摘　　要：为明确贵州遵义烟区烟田主要害虫的发生规律,筛选出适宜配方的糖醋液诱源有效诱杀烟田害虫,于2017年4月17日至8月15日利用5种糖醋液配方诱源在贵州遵义烟区进行烟田害虫诱杀试验。结果表明,烟田小地老虎、烟青虫/棉铃虫分别在6月上旬、5月上旬出现发蛾高峰期;其他蛾类昆虫在6月上旬和7月上旬出现2个高峰期;中华弧丽金龟成虫在5月下旬至6月上旬和7月上旬出现两个高峰期。糖醋液诱源对天敌昆虫的伤害较小,但在烟株现蕾后对蜜蜂的伤害较大。5种糖醋液配方中,配方Ⅰ(糖:醋:酒:水=6∶3∶1∶10)的诱杀效果最佳,且对蜜蜂伤害相对较小。在贵州遵义烟区烟草成熟期放置糖醋液诱捕器的区域烟草叶片被取食率显著高于未放置诱捕器的区域。To clarify the occurrence of major tobacco pests in Zunyi tobacco fields and select a suitable formula using sugar-acetic acid mixtures,five formulas of sugar-acetic acid mixtures were used to trap and kill tobacco pests in Zunyi tobacco-growing area from April 17 to August 15 in 2017.The results showed that the occurrence of adult Agrotis ipsilon and Helicoverpa assulta/Helicoverpa armigera peaked in early June and early May respectively,and other moths had two obvious peaks in early June and early July.The peaks of Popillia quadriguttata adults appeared in late May to early June and in early July.The sugar-acetic acid mixtures caused little harm to natural insect enemies,but was more harmful to bees after tobacco budding.Among the five formulas of sugar-acetic acid mixtures,the formulaⅠ(sugar∶vinegar∶ethanol∶water=6∶3∶1∶10)had the best trapping and killing effect.Its harm on bees was relatively smaller.The results also indicated that the pest-eaten rate of tobacco leaves in the experimental areas was significantly higher than that in the control areas at the mature stage of tobacco.
