Description An experiment was conducted during 1989-90 and 1990-91 to study the effect of weather factors on activity of citrus leaf-miner (Phyllocnistis citrella Stainton) infesting lime [Citrus aurantifolia (Christm.) Swingle]. The larval population of leaf-miner was higher during August-September than during the rest of the period. The minimum temperature (r= 0.58) had positive association. whereas sunshine hours (r= -0.59) and vapour-pressure deficit (r= -0.43) had negative association with leaf-miner population. The minimum temperature more than 18°C, vapour pressure more than 20 mm Hg and sunshine less than 6 hr favoured the multiplication ofleaf-miner. The individual factor showed 35% effect, whereas their combined effect by step-wise regression analysis did not exceed 9%.
