Cover crops and control of arthropod pests of agriculture
Cover crops can harbor both harmful and beneficial arthropods (1, 3). Damage to cover crops themselves is rarely of concern; more important is the possibility that pests harbored amid cover crops may disperse to adjoining cash crops [see Kennedy and Margolies (31) for a discussion of the dynamics of such mobile pests]. Here, I explore the roles that cover crops play in the life cycles and popul...
متن کاملThe impact of secondary pests on Bacillus thuringiensis (Bt) crops.
The intensification of agriculture and the development of synthetic insecticides enabled worldwide grain production to more than double in the last third of the 20th century. However, the heavy dependence and, in some cases, overuse of insecticides has been responsible for negative environmental and ecological impacts across the globe, such as a reduction in biodiversity, insect resistance to i...
متن کاملOptimizing Crops for Biocontrol of Pests and Disease.
Volatile compounds and extrafloral nectar are common defenses of wild plants; however, in crops they bear an as-yet underused potential for biological control of pests and diseases. Odor emission and nectar secretion are multigene traits in wild plants, and thus form difficult targets for breeding. Furthermore, domestication has changed the capacity of crops to express these traits. We propose ...
متن کاملBt crops benefit natural enemies to control non-target pests
Crops producing insecticidal crystal (Cry) proteins from Bacillus thuringiensis (Bt) control important lepidopteran pests. However, pests such as aphids not susceptible to Cry proteins may require other integrated pest management (IPM) tactics, including biological control. We fed aphids on Bt and non-Bt plants and analyzed the Bt protein residue in aphids and compared the effects of Bt plants ...
متن کاملApplication of ICT in Pests Control and Diseases Management of Food Crops
This paper proposes a web-based Agro-Information System (AIS) prototype that can support farmers with agricultural-related information about a given food crop. Consistency in the application of this information can help in improving crop yield, in controlling crop pests, in crop diseases treatment, and in enhancing the overall crop productivity. A prototype AIS capable of providing possible pes...
