Insect Pest Management Under Climate Change

Insect responses to climate change are vital for knowing the response of agroecosystems to climate change. Although numerous insect species are pests in crops, yet they also play critical roles as parasitoids and predators for other key pest species. Changes in an insect population’s biochemistry, physiology, population dynamics, and biogeography may occur due to alterations in their distribution, among crop types and among the growing seasons . The response of an insect population to a quickly changing climate may also be inconsistent when insects have to interact with diverse competitors, parasitoids, and predators, and impose variable costs at a no. of life stages. The overall influence is on food production systems which can be already at acute risk from the influences of climate change. A significant limitation in improving crop production is the massive yield loss due to diseases, insect pests, and weeds all around the world. An unwise application of pesticides on crops has produced resistance among the insects and other pests and caused a severe effect on the economy of any country. This condition demands the need to endorse the idea of integrated pest management (IPM) among the farmers. IPM techniques are highly environment-sensitive that depend on the reasonable blend of physical, social, and biochemical control strategies utilized to control the pests, to minimize the economic loss and hazardous impact on the environment.
