Insect and Disease Pests of Southern Hardwoods
In natural stands, trunk borers are economically the most serious insect pests. The larvae construct galleries in the trunks of living trees, causing the greatest damage in the lower portion (Beal 1952; Hay and Wootten 1955). The quality of the butt log, which is potentially the most valuable portion of the tree, is greatly reduced. Oaks suffer more damage than other hardwoods in the South (Hay...
متن کاملInsect defence: its impact on microbial control of insect pests
Insects are the earliest and most diverse taxon of animals accounting for more species than all other animals put together because of their high reproductive potential and varied niche. Though cellular reactions like phagocytosis, nodulation and encapsulation and humoral reaction through secretion of antibacterial proteins are known for fungus and bacterial invaders, little is known about insec...

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 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...
