Rice (Oryza staiva L.) is one of the world's most important crops, providing a stable food for nearly half of the global population (FAO 2004). Almost 90% of the rice is growing and consumed in Asia. The striped stem borer (Chilo suppressalis Walker) is one of the most important rice pests in Asia. Rice stem borers cause damage to the crop at the larval stages. Larvae borer in to the plant stem...

A multi-spectral imaging system for use on agricultural aircraft was developed and tested to provide images of fields and help farmers and crop consultants manage agricultural lands. The results of this research indicate that the airborne MS4100 multi-spectral imaging system has a great potential for use in areawide pest management systems, such as weed control or detection of insect damage. Mu...

Plants are not capable of running away from their enemies, i.e., the herbivores that may eat them. However, under certain circumstances, plants can rely on the natural enemies of insect herbivores for protection. These natural enemies include other insects that are predators and parasitoids. To help protect plants from damage caused by insect herbivores, practical methods have been developed an...

Tajikistan is a hotspot of plant and animal species diversity and endemism andis important for the conservation of biodiversity on a global scale. The country is located ata biological crossroads. Species from Central and Northern Europe, Central Asia, theMiddle East, and North Africa mingle here with endemics found nowhere else. Therichness of Tajikistan‘s biodiversity shows up at the genetic,...

In five field–scale insecticide trials, the repeated application of the synthetic pyrethroid alphacypermethrin to carry-over cane, reduced damage caused by the sugarcane borer Eldana saccharina Walker (Lepidoptera: Pyralidae) to the crop. The insecticide was applied with mistblowers at a rate of 200 ml formulation/ha in 350 L water/ha, once every two weeks for 16 weeks, commencing when the crop...

Wheat (Triticum aestivum) is one of the most important staple food crops, cultivated worldwide. The increased human population would require a major augment in the food supply in coming decades. Extension of sowing fields has only a little possibility; therefore, an increase the crop productivity has become a crucial necessity to assure the future food security [1,2]. Increased use of fertilize...

Insects cause heavy damage to cultivated crop plants. Production of proteinaceous inhibitors that interfere with the digestive biochemistry of insect pests is one of the naturally occurring defence mechanisms in plants. These proteins include lectins, arcelins and inhibitors of alpha amylases and proteases of various larvae pests. Use of plant genes encoding effective inhibitors of major digest...

sowing and harvesting date are the most important agronomic factors that we should pay attention to proper date selection for sowing date in order to achieve good crop establishment and to harvest date in order to achieve the best time for crop quantities and qualities ripening. farmers intend to germinate sugar beet seed at minimum environmental temperature. sowing date affects crop canopy dev...

The use of biochemical or morphological genetic traits in a crop to protect ripening seeds or grain from bird damage remains a promising tool under certain situations. Research on bird-resistance in crops has focused on grain sorghum, corn, sunflower and rice. This crop protection method involves feeding behavior of granivorous birds and its effectiveness depends on the availability of preferre...

T United States contains one of the most important crop production areas in the world. According to the most recent national agricultural census, 1.8 billion bushels of wheat, 10.5 billion bushels of maize, and a wide range of other crops were produced in 2006 from 126 million hectares (315 million acres) in the conterminous United States (USDA NASS 2007). However, owing to the concentrated nat...
