The co-evolution of pollinators and angiosperms has contributed to the remarkable diversity and success of bees and bee-pollinated plants (Harder & Johnson 2008). Many pollinated plants provide nectar or pollen rewards that encourage foragers to be faithful to the same floral species (Gegear & Burns 2007). These rewards can also lead to site constancy, in which foragers visit the same foraging ...

The beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is an important pest of numerous crops, and it causes economic damage in China. Use of secondary metabolic compounds in plants is an important method used to control this insect as a part of integrated pest management. In this study the growth, development, and food utilization of three successive generations of S. exigua f...

The article provides the description of production experiment carried out at a mill for varietal grinding wheat into baking flour, technological scheme which selection pasta grits. To obtain statistical set data, was organized 10 days, during values studied process parameters were recorded every two hours. output grits chosen as this. These products are subjected to thorough sorption on sieves ...

Daily food intake and corresponding feeding activity (measured as duration) and feeding efficiency (amount of food ingested per unit of feeding activity) were measured both in normal Sprague-Dawley and Buffalo rats and during growth of Walker 256 and 4M mammary carcinomas in Sprague-Dawley rats and of Morris 5123 hepatoma in Buffalo rats. Estimates of meal size and frequency were also obtained....

Differences between elderly subjects (n = 46, 61-86 years) and young subjects (n = 36, 18-25 years) in food perception and food liking were investigated. Intensity and liking ratings were assessed for custard dessert, in which flavor enrichment, textural change, and irritant addition were incorporated as strategies to compensate for sensory losses with increasing age. The sensory acuity (taste,...

In this paper we investigate the economic and environmental efficiency of charities and NGO’s “rescuing” food waste, using a 2008 case study of food rescue organisations in Australia. We quantify the tonnages, costs, and environmental impact of food rescued, and then compare food rescue to other food waste disposal methods composting and landfill. To our knowledge this is the first manuscript t...

The blue mussel, Mytilus edulis, is able to use biochemical cues to sort food particles. Recently, a mucosal lectin (MeML) identified in pallial organs of M. edulis was suggested to play a role in the capture and sorting of food particles. The current study presents data obtained in 2010 showing that sorting efficiencies and MeML gene expression in M. edulis increased when mussels were either f...

Anti-microbial drugs are widely employed for the treatment and cure of diseases in animals, promotion of animal growth, and feed efficiency. However, the scientific literature has indicated the possible presence of antimicrobial drug residues in animal-derived food, making it one of the key public concerns for food safety. Therefore, it is highly desirable to design fast and accurate methodolog...
