Analysis of covariancc was used in the studies. It was shown that there was no significant difference between two counties, Zhen-hai and Wen-ling, as to the effective thermal constant and the threshold temperature of development of colony pupae at both the initial peak and the peak of the overwintering generation in the field, and that there was significant difference between the threshold temperature of development at the initial peak and the peak of colony papae in the field.

Analysis of covariancc was used in the studies. It was shown that there was no significant difference between two counties, Zhen-hai and Wen-ling, as to the effective thermal constant and the threshold temperature of development of colony pupae at both the initial peak and the peak of the overwintering generation in the field, and that there was significant difference between the threshold temperature of development at the initial peak and the peak of colony papae in the field. But the thermal constants were not statistically different.The following are two corrected regression equations ( or predicting formula ) for the initial peak and the peak of colony pupae of the overwintering coueration. They proved accurate in the test in Zhen-hai and Wen-Ting gen-nties and are believed to be suitable for use in production.yc( ini. ) = 11.06+124.33x, or Nc ( ini. ) = 124.33/ ( y - 11.06 )yc ( pea. ) = 11.66 + 124.33x, or Nc ( pea. ) = 124.33/ ( y - 11.66 )

本文应用协方差分析法,分析了二点螟越冬代群体蛹的有效积温和发育起点温度,结果是:田间越冬代始盛群体蛹的有效积温和发育起点温度,镇海和温岭两地间无显著差异;田间越冬代高峰群体蛹的有效积温和发育起点温度,镇海和温岭两地间亦无显著差异。田间两群体蛹(即始盛蛹和高峰蛹)间的有效积温亦无显著差异;而发育起点温度却有极显著差异。得田间越冬代始盛和高峰两群体蛹的矫正回归方程(或称预测式): Yc(始)=11.06+124.33X,或Nc(始)=124.33/(Y-11.06) Yc(高)=11.66+124.33X,或Nc(高)=124.33/(Y-11.66) 上述二式,在镇海和温岭两地验证结果,准确性较好,可以在生产上应用。

The Scale-insect, Quadraspidiotus gigas is one of the important pests in poplar plantation. With the aim to establish the scientific management system of Q. gigas rapidly, we conducted the studies on the time and raethods of applying chemical and biological control based on taking the chemical control as an argent measure. Result of the field tests conducted in 1984—1986 showed that the high time for chemical control vas in the abundant emergence period of female adults and hatching period of newly hatched larvae. It was about on May 15th, and June 25th in suihua respectively. Preventing its an important natural enemy parasitic aphidcholcid from being killed, the most effective chemicals abfaired from the tests was D-T-4, C-T-3, A-T-1, B-T-2, and other contact insecticides in controlling adults. The corrected mortality was over 84%. In control period of newly hatched Larvae, B-T-2, A-T-1, C-T-3, D-T-4 and other some contact insecticides was the most effective. The mortality was over 94%. The method of using brush to brush off scale-shells, then spraying or trunks has been proved to be more effective.

杨圆蚧(Quadraspidiotus gigas)是危害物树人工林主要害虫之一。为尽快建立起杨圆蚧害虫科学管理体系,以化学防治为应急措施,较系统地研究了杨圆蚧地防治时间、药剂种类、施药方法,协调化学防治与生物防治的关系等项内容。1984—1986年试验,杨圆蚧化学防治的最佳时期是雌成虫羽化盛期和初孵若虫的孵化盛期,在绥化地区的时间分别为5月15日左右和6月25日左右,同时还避免对杨圆蚧主要的天敌——蚜小蜂地杀伤。在成虫防治期,杀虫效果最佳的为杀虫优(一、二号)、D-T-4、C-T-3、A-T-1、B-T-2、防蚧油触杀型药剂,校正死亡率都在84%以上。在初孵等若虫防治期,杀虫效果最佳的为杀虫优(一、二号)B-T-2、A-T-1、C-T-3,D-T-4、杀蚧油、DDVP柴油等触杀型药剂,效果都在94%以上。在施药方法上先把杨圆蚧壳刷掉后,再行涂干或喷干效果最佳。

The purpose is to forecast whether a man-caused fire occures in a forestry bureau on some day. A linear discriminant function and discriminant criterions were developed using data collected from Daxing′-anling region from 1975 to 1984 (10 years). For the forecast backwords of 1984 and forecast forward of 1985 and 1986, the ratio of correct discriminating that a fire will occure in a day is 79.1%, 87.0%, and 80.1%, respectively and ratio of correct discriminating that a fire will not occure in a day is 83.2%,...
