摘要
【目的】为明确不同太阳能光源波长对松墨天牛Monochamus alternatus诱捕效果的影响,并评价太阳能光源与引诱剂联合应用对松墨天牛引诱剂的促进作用,以应用于松墨天牛的绿色防控。【方法】选择波长为365-370、370-375、380-385、390-395、395-400、400-405、405-420、515-520、580-590和600-610nm的10种太阳能LED光源,测定不同光源对松墨天牛的林间诱捕效果,并筛选出诱捕效果最好的光源波长,选择此波长与引诱剂组合对松墨天牛进行诱捕试验。【结果】10种不同波长太阳能光源对松墨天牛均表现出一定的引诱作用,其中波长为380-385nm的太阳能光源对松墨天牛诱捕效果最好,诱捕量为(12.00±6.53)头,其次是390-395 nm,显著优于波长为365-370、370-375、390-395、395-400、400-405、405-420、515-520、580-590和600-610nm;与单独使用引诱剂相比,太阳能光源与引诱剂组合对松墨天牛诱捕效果具有显著的促进作用(P<0.05)。太阳能光源与引诱剂诱捕量均值为(21.83±10.65)头,比单独引诱剂诱捕效果提高35%,为单独太阳能光源诱捕效果的5.9倍;引诱剂诱、太阳能光源和太阳能光源与引诱剂联合应用捕到的松墨天牛雌雄性比分别为2.4∶1、1.7∶1和3.3∶1,均具有显著的偏雌性。【结论】太阳能光源与引诱剂联合应用具有比单独引诱剂诱捕更好的诱捕效果。这一结论对降低松墨天牛种群密度和减少松材线虫病传播几率具有重要意义。
[Objectives]To determine the relative attractiveness of different solar light source wavelengths to Monochamus alternatus,and to evaluate the benefits of using a combination of a solar light source and an attractant.[Methods]The attractiveness of 10 different light wavelengths(365-370、370-375、380-385、390-395、395-400、400-405、405-420、515-520、580-590 and 600-610 nm)to M.alternatus,and that of a combination of a solar light source and an attractant,were quantified and compared.[Results]A wavelength of 380-385 nm was significantly better than all other wavelengths tested for trapping M.alternatus.The combination of a solar light source and F2 attractant captured significantly more M.alternatus(P<0.05),on average,(21.83±10.65)individuals per trap;35%more than the number captured using only attractant and 5.9 times more than when using only a solar light source.In addition,the female-to-male ratio captured by the attractant was 2.4∶1,whereas the female-to-male ratio trapped using a solar light source alone was 1.7∶1.[Conclusion]Using a combination of a solar light source and an attractant trapped significantly more insects than using an attractant alone.This finding can potentially improve the control of M.alternatus,thereby reducing the transmission of pine wood nematode disease.
