Effect of weather parameters on pest population dynamics of major pests of gerbera in different growth media under polyhouse conditions

摘要

Insect infestation on gerbera was generally higher under high temperature and low relative humidity in case of mites, thrips and leaf miner. Mite and leaf miner population was negatively correlated with absorbed radiations, while thrips were positively correlated with absorbed radiation. Mite, leaf miner and thrips were positively correlated with canopy temperature. Treatment, cocopeat + red soil + FYM + vermicompost + at the proportion of showed 40:30:10:10:10 respectively was promise in reducing pestspopulation.
