Temporal population dynamics of thripidae and aphididae in cotton and neighbour-crops

Abstract

Recently, the main challenge to increase cotton productivity worldwide is the plant susceptibility to pest attack. Studies into pest population dynamics are required to understand the complexity involving pest population fluctuation, and occasionally proliferation. Investigation into the interaction among pest population and abiotic and biotic factors such as temperature, precipitation, insecticide spraying, and other insect populations are still lacking, investigations that could provide information to lead a new path on pest management control. Therefore, in this study changing aspects on pests populations among cotton and neighbouring crops and their interaction with predicative variables was investigated. Considering cotton pest control based on the use of chemical products has shown several limitations. There is a need for better understanding on how the interactions among pest population, landscape complexity, agriculture management techniques, and climatic variables may affect pest dynamics in cotton crops.
