摘要
采用从加拿大引进的人工合成的缓释性信息化合物诱芯和国产8漏斗式诱捕器,于2005年5月初至7月中旬在辽宁的千山进行了黄色梢小蠹诱捕试验,结果表明,供试的4种信息化合物所配置的3种诱芯组合2AP(2个α-蒎烯诱芯)、2AP+NL(壬醛诱芯)+TV(反式马鞭草烯醇诱芯)、2AP+NL+MT(桃金娘烯醇)+TV平均每天每个诱捕器都能诱到100头左右的黄色梢小蠹,各诱芯组合的效果没有显著差异,其中2AP组合,即2个α-蒎烯诱芯的组合价格成本最低,应该是生产实用的最佳信息化合物诱芯候选;这一结果同时揭示出在引诱黄色梢小蠹的过程中壬醛、反式马鞭草烯醇、桃金娘烯醇这3种成分对α-蒎烯没有增效或抑制作用。
Field trapping of Cryphalus fulvus with semiochemicals was conducted in Qian Mountain Forest from the beginning of May to mid July, 2005. The results showed that the three lures with combinations of four tested semiochemicals(AP(Alpha-α-pinene), 2AP + NL(nonanal) + TV( trans-verbernol), 2AP + NL + MT + TV(myrtenol) imported from Canada) could trap averagely about 100 beetles per day. There were no significant differences among the combinations of the lures. However, the combination of 2AP cost least, so it was the best candidate for control. Meanwhile, the results showed that nonanal(NL) 、trans-verbernol(TV) ,myrtenol(MT) did not had synergistic or inhibition effects on alpha-pinene(AP).
