Predaceous Coccinellidae in biological control.
Coccinellids have been widely used in biological control for over a century, and the methods for using these predators have remained virtually unchanged. The causes for the relatively low rates of establishment of coccinellids in importation biological control have not been examined for most species. Augmentative releases of several coccinellid species are well documented and effective; however...
متن کاملBIOLOGICAL CONTROL Seasonal Abundance of Spider Mites and Their Predators on Red Raspberry in Quebec, Canada
Seasonal abundance of spider mites and their predators on red raspberry was studied in 1993 and 1994 at 2 agricultural locations near Quebec City, Canada. Three raspberry systems, wild raspberry, pesticide-free cultivated raspberry, and commercial raspberry treated with a variety of pesticides, were sampled at frequent intervals. Tetranychus mcdanieli McGregor accounted for 87.5, 80.6, and 95.0...
متن کاملMites as biological tags of their hosts.
Movements and spatial distribution of host populations are expected to shape the genetic structure of their parasite populations. Comparing the genetic patterns of both interacting species may improve our understanding of their evolutionary history. Moreover, genetic analyses of parasites with horizontal transmission may serve as indicators of historical events or current demographic processes ...
متن کاملBiological Control: Insect Pathogens, Parasitoids, and Predators
Stored product insects cause millions of dollars per year in losses in stored wheat. Traditionally, storedproduct pest management has relied on chemicals to control insects. In some cases, pest management has been improved by applying chemicals only when needed. An increasing effort is being made to reduce or eliminate pesticide residues in the food supply. This trend has increased since the in...
متن کاملOverview of the Role of Generalist Predators in Biological Control
Some experiments indicate the ability of coccinellids to significantly suppress aphid abundance. Exclusion of predators by caging aphid-infested plants has repeatedly resulted in higher aphid populations and greater aphid population growth rates. However, aphidophagous coccinellids have never proved effective in controlling aphid populations in the field. To resolve this apparent contradiction,...
