刺槐的新害虫上海勾天牛和短翅勾天牛
New pest insects against Robinia pseudoacacia:Exocentrus zikaweiensis and Exocentrus savioi
摘要
Abstract
To better monitor and control the trunk borers in Robinia pseudoacacia forests to avoid tree death,the species of pest insects were investigated.Two species of small longhorn beetles were collected from dead R.pseudoacacia or its withered branches in Qingdao region.The species were identified by morphological observation and phylogenetic analysis of mitochondrial cytochrome c oxidase subunit I(COⅠ)gene sequence.The two species had backward-directed triangular short spines on both sides of the pronotum,which accorded with the characteristics of Exocentrus;one with uniform brown elytra lacking patterns,the other with black elytra bearing an arrow-shaped patch on one third of the end.The two longhorn beetles were identified respectively as Exocentrus zikaweiensis and E.savioi based on morphology and COⅠ gene sequences phylogenetic tree(maximum likelihood method).Two species were new pest insects against R.pseudoacacia and new records for Shandong province.These results can serve as a guideline for developing pest control strategies in black locust forests.关键词
