| 中文摘要: |
| 以云南河口坝洒农场土沉香林为例，通过对其炭疽病、黄野螟进行1 年的调查，结果显示：（1）
该地区土沉香炭疽病流行方式为渐发型，流行曲线以多峰波浪型为主，平均危害率为8.7%，病情指数平均值
为1.79，危害高峰期为5 月和9 月，发病率较低且危害级别较轻；（2）黄野螟危害具有发生面广、级别较重、
虫口密度较大的特征，平均虫叶率为9.0%，百叶虫量平均值为22.3 头，危害高峰期为3~4 月和10~12 月；
（3）炭疽病和黄野螟的发病规律与气候因素之间存在显著或非显著相关关系，日照、气温和湿度是主要影响
因素。 |
| 英文摘要: |
| Taking the Aquilaria sinensis bruce of Basa-farm in Hekou as object，authors researched and
investigatied Anthracnose and Heortia vitessoides for one year. The results showed that The Anthracnose spreaded
gradually，the epidemic curve was multimodal and wave，the damage rate was 8.7%，the disease index was 1.79，
hazard peak periods were May and September，the incidence of disease was low and the disease index was lighter.
The Heortia vitessoides damage occurred widely，the disease grade was heavy and the population density was big，
the insect leaves rate was 9.0%，the insect amount from one hundred leaf was up to 22.3， the hazard peak periods
were March to April and October to December. The incidence regularity of Anthracnose and Heortia vitessoides had
significant or not significant correlation with climate factors， the main influence factors were sunlight， temperature
and humidity. |
