| 摘 要： | 紫薇梨象Pseudorobitis gibbus Redtenbacher是一种严重危害紫薇的新害虫。紫薇梨象在泰安1年发生1代,以幼虫或成虫在被害果实内休眠越冬。越冬幼虫在翌年5月前后化蛹,5月中下旬羽化,6月上中旬进入成虫盛发期,产卵集中在7月下旬—8月中旬,并且虫态交错现象严重。入冬后的蛀果率高达60%以上,对紫薇的观赏价值和种实繁殖构成很大的威胁。紫薇梨象成虫具有假死性和较强的趋光性,耐饥能力一般为36h。成虫对类似于植物蜜源的蜂蜜具有显著趋向性;对类似于食用醋的酸性挥发物质有较强的忌避性。紫薇在园林绿化中的大量应用,将加剧紫薇梨象的地理扩散,对山东周边省份乃至全国的紫薇构成潜在威胁。建议采用物理防治,同时利用天敌及性引诱剂等生物措施来综合防治紫薇梨象。 |

| Abstract: | The weevil Pseudorobitis gibbus Redtenbacher(Coleoptera:Apionidae) is a new and important pest of Lagerstroemia indica.P.gibbus is univoltine with only one generation per year and in Tai'an overwinters as either dormant larvae or adults.Winter larva turn into pupa the following May and emerging adults were found in middle to late June.Eggs are laid between late July and mid-August.The proportion of fruits damaged by larvae was >60%;sufficient to pose a threat to the ornamental value and reproduction of L.in... |
