1970～1973年养蜂研究所研究了若干品种蜜蜂孢子虫病的发展与饲料因素的关系。试验确认蛋白质补充饲料——花粉和奶粉会促使蜜蜂孢子虫孢子数增加,碳水化合物饲料比蛋白质饲料对孢子发育的促进要小得多。获得花粉饲料的蜜蜂中,尤其是灰色高加索山地蜂和意大利蜂的孢子虫孢子数增加最多。在饲料中加进花粉和纯奶粉适当,会增长蜜蜂寿命。只喂糖浆的蜜蜂寿命较短。糖浆中配制纯奶粉浓度过高(超过20％),反而会对蜜蜂寿命起相反的作用,这与乳糖酶增加有关。蛋白质饲料刺激蜜蜂幼虫的发育。除了用纯奶粉浓度过高会
From 1970 to 1973, Apicultural Research Institute studied the relationship between the development of several species of bee pollination and feed factors. Trials confirmed that protein-supplemented feeds - pollen and milk powder - led to an increase in the number of spores of the honeybee pollens, and that carbohydrate diets contributed significantly less to spore development than protein feeds. Among the bees that obtained the pollen feed, the spores of Sporis were the most increased, especially the gray mountainous bees and the Italian bees. Add appropriate pollen and pure milk in the feed, will increase the bee life. Honeybees that only feed syrups have shorter lifespans. Preparation of pure milk syrup concentration is too high (more than 20%), but will play a contrary role in bee life, which is related to increased lactase. Protein feed stimulates the development of bee larvae. In addition to high concentrations of pure milk will be
