The rice stem borer, Chilo Simplex Butler causes great damage to therice crop in the medium semi-glutinous rice region, long water rice region,and late semi-glutinous rice region in Kiangsu. Rice stem borer has two generations a year. The first generation is mostabundant between mid-and late July. The second generation is most abundantin mid-late August. In 1952 and 1953, the borer had had reached and suchabundance cave in the middle of September, that a third incomplete generationseemed probable. Experimental result shows that late sowing and late transplanting of riceminimized borer damage.

The present paper reports on the results of some preliminary observationson the insect parasites of the pine caterpillar, carried out in the Nanking dis-trict during 1936-37. (1) The following insect parasites were reared from various stages of thepine caterpillar: Egg parasites: Trichogramma evanescens Westwood, Telenomus dendrolimusiChu, Anastatus gastropachae Ashmead. Larva parasites: Casinaria dendrolimi Uchida, Rhogas spectabilis (Matsumura),Stenaraeoides octocinctus (Ashmead), Itoplectis nigribasalis Uchida,...

The present paper reports on the results of some preliminary observationson the insect parasites of the pine caterpillar, carried out in the Nanking dis-trict during 1936-37. (1) The following insect parasites were reared from various stages of thepine caterpillar: Egg parasites: Trichogramma evanescens Westwood, Telenomus dendrolimusiChu, Anastatus gastropachae Ashmead. Larva parasites: Casinaria dendrolimi Uchida, Rhogas spectabilis (Matsumura),Stenaraeoides octocinctus (Ashmead), Itoplectis nigribasalis Uchida, Tricholygasorbillans Wied., Sturmia sp., Carcelia sp. Pupal parasites: Xanthopimpla japonica Krieger, Pimpla disparis Viereck,Brachymaria obscurata (Walker), Brachymeria fiskei Crawford. Hyperparasites: Phygadeuon latipatiolator Uchida, Monodontomerus dentipes(Boheman), Brachymeria obscurata (Walker), Brachymeria fishei Crawford, Eury-toma sp. (2) The egg parasites played an important part in the natural control ofthe pine caterpillar. The percentage of parasitism reached 61% in the materialcollected at Tang-shan, 1936. Telenomus dendrolimusi and Anastatus gastropachaewere observed to be more important than Trichogramma evanescens. (3) As high as 26% of the early-instar larvae could be killed by the para-sites. The percentage of larval parasitism and the relative value of the severalparasites varied with the time at which host material was collected. A differ-ence of a few days would give entirely different results. (4) The late-instar larvae were attacked by three species of dipterousparasites. The highest percentage of parasitism observed was 42%. (5) 38.4% of the pine caterpillar were killed during their pre-papal andpupal stage chiefly by Sturmia sp. and Xanthopimpla japonica Krieger. (6) The percentage of parasitism whether in the egg, larva or pupa stagewere observed to be always higher in the second generation than in the first,a fact suggests that hibernation may have an important bearing upon thepopulation of the parasites. (7) The time of appearance of the more important parasites and theirhabits were discussed. (8) Some of the factors, such as hyperparasitism, non-synchronization ofthe life cycles of the host and parasite, over-restriction in host selection, andthe influence of certain control measures, which have adverse effects on theparasite populations, were discussed. (9) As the percentage of parasitisn fluctuated greatly with year and season,it, is, therefore, suggested that a study of the factors which are responsible forthese fluctuations is of primary importance. Based on the results of suchstudies, measures may be adopted to increase the efficiency of the parasites.

