十种地膜对华北大黑鳃金龟的物理阻隔效果
Physical barrier efficiency of ten types of mulch to northern China scarab beetle Holotrichia oblita
摘要
Abstract
To assess the potential of mulch as a physical barrier against northern China scarab beetle Holotrichia oblita,ten types of mulch were tested in laboratory bioassays for their effects on adult emer-gence,entry into soil,survival,and oviposition,with further validation in field trials.Laboratory results showed that during the first emergence period,adult emergence rates under all mulch treatments were significantly lower than those in the control,with the 15 μm white mulch and the 14 μm black mulch exhibiting the best barrier effects.However,after three emergence periods,these effects were largely diminished.The results of the entry rate tests were consistent with those of emergence.Mulch treat-ments had no significant effect on adult survival,with survival rates remaining above 90.00%after three emergence periods.After continuous coverage for 21 days with the 15 μm white mulch and the 14 μm black mulch,the number of H.oblita's eggs in the treatment plots was significantly lower than in the control,while no significant differences were observed for the other eight mulch types.Field trials dem-onstrated that grub densities and pod damage were both significantly lower in mulch-treated plots than in control plots,with an average reduction of 84.34%in grub density and 10.20 percentage point in peanut pod damage.These findings indicate that mulching can disrupt the emergence and entry rhythms and oviposition behavior of H.oblita,thereby suppressing population growth and crop damage.关键词
