Tea-bagworm is an important pest of tea-plant in some tea growing districts in Anhwei, Chekiang, Fukien, Taiwan, and Hunan Provinces. The larvae infest the leaf, bark and husk of fruit, causing a considerable damage to the tea plants. The present paper deals with the general morphology, biological investigations and control measures of the pest. Both laboratory and field trials were conducted at the Chekiang Agriculture College and at Lung-thing (龙井) Tea Plantation, Hanchow, during the years 1953-1956. The tea-bagworm gives two generation annually and over-winters in larval stages. The male moth is winged; the female is wingless, concealing itself and depositing eggs in the case. After hatching, the larva leaves the case, then weaving a new conical shaped case with a few fragments of tea leaves. Under sunshine the larvae usually stay on the underside of the tea leaves and among the tea bushes. There have been found hymenopterous larval parasites, of which five are Ichneumonids and one is Chalcid. These parasites usually cheek the outbreak of the second brood of the pest. Basing on results of experiments performed, the following measures of control are suggested: 1. Spraying with 6% wettable 666 at the rate of 1:200-400 dilution after the picking season, gives promising results. There appeared to be no disagreeable odor or taste of 666 in the leaves sprouted out from sprayed buds. 2. Spraying with Derris and Pyrethium, during the picling season. 3. Hand-picking the larval cases and hanging cases to potect the hymenopterous parasites.

五、摘要 1.茶小簑蛾是茶树上的一种主要害虫,我国台灣、福建、浙江、安徽、湖南等茶区均常發生。幼虫食害茶叢叶片、小枝皮層和果皮,因此茶叶的常年損失达10—50%。 2.該虫在杭州年生二代,3月中旬到5月下旬和6月中旬到8月中旬为害茶叢,3—5月間最为严重;以3龄或4龄幼虫在茶叢上越多,賴幼虫爬行,吐絲和人工移植茶叢或茶苗傳播,在茶园中多系局部为害,扩散力不大。 3.成虫雌雄異态,雄蛾日間活动,雌虫似蛆狀,終生藏于囊內,卵产在护囊内。幼虫孵化离开母囊后即能制囊以藏身,囊外附有茶叶和小枝皮的碎片;活动时背負护囊迁移和取食,日光照射时幼虫躲在叶背和茶叢間。 4.在采茶結束和茶芽休眠时噴用6%可湿性666的200—400倍液,基本上能抑制此虫發生;采茶时噴用除虫菊或魚藤肥皂液;噴用时药液約需比一般增加一倍左右。此外必須配合人工捕捉虫囊和保护寄生蜂。最好在5月到6月上旬間和7月中旬到8月中旬間采摘早期挂起的虫囊。

This paper attempts to answer the following two questions: (1) Is it possible to derive the law of distribution of hydrological frequency theoretically(2) What type of distribution curve should be adopted as the model of hydrological frequency curve and how to determine their parameters? The results obtained may be summarized as follows: 1. Hydrological phenomena are time series with concealed periodic fluctuations. The results from statistical analysis based upon the current assumption that hydrological phenomena are independent stochastic variables should be accepted with due considerations. 2. In view of the regional nature of hydrological phenomena, the current parctice of analyzing samples taking from a single station only is, in effect, to narrow the sampling field arbitrarily from a larger area to a point, thus reducing the accuracy of the statistical results. Hence, the synthetic utilization of the data of all stations within the hydrologically homo- geneous region is an important measure to increase the accuracy of statistical analysis. 3. The belief that the flood frequency obeys the binomial theorem or Poisson's theorem is but to mix up the priori with the empirical probability problem. The binomial theorem, being a powerful weapon to deal with the problems of priori probability, has not been adquately and properly utilized in the hydrologieal frequency analysis. 4. Analyses have been made of the nature of distribution of shydrologieal series on the basis of Kaptyen's derivation of the skew distribution, which indicate: (1) That the theoretical interpretation of the log-probability law of the hydrologic phenomena by V. T. Chow is not sound; (2) that hydrologic phenomena being results of very complicated meteorological and hydrological processes, it is impossible to derive theoretically the law of distribution for the hydrological series. 5. The view that the flood frequency obeys the Gumbel's distribution is theoretically not sound and also not verified by actual data. 6. According to the nature of the mathematical treatments applied, the method of description of the empirical probability can be classified into three systems: (1) The methods of the generalization of the characteristic factors of the distributions, such as Pearson's curves, Goodrich's curves, etc.; (2) The methods of the modification of a fundamental distribution by series and polynomials, such as Gram-Charlier curves. curves, etc.; (3) The methods of transformed functions, such as the log-probability law, curves, etc. It should be remarked that not only Pearson's and Goodrich's curves are frequency curves of empirical nature, but even the theoretical laws, such as the normal law and the log-probability law, will be aceepted as curves of empirical nature, when used as models for empirical probability problem. 7. Hydrological frequency analysis should not be mystified and made absolute. Instead of free selections, the models of hydrological frequency curve should be uniquely selected and specified. Statistical parameters should be determined not solely by the short period data of single station, but also by the synthetic utilization of the data of possible more stations. 8. It is recommended that one of the two types of distribution, i.e. the log-normal frequency curve with both sides limited and the Pearson's type Ⅲ curve, may be selected as unified models. The author suggests that the K-value corresponding to recurrence intervals of say 10~4, 10~5, or 10~6 years may be selected as the upper and lower limits for the log-normal curve. For Pearson's type III curves, C_s should be treated not as independent but as dependent variables of C_v. 9. The proper way to select and determine the model frequency curve is to see whether it fits well with the actual data of grouped stations (stations to be grouped by regions for rainfall data and by C_v for runoff data) and the reasonableness of the extrapolating part. 10. Suggestions on the method of determination of x and C_v: For point rainfall, iso-x map may be utilized, and the mean C_v for each hydrologicregion may be adopted in order to minimize the errors from single stations and to avoid the discrepancies in results obtained from the same region. With regard to flood frequency analysis, flood mark reconnaissance must be utilized to determine the magnitude and the recurrence interval of the unusual flood. The x and C_v values of the floods and runoffs of hydrologically similiar river basins may be compared. Besides, the reasonableness of the results of frequency calculations as well as of the statistical parameters adopted therein may be checked by comparing runoffs and point-rainfall values of the same frequency.

我国近期水文频率计算方法的研究工作在选择方法,经验频率公式,参数的误差和利用我国水文资料检验各种频率线型等方面有了一定的成果和实用的结论[1],但是下面两个问题还没有获得解决: (1)能否从机率理论证明水文频率属于何种分布律? (2)水文频率曲线应当采用什么线型?如何确定参数?本文试图解答以上两个问题。本文分析了水文系列的时序性质和区域性质,把机率问题按先验、极限和后验三种基本性质对水文频率问题进行了分析;利用开布屯推导偏态分布的方法分析了水文系列的分布性质,并从而批判了有关水文频率肯定属于对数正态律,耿贝尔极限律或二项式定理等等说法。认为属于后验机率性质的水文频率,不能从机率理论证明它属于何种分布律。最后提出联合利用各站水文资料来选择线型和确定参数的方法,并建议在两端有限对数正态和皮尔逊Ⅲ型两种线型中选择一种作为统一采用的线型,对两端有限曲线提出了简易可行的确定上下极限的方法,对皮尔逊Ⅲ型曲线认为应该把Cs作Cv的倚变参数。
