摘要
甜菜夜蛾Spodoptera exigua是一种全球分布、间歇性发生的农林多食性害虫,给全球多种农作物和园艺作物造成严重的经济损失.2022年在河南省安阳县林场苗圃基地调查时发现一种昆虫为害侧柏叶片,我们对其进行了形态学鉴定,并利用线粒体细胞色素氧化酶基因(CO Ⅰ)进行了分子鉴定,证实该虫为甜菜夜蛾.本文简要描述了该虫为害特点以及生活习性,并对该虫在不同区域的为害情况进行了调查.本文是首次报道侧柏可以作为甜菜夜蛾的寄主,研究结果为进一步研究甜菜夜蛾在侧柏上生物生态学及防治技术提供基础数据.
Abstract
Spodoptera exigua(Hübner)(Lepidoptera:Noctuidae)is a globally distributed and intermittent polyphagous pest in agriculture and forestry,which inflicts serious economic damage on many agricultural and horticultural crops.In our investigation,we found that an insect damaged the leaves of Platycladus orientalis at the nursery base in Anyang county,Henan province in 2022.Morphological identification and molecular characterization using mitochondrial cytochrome oxidase subunit Ⅰ(CO Ⅰ)gene confirmed that the collected insect was S.exigua.We also briefly described the damaged characteristics of the pest and its life behavior on P.orientalis.Further,Investigation was conducted to determine the damage situation of the insect in different regions in Henan province.This is the first report of infestation by beet armyworm on P.orientalis.These results will provide the basic information for future monitoring and pest control of S.exigua in P.orientalis.
