The Potential for Genetic Suppression of Insect Populations by Their Adaptations to Climate (Classic Reprint) - Softcover
Inhaltsangabe
Excerpt from The Potential for Genetic Suppression of Insect Populations by Their Adaptations to Climate<br/><br/>Examination of cases 2-6 in table 41 shows that when a conditional lethal trait is deter mined by more than one gene, the trait may be expressed in a progressively higher proportion of individuals from generation to generation. Cases 7 Â 15 show that when the release strain possesses more than one conditional lethal trait, the efficiency of suppression is progressively augmented in succeeding generations. If the conditional lethal traits were expressed in the last generation of the season, release ratios ranging from to would be adequate to decimate most populations with four genera tions per year. This would require releases ranging from 100 to 500 insects per acre when the natural population consists of 10 insects per acre. Higher ratios would be required if the species had fewer than four generations per year. In most instances these ratios would have to be two to five times higher to achieve the same suppression in the F2 as in the F4.

Paperback. Zustand: New. Print on Demand. This book delves into the fascinating and complex world of insect population control, exploring a revolutionary approach that leverages the very adaptations insects have evolved to survive in different climates. The author examines the concept of "conditional lethal traits," genetic variations within insect species that are harmless in their natural environments but can become fatal under specific conditions. The book explores how these traits, often related to an insect's ability to enter diapause (a state of dormancy) or withstand cold temperatures, can be exploited to suppress or even eradicate pest populations. The author presents a detailed analysis of how these traits might be used in conjunction with other control methods, such as partial sterility, to achieve lasting and environmentally-friendly solutions to insect infestations. Through mathematical models and detailed examples, the book meticulously lays out the potential of this innovative strategy, offering a compelling case for its future application in insect control. The book's insights hold significant promise for developing more sustainable and effective methods to manage insect populations and protect crops and ecosystems.
