Abstract

Adult and larval wireworm (Coleoptera: Elateridae) populations were surveyed in North Carolina sweetpotato, Ipomoea batatas (L.) Lam., fields during 2005 and 2006 by using yellow sticky traps and larvalbaits. Eight species of larvae and nine species of adult wireworms were identified. Conoderus vespertinus (F.) was the most prevalent wireworm species, making up 65.9% of the larvae and 62.9% of the adults captured. Adult C. vespertinus were most abundant in July, and larvae were smaller and more abundant after 15 July than earlier in the season, indicating an early summer generation turnover and oviposition in fields planted to sweetpotato. A significant positive relationship was observed between late-season abundance of C. vespertinus and the incidence of wireworm damage. Other wireworm species encountered were Conoderus amplicollis (Gyllenhal), Conoderus bellus (Say), Conoderus falli (Lane), Conoderus lividus (Degeer), Conoderus scissus (Schaeffer), Glyphonyx bimarginatus (Schaeffer), and Melanotus communis (Gyllenhal).

摘要

2005 年和 2006 年，在北卡罗来纳州的甘薯（Ipomoea batatas（L.）Lam.）田中，使用黄色粘性诱捕器和幼虫诱饵调查了成虫和幼虫的钢丝虫（鞘翅目：Elateridae）种群。鉴定出了 8 种幼虫和 9 种成虫钢丝虫。Conoderus vespertinus（F.）是最常见的钢丝虫物种，占捕获幼虫的 65.9％和成虫的 62.9％。成虫 C. vespertinus 于 7 月最为丰富，而幼虫在 7 月 15 日之后比季节早期更小且更丰富，表明初夏代更替和在种植甘薯的田间产卵。发现 C. vespertinus 的晚季丰度与钢丝虫损害的发生率之间存在显著的正相关关系。遇到的其他钢丝虫物种是 Conoderus amplicollis（Gyllenhal），Conoderus bellus（Say），Conoderus falli（Lane），Conoderus lividus（Degeer），Conoderus scissus（Schaeffer），Glyphonyx bimarginatus（Schaeffer）和 Melanotus communis（Gyllenhal）。
