摘要
2002年5月、6月,在关帝林区西葫芦林场、三道川林场分别进行了红脂大小蠹(Dendroctonusvalens,Leconte)信息素配方、诱杀时间及诱杀效果试验。结果表明:5月中旬到6月中旬为最佳诱杀时期;使用β 蒎烯∶α 蒎烯∶3 蒈烯为1∶1∶1配方的信息素进行大面积诱杀,林木被害率下降64 4%,平均侵入孔数下降59 2%;红脂大小蠹(\%Dendroctonusvalens,Leconte)信息素成份以β 蒎烯∶α 蒎烯∶3 蒈烯为1∶1∶3或全部是3 蒈烯的两种配方为最佳配方;使用信息素诱杀红脂大小蠹(Dendroctonusvalens,Leconte)平均每667m2投资5 5元,省工省时防效好,可大面积推广应用。
Pheromone prescription, trapping period and trapping effect were studied in Xihulu and ShandaoChuan forestfarm of Guandi forestry areas in May, June, 2002.The result showed:the optimum trapping period was from the mid of May to the mid of June; Using Pheromone prescribed by β\|pinene:α\|pinene:3\|carene is 1:1:1 to proceed mass trapping, the ratio of attracted forest decreases by 644 percent, the average number of attracted pore decreases by 592 percent. The optimum prescription was that β\|pinene:α\|pinene:3\|carene is 1∶1∶3 or all are 3\|carene; Each acre was invested 55 Yuan to trap \%Dendroctonus valens,\%Leconte, and it could save labors and time, and have good effect. So Pheromone could be mass popularized.
