世界茶树病虫区系分析(英文)

An Analysis on the World Tea Pest Fauna

根据对1900—1987年世界茶树病虫区系的分析研究,全世界已报道的茶树害虫(包括害螨)有1034种(我国有430种),茶树病原(包括线虫)有500种(我国有133种)。无论是世界各产茶国或我国各产茶省范围内,茶树害虫和病原种类数与种植年限及种植面积有明显的依存关系。在两者作用的相对重要性上,年限是第一位的,在达到一定种植年限后,面积的作用逐渐增大。本文对世界茶树害虫和病原区系从生物地理学和分类学角度进行分析,并提出了在一个辽阔的空间范围(如一个国家)内茶树害虫达到饱和的年限约为100—150年。

According to the investigation and analysis on the world pest fauna of tea plant published in the period of 1900—1987, 1034 species of tea insect pests (including mites) and 500 species of plant pathogens (including nematodes) were recorded in the world, and 430 species of insect and mite pests as well as 133 species of plant pathogens and nematodes were recorded in China. Analysis indicated that a closely relationship was established between the numbers of pest species and the age as well as area of tea cultivation in China or in world scale. With regard to the relative importance of the above two factors, the age of tea cultivation played a primary effect, and the area of cultivation played an additional effect only after following the influence of age. A suggestion that the saturation level of tea pests in a vast space area (such as a country scale)would be reached in a period of 100—150 years was put forward by the authors.
