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.
