有害生物——三叶斑潜蝇 总被引:1,自引:0,他引:1
三叶斑潜蝇Liriomyza trifolii(Burgess)隶属双翅目,潜蝇科,斑潜蝇属,三叶斑潜蝇又称为三叶草斑潜蝇。三叶斑潜蝇被列入农业部2006年3月2日公布的《全国农业植物检疫性有害生物名单》,取代美洲斑潜蝇成为国内检疫性害虫。由于是新人侵害虫,许多植保工作者,特别是基层植保工作者对其形态特征、危害症状、生物学特性、寄主植物、防控措施等都不是很了解。现根据搜集积累的资料对三叶斑潜蝇作一概述,以供参考。 相似文献

三叶斑潜蝇的检疫处理 总被引:3,自引:1,他引:3
三叶斑潜蝇Liriomyzatrifoli(Burgess)是观赏植物及农作物的重要害虫之一。据统计,1980年三叶斑潜蝇在美国爆发,芹菜业的损失达900万美元;1981~1985年,加利福尼亚州因此虫危害,导致菊花业损失达9300万美元[1]。19... 相似文献

江苏省三叶斑潜蝇发生调查及分子检测 总被引:2,自引:0,他引:2
2009年对江苏省斑潜蝇的发生分布进行了调查,并利用形态和分子生物学技术对采集标本进行鉴定,结果表明:三叶斑潜蝇在江苏除徐州和淮安外的11个市均有发生,尤其在江苏的苏中和苏南地区发生更为严重。江苏三叶斑潜蝇与国内测序并登录在GenBank中的序列具有99%甚至100%的相似性;与国外三叶斑潜蝇序列也具有99%以上的相似性,但其覆盖率都未达到100%。同时,多序列比对结果显示江苏省三叶斑潜蝇在测定的800 bp范围内仅存在一个明显的变异位点。此外,在本次调查中发现,除三叶斑潜蝇外,在江苏为害蔬菜的斑潜蝇还有美洲斑潜蝇和番茄斑潜蝇。 相似文献

Abstract Liriomyza trifolii Burgess had first been reported from Senegal in 1980. Field surveys in 1982 revealed its presence in all vegetable growing areas of the country, heaviest damage being registered in the Cap Vert. Five indigenous eulophids (larval parasitoids) plus five other rare parasitoids, frequently parasitized over 90% of the flies. These rates were higher in insecticide free fields, and very much above the 30–40% reported for 1981. The most important parasitoids were Hemiptarsensus semialbiclava (Girault), which dominated in the second half of the dry season, and two Chrysonotomyia spp., which were more abundant in the rainy season. Surveys for exotic parasitoids indicated Diaulinopsis callichroma Crawford from Trinidad to be a promising species for introduction in the New World. This parasitoid, together with eight other chalcidoids (mostly larval parasitoids) and two braconids (larval‐pupal parasitoids), were collected in the field or received from established insectary cultures. They were studied and shipped for rearing and release in Senegal. Nine species were released at the end of 1982 and in 1983. Many were recovered shortly after release, but only Opius dissitus Muesebeck was recovered in later samples and became relatively abundant. 相似文献

斑潜蝇隶属双翅目(Diptera)潜蝇科(Agromyzidae)斑潜蝇属(Liriomyza),是一类重要的农业害虫。近年来,随着海峡两岸果蔬贸易的快速发展,斑潜蝇类害虫传入大陆地区的风险明显增加,植物检疫部门急需该类害虫的快速鉴定技术和方法。本研究针对我国进境检疫性害虫三叶草斑潜蝇(L.trifolii),在检测和检索其线粒体DNA细胞色素氧化酶I(mtDNA COI)基因序列并与其近缘种美洲斑潜蝇(L.sati-vae)和南美斑潜蝇(L.huidobrensis)相同基因序列比对的基础上,设计并筛选了其种类识别特异引物,初步实现了三叶草斑潜蝇的快速鉴定。 相似文献

Liriomyza trifolii (Burgess) is a highly invasive species that has become established in agricultural and ornamental crops throughout the world. L. trifolii was first recorded in China in 2005 in Guangdong Province. Subsequently, its known distribution in China has rapidly expanded to another 11 provinces (Zhejiang, Jiangsu, Shanghai, Fujian, Guangxi, Shandong, Hainan, Hebei, Henan, Hubei and Anhui), where it is currently causing considerable damage and economic losses. Experimental research and field surveys have contributed to our understanding of the ecology of L. trifolii and particularly the process of invasion and its interactions with other established, exotic Liriomyza leafminer species. A number of factors have contributed to the successful establishment of L. trifolii and displacement of interspecific competitors. In China, L. trifolii has become a particularly devastating pest in areas with intensive farming with extensive monocultures and a reliance on insecticide use. Integrated pest management incorporating judicious applications of insecticide combined with biological and cultural controls is likely to provide the best long‐term management strategy for L. trifolii. We provide information regarding 10 years of L. trifolii invasion in China and discuss areas of future research to enhance our overall understanding of the biology and ecology of L. trifolii and to improve management programmes for this widespread invasive insect pest. © 2017 Society of Chemical Industry 相似文献
