通过2009年对大螟性诱剂A、B、C、D 4种诱芯进行的田间筛选试验结果显示,B诱芯诱蛾数量大,蛾峰明显,显著优于其他3种诱芯。2010年至2011年将B诱芯应用于对水稻大螟的测报,结果表明,大螟性诱剂不仅具有较强的诱蛾能力,而且在不同年份诱测的各世代蛾峰明显、清晰。通过剥查预测及田间大螟卵孵实际发生情况调查结果验证,利用性诱剂预测能及时准确地反应当年大螟发生的实际情况,预测结果与田间实际发生情况相吻合。
The results of field experiments on the four kinds of induced attractants A, B, C and D induced by Sesamia inferens in 2009 showed that there were a large number of induced entomogenous moths and significant moth peaks, which were significantly better than the other three kinds of attractant. From 2010 to 2011, the B-core was applied to the report of the rice stem borer. The results showed that the sex-attractant of the rice stem borer had not only strong ability to attract moths but also obvious and distinct moth peaks in different years. The results of the investigation of stripping and the actual occurrence of oviposition in the field showed that the use of lure predictor could reflect the actual situation of the occurrence of the stem borer in time in the current year and the predicted results are consistent with the actual occurrence in the field.
