In business analysis, PEST analysis (political, economic, social and technological) is a framework of external macro-environmental factors used in strategic management and market research. PEST analysis was developed in 1967 by Francis Aguilar as an environmental scanning framework for businesses to understand the external conditions and ...
In a pest risk analysis initiated by a specific pathway, often an imported commodity or goods associated with an imported commodity, e.g. packing materials, the probability of pest entry is evaluated for that specific pathway. For a pest risk analysis initiated for a specific pest, all probable pathways are evaluated for that individual pest.
Grain silos in Australia. Grains may be lost in the pre-harvest, harvest, and post-harvest stages. Pre-harvest losses occur before the process of harvesting begins, and may be due to insects, weeds, and rusts. Harvest losses occur between the beginning and completion of harvesting, and are primarily caused by losses due to shattering.
A storage pest is an insect or other animal that damages or destroys stored food or other valuable organic matter. [1] Insects make up a large proportion of storage pests, with each type of crop having specific insects that gravitate towards them.
The wheat weevil (Sitophilus granarius), also known as the grain weevil or granary weevil, is an insect that feeds on cereal grains, and is a common pest in many places. It can cause significant damage to harvested stored grains and may drastically decrease crop yields. The females lay many eggs and the larvae eat the inside of the grain kernels.
Grain damage is any degradation in the quality of grain. In the current grain trade , this damage can affect price, feed quality, food product quality, and susceptibility to pest contamination. Between the field and the end use, grain may go through any number of handling operations which can each contribute to grain damage.
With the falling number test, so-called weather- or sprout-damaged wheat or rye, which adversely affects bread-making quality, could be detected at the grain silo intake within a few minutes. Sprouting, or pre-harvest germination, is caused by damp or rainy weather conditions during the final stage of maturation of the crop.
The flour mite, Acarus siro, a pest of stored grains and animal feedstuffs, [1] [2] is one of many species of grain and flour mites. [3] An older name for the species is Tyroglyphus farinae. [4] The flour mite, which is pale greyish white in colour with pink legs, is the most common species of mite in foodstuffs. The males are from 0.33–0.43 ...
