Prediction of annual generations of the tomato leaf miner Tuta absoluta on tomato cultivations in Egypt

Abstract

Background: Tomato crop is the first vegetable crop in Egypt; it covers about 3% of Egypt's total planted area. The tomato leaf miner Tuta absoluta is a polyphagous insect pest which feeds on several solanaceous plant species and preferentially on tomato causing high losses in productivity. This study aims to predict the annual generations and expected times for moth emergence in order to select the best time for the pest management.
