The book "Newer Insecticides" offers a comprehensive analysis of the challenges posed by tobacco caterpillar infestations, particularly by Spodoptera litura. These pests are polyphagous and represent a significant threat to important crops such as cotton, peanuts, and mung beans. Over the past three decades, the resistance of these pests to conventional insecticides has increased significantly, highlighting the need for new chemical approaches to combat them. The book addresses the urgency of integrating insecticides with different modes of action to reduce selection pressures and extend the effectiveness of existing products in integrated pest management programs. It is particularly aimed at students of entomology and professionals in the field of plant protection who are interested in innovative solutions for pest control.
