Abiotically stressful environment in changing climate is predicted to impact negatively the diversity and abundance of insect-pests; and ultimately the extent of damage caused in economically important agricultural crops. This may affect perilously the agricultural production and the livelihood of farmers especially in tropical and subtropical countries where larger proportion of work force is ...

Rosenberger, Randall S.; Smith, Eric L. 1997. Nonmarket economic impacts of forest insect pests: a literature review. Gen. Tech. Rep. PSW-GTR-164-www. Albany, CA: Pacific Southwest Research Station, Forest Service, U.S. Department of Agriculture; 38 p. This report summarizes the results of research on the nonmarket economic impacts of forest insect pests. The majority of the research reports ar...

The research presented describes how a technology called Controlled Atmosphere Temperature Treatment System (CATTS), can be used as a quarantine treatment against insect pests of apples, pears and sweet cherries. High temperature forced air has not been useful for these temperate fruit because the heat dose required to kill the target insect pests (codling moth and western cherry fruit fly) cau...

Gossypium hirsutum (commercial cooton) is one of the most economically important fibers sources and a commodity crop highly affected by insect pests and pathogens. Several transgenic approaches have been developed to improve cotton resistance to insect pests, through the transgenic expression of different factors, including Cry toxins, proteinase inhibitors, and toxic peptides, among others. In...

Plants naturally emit methanol as volatile organic compound. Methanol is toxic to insect pests; but the quantity produced by most of the plants is not enough to protect them against invading insect pests. In the present study, we demonstrated that the over-expression of pectin methylesterase, derived from Arabidopsis thaliana and Aspergillus niger, in transgenic tobacco plants enhances methanol...

INTRODUCTION World trade in agricultural commodities continues to grow. As agricultural trade expands, it increases the risk of introducing exotic insects into new areas where they may become plant pests. The establishment of new pests can be costly due to increased crop damage, control programs, and quarantine restrictions on trade. Quarantine or phytosanitary treatments such as cold, fumigati...

Cucurbit crops host a range of serious sap-sucking insect pests, including silverleaf whitefly (SLW) and aphids, which potentially represent considerable risk to the Australian horticulture industry. These pests are extremely polyphagous with a wide host range. Chemical control is made difficult due to resistance and pollution, and other side-effects are associated with insecticide use. Consequ...

Many insects compete with us humans for agricultural resources, feed on us, or act as disease vectors. Current control efforts rely mostly on the use of insecticides. The use of chemicals to either repel or kill insect pests is the oldest and most commonly used method of pest control. However, with the massive use of insecticides four major problems have arisen. First, many pests have developed...

The effect of a contplex of several insect and nematode pests on yield of yellow squash (Cucurbita pepo L.) was examined in two field tests in southern Florida. Applications of permethrin for insect control and oxamyl primarily for nematode control plus some insect control were made alone and in combination to achieve differential reduction of various insect and nematode components contributing...

Insect pests have caused noticeable economic losses in agriculture, and the heavy use of insecticide to control pests not only brings the threats of insecticide resistance but also causes the great pollution to foods and the environment. Transgenic plants producing double-stranded RNA (dsRNA) directed against insect genes have been is currently developed for protection against insect pests. In ...
