摘要
在实验室条件下,对八种饲料配方筛选的基础上,以三种饲料配方作了两种湿度条件下粉尘螨种群发展的观察研究.结果表明:粉尘螨种群在25℃时,相对湿度75%比相对湿度80%条件下发展得快,试验配比中的土霉素对粉尘螨有抑制作用,以对羟基苯乙酸酯代替山梨酸可以缩小成螨雌/雄比例.
In laboratory 8 feed formulas were selected. Population development of flour dust mite which feeded 3 feeds was observed at two different relative humidity. The results indicated population development of flour dust mite was faster at 25℃ and 75%r.h. than that at 80r.h..Terramycin of experimented feeds showed inhibition to flour dust mite. It is possible that ethyl-hydroxybenzoate takes the place of sorbic acid to reduce adults proportion of female/male.
