消灭营区蚊蝇,必须以控制孳生地为主,控制孳生地与捕杀成虫相结合,才能使它们灭子绝孙。在控制孳生地方面,除了用清除的方法外(如清除垃圾、填平积水……等),实际上还有许多地方不能采取清除手段,如厕所、化粪池、下水道、稻田……等,就必须采取药物控制。但是上级发的杀虫剂有限,不能坚持多久。七月初浙江日报刊登了余杭县红旗社的农民发现和总结了数十种野生植物,对杀灭农作物害虫有效,并认为对除四害也有价值。结合其它地方一些用野生植物杀蛆的报导,我们觉得这是一个很好的办法,随即派人到余杭县学习。回来对各师进行了讲授,组织了上山刨药的实习,井将其中对孑孓、蛆等有效的百部草、山火筒、闹洋花、青藤树、黄柴树根、滴水龙、山曼头、野巴豆、练蓼草、蟹物树、红藤、烟茎、四叶树、溪沟树、花果树、苦楝树等16种药草编印成册发给部队 Eradication of mosquitoes in camps must be dominated by breeding grounds, and control of breeding places should be combined with the killing of adult beetles so that they will not be destroyed. There are actually many places beyond the means of removal such as toilets, septic tanks, sewers, paddy fields, etc., other than by means of cleaning up (eg rubbish removal, filling of stagnant water ...) , You must take drug control. However, superior pesticides are limited, can not persist for how long. In early July, Zhejiang Daily published the farmers of Hongqi Society in Yuhang County to find and summarize dozens of wild plants, which are effective in killing pests of crops and are of value to the four pests. Combined with the reports of some wild plants kill maggots elsewhere, we think this is a good way to send people to Yuhang County for study. Came back to teach each division, organized the practice of Shanghaishaoyao, and wells which will be larvae, maggots and other effective Baibucao, mountain fire tube, ocean flower, ivy tree, yellow wood root, drip dragon, mountain Cayman , Wild croton, practice Polygonum, crab tree, red cane, tobacco stems, four-leaf tree, ditch tree, flower tree, neem tree 16 kinds of herbs compiled into a book issued to the army
