Under the conditions of our insectary with T 27×1℃, RH 70-80%, photoperiod 14 hrs/day, light intensity 250-510 Lux, Anopheles sinensis larvae were fed with rabbit liver powder and yeast, while adults with mouse blood and 10% glucose. The growth of three different geographical strains - Zhengzhou (Henan Province), Shanghai, Youxi (Fujian Province) were studied in the periods of Nov-Dec 1980, Mar-Apr 1981 and Mar-Apr 1982. The authors established their life tables and calculated the corresponding parameters, such...

Under the conditions of our insectary with T 27×1℃, RH 70-80%, photoperiod 14 hrs/day, light intensity 250-510 Lux, Anopheles sinensis larvae were fed with rabbit liver powder and yeast, while adults with mouse blood and 10% glucose. The growth of three different geographical strains - Zhengzhou (Henan Province), Shanghai, Youxi (Fujian Province) were studied in the periods of Nov-Dec 1980, Mar-Apr 1981 and Mar-Apr 1982. The authors established their life tables and calculated the corresponding parameters, such as the innate capacity for increase, the net reproductive rate, etc. Age-specific survival rate curves and fecundity rate curves of the three strains were drawn. Using analysis of variance, their predominant tests were performed. The results indicated that all the values expressed no significant differences (P>0.05) with the exception of the life expectancy of the two sexes (P<0.01). The three strains of A. sinensis above mentioned are very closely related according to the characteristics of life tables.

在相同时间、相同实验条件下,对河南郑州、上海、福建尤溪三地区中华按蚊进行了种 群动态的实验研究,求出各株的生命表和有关种群参数,以方差分析法进行相应生物学特性的显著 性检验,除两性按蚊寿命有非常显著差异(P<0.01)外,其余各对应值均无显著差异,从而认为三 株中华按蚊的生命表特性非常相近。

The investigation of natural population dynamics of An sinensis had been carried out in Zhengzhou suburb in July-August, 1983 and 1984 respectively.By means of maths model, the finite natural increase rate of generati- ons and the population dynamics parameters in June, July, August of both years were obtained. As compared with the corresponding parameters of the experimental population, they are much lower except the percentage of survival adults after 12 days and mean length of generation.The result showed...

The investigation of natural population dynamics of An sinensis had been carried out in Zhengzhou suburb in July-August, 1983 and 1984 respectively.By means of maths model, the finite natural increase rate of generati- ons and the population dynamics parameters in June, July, August of both years were obtained. As compared with the corresponding parameters of the experimental population, they are much lower except the percentage of survival adults after 12 days and mean length of generation.The result showed that natural factors as well as natural enemies have great effect in the composition of environmental resistance to An. sinensis The parameters of natural population dynamics of An. sinensis will be important significant to establish the control programme against malaria and its vector.This thesis first suggested a maths model at last time of oviposition.

983年7、8月和1984年7、8月,在郑州市郊进行了中华按蚊自然种群动力学的调查研究。以获得的各项数据,引用数学模型,计算出各年该蚊第六、七、八世代的净增殖率和有关种群参数值。与该蚊实验种群相应参数做比较,除12天后成蚊存活百分比和平均世代周期长相近外、其余各参数值均明显偏低、说明野外自然因素和天敌对中华按蚊所构成的环境阻力是相当大的。该蚊自然种群动力学参数值的求出对防蚊灭疟策略的制订具有重要意义。该文首次提出求最后产卵日期的数学模型。

In the in-core fuel management model that has been developed in this paper, the fast group parameter is calculated using B_1 approximation and the thermal group parameter using the first flight collision probability method, but the critical and depletion calculations are based on the coarsemesh method.The nodal imbedded calculation, combined with the coarsemesh calculation, can give ths detailed flux and power distribution in assemblies.
