Abstract

Experiments were conducted in the experimental Horticulture Research Station in Qaha city, Qalubiya Governorate under greenhouse conditions during two successive seasons (2016-2017 and 2017-2018). The study aims for managing of pests attacking tomato, Lycopersicon esculentum (Mill.) plants and their relationship with product yield, by using insecticides, orange oil and mineral oil alone and in binary mixtures, their relationship with crop yield under the greenhouse. Bemisia tabaci (Genn.), Tuta absoluta (Meyrick) and Tetranychus urticae (Koch) were the most important pests found on a tomato plant. These pests are causing great losses in tomato yield. Results showed that using Actara binary mixtures with mineral oil or orange oil binary mixtures with mineral oil have a highly significant effect on decreasing pests population infesting tomato plants and improving actual yield. The insecticide binary mixtures with mineral oil have an effect on population pests whereas decreased the mean number of pests and were the most efficient method compared to without treatment area.
