Paperback. Condizione: New. Print on Demand. This book, the culmination of years of entomological research and observation, delves into the parasitic relationships between insects and the infamous cotton boll weevil. The author meticulously chronicles the biological characteristics, seasonal distribution, and geographic prevalence of fifteen species of insects that prey upon the boll weevil. These parasites, identified as primary enemies of the weevil, include hymenopterans, dipterans, and acarid species. Furthermore, the book explores the predatory habits of two species of beetles and two ant species that contribute to the natural control of the boll weevil. Detailed observations and tabulated data provide a comprehensive understanding of the complex interactions between these organisms and their host. The author's insights shed light on the potential for employing these beneficial insects as biocontrol agents in combating the devastating effects of the boll weevil on cotton crops, offering hope for sustainable solutions in modern agricultural practices. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
