为明确暗黑鳃金龟(Holotrichia parallela Motschulsky)性诱剂对成虫的引诱效果及对幼虫虫口密度的降低作用,在全国主要花生产区开展了田间诱捕试验,调查诱捕成虫数、幼虫减退率及对花生的保果效果。结果表明:一台诱捕器一天内诱到的最大成虫数为977头;幼虫减退率最高可达78.8%,保果效果最高可达68.6%。表明暗黑鳃金龟性诱剂对成虫有很强的引诱效果,并能明显减轻幼虫为害。
In order to clarify the inducing effect of Hollotrichia parallela Motschulsky sexually attractant on adults and the reduction of larval population density, field trapping experiments were conducted in the major flower-producing areas of the country to investigate the number of trapping adults, the reduction rate of larvae, The effect of the preservation of fruit. The results showed that the maximum number of adults induced by a trap in a day was 977, the highest reduction rate of larvae reached 78.8%, and the highest fruit protection effect reached 68.6%. The results showed that the dark-lipped beetle lure had strong attraction to adults and could significantly reduce larval damage.
