This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alfalfa weevil (Hypera postica Gyllenhal) is a pest of alfalfa (Medicago sativa L.). Insecticides are the primary method of weevil control but with increasing insecticide resistance, alternative non-chemical methods are critical for future management. Multiple studies were conducted to explore two alternative methods: early harvest and biological control. Early harvest is a mechanical method of control where recommendations are vague and previous work is insufficient for improving recommendations. One study based in Wyoming and one spanning multiple states in the Intermountain West was conducted to 1) evaluate how early harvest compares to insecticides and 2) impacts both alfalfa weevil populations and their natural enemies. Biocontrol is another promising alternative method of alfalfa weevil control. Bathyplectes curculionis (Thomson) is an imported European parasitoid that is commonly collected in the Intermountain West but does not adequately manage weevils. It remains largely unknown why B. curculionis is not more successful, but they are documented to host both native and introduced hyperparasitoids. Hyperparasitoids potentially impact B. curculionis survivorship, but this remains largely understudied. Through sampling efforts across the Intermountain West, we quantified hyperparasitoid parasitism in the region within alfalfa-alfalfa weevil systems and explored the interaction between B. curculionis and hyperparasitoids. Through our efforts, we determined early harvest is an effective method of weevil control comparable to insecticide use. Multiple hyperparasitoid species were found consistently across the region but their impact on B. curculionis biocontrol remains unclear. This combined early harvest and biocontrol work will support IPM recommendations to growers and increase alfalfa production sustainability.

Download or read book The Alfalfa Weevil and Methods of Controlling it written by and published by . This book was released on 1916 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alfalfa weevil destroys a great deal of alfalfa in northern Utah and southern Idaho. It also inhabit southwestern Wyoming and is spreading slowly to new territory in all directions. I may in time infest most of the United States. The adult, a small brown snout-beetle, and th larva, a green wormlike creature, usually escape notice during the first two or three years that they are present in a locality, but as soon as they begin to become numerous enough to do harm they are readily found, and their effect upon the appearance of the fields is conspicuous. Vigorous treatment is then necessary to prevent partial or total destruction of the first and second crops. The purpose of this bulletin is to show how serious the attack is to the farmer, how much territory it embraces and how it spreads, a nd to describe the insect, its work, and the methods which are effective in dealing with it.

Download or read book Edible Insects written by Arnold van Huis and published by Bright Sparks. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
