It is well-known that the broad-bean weevil, Bruchus rufimanus Boheman, is a seriousinsect pest infesting the broad-beans in this country. This weevil can only complete onegeneration each year and overwinters in the adult stage. It has been shown by our ex-periments that adult weevils can be completely controlled by mixing the infested broad-beans with 5 p.p.m. of lindane dust, while such a kind of treatment has failed to kill bothlarvae and pupae in seed beans.

It is well-known that the broad-bean weevil, Bruchus rufimanus Boheman, is a seriousinsect pest infesting the broad-beans in this country. This weevil can only complete onegeneration each year and overwinters in the adult stage. It has been shown by our ex-periments that adult weevils can be completely controlled by mixing the infested broad-beans with 5 p.p.m. of lindane dust, while such a kind of treatment has failed to kill bothlarvae and pupae in seed beans. Complete kill can be obtained when the infested broad-beans are fumigated with phostoxin at a dosage of three grams to 200 catties of beans.It is proposed that bean vines and other rufuse, and infested beans, left both in the fieldand on the sunning ground should be cleaned out, plowed under, converted into manure,or burned in order to destroy many wintering weevils out of doors. During both flower-ing and podding stages of the bean plants, dusting with 1% 666 powder in the field ata dosage of 2.5 catties per mow can give better control. Owing to the broad-bean weevilsprefering only to attack the broad-beans in the vicinity of Wuchang, therefore, broad-beanand pea rotation in this region may be very effective to control these pests, and probablypea weevil, Bruchus pisorum L. It has also been shown that the "javel-green"-coloredbroad-beans of larger size are more or less resistant to the weevil's attack than those"greenish-yellow"-colored varieties of smaller size.

本工作于1962年底开始在武昌华中农学院农场内进行,主要探索药剂防治、田园清洁、轮作方法和选择抗虫品种等途径来防治蚕豆象。初步试验表明:用5ppm灵丹粉拌种防治成虫的效果很好,但对豆粒内的幼虫及蛹的毒杀效果都很小。使用磷化铝熏蒸,每200斤蚕豆用药一片(3克),可杀死全部成虫、幼虫及蛹,且不致影响蚕豆的发芽。室内试验,用1:150的6%可湿性666杀卵,效果可达83.3%;大田喷药以在蚕豆花期和荚期各喷一交1%的666粉的效果最好,可将虫蚀率压低到0.1%。据调查,在收割时田间和晒场以及豆秸上都残留着一些有虫豆,是野外的越冬虫源,必须注意田园清洁。蚕豆象每年发生一代,成虫寿命不超过一年,目前只发现为害蚕豆,且只能在田间新鲜蚕豆上繁殖,故有可能采用轮作方法达到彻底消灭蚕豆象的目的。发现大粒和褐绿色皮的蚕豆品种,比小粒和绿黄色皮的蚕豆品种能抗虫,值得进一步研究。

The first generation adultsemerge in early April. Mating takes place 1--2 days after adult emergence and thefemale soon begins to oviposit. A maximum of 318, and minimum of 35, with anaverage of 94.0--148.6 eggs are deposited. The adult stage lasts 3--12 days (the female 5--12 days); the egg stage, 4--41days; the larval stage, 10--36...

黄翅菜叶蜂为油菜、白菜、萝卜等十字花科植物主要害虫之一。在四川凉山地区一年可发生五个重迭世代,以老熟幼虫在土壤中作蛹茧越冬,越冬成虫四月上旬出现,第一代成虫发生于5月上旬-6月中旬,第二代6月上旬-7月中旬,第三代7月上旬-8月下旬,第四代8月中旬-10月中旬,10月间开始越冬。成虫量与油菜生育期有极密切的关系,子叶期成虫量为80.1-93.0%。成虫有较强的伪死性,雨天、阴天伪死性较强,晴天较弱,成虫雨天不活动产卵。雌虫一般多于雄虫,雌虫为68.4-70.9%。雌虫最多产卵量为318粒,最少为35粒。雌成虫寿命5-12天,雌虫3-9天。卵期4-41天,卵孵化率一般为93.3-100%。幼虫有5龄,幼虫期10-36天,1-3龄幼虫多躲在叶背,不易发觉,老熟幼虫潜入1-11厘米土层内化蛹,前蛹期5-21天,蛹期7-25天。成虫初羽化时在土面爬行数分钟才能飞翔,晴天飞翔力强。耕翻土壤对蛹有一定机械损伤,暴露于土面的蛹在自然阳光下照晒其死亡率很高。 666、DDT对黄翅菜叶蜂幼虫具有极强的毒杀效果。敌百虫较差。

Under the same application condition baits made of rice, with husk, containing 0.005% a. i. of Brodifacoum gave 91.8% control of Rattusrattoides Hodgeson and Bandicota indica Bechstein,while those made of rice without husk gave only 79.6% control. As a comparison, the efficacy of Diphacine-Na 0.2% bait was 96.2% kill.

Under the same application condition baits made of rice, with husk, containing 0.005% a. i. of Brodifacoum gave 91.8% control of Rattusrattoides Hodgeson and Bandicota indica Bechstein,while those made of rice without husk gave only 79.6% control. As a comparison, the efficacy of Diphacine-Na 0.2% bait was 96.2% kill. In-cage tests of Brodifacoum to Rattus rattoides Hodgeson under different conditions showed similar results with those of acute toxicants, but the rats died rather slowly and the dissect autopsy revealed an internal haemorrhage. Rat resistence has not yet developed in this region because Diphacine-Na was used as an first anticoagulant rodenticide. Brodifacoum is recommanded by the author as an candidate rodenticide once resistence appeared.

在毒鼠时机、毒饵布放位置及药物剂量一致的条件下,用不同饵料防治稻田害鼠,O.005%大隆稻谷毒饵灭鼠效果达91.8%,0.005%大隆大米毒饵灭鼠效果为79.6%。0.2%敌鼠钠盐稻谷毒饵灭效则为96.2%。以相同的或不同的大隆剂量、不同饵料、不同加药方法对4组笼养黄毛鼠作1次投毒试验,其结果与急性杀鼠剂1次毒杀效果相同,但试鼠呈慢性死亡过程。剖检症状为内出血。本试区仅初次使用第一代抗凝血剂——敌鼠钠盐,尚未产生抗药性的老鼠种群。大隆杀鼠剂,可作为今后出现“超级老鼠”时的接替品种。
