大豆蚜对溴氰菊酯和氯氰菊酯的敏感度研究

Susceptibility of Aphis glycines to decamethrim and cypermethrin

试验测定了敏感品系大豆蚜对2.5%溴氰菊酯乳油和4.5%高效氯氰菊酯乳油的敏感度。结果表明:大豆蚜对两种药剂具有较高的敏感度。接触稀释10 000倍的2.5%的溴氰菊酯乳油和4.5%的高效氯氰菊酯乳油24 h后,大豆蚜的死亡率分别达99.28%和100%。

The susceptibility of Aphis glycines Matsumura to 2.5% of Decamethrim EC and 4.5% of Cypermethrin EC were measured in the experiment. The result shows that A. glycines has the lfigh susceptibility to two pesticides. The moaality of A.glycines is 99.28% ±0.72% and 100% when the pests were treated with 2.5% Decamethrim EC and 4.5% Cypermethrin EC diluted 10 000 times after 24 hours.
