为明确在浙江省是否有扶桑绵粉蚧的分布及其危害情况,在全省范围内对高风险地带开展全面调查.结果显示,在浙江省杭州、金华和丽水地区的9个县市区发现有扶桑绵粉蚧,发生面积11.09 hm2,查到扶桑绵粉蚧的寄主植物33科66种,扶桑绵粉蚧嗜好菊科、葫芦科、茄科、锦葵科、马齿苋科、胡麻科、马鞭草科、报春花科和石蒜科植物,以芝麻、南瓜、茄子、栝楼、枸杞、大花马齿苋、马缨丹、胭脂花、菊花、朱顶红、棉花、木槿、苍耳、小白酒草和苦荬菜受害最严重.上述结果表明,扶桑绵粉蚧在浙江局部地区已有分布,虽然目前分布面积不大,但必须警惕其进一步扩散蔓延. 相似文献

番石榴果实蝇Bactrocera correcta(Bezzi)严重为害番石榴、莲雾、芒果等果蔬植物,我国将果实蝇属Bactrocera (非中国种)列为进境植物检疫性有害生物。2021年10月至2022年6月,在海南省三亚市崖州湾科技城内连续9个月诱捕到疑似番石榴果实蝇成虫。本研究通过形态特征、DNA条形码和常规PCR等方法,对诱捕到的疑似样品进行了鉴定。鉴定结果表明,诱捕到的实蝇样品为番石榴果实蝇,相关植物检疫机构需进一步加强海南地区番石榴果实蝇的检疫、监测及防控。 相似文献

The primary purpose of a national plant protection organization is to prevent the spread of quarantine pests. Such pests are characterized according to their predicted capability to be of economic importance in new areas. The determination of the potential of an exotic pest to cause crop losses is a preliminary component in a pest risk assessment (PRA) process. The initial PRA step includes two distinct ecological analyses. The first must predict the expected extent and frequency to which a new pest population will attain and/or surpass the economic injury level. This is necessary to justify the classification of an exotic pest as being of quarantine significance. Secondly, a PRA must estimate the likelihood of establishment for those quarantine pests for which an entry pathway exists. Both require that bioclimatic comparisons be made between the areas of origin and distinct target destinations. The bioclimatic methodologies of the past are currently being enhanced to specify more precisely‘quarantine pest zones of ecological equivalency’, i.e. areas within which the behavior of a specific quarantine pest can be expected to be the same. The information derived from studies that provide a basis for forecasting the behavior of indigenous pests can also be used in PRA. 相似文献

考虑灌溉及气候变化条件下葡萄花翅小卷蛾在中国的潜在地理分布 总被引：1，自引：0，他引：1
葡萄花翅小卷蛾Lobesia botrana(DenisSchiffermüller,1775)是我国重要的检疫性害虫,目前尚未传入我国,为了解该害虫在中国的潜在地理分布,根据该物种在全球已知的最新分布情况,利用CLIMEX 4.0.2在考虑灌溉条件的情景下,预测其在不同气候条件下的潜在地理分布。结果显示,葡萄花翅小卷蛾在我国的潜在地理分布范围较广,我国的主要葡萄产区均为葡萄花翅小卷蛾的适生区,且随着气候变化,至2030年,葡萄花翅小卷蛾在我国黑龙江、青海、四川省的部分适生区有所增加,适生程度也有所提高。因此应加强对葡萄花翅小卷蛾的检疫力度,防止其传入我国,保护我国葡萄种植业的生产安全。 相似文献

Tilletia indica, the fungus responsible for Karnal bunt disease of wheat, is currently recognised as a quarantine pest by both the EU and
EPPO. The evidence that has been used to justify this status is reviewed and found to be in need of reappraisal. Yield losses
caused by the pathogen are insignificant and disease levels are rarely high enough to cause serious quality problems. The
sole reason for its designation as an important quarantine pest would seem to lie in the serious implications for trade should
the pathogen be detected in an exporting country. Since there is strong evidence to suggest that T. indica may not even establish in Europe, it would seem logical to reclassify the pathogen as the cause of a minor disease that is
likely to have little quarantine significance for Europe. However, since most wheat-growing countries have strict quarantine
regulations aimed at preventing the introduction of T. indica, this reclassification is unlikely to occur unless plant health authorities around the world can agree on a new status of
reduced importance for T. indica that suits its actual potential as a pest.
