Introduction The term pest includes pathogens, weeds, nematodes, mollusks, arthropods, and vertebrates. One category of pests does not occur in the absence of pests in other categories, yet most IPM systems are designed around a single category of pest. For full implementation of IPM it is essential that all categories of pests be managed in an integrated manner. Allowances for the interactions...

Transgenic cotton that produced one or more insecticidal proteins of Bacillus thuringiensis (Bt) was planted on over 15 million hectares in 11 countries in 2009 and has contributed to a reduction of over 140 million kilograms of insecticide active ingredient between 1996 and 2008. As a highly selective form of host plant resistance, Bt cotton effectively controls a number of key lepidopteran pe...

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...

In this paper, we consider a SI system with spraying microbial pesticide and releasing the infected pests, the infected pests have the function similar to the microbial pesticide and can infect the healthy pests, further weaken or disable their prey function till death. By applying the Floquet theorem of linear periodic impulsive equations and the comparison theorem, we show that there exists a...

The aim of this study was to establish the warning and prediction system for crop diseases and pests based on SuperMap IS. NET geographic information system (GIS), which was developed by Supermap company. In this system, the author used GIS and remote sensing (RS) technology. The system could transform data information into a geographical information map to show the occurrence degree and distri...

Intercropping is one of the important cultural practices in pest management and is based on the principle of reducing insect pests by increasing the diversity of an ecosystem. On-farm experiments were conducted in villages of semi-arid tropical (SAT) India to identify the appropriate combination of castor (Ricinus communis L.) (Malpighiales: Euphorbiaceae) and intercropping in relation to pest ...
