The recently developed synthetic pyrethroid insecticides ( fenvalerate, decamethrin ) have been selected in several tests for the control of Setora Postornata in the peach orchard in the suburbs of Hangzhou from 1980 to 1982. Spraying with these two synthetic pyrethroids was found to be very effective in controlling the larvae of the 1st and 2nd generations. The effective concentration of fenvalerate was 50 to 100 ppm and of decamethrin 5 to 10 ppm. The period of the residual effect lasted at least for...

S5602 and S5439 are two pyrethroid insecticides. It is proved that they are more efficient than other insecticides and less toxic to man and domestic animals. In order to make an overall evaluation of their safe property we carried on some experiments to test whether they can cause any chromosomal aberration or not. The material used is mouse bone-marrow cells. Experimental result shows that when the dose of S5602 or S5439 administra- ted to the mouse was smaller than 1/10 LD50, the percentage of...

S5602 and S5439 are two pyrethroid insecticides. It is proved that they are more efficient than other insecticides and less toxic to man and domestic animals. In order to make an overall evaluation of their safe property we carried on some experiments to test whether they can cause any chromosomal aberration or not. The material used is mouse bone-marrow cells. Experimental result shows that when the dose of S5602 or S5439 administra- ted to the mouse was smaller than 1/10 LD50, the percentage of chromosomal aberrations in mouse bone-marrow cells were low (0. 57%--0. 67%). There is no significant difference when compared with the control (0. 33%). So far as the genetic effect is concerned, it confirms that S5602 and S5439 are exactly agricultural insecticides which are less toxic.

中西杀灭菊酯(S5602)和中西除虫菊酯(S5439)是上海第14制药厂试产的两种拟除虫菊酯类新型杀虫剂。它具有杀虫谱广、用量小、对人畜毒性低等优点。为了全面评价农药中西杀灭菊酯和中西除虫菊酯的安全性,我们进行了小白鼠骨髓细胞染色体的畸变试验。试验结果表明,小白鼠的给药剂量在1/10LD50以下,染色体畸变细胞率很低(0.57%~0.67%)和对照组比较无显著差异。这从细胞遗传学效应上证明了中西杀灭菊酯和中西除虫菊酯确是毒性较低的农药。

This paper studied the accumulation and release of the eight intermediates in synthesizing pyrethroid insecticides in goldfish and carp muscle. The experimental results show that degree of accumulating the same compounds between the two kinds of fishes increased with their partition coefficients. There is a linear relationship between log (BCF) (log of the bio-concentration factor) and log P(log of partition coeffecient of the compound) values, in the form of log (BCF) =1.062 log P-1.568, where n = 8 and r = 0.975. The release rate of the eight compounds accumulated in goldfish muscle from waterbody fits in with the first-order reaction kinetics. It also shows that log t1/2(log of biological half life) values are related to log P values. The equation may be written such that log t1'2=0.784 log P-1.571, where n = 8 and r = 0.945.

本文研究了8种与拟除虫菊酯合成有关的化合物在金鱼和鲤鱼肌肉中的积累和释放行为.实验结果表明,不同鱼种积累同一化合物的程度不同,其差别随着分配系数的增加而显著增加.平衡时的生物富集因子的对数log(BCF)值与分配系数的对数log P值之间有较好的线性关系,其相关方程式为log(BCF)=1.062 logP-1.558(n=8,r=0.975).化合物从鱼体释放到水中的速度符合一级反应动力学公式.释放半衰期的对数log t_(1/2)值亦与log P值相关.其相关方程式为log t_(1/2)=0.784 log P-1.571(n=8,r=0.945).本文结果有助于预测该类有机污染物对环境的影响.
