A new species of tapeworm Bothriocephalus gowkongensis sp. nov. is reported for Ctenopharyngodon idellus from Gowkong, near Canton, South China. The parasite is of great economic importance owing to the high mortality of the host caused by the infection and consequently heavy losses to the freshwater fishery industry. A preliminary note is given on the life cycle, which involves unidentified cyclops as intermediate hosts. The eggs are fully embryonated when laid and it is the first Bothriocephalus konwn with this phenomenon. From a study of the variation in a large number of specimens of B. gowkongensis sp. nov., the author considers B. opsariichthydis Yamaguti, 1934 a synonym of B. achilognathi Yamaguti, 1934.SPECIFIC DIAGNOSIS: Bothriocephalus Rudolphi, 1808 emended Lühe, 1899, with generic characters. About 35-80 mm. in length and 0.5-1.2 mm. in width. Segments with or without distinct segmentation. Slight indications of secondary segmentation might occur in all segments. Immature segments broader than long, mature segments square and gravid segments longer than broad. Scolex large, fleshy, heart-shaped with distinct terminal disc and well-developed fleshy bothria. Inner longitudinal muscle bundles extremely weak and sparsely scattered. 50-90 testes. Cirrus immediately in front of vagina. Cirro-vaginal aperture median or slightly lateral between mid-line and posterior third of segment. Ovary near posterior of proglottid. Uterus convoluted, voluminous, and confined to median field. Uterine sac-may encroach on posterior border of preceeding segment or be placed some distance away. Vitellaria in complete circle in cortex. Like the testes, they are continuous from segment to segment. Eggs thin-shelled, operculated, fully embryonated when laid, measuring 33-38 53-54μType host: Ctenopharyngodon idellus.Habitat: Intestine.Type: To be deposited with the Department of Parasitology, Hun-Nan Medical College, Canton, China.Co-types: In author's collection, and to be deposited with the Depertment of Biology, Chung-Shan University, Canton, China.

1.文中记载草鱼腸中新种絛蟲B. gowkongensisn. sp. 是由广东九江採得的。 2.本蟲促使宿主的死亡率,使淡水渔业受到很大的损失。 3.由头槽絛蟲生活史的初步观察,发现它的卵排出时,已有发育完全的胚胎。 4.从研究大量新种标本的变化中,作者认为B. opsariichthydis Yamaguti, 1934是B. achilognathi Yamaguti, 1934的同种异名。

Ericerus pela Chavannes, the insect producing white wax,belongs to Coccidae,Homoptera. The female adult lays eggs while the male larva produces wax, whichis a well-known product from Southwest China. The wax secreted by the malelarvae may be boiled and extracted to result in something known as white wax.Its boiling point reaches above 82-83℃. It has manifold uses. Before WorldWar Ⅱ, besides the consumption at home, th greater part of this product wasexported abroad. The supply of the female adults of this wax insect in the wax-producing districtusually appears short annually, due to a peculiarity in the growth of this creature;and therefore naturally exist two correlative districts, that is a district of adultproduction and one of wax production. As these two.districts are located morethan 500 kilometres apart,every year the female adults ready to be transplantedon he feeding trees in the district of wax production have to be supplied bythe district of adult production, and they must be carried over a long distance.The carriage of the female adults of the wax insect from one place to theother has been practiced for about five hundred years by the people engaged inwax production. This article reports on a test of transportation of the female adults of the wax insect from Paikuowan (白菓湾) in Hweili County (会理县), formerly of SikangProvince to Huhtaokou (核桃沟) in Omei County (峨眉县), Szechwan Province.Investigations in this connection were made from the April 30 to May 13, 1941. It has long been the aim of the growers to produce the female adults of theinsect and the wax in the same locality. With this realized, the area of wax pro-duction would be enlarged, and the quantity of wax increased. However, as the female adults of the insect in the distr .ct of wax produc-tion are subject to such natural adversities as geographical features, temperatureand humidity, parasitic enemies etc., up to the present they cannot be raised andsapplied insufficient quantity in this district. For this reason, to in prove themethod of transporting the adults female insects to the wax-producing district, toShorten the time on the way,and to increase the vitality of the male larvae-all these have become the crucial questions in the promotion of wax production. The principal explanation, knowh for centuries, with regard to the impossi-bility to raise the female adults of the insects in the district of wax productionhas been the peculiar fact that the female larvae could not be carried in quickorder to a place over 500 kilometres apart. The present test has proved that al-though the female larvae were, in the greater part, hatched out on the way, therewere still a part of them reaching the destination in safety. Valuable informat-ion was also obtained on the hatching rate of the male and female larvae on theway, the influence of environmental factors on the sex ratio, the different speciesof parasitic enemies, etc.. It is hoped thet the facts thus ascertained will be ofservice to improving the methods of wax production.

白蜡虫是我国的特产,古代农民远在元朝已有饲养。在过去全国的白蜡年产量约在五万至十万担间,据1918年重庆海关报告有一万一千余担,值银七十七万余海 关两。解放前一、二十年来,由于国民党反动派的不重视和摧残,已逐渐衰落。白蜡是化学工业上的重要原料,用途很广,饲养蜡虫又是西南各省农民的主要副业,而且农民群众已积累了非常丰富的传统经验。因此,为了总结群众经验,发扬科学遗产,改进饲养技术,振兴蜡业,我们希望能引起有关方面的注意和进一步研究,除研究改进白蜡虫的经管技术外,又须注意白蜡在工业上的用途。 白蜡虫的种蜡异地繁荣,在目前已成为自然的形势,而蜡区种虫不能自给,是白蜡业发展上的基本障碍。我们通过本次测验之后,认为我国适于蜡虫(雄虫)繁育的地方很多,如四川、湖南、浙江、安徽、福建、江西、江苏等丘陵地带都可扑虫产蜡,关键问题在于改善运种方法。在目前我国交通运输业已有普遍发展的基础上,只要用航空运种即可在短时间内将种虫运送至全国蜡区。扩大蜡区,增加农民副业收入,发扬我国科学遗产,为国家创造财富,利用益虫为生产服务,在目前已完全有实现的可能。
