METHOD FOR ASSESSMENT OF TOXICITY AND NUTRITIONAL VALUE OF FEEDS FOR BEES AND BUMBLEBEES, BEEKEEPING PRODUCTS AND OTHER FOOD PRODUCTS PRODUCED BY ARTIFICIAL MICROCOLONIES OF BUMBLEBEES

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, namely to the evaluation of nutritional value and presence of hazardous impurities in feed for bees and bumblebees and beekeeping products. In the method, a quantitative assessment of the state of artificial microcolonies of bumblebees, receiving feeds with test substrates, is performed. Further, the assessment of nutritional value and content of toxic substances is carried out according to four criteria, namely: speed of development of the microcolony, mortality of bumblebee workers, mortality of larvae and number of broods. Each of the four criteria is assigned 0 to 2 points, depending on the degree of achievement of the optimal indicators, and, then, the points are summed up. And the quality of the substrate is evaluated on the basis of the obtained values, namely: high nutritional value and absence of hazardous impurities correspond to at least 7 points; reduced nutritional value of the substrate or insignificant amount of harmful impurities correspond to from 4 to 6 points, low nutritional value of the substrate or significant amount of harmful impurities correspond to no more than 3 points.;EFFECT: invention provides a method for the comprehensive assessment of nutritional value and presence of hazardous impurities in feed using quantitative criteria.;1 cl, 1 dwg, 1 ex, 1 tbl
