三种杀虫剂防治云斑天牛的林间药效试验

Efficacy of Three Insecticides for the Control of Batocera horsfieldi

摘要:

摘要：本文研究比较了三种杀虫剂防治杨树云斑天牛的试验效果。结果表明，48%噻虫啉悬浮剂、10%高效氯氟氰微囊悬浮剂和8%氯氰菊酯微囊剂对云斑天牛都具有较好的防治效果。药后3天，48%噻虫啉悬浮剂的防效为72.5%～77.5%；8%氯氰菊酯微囊剂的防效为70.0%～72.5%。药后14天，48%噻虫啉悬浮剂的防效为89.9%～96.2%；10%高效氯氟氰微囊悬浮剂防效为73.8%～95.0%；8%氯氰菊酯微囊剂的防效为88.6%～91.1%。因此，这三种杀虫剂均可用于杨树云斑天牛的防治。

Abstracts:The field controlling efficacies of three pesticides on Batocera horsfieldi were determined in the paper. The results showed that the effects of 48% thiacloprid SC, 10% cyhalothrin CS and 8% Cypermethrin CS on control B. horsfieldi were good. After 3 days, the effects of 48% thiacloprid SC were 72.5%～77.5%. And the effects of 8% Cypermethrin CS were 70.0%～72.5%. After 14 days, the effects of 48% thiacloprid SC were 89.9%～96.2%. And the effects of 10.0% cyhalothrin CS were 73.8%～95.0%. And the effects of 8% Cypermethrin CS were 88.6%～91.1%. Therefore, these three insecticides are applicable to controlling B. horsfieldi.
