| 【目的】研究氯虫苯甲酰胺对甘蔗白蚁的田间防治效果。【方法】于 2018 年和 2019 年采用拌肥
料撒施法进行两种不同含量氯虫苯甲酰胺对甘蔗白蚁的田间防治试验。在收获前（11 月）调查甘蔗白蚁为害株，
收获时调查白蚁为害株、甘蔗有效茎数和测定产量，计算甘蔗白蚁防治效果与经济效益。【结果】在板麦村试
验点 5% 氯虫苯甲酰胺 7.5 kg/hm2 和 4% 氯虫苯甲酰胺 7.5 kg/hm2 对甘蔗白蚁为害株率差异不显著，但显著低于
对照药剂 15% 吡虫啉 7.5 kg/ hm2 的白蚁为害株率；而在渠凹村 3 种药剂处理白蚁为害株率差异不显著。总体而言，
以 5% 氯虫苯甲酰胺 7.5 kg/hm2防治甘蔗白蚁效果较好，可将白蚁为害株率控制在 3% 以内，防治效果达 80% 以上；
甘蔗产量比空白对照增加 19.2~31.5 t/hm2
，纯收入增加 8 784~15 180 元 /hm2
，增产增收明显。【结论】5% 氯虫
苯甲酰胺（桂中 2 号）7.5 kg/hm2 对甘蔗白蚁具有良好的防治效果，效益显著，可在甘蔗白蚁为害较严重的蔗区
推广使用。 |

| 【Objective】The study was carried out to understand the field control effect of chlorantraniliprole
against sugarcane termite.【Method】The field control effects of two different doses of chlorantraniliprole applied by
mixed fertilizer broadcasting method on sugarcane termite were studied in 2018-2019. The plants damaged by sugarcane termite were investigated before harvest (in November), the damaged plants and effective sugarcane stems were investigated
and the sugarcane yield was measured when harvested. The control effects on sugarcane termite and the economic benefits
were analyzed.【Result】There was no significant difference in the damaged plant rates of sugarcane termites treated by
chlorantraniliprole 5% with 7.5 kg/hm2
and chlorantraniliprole 4% with 7.5 kg/hm2
, and both significantly lower than that
of sugarcane termite treated by imidacloprid 15% with 7.5 kg/hm2
at Banmai Village test site, while there was no significant
difference in the damaged plant rates of sugarcane termites treated with the three pesticides at Qu'ao Village test site. On the
whole, the control effect of chlorantraniliprole 5% with 7.5 kg/hm2
on sugarcane termite was better. The damaged plant rate of
termite treated by chlorantraniliprole 5% with 7.5 kg/hm2
was under 3%, with the field efficacy of over 80%. Compared with the
control, the sugarcane yield under treatment of chlorantraniliprole 5% with 7.5 kg/hm2
increased to 19.2-31.5 t/hm2
, and the net
income increased to 8 784-15 180 yuan/hm2
, with obvious increases of yield and income. 【Conclusion】Chlorantraniliprole 5%
(Guizhong no.2) with 7.5 kg/hm2
has better control effect on sugarcane termite with significant benefits, which can be used as the
pesticide for controlling sugarcane termite in cane areas where this pest seriously damage. |
