【摘要】 经过2008年对夏直播花生高产试验中18个小区地下害虫危害花生荚果的调查分析,发现金针虫是危害夏直播花生荚果主要害虫之一。金针虫危害比率大,危害果数可达虫害果数的50.0%~84.05%,平均64.57%,占总果数的14.55%,接近蛴螬危害的2倍;其危害症状与蛴螬明显不同,会严重降低花生产量和品质,虫害果数量与有效产量呈高度负相关关系。因此在生产中应加强对金针虫的防控。更多还原

【Abstract】 Elateridae is one of the pests that can bring serious damage to peanut pod through investigation made in summer-sown peanut field in 2008.The number of pod damaged by elateridae accounted for 14.55% of total pod and for 50% to 84.05% with total damaged pod.The mean level of pod damaged by elateridae was 64.57% and accounted for about 2 times of that damaged by grub.The number of damaged pod showed highly negative relationship with effective output.Elateridae is one of the main harmful insects to summer-sown peanut pod from pod-bearing to harvest period.It can decrease the peanut output and quality seriously.Therefore elateridae should be prevented and controlled.更多还原
