摘　　要：采用浸叶法测定了噻虫胺、高效氯氟氰菊酯等7种药剂及其混用对黄曲条跳甲的毒力及增效作用。结果显示:7种药剂中噻虫胺对黄曲条跳甲的毒力最高,LC50值为315.1 mg/L,其毒力倍数是呋虫胺的3.23倍;其次为噻虫嗪和高效氯氟氰菊酯,LC50值分别为473.1和543.1 mg/L。噻虫胺与高效氯氟氰菊酯按5∶5、4∶6、3∶7、2∶8和1∶9的质量比混用,其LC50值分别是215.6、307.1、334.1、232.6和240.7 mg/L,均表现为增效作用,其中2∶8和1∶9混用的共毒系数分别达203.9和210.5,增效最显著;噻虫胺与丁烯氟虫腈按5∶5、4∶6、3∶7、2∶8和1∶9的比例混用,其LC50值分别为409.2、356.9、338.1、402.4和392.6 mg/L,除5∶5混用表现为相加作用外,其余配比均表现为增效作用,其中1∶9混用共毒系数为182.1,增效显著;噻虫胺与杀虫单按5∶5、4∶6、3∶7、2∶8和1∶9的比例混用,其LC50值分别为479.4、540.0、454.8、737.0和878.7 mg/L,其中3∶7混用的共毒系数为127.9,有明显的增效作用,其余配比均表现为相加作用。噻虫胺与高效氯氟氰菊酯、丁烯氟虫腈、杀虫单混用增效作用明显,可以作为防治黄曲条跳甲的高效药剂。The toxicity and synergistic effects of seven insecticides and their mixtures to Phyllotreta striolata were tested by leaf-dipping method. The results showed that the toxicity of clothianidin was the highest, with LC50 value of 315. 1 mg/L, and the toxicity ratio was 3. 23-fold higher than that of dinotefuran. Thiamethoxam and lambda-cyhalothrin also had high toxicity to P. striolata, with LC50 values of 473. 1 and 543. 1 mg/L, respectively. The mixtures of clothianidin and lambda-cyhalothrin with ratios of 5∶5, 4∶6, 3∶7, 2∶8, 1∶9 showed synergistic effects on P. striolata, with LC50 values of 215. 6, 307. 1, 334. 1, 232. 6, 240. 7 mg/L, respectively, among which the 2∶8 and 1∶9 group showed the highest synergism, with co-toxicity coefficient of 203. 9 and 210. 5 respectively. Clothianidin and butene-fipronil mixed at the ratios of 5∶5, 4∶6, 3∶7, 2∶8 and 1∶9 exhibited LC50 values of 409. 2, 356. 9, 338. 1, 402. 4 and 392. 6 mg/L, respectively, indicating most groups showed synergism against P. striolata except that of 5∶5, and among which the 1∶9 group showed the highest synergistic effect, with co-toxicity coefficient of 182. 1. When the mixed ratios of clothianidin and monosultap were 5∶5, 4∶6, 3∶7, 2∶8, 1∶9, the LC50 values were 479. 4, 540. 0, 454. 8, 737. 0, 878. 7 mg/L, respectively; the mixture at ratio of 3∶ 7 showed synergism effect, with co-toxicity coefficient of 127. 9, while others showed additive effects. The mixtures of clothianidin and lambda-cyhalothrin, butene-fipronil and monosultap, respectively, showed high synergism against P. striolata, suggesting they could be used to control the pest.
