting axial shoot in different ways and lengths on the egg-laying preferences of the females of Lasioptera sp. on tomatoes was determined. The study was conducted on naturally infected tomato plants in Antalya province in 2017. The experiment consisted of 5 characters (pruning at 5 and 8 cm long by scissors or manually and untreated control) with 100 replications. As a result, more pupae were counted in the scissors pruning groups than in the manual pruning axial shoots and the difference between two treatment was statistically significant (P<0.05). In the axial shoot pruning with scissors at 5 cm length 418 pupae and at 8 cm length 215 pupae were counted. No pupae were found to untreated control axial shoots that did not have any treatment, pruning or manual pruning, during the study. As a result, as reported in previous studies, overall the results showed that manual pruning the axial shoots at 5-8 cm lengths could reduce the damage of this insect by approximately 87%, and suggest that this method can be effective in controlling this harmful species by reducing its egg-laying activity.
