Book excerpt: Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i

Download or read book Evaluating the Non-Consumptive Effects of Insect Predators on Aphids and Aphid-Borne Virus Transmission written by Benjamin Walter Lee and published by . This book was released on 2021 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predators exhibit "consumptive effects" (CEs) by capturing and consuming prey, while exhibiting "non-consumptive effects" (NCEs) on prey physiology and behavior through failed attacks that influence their perception of risk in the environment. Predatory insects are widely used to control agricultural pests, including insect vectors of pathogens, though their role in affecting pathogen transmission has been poorly understood. This dissertation evaluates a range of predation effects on aphid vectors and their transmission of Pea enation mosaic virus (PEMV), an economically damaging aphid-borne pathogen of legumes grown in the Pacific Northwest USA. The first chapter discusses difficulties in predicting vector-borne virus transmission using mathematical models, as vectors' interactions with other species can unpredictably affect rates of pathogen transmission. The second chapter documents a field study evaluating predator CEs and NCEs on aphid vector abundance, movement, and feeding behavior and how these effects contribute to aphids' ability to transmit PEMV. Analysis using structural equation modeling revealed predators indirectly increased PEMV prevalence by inducing aphids to disperse to new hosts and feed upon parts of the host plant on which pathogen transmission is greater. The third chapter details several greenhouse experiments examining how vector responses to signals of predation risk affect transmission of PEMV. I found that chemical cues left by predators or alarm pheromones released by conspecifics reduced aphids' ability to acquire and transmit PEMV but had no effect on their fecundity or nutrition. The final chapter describes a field study examining how diverse predator communities affect aphids and PEMV transmission. When multiple predator species feed on aphid vectors, their effects on aphid abundance can be synergistic or antagonistic, though the impacts of predator diversity on aphid behavior and transmission efficiency are unknown. I find that predator diversity enhanced aphid suppression but altered aphid behavior in ways that increased virus transmission, resulting in no net change in PEMV prevalence. This final chapter suggests that the benefits of increasing diversity for pest suppression may not similarly influence disease risk. This dissertation improves our understanding of how insect predators affect plant pathogen transmission and will inform management strategies using natural enemies to combat plant pathogens.

This book was released on 2013 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on the biology of P. trinotatus on A. craccivora indicated that the lady bird beetle did not lay eggs on leaves under the laboratory condition when fed on A. craccivora. However, they were laid on under surface of the lid of the container near to the grooves. The average fecundity of the female was 142.76 17.75 eggs.The average longevity of male and female was 26.40 3.017 and 30.80 2.515 days, respectively. Total life cycle occupied on an average of 50.78 3.495 days by male and 55.18 3.348 days by female. During entire life period of P. trinotatus consumed on an average 171.69 13.17 aphids when reared on A. craccivora. Biology of C. carnea on A. craccivora revealed that the freshly laid eggs were stalked, oval and pale green in colour, which turned to dark grey prior to hatching. The average egg producing capacity of gravid female was found to be 509.96 77.43 eggs/female. Total life cycle occupied was of 50.25 4.389 days in male and 58.58 3.357 days in female under the laboratory condition. A single predatory larva consumed on an average 397.32 38.86 aphids during its developmental period.

Indeed, among the 4000 or so known species of aphids about 250 are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as v

Available in PDF, EPUB and Kindle. Book excerpt: To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139μm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica; in caves, under the ground, inside plants, other insects and vertebrates, in rivers, streams, lakes and ponds, in puddles, in the watery interiors of pitcher plants; and in our houses. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans. This Very Short Introduction explores the extraordinary world of insects. It analyses insect evolution, taxonomy and development, and describes their behaviour, their life styles, and the interactions they have with other insects and other animals. As Simon Leather shows, insects are the bedrock on which human civilisation rests; without them we would almost certainly not exist. Although they can be seen as pests of our crops plants, they are also invaluable for pollinating our flowering plants and are an invaluable link in all land ecosystems. As they face challenges from climate change and pesticides it has never been more important to understand these oft-dismissed creatures. Very Short Introductions: Brilliant, Sharp, Inspiring ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
