Abstract

Malathion (1.12 kg of AI/ha) effectively reduced populations of biotype E greenbugs, Schizaphis graminum (Rondani), within 24 h at temperatures below 10°C, whereas comparable control with parathion (0.28 kg of AI/ha) required 3 days. Control with parathion was more rapid (2 days) between 10 and 18.9°C. Dimethoate (0.37 kg of AI/ha) did not reduce green bug populations to acceptable levels at 18.9°C. Malathion, parathion, and dimethoate reduced high populations between 23.8 and 30°C. Untreated populations of S. graminum significantly reduced wheat yields.
