This paper reports on the results of spraying with suspensions of pirimiphos-methyl (2g/m2) and decamethrin (50mg/m2) in experimental huts fixed with window-trapsduring July-October 1982 in the Tangkou People's Commune, Jining County. The results showed that pirimiphos-methyl could effect 50% mortality 'of intrusive A. sl-nensis mosquitos for more than 41 days after spraying, while decamethrin could maintain 50% mortality for two months and more.

This paper reports on the results of spraying with suspensions of pirimiphos-methyl (2g/m2) and decamethrin (50mg/m2) in experimental huts fixed with window-trapsduring July-October 1982 in the Tangkou People's Commune, Jining County. The results showed that pirimiphos-methyl could effect 50% mortality 'of intrusive A. sl-nensis mosquitos for more than 41 days after spraying, while decamethrin could maintain 50% mortality for two months and more. The residual effectiveness of pirimiphos-methyl on walls could last 24-54 days after spraying and its fumigation activity up to 30 days. The residual effectiveness of decamethrin on most kinds of walls could last more than three months, but it had no fumigation activity. For pirimiphosmethyl no evident repellency was noticed, while for decamethrin an enhanced irritability was found. Both insecticides are safe for use and worth further testing ih field application.

1982年7~10月于济宁唐口公社应用甲嘧硫磷水悬剂(2g/m~2)及溴氰菊酯水悬剂(50mg/m~2)于实验小屋进行喷洒。甲嘧硫磷喷洒后对侵入的中华按蚊杀灭效果保持50%以上死亡率达41天以上;溴氰菊酯可达2个月以上。甲嘧硫磷喷洒后墙面持效24~54天,而熏杀作用可达30天;溴氰菊酯于多数墙面持效在3个月以上,但无熏杀作用。甲嘧硫磷无明显兴奋驱避作用;溴氰菊酯有兴奋度增高现象。两药喷洒均较安全,可进行现场试用。

Toxaphene, an organic chloride insecticide possesses a long residual period. This study was composed of dominant lethal test, Salmonella mutagenieity test(Ames test)and DNA synthesis inhibition test. The results of dominant lethal test showed no statistical difference in the number of living, dead and resorbed fetuses between the exposed and the negative control groups. But the rates of encephaloceles in the groups exposed to 3. 12 and 50 mg/kg were higher than those of the control groups. The Salmonella...

Toxaphene, an organic chloride insecticide possesses a long residual period. This study was composed of dominant lethal test, Salmonella mutagenieity test(Ames test)and DNA synthesis inhibition test. The results of dominant lethal test showed no statistical difference in the number of living, dead and resorbed fetuses between the exposed and the negative control groups. But the rates of encephaloceles in the groups exposed to 3. 12 and 50 mg/kg were higher than those of the control groups. The Salmonella mutagenieity test showed that the revertants of TA100 in non-activated incorporation test exhibited positive result in 800 mg/plate, and in the above dosage group a dose-response relationship was observed. Toxaphene inhibited DNA synthesis in mice of the 25mg/kg(1/4 LD 50)group. These results have illustrated the potential mutagenicity of toxaphene.

毒杀芬为有机氯杀虫剂的一种,残效期长。本文通过显性致死试验,沙门氏茵诱变试验和DNA合成抑制试验对该品的诱变作用进行观察。显性致死实验结果表明各剂量组的受孕率、死胎和吸收胎数经统计学处理与阴性对照组无差异。仅胎鼠脑膨出在3.12(1/32LD_(50))与50(1/2LD_(50))mg/kg组的出现率明显大于阴性对照组。沙门氏菌诱变试验结果表明TA100菌株在不加S9条件下对毒杀芬800mg/皿及其以上剂量呈阳性反应。DNA合成抑制试验在毒杀芬25mg/Kg(1/4LD_(50))剂量对小鼠DNA合成有明显抑制作用,从上述三种诱变试验结果来看作者认为毒杀芬具有潜在性的诱变作用。

During the period 1983-1985, a field trial of sandfly control was carried out in a rural endemic kala-azar area near Kashkar, Xinjiang, where Phi. chinesis longi-ductus was the predominant species of sandflies. Wettable powder of K-Othrine was sprayed on the wall surfaces in dosages of 37.5mg, 25mg, and 12.5mg per m2. The residual activity persisted at least 50 days after spraying. In treated villages the population densities of sandflies decreased by 13-19 times than the control village and further decreased...

During the period 1983-1985, a field trial of sandfly control was carried out in a rural endemic kala-azar area near Kashkar, Xinjiang, where Phi. chinesis longi-ductus was the predominant species of sandflies. Wettable powder of K-Othrine was sprayed on the wall surfaces in dosages of 37.5mg, 25mg, and 12.5mg per m2. The residual activity persisted at least 50 days after spraying. In treated villages the population densities of sandflies decreased by 13-19 times than the control village and further decreased in next year, two years later, however, they increased markedly. The efficacy of l-(3, 4-dichlorophenyl)-2. 2, 2-trichloroethyl acetate (la boratory code 7504) a new synthesized insecticide, in dosage of lg/m2 was similar to the lowest dosage of K-Othrine. K-Othrine in the dosage of 12.5mg/m2 for one spraying per two years is recommended as a vector control programme for kala-azar eradication.

用2.5%可湿性溴氰菊酯和国产三氯杀虫酯(7504)进行现场喷洒灭蛉结果表明,每平方米墙面使用溴氰菊酯37.5mg、25mg和12.5mg剂量,可使白蛉数量比对照区降低13—19倍,削平季节高峰。当年的灭蛉效果超过50%的可湿性DDT。在模拟土墙和泸纸药膜上,残效至少可达50天以上。建议以每平方米12.5mg作为灭蛉喷洒剂量推广使用;7504每平方米1g的剂量可使白蛉数量降低8.9倍,值得进一步试用,但其剂型应研究改进。连续观察证明,在当地条件下,于喷洒后第三年白蛉密度可恢复到具有流行病学意义的程度。
