A myriad of policy tools (regulations and market Research to develop pesticide alternatives is gaining incentives) could be used to reduce the negative ground as a major focus of USDA’s nonregulatory environmental and health effects of pesticides. The approach for reducing the risks associated with sessions summarized in Part V focused on pesticides, and several sessions in Part V were nonregul...

This review draws together available information on the biology, methods for study, and culturing of hymenopteran parasitoids of the Queensland fruit fly, Bactrocera tryoni, and assesses prospects for improving biological control of this serious pest. Augmentative release of the native and naturalised Australian parasitoids, especially the braconid Diachasmimorpha tryoni, may result in better m...

Many factors including pest natural enemy ratios, starting densities, timings of natural enemy releases, dosages and timings of insecticide applications and instantaneous killing rates of pesticides on both pests and natural enemies can affect the success of IPM control programmes. To address how such factors influence successful pest control, hybrid impulsive pest-natural enemy models with dif...

Neonicotinoid insecticides are widely used for control of insect pests around the world and are especially pervasive in agricultural pest management. There is a growing body of evidence indicating that the broad-scale and prophylactic uses of neonicotinoids pose serious risks of harm to beneficial organisms and their ecological function. This provides the impetus for exploring alternatives to n...

The redlegged earth mite, Halotydeus destructor, continues to be an intractable pest causing damage to most crop and pasture species in southernAustralia.H. destructor feed on all stages of plants, but particularly damage seedlings in autumn. Research has aimed to develop new controls based on a better understanding of the biology and ecology of this pest. Chemicals remain the key tool to contr...

Research into the biology and control of pest birds in Somalia has continued intermittently since 1971 under UNDP funding of four projects. Data have been gathered on the identification, distribution, and status of the principal pest species to agriculture. These species include the Red-billed Quelea (Quelea quelea), of which northern and southern races occur, and several other ploceid weavers ...

Integrated pest management (IPM) is a method of reducing economic, human health, and environmental risks from pests and pest management strategies. There are questions about the long-term success of IPM programs in relation to continued use of pesticides in agriculture. Total pounds of pesticides applied is a mis-measure of the impact of IPM in agriculture. A more complete measurement of the lo...

Each turfgrass species and cultivar has particular optimal growth requirements. Water, fertility and mowing height differ. Similarly, insect pest management needs vary with grass type. As chemical pest management tools become less available, researchers at the University of Georgia are seeking alternative methods in the management of common turfgrass pests. Their foundation management strategy,...