1936—37年在南京地区观察松毛虫寄生天敌所得的初步结果可简述如下: (一)南京地区业经发现的松毛虫天敌有卵寄生蜂3种:赤眼卵蜂、松毛虫长腹卵蜂、平腹小蜂;幼虫寄生蜂4种:松毛虫瘦姬蜂、松与虫红头小茧蜂、花胸姬蜂、黑基瘤姬蜂;幼虫寄生蝇3种:家蚕寄生蝇、大寄生蝇、小寄生蝇;蛹寄生蜂4种;日本黑点姬蜂、黑瘤姬蜂、大腿蜂、费氏大腿蜂;另重寄生8种。 (二)卵寄生蜂在防治松毛虫上起了适当大的作用,有时减低寄主虫口达61.24%。3种寄生蜂中以松与虫长腹卵蜂及平腹小峰为较重要。 (三)松毛虫初龄幼虫寄生率最高时可达26%。寄生率的高低及各种天敌的比较重要性与采集寄主材料的时期有密切的关系,往往数日之差,寄生率可截然不同。 (四)松与虫的后龄幼虫遭3种寄生蝇的寄生。寄生率最高可达42%。 (五)松毛虫茧期的寄生率可达38.4%,天敌中以大寄生蝇及日本黑点姬蜂为 最主要。 (六)无论在卵期、幼虫期或蛹期,第2化松毛虫的寄生率均比第1化的为高。此点似说明越冬问题是松毛虫天敌繁殖中的一个关系问题。 (七)几种比较重要的寄生天敌的发生时期和生活习性,本文中根据观察所及,加以记载。 (八)本文中将几个影...

From February 1954 to February 1955, we have continuously studied the morphological changes of the reproductive glands of the Oncomelaniid snails once monthly by dissecting and serial sectioning. The snails used for this study, measuring within the range of 7.1 to 3.0mm., were collected from the banks of Ching-San River, Chungking, Kiangsu.The results of this study show that the reproductive glands of the Oncomelaniid snails, either male or female, exhibit periodic changes with hypertrophic and atro-phic phases...

From February 1954 to February 1955, we have continuously studied the morphological changes of the reproductive glands of the Oncomelaniid snails once monthly by dissecting and serial sectioning. The snails used for this study, measuring within the range of 7.1 to 3.0mm., were collected from the banks of Ching-San River, Chungking, Kiangsu.The results of this study show that the reproductive glands of the Oncomelaniid snails, either male or female, exhibit periodic changes with hypertrophic and atro-phic phases alternating with each other.From November to May of the following year, the ovary of the female snail is in the phase of hypertrophy. It is large, thick and prominent, containing a large number of eggs in the different stages of development. In June, some of the ovaries become smaller and thinner. From July to August, the ovary enters the atrophic phase, diminishing remarkably in size and containing only a small number of the primary oocytes. Beginning from September, the ovary shows signs of recovery and in October resumes its egg-producing capacity.From experimental and field observations, the female Oncomelaniid snails lay eggs from November to July of the following year, laying a large amount of eggs being laid from February to June, but no eggs at all from August to October. These findings are in agreement with the periodic changes of the ovary as shown above.The periodic changes of the testis, involving both hypertrophic or atrophic phases, appear about 4 months earliec than those of the ovary. From January to April, the testis appears atrophied, but in the vas deferens a large amount of spermatozoa is stored up. From May to August, the testis recovers gradually, being capable of producing spermatozoa, and from September to November it enlarges greatly, producing a large amount of spermatozoa. In December the testis again inclines to atrophy.From the field study, we know that the copulation of the Oncomelaniid snails takes place throughout the year, but more often during spring and autumn. Microscopic sections show that spermatozoa are found present in vasa deferentia every month, and in a greater amount in winter, spring and autumn. This would assure the fertilization of the eggs during the main copulation season.

从1954年2月到1955年2月,我们每月应用外形解剖结合组织切片的方法,观察了日本血吸虫中间宿主——钉螺生殖腺的周期变化。 雌螺卵巢在一年内有一度的周期变化。从11月到第二年5月,卵巢呈丰满而多卵的状态;6月卵巢趋向萎缩;7、8月卵巢萎缩,内仅含有少量的幼稚卵细胞;9月卵巢开始趋向丰满;10月卵巢逐渐恢复丰满的状态。卵巢全年周期变化的过程与镇江地区钉螺的产卵情况基本上相符合。 雄螺精巢在一年内也有一度的周期变化,但较卵巢要提早4个月左右。1—4月精巢呈萎缩状态,但输精管中尚储存有大量精子。5—8月精巢逐渐恢复原状,能产生少量精子,此时输精管中的精子还少。9—11月精巢特别丰满,含有大量精子。12月精巢开始萎缩。在9月以后,输精管中即逐渐储满了精子。输精管内精子储存的情况与南京及杭州地区钉螺的交配情况基本上相符合。
