Increasing crop biodiversity, such as by adjacent managed crops, is recognized an effective biological control measure. However, few studies have focused on the mechanisms involved in how crops increase natural enemy populations, leading to reduced pest numbers. This study investigated hypothesis that cotton grown sorghum would positively influence feeding and oviposition preferences of ladybug...

Gossypol is a naturally occurring compound in the cotton plant (Gossypium spp .) . Because gossypol has been recognized since the turn of the century to be toxic to animals, a limiting factor o f whole cottonseed and cottonseed meal as feed sources is their gossypol content (1) . Whole cottonseed and cottonseed meal are popular by-products of the cottonseed industry . Whole cottonseed is a good...

Methods: For this purpose, animals like rat and soil organisms like Earthworm were selected. Rats were selected on the basis of its 95% homology on genomic, cellular and enzymatic level with human while earthworm were preferred on the basis of their direct contact with soil to evaluate the impact of Bt (Cry1AC) crop field soil on earthworm, secreted by root exudates of Bt cotton. Several physic...

Geocoris punctipes (Say) and Orius insidiosus (Say) are generalist predators found in a wide range of crops, including cotton (Gossypium hirsutum L.) and maize (Zea mays L.), where they provide important biological control services by feeding on an array of pests, including eggs and small larvae of caterpillars. A high percentage of cotton and maize in the United States and several other countr...

No other feed ingredient provides the combination of effective fiber, energy, and protein like whole cottonseed (WCS). These characteristics make WCS an attractive ingredient for including in rations fed to lactating dairy cows that require high concentrations of energy and adequate effective fiber. But like most ingredients, the composition of WCS has changed. The 2002 cotton crop was negative...

Geocoris punctipes (Say) and Orius insidiosus (Say) are generalist predators found in awide range of crops, including cotton (GossypiumhirsutumL.) andmaize (ZeamaysL.), where they provide important biological control services by feeding on an array of pests, including eggs and small larvae of caterpillars.

The feeding and oviposition activity of overwintering boll weevils, Anthonomus grandis grandis (Boheman), and seasonal fluctuations in development, survival, and reproduction of progeny of overwintering and first- and second-generation boll weevil females were determined in the laboratory at 27 degrees C, 65% RH, and a photoperiod of 12:12 (L:D) h. During the cotton-free period in the Lower Rio...

Background : Propionic and butyric acids are important nutrients for the mucosal cells and may therefore increase the nutritional status and reduce the permeability of the colonic mucosa. These acids have also been suggested to counteract diseases in the colon, e.g. ulcerative colitis and colon cancer. Different substrates lead to different amounts and patterns of carboxylic acids (CAs). Object...
