The effect of microclimatic parameters on population dynamics of tomato whitefly

Abstract

The present study entitled as “Effect of population dynamic of whitefly and different transplanting dates on yield of tomato (Solanum lycopersicum) under climatic conditions of Allahabad” was conducted during rabi season 2017-2018 at the field Experimentation Center of Department of Genetics and Plant Breeding, SHUATS, Allahabad. The experiment was laid out in Factorial Randomized Block Design in three dates of transplanting (10, 20 and 30 November). Results revealed that the maximum temperature, wind speed and bright sunshine hours were negatively correlation to population on whitefly at fifth standard week due to sudden fluctuation of weather parameters while at the same time growing degree day and humid thermal ratio showed a positive correlation to whitefly population. Therefore climate change would result in changes in the population dynamics of insect pests. Thus temperature rise plays a pivotal role in insect population dynamics.
