摘要:

为弄清冬季施用药剂防治海南红火蚁能否取得良好的防控效果,对比了0.6%高效氯氰菊酯粉剂与0.08%茚虫威饵剂2种药剂在冬、夏季的防效差异。结果表明:药后时间、季节差异、药剂种类对红火蚁蚁巢的防治效果均影响明显,冬季于药后7~30 d范围,0.6%高效氯氰菊酯粉剂对红火蚁蚁巢的防治效果明显优于0.08%茚虫威饵剂,夏季于药后15~45 d范围,0.08%茚虫威饵剂对红火蚁蚁巢防治效果高于0.6%高效氯氰菊酯粉剂;0.08%茚虫威饵剂冬季对红火蚁蚁巢的防治效果随药后时间增加而上升,药后45 d最高(82.03%),夏季对红火蚁的防治效果15 d达92.49%,与30、45 d无显著差异;0.6%高效氯氰菊酯粉剂对红火蚁蚁巢的防治效果随药后时间的增加而下降,但冬季的下降速度慢于夏季。2种药剂对红火蚁工蚁的防治效果随药后时间的增加而下降;0.08%茚虫威饵剂对工蚁的防治效果除药后7 d外,冬季的防治效果均显著高于夏季;0.6%高效氯氰菊酯粉剂对工蚁的防治效果7~30 d内无明显差异,但在45 d时冬季(97.86%)明显高于夏季(80.57%)。综上,海南冬季天气晴好,且气温在13~21℃时,可选用0.08%茚虫威饵剂或0.6%高效氯氰菊酯粉剂对红火蚁实施防控,防控后防控效果的评价延后至药后30~45 d开展。

Abstract:

In order to find out whether applying insecticides to control Solenopsis invicta in winter can achieve good control effect, this experiment compared the control effects of 0.6% cypermethrin powder and 0.08% indocarb baits in winter and summer. The results showed that the time after treatment, the difference of seasons and the kinds of agents had significant effects on the control effect of the nests of S. invicta. The control effect of 0.6% cypermethrin on the nests of S. invicta was significantly better than 0.08% indocarb in the range of 7-30 d after treatment in winter, and the effect of 0.08% indocarb on the nest of S. invicta was higher than 0.6% cypermethrin in the range of 15-45 d in summer. The effect of 0.08% indocarb baits on the nests of S. invicta in winter increased with the increase of time after treatment, and the highest effect (82.03%) was found at 45 d after treatment. The effect of 0.08% indocarb baits on S. invicta in summer was 92.49% at 15 d after treatment, which had no significant difference compared with 30 d and 45 d. The control effect of 0.6% cypermethrin on the nest of S. invicta decreased with the increase of time after treatment, but the decrease rate was slower in winter than in summer. The control effect of the two agents on the workers of S. invicta decreased with the increase of time after treatment. The control effect of 0.08% indocarb baits on the workers was significantly higher in winter than in summer except 7 d after treatment. The control effect of 0.6% cypermethrin powder on worker ants had no significantly difference within 7 d to 30 d. But at 45 d, it was significantly higher in winter (97.86%) than in summer (80.57%). In conclusion, when the weather in Hainan is fine in winter and the temperature is between 13-21℃, 0.08% Indocarb baits or 0.6% cypermethrin powder can be used to control S. invicta. The evaluation of the control effect is postponed to 30-45 d after treatment.
