in this study, soymilk curd (tofu) was produced and evaluated at three stages according to iranian preference. in the first stage, the effect of soybean varieties (williams & habbit), production methods (traditional & recommended), and formulation (0, 10 and 20% cheese whey instead of water used in soymilk production) on the qualitative and quantitative characteristics of tofu were evaluated. i...

Acaricide is a pesticide designed to control harmful species of mites (Acari)1. In crop protection practices, acaricides are used against phytophagous mites, pests causing economic injuries to agricultural crops and ornamental plants. Until mid-twentieth century, in agroecosystems of low-level productivity, phytophagous mite populations usually stayed below economic injury levels, due to natura...

Spider mites are considered as a potential threat to varying agricultural crops across the globe. Among agriculturally important spider mite species, Tetranychus urticae Koch and macfarlanei Baker Pritchard severely affect crop production incur heavy yield loss in agriculture sector. As an ecofriendly pest management strategy, biocontrol using phytoseiid predatory gaining significant attention ...

In agricultural applications, the introduction of predators is used to control the prey/pests level so that crop damage is limited; however, though a satisfactory equilibrium between predators and prey may exist, it may be unstable. In order to achieve pest control, its stabilization should then be achieved and, since predator releases occur at discrete time instants, we model them through impu...

Seasonal changes in the diel feeding patterns of the zooplanktivorous icefish (Neosalanx taihuensis), which is an endemic species of China, were studied in the large, shallow eutrophic Lake Chaohu of China during the autumn of 2002 and summer of 2003. The results of the diel feeding rhythm indicate that icefish is a visual particulate feeder. There were large differences in diet composition and...

Large carnivores inhabiting ecosystems with heterogeneously distributed environmental resources with strong seasonal variations frequently employ opportunistic foraging strategies, often typified by seasonal switches in diet. In semi-arid ecosystems, herbivore distribution is generally more homogeneous in the wet season, when surface water is abundant, than in the dry season when only permanent...
