摘要
利用引诱剂在保山市宝盖山林场监测华山松木蠹象的种群动态。结果表明:3种引诱剂均对华山松木蠹象有较好的引诱效果,引诱剂B(3-(+)-蒈烯(、+)-柠檬烯和1-甲基-2-异丙烯基-环丁烷乙醇)的诱捕量最多;3种引诱剂诱捕木蠹象总量的自然对数均与样地中虫口密度的线性拟合度较好;引诱剂B诱捕总量的自然对数与样地中有虫株率有较好的线性拟合度。说明监测结果可较好地反映样地中华山松木蠹象的种群密度。
The dynamic change of Pissodes punctatus population was monitored on Baogai Mount Forest Farm of Baoshan Municipality by applying different attractants.The results showed that 3 types of attractants had better trapping effect.Attractant B（3∶ 1∶ 0.002 of（＋）-3-carene,（＋）-limenene and grandisol） trapped the most pest insects.The test of monitoring reliability showed that the natural logarithm of total catches by the 3 types of attractants had pretty good linear relationship with population densities of the plots.There was a good linear relationship between the natural logarithm of total catches by attractant B and the infested ratios.The monitoring results could factually reflect the population densities of Pissodes punctatus in the tested plots.
