The book "Biological Control of Flower Thrips" offers a comprehensive analysis of the challenges associated with the use of chemical pesticides in agriculture, particularly in the cultivation of green beans. Given the increasing issues such as pest resistance and environmental damage, the need for a more environmentally friendly approach to pest control becomes evident. This specialized book thoroughly examines the potential of entomopathogenic nematodes, specifically Heterorhabditis bacteriophora and Steinernema karii, as biological control agents against flower thrips, such as Frankliniella occidentalis and Megalurothrips sjostedti. It is aimed at professionals, researchers, and anyone interested in sustainable solutions for pest management. The authors, Charles Waturu, Linus Gitonga, and Joseph Nganga, provide valuable insights and practical approaches to biological pest control in this important area of agriculture.
