目前,谷蠹在储藏稻谷的仓内发展很快,给粮食保管工作带来了一定的威协。由于谷蠹具有耐高温,并喜聚居在粮堆高温部位活动,如保护人员在检查粮情时稍加疏忽,随时都能造成粮食局部发热霉变。所以防治谷蠹,其措施务求周密。否则,由于粮堆内热气流的作用,采用一般的上层熏蒸是不能使谷蠹致死的。粮堆高温部位的害虫都可能由昏迷状态复活而继续危害粮食。散装粮堆局部熏杀谷蠹是我省湘乡县直属粮库创造的一种办法,对当前巩固“四无粮仓”成果是项重要的补助措施,现介绍如下: 在粮堆中,如果发现某局部高温点,可立即用吸式扦样器检查,无吸式扦样器,可扒开粮堆至80~100厘米的深处进行检查,是不是害虫特别是谷蠹聚居活动所致,如果证实是害虫
At present, the valley beetle in the storage of rice in the rapid development of the warehouse, to the food storage work has brought some Wei Association. Due to the high temperature of Trichih pubescens, and Hi living in the high temperature parts of the activities of the grain, such as protection of personnel in the inspection of grain conditions a little negligence, at any time can cause local mildew food mold. Therefore, prevention and control of moth beetle, its measures to ensure thorough. Otherwise, due to the effect of the hot air flow in the grain piles, the use of a general upper fumigation does not kill the gourd. Pests in high temperature parts of the piles may continue to harm food due to the resurgence of coma. The local smothering of grain mines in bulk grain piles is a method created by grain farms directly under the Xiangxiang County in our province and is an important subsidy to the current achievements of consolidating the “no-no-grain silos”. The introduction is as follows: In the grain piles, if found Some local hot spots, can immediately use the suction sampler check, non-suction sampler, can be paved grain heap to 80 ~ 100 cm depth inspection, is not caused by pests, especially the beetles living activities, If confirmed to be pests
