Different Methods of Management Certain Substances to The Colored Pepper Crop in The Greenhouse to The Number of Western Flower Thrips Franklaniella Occidentalis (Pergande)

Abstract

Experiment was conducted during the spring seasons of 2021 and 2022 in the plastic house at North- South oriented at the experimental farm of Horticultural Research Stations Qaha, Qalyubia Governorate. The study aims to compare different methods of Management certain substances to the colored pepper crop in the greenhouse to the number of Western Flower Thrips (Franklaniella
occidentalis (Pergande)) this pest was attacking a wide spectrum of economic plants, causing great losses in their yield. Results showed that, Franklaniella occidentalis (Pergande) nymphs and adults had two seasonal generations during two seasons, the first generation occurred between early-April to end- April and the second generation was occurred between early- May to early – June. Using different treatments systemic pesticide (Ochen soil applied, Ochen foliar applied, Lannate soil applied, Lannate foliar applied, Movento soil applied, Movento foliar applied, Super tox soil applied, Super tox foliar applied, Dimethoate soil applied and Dimethoate foliar applied) were recorded in 2022 season (Movento soil applied and Dimethoate soil applied shows high mortality Therefore, it is preferable to use soil spraying. Lannate foliar applied indicated a low mortality effect on pest population.
