Observational analysis correlates weather factors with pest dynamics in rice crops, highlighting ecological impacts.
On rainy season rice crop, gall miage, Orsectia cryzde Wood Masun and Yellow stemborar. Scirpophaga incertulos Walker are regular insect posts in War-angal region. As a part of Lasic studies in ecological aspects of these two pests an attemut was made to correlate the Important weather factors f'ke tempera-ture, rainfall and humidity of crop season (July-November), pre-season (June-August) and off season (March-June) with light trap catches and field inci-dences, recorded at the Agricultural Research Station, Warangal. The perio-dical field data of these two pests on a susceptible variety and light trop catchos of 1980 season alone were compared with the temperature, rainfall as well as key m rta ity factors like parasatization.
