摘　　要：通过对云南河口地区橡胶炭疽病、六点始叶螨进行连续监测,并收集相关气象资料,结果显示：（1）该地区橡胶炭疽病主要在嫩叶时期发生和流行,流行以多峰波浪型和单峰弓型为主,每年有2次危害高峰,菌量和感病组织是病害流行的基本条件,高温多雨是病害流行的主导因素;（2）六点始叶螨流行方式为渐发型,每年通常有2～3个高峰期,分别发生在4月、6月和9月,连续的晴朗干旱天气有利于六点始叶螨的繁殖及爆发,而阴雨潮湿天气能抑制六点始叶螨的危害程度;（3）在相同的气候类型、橡胶品系及立地环境条件下,不同海拔高度的橡胶炭疽病、六点始叶螨发病规律基本一致,但年际变化规律及变化幅度有所不同,而相同海拔高度的橡胶炭疽病和六点始叶螨之间存在非显著正相关关系。The occurrence regularity of Anthracnose, Eotetranychus sexmaculatus （ Riley ） in rubber plantation was monitored and weather data was collected in Hekou, Yannan province. The results showed that： The rubber Anthracnose was mainly occurred and spread during the young leaf period, and it spread mainly a wavy line with several peaks and a bowed line with one peak. There were 2 harmful peaks every year, the bacteria amount and infected tissues were the basic conditions for the epidemic, whereas rainfall and high temperature were the prevailins factors invoking occurrence of the epidemic. The spread path of E. sexmaculatus occurred gradually, it usually had 2-3 peaks every year, and it occurred in April, June and September. The continuous clear and dry weather was benefit to the propagation and outbreak of E. sexmaculatus, while the overcast and rainy damp weather could inhibit its damage degree. The incidence regularity of rubber Anthracnose and E. sexmaculatus from different altitude was basically alike in the same climate type, rubber strain and site conditions, but the interannual variation and rangeability were different, there was a nonsignificant correlation between the rubber plantation＇ s Anthracnose and E.sexmaculatus at the same altitude.
