除虫脲作为谷物保护剂对贮粮害虫均有效,但谷斑皮蠹例外,因该虫对许多杀虫剂都具有很高的忍耐力。但除虫脲对谷斑皮蠹的生殖力有抑制作用。在35℃,相对湿度80%条件下,用碎麦为食繁殖获得成虫,经1—3天让其在麦粉中产卵,待孵出幼虫后选取3天、7天、14天的幼虫分3组分别以含除虫脲有效成分0.05—12.8毫克的食料喂食,定期检查,计算出生殖力(每雌产生的子代数)。试验表明除虫脲对谷斑皮蠹生殖力的影
Diflubenzuron is effective as a grain protectant on stored grain pests, except for Grifola, which is highly endurable to many insecticides. However, diflubenzuron had inhibitory effects on the fecundity of Porphyra. Under the conditions of 35 ℃ and relative humidity of 80%, the adults were obtained from the breed of breed of cuttlefish and spawned in the wheat flour after 1-3 days. After larvae were hatched, the larvae of three days, seven days and fourteen days were selected The three groups were respectively fed with the food containing 0.05 to 0.8 milligrams of the active ingredient of diflubenzuron and checked regularly to calculate the fecundity (daughter generation per female). Experiments showed that diflubenzuron on Guppy Beetle fecundity shadow
