On occurrence of Major Pests on the Trimmed Surface of Tea Plants in Relation to Temperature and Relative Humidity -An Approach towards Minimal Use of Pesticides

Abstract

Assemblage of tea pests were studied in relation to environmental factors aiming at working out conditions promoting maximum occurrence on the surface of trimmed tea plants and thereby ensuring minimal use of pesticides and damage to the human workers resulting from chemicals. Atmospheric temperature and relative humidity tended to render a positive impact on the occurrence of the pests on plant surfaces, as indicated by correlation analyses, regression lines and the principal component analysis.
