Download or read book Some Ant aphid Associations in Manitoba with Observations on Interactions Between Formica Oreas Comptula Wheeler and Aphids at Birds Hill Park Manitoba written by Mary Catherine Anne Madder and published by . This book was released on 1978 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: ... A survey of Manitoba ant-aphid associations was conducted by collecting and identifying samples of ants and aphids found together on aphid host plants. Qualitative and quantitative monitoring of the interactions of Formica oreas comptula with Symydobius americanus, Chaitophorus saliciniger and Pterocomma smithiae was carried out during 1977 at Birds Hill Park. Data were analyzed by stepwise multiple linear regression analyses. Twenty-seven species (seven genera) of ants tending 62 species (28 genera) of aphids on 39 host plants were collected in Manitoba during 1976 and 1977. Formica species were the dominant aphid-attendants and Aphis species wee the most frequently attended aphids. 9.7% of the associations contained two different ant species or genera together; usually one was the true aphid-attendant and the other a scavenger species. F. oreas comptula workers were always present at the aphid colonies, at least until mid-June; however, the individual aphid-attendants changed throughout the day and night. Demand for aphid honeydew diminished by mid-June, possibly due to departure of males and queens from the ant nest. Aphid excretory behavior changed when this decrease in ant attendance occurred, and other ant species were then frequently observed at or near the aphid colonies. Marking experiments suggested that age polyethism and task fidelity exist in F. oreas comptula, and that some ants which were present at the aphid colonies in the spring may have been foragers surviving from the previous summer ... F. oreas comptula were aggressive toward moving insects near the aphid colonies they were tending; they did not respond to syrphid larvae feeding on the aphids. Aphid parasitism and predation were not prevented by the ants' presence, and were greatest in colonies of C. saliciniger.

Download or read book Ecofriendly Pest Management for Food Security written by Omkar and published by Academic Press. This book was released on 2016-02-03 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecofriendly Pest Management for Food Security explores the broad range of opportunity and challenges afforded by Integrated Pest Management systems. The book focuses on the insect resistance that has developed as a result of pest control chemicals, and how new methods of environmentally complementary pest control can be used to suppress harmful organisms while protecting the soil, plants, and air around them. As the world’s population continues its rapid increase, this book addresses the production of cereals, vegetables, fruits, and other foods and their subsequent demand increase. Traditional means of food crop production face proven limitations and increasing research is turning to alternative means of crop growth and protection. Addresses environmentally focused pest control with specific attention to its role in food security and sustainability. Includes a range of pest management methods, from natural enemies to biomolecules. Written by experts with extensive real-world experience.

Download or read book Parasites and Pathogens of Insects written by Nancy E. Beckage and published by Academic Press. This book was released on 2012-12-02 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both volumes of Parasites and Pathogens of Insects provide in-depth coverage of the interface between insect parasites and pathogens and hosts, and explore the relationships between these partners. They emphasize biochemical and molecular interactions, basic biology, and the roles of hormones, receptors, and other cellular components in modulating interactions between host insects and attacking agents. These topics also are assessed in relation to biotechnology and biological control. In the short term, these volumes fill a void in current literature by emphasizing basic interactions at the biochemical and molecular levels. In the long term, these interactions may provide avenues for exploitation to enhance the rate of "beneficial" parasitism or to reduce the rates of disease transmission and infection of vertebrate hosts. Presents the latest information on insect parasites and pathogens Describes biochemical and molecular host-parasite and host-pathogen relationships Covers mechanisms of insect pathogenicity and resistance Provides exceptional breadth of coverage and authoritative reviews Special topics Transposable elements in insect pathogens Co-evolution and gene transfer between hosts and invaders Biological control
