2012年在河北省藁城市对二点委夜蛾A、B两种性诱芯的诱蛾效果进行了田间试验研究。试验1即4月25日至5月6日在小麦地的试验结果表明,B诱芯的平均诱蛾量是A诱芯的3.45倍,差异显著。试验2即6月18日至7月25日在玉米地的试验结果表明,在6月18日至7月11日,B诱芯的平均诱蛾量比A诱芯低22.33%,差异未达显著水准;而在7月12～25日,B诱芯的平均诱蛾量是A诱芯的2.71倍,差异极显著。与此类似,B诱芯的单盆日最大诱蛾量达到245头,显著超过A诱芯的74头。可见B诱芯的诱蛾性能具有较大优势。
In 2012, a field experiment was conducted in Xiangcheng, Hebei Province, on the trapping effects of two sexually-transmitted nuclei (A and B). The results of experiment 1, ie from April 25 to May 6 in wheat field, showed that the average amount of induced entrapment in the B-induced motile was 3.45 times that of the A-induced motile, and the difference was significant. Experiment 2, that is, from June 18 to July 25 in the corn field, showed that the average number of induced moth entrapments in B was 22.33% lower than that in A from June 18 to July 11, and the difference was not reached Significant level. On July 12 ~ 25, the average number of induced moths induced by B was 2.71 times that of the A-induced ones, the difference was significant. Similarly, the maximum number of induced moths per single pot in the B-trap was 245, which was significantly higher than 74 in the A-trap. It can be seen that the entrapment properties of the B-core are of great advantage.
