| 中文摘要: |
| 甘蔗螟虫是现阶段甘蔗种植过程中最主要的害虫，为了探究吡虫啉、噻虫嗪和噻虫胺等3 种新
烟碱类杀虫剂颗粒剂对甘蔗螟虫的防治效果，采用玻片浸渍法和沟施法测定3 种药剂对甘蔗螟虫的室内毒
力和田间防效。室内毒力测定结果显示：3 种颗粒剂对螟虫都有很好的活性，吡虫啉、噻虫嗪和噻虫胺对条
螟的LC50 值分别为0.3239、0.2003、0.1056 μg/mL，对照药剂克百威的LC50 值为0.1477 μg/mL，噻虫胺对
甘蔗条螟的生物活性高于克百威。2 年2 地田间药效试验结果表明：药后45 d，3 种新烟碱类杀虫剂对甘蔗
螟虫的防治效果均好于呋喃丹，噻虫胺的防治效果好于吡虫啉和噻虫嗪，噻虫嗪略好于吡虫啉，防治效果
与施用剂量正相关。 |
| 英文摘要: |
| Sugarcane borer is the most important pest in sugarcane planting at present. To study the control
effects of 3 neonicotinoid insecticides granules（ imidacloprid，thiamethoxam and clothianidin），their toxicity and
field efficacy were determined by slide dip method and furrow application，respectively. The toxicity determination
showed that three kinds of granules all had good lethal activity for borer and LC50 values of imidacloprid，
thiamethoxam and clothianidin were 0.3239，0.2003，0.1056 μg/mL. The field trials also showed that the control
efficacy of imidacloprid after 45 d，the field efficacy was in an order of clothianidin > thiamethoxam> imidacloprid>
carbofuran，the control effect was positively related to application dose. |
