Paperback. Condición: New. Print on Demand. This work delves into the spring grain-aphid or the green bug, a tiny but formidable pest whose feeding can entirely demolish wheat and oat crops. The author delves into the history of its discovery and the subsequent outbreaks that have ravaged crops since 1890. One of these outbreaks…, in 1907, was the worst ever recorded and the book explores the reasons behind its virulence and spread. The author also details the discovery and use of Aphidius, a parasitic wasp that controls this pest, explaining their life cycles and methods of controlling the green bug. The book concludes by highlighting the importance of understanding the factors that influence the abundance of pests like the green bug, emphasizing the need for reliable forecasting and the implementation of integrated pest management strategies to mitigate their impact on agriculture. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
