本文根据国外文献报道和国内检疫截获记录,整理出有谷斑皮蠹分布的国家62个,其中发生严重的国家15个。根据Howe等人提出的适于谷斑皮蠹定居的3个气候标准,对我国486个气象站的温湿度记录(1961～1970年)进行了分析;对提出的3个气候标准进行了评述,认为标准2虽与当前谷斑皮蠹为害严重的地区更吻合,但该标准对湿度要求偏严;标准3虽降低了对湿度的要求,但划出的区域仍不能包括谷斑皮蠹的部分发生地。作者认为,在考虑适生范围时,重点应考虑温度的因素,但湿度对谷斑皮蠹的虫口密度有重要影响。主要根据标准1,将我国划分为适生区及非适生区。分别根据适生区内相对湿度在50％以下或每年连续6个月以上月平均温高于20℃划分出第一特别危险区和第二特别危险区;我国东半壁的适生区除去第二特别危险区之外的部分规定为危险区。文中对谷斑皮蠹的检疫对策提出了建议和讨论。
In this paper, according to foreign literature and domestic quarantine interception records, sorted out the distribution of Guppy beetles 62 countries, of which 15 were serious in the country. According to the three climate criteria proposed by Howe et al. For the settlement of M. pestis, the temperature and humidity records (1961-1970) of 486 weather stations in China were analyzed. The three proposed climate criteria were reviewed, Although Standard 2 is more consistent with current areas where the damage is more severe, the standard is more stringent for humidity; Standard 3 reduces the humidity requirements but the area covered can not include the part of the pest Occurred. In the authors’ opinion, the temperature should be taken into account when considering the suitable range of habitat, but the humidity has an important influence on the population density of the pest. According to Criterion 1, our country is divided into suitable areas and non-suitable areas. The first special danger area and the second special danger area are respectively classified according to the relative humidity below 50% in the habitat area or the average monthly temperature above 20 ℃ for more than 6 months in a year. The second The part outside the special danger zone is defined as the danger zone. The article put forward suggestions and discussions on the quarantine countermeasures of Pterostilbene.
