In connection with experiments on the control of the rice stem borer, aseries of observations were conducted in 1949 to 1952 in Canton to determinethe form of the distribution of the moth, the egg-mass and the larval popula-tions of this species. It was found that the moth and egg-mass populations inrice seed-beds are in essential agreement with the random distribution of thePoisson series. The larval population in spring-crop fields apparently conformsto the contagious and the negative binomial distributions. The larval population during hibernation period appears to be neither of the random distribution norof the contagious type but agrees with the negative binomial distribution. The population distribution of the injured stems, characterized by the ap-pearance of "dead-hearts" and "white ears" was also studied. The "dead-hearts"popolation in autumn-crop fields conforms with the contagious and the negativebinomial distribution. The distribution of the "white ears" is not at random. It iseither in essential agreement with the contagious or with the negative binomialdistribution, depending on the size of the sampling unit. Based on the form of population distribution the questions of sampling tech-nique, the design of field experiments, the transformation of data for statisticalanalysis, as well as the habits and control of insects have been discussed inrelation to the rice stem borer. Since the populations of larvae and "whiteears" differ significantly from the random distribution, a new technique forsampling has been proposed. It is hoped that this may be useful in the investi-gations on the relative effectiveness of control operations and for census purposes.

Sugar cane borers infest the cane and cause a considerable injury to the plant in China. Four species of sugar-cane borers are commonly found in Kwangtung Province, viz. Diatraea venosata Wk., Chilo infuscatellus Snellen, Eucosma schistaceana Snellen and Sesamia inferens Wk.Trichogramma evanescens Westw. occurs in nature as an egg parasite of the sugar-cane borers.The present experiment on breeding Trichogramma centres around the ways of increasing its viability.The quality and the quantity of the nutrient for the larvae and adults of Trichogramma play an important role in relation to their viability. The contents of the egg of Sitotroga cerealella Oliv. which has been commonly used as a host of the Trichogramma are of poor nutrient quality and quantity for the larvae of this parasite. The eggs of Angoumois grain moth are so small that only one adult Trichogramma emerges from each egg. Such adults are usually smaller in size, less active and with lower reproductive potentiality as compared with those that emerge from the field hosts; besides, the female sex ratio gradually decreases in the successive generations.From the results of an experiment on Trichogramma breeding, it is found that the eggs of Attacus cynthia ricini Boisd. and of Dendrolimus sp. are the most suitable hosts for the propagation of Trichogramma evanescens. The adults of the parasites emerging from such eggs are generally large in size, very active and possess high reproductive potentiality; besides, the female sex ratio remains unchanged in the successive generations. Evidently, the quality and the quantity of the egg contents of these two species of insects fulfil the nutritional requirements for the development of the Trichogramma larvae and they are recommended as hosts for Trichogramma propagationThe average number of adult Trichogramma emerging from a single egg of Dendrolimus sp. and that of Attacus cynthia ricini is 27.3 and 28 respectively with the respective maximum reaching 52 and 59 in the present record. If too many adults emerge from a single egg, both their size and reproductive potentiality would decrease and, moreover, the number of the male individuals would increase and the adult life would shorten. Undoubtedly, all these features are unfavourable for the utilization of the parasites for control of the insect pest as far as the effectiveness of the parasites is concerned. From the standpoint of increasing viability of the parasite, regulation of the number of parasites in the egg during the procedure of propagation of Trichogramma is necessary. Regulation of the number of parasites in the egg means regulation of the quantity of the nutrient for the parasites. The method of checking the occurrence of superparasitism is to regulate the ratio of the number of female Trichogramma and host eggs to 1:1 through the procedure of propagation; the period of oviposition should not exceed one day.The quality of nutrient for adult Trichogramma greatly affects its longivity and reproductive potentiality. The result of a nutritional experiment shows that honey is the most suitable nutrient for it. The adults fed with honey have the longivity increased 8.6 times and the number of the offspring 14.7 times as compared with those fed with distilled water.Cold storage effectively reduces the speed of development of the immature stage of Trichogramma. The mature larvae about to pupate within the host eggs maintain their life for 57 days under 4—7℃ and all of them will come out as adults at room tempeature. The fresh eggs of Dendrolimus sp. and of Attacus cynthia ricini kept in cold storage of 0— 4℃ for 97 days and 61 days respectively are still usable for rearing Trichogramma.In order to increase the adaptability of Trichogramma to the environment of the sugarcane field, the rearing procedure is suggested to proceed in the field or in an indoor environment with fluctuating temperature and humidity. The continuous artificial rearing should not exceed five generations before the liberation of the parasites.The distance of dispersion of Trichogramma eva

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。
