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

The inner harbor of Amoy possesses three different types of sea-shore, namely rocky, sandy and sand-muddy shores. The vertical distribution of organisms on the rocky shore agrees cssentially with the Vaillant principle for the classification of littoral zones, whilst the vertical distribution of organisms on the sandy and sand-muddy shotes is closely related to the composition of substratum.According to the mean biomass of whole year, the order of magnitude of the three different shores is as follows: rocky shorc(511.5g/M~2)>sand-muddy(40.6g/M~2)>sandy shore(39.7 g/M~2). The rocky shore is dominated by sessile organisms such as algae, bryozoans, barnacles (Balanus amphitrie albicostatus), and oysters(Ostrea cucullata), whilst the sandy and sandmuddy shores are dominated by gastropods, brachyurans and polychaete worms.The total number of species identified in the present investigation amounts to 401, of which 26 belong to plants, 361 to Invertebrata, and 11 to Pisces. The majority of them are. tropical and subtropical species.The combined utilization of sea-shore involves the rational use of wild economic species (e. g,, Ishigo okamutai, Phymosoma scolopus)on the one hand, and the full utilization of each tidal zone on the other hand. The latter aims at developing the littoral culture.The process of adaptation of organissms to the marine and terrestrial environment is best shown in the vertical distribution of organisms on the sea-shore. The zonal distribution of organisms on the rocky'shore and the mosaic distribution of organisms on the sandy and sand-muddy shores appear to be related to the nature of species and the physical conditions of the substratum.

厦门内港具有岩岸、沙岸及泥沙岸等不同类型的潮间带,前者生物的垂直分布交替基本上符合瓦揚对潮间带的分区原则,后两者生物的垂直分布则和底质成份有密切的联系。 按生物量的周年平均值大小,这三种海岸排列如下:岩岸(511.5克/米~2)>泥沙岸(40.6克/米~2)>沙岸(39.7克/米~2),岩相中以(?)牡(?)、白绞藤(?)、藻类和苔(?)虫等固着生物为主,泥沙岸及沙岸以腹足类、短尾类及环虫类为主。 在初步鑑定的401种生物中,植物占29种,无脊椎动物占361种,鱼类占11种,这些大多是热带及亚热带种属。 综合利用潮间带,应全理利用野生资源(如铁钉菜、星虫等)同;时应利用潮间带各个潮区,大力发展海塗养殖事业,本文对这两方面提出了初步意见。 潮间带生物的垂直分布反映了水生生物对陆生生活不同程度的适应,岩相生物的分(?)现象,以及泥沙岸生物的镶嵌分布现象反映了生物本性与无机环境及有机环境有着错什的规律性的联系。

1. Woolly apple aphis infests the apple and causes considerable injuries to the trees in China.In this paper the writers report on the results of the investigations, carried out in 1953-56, onthe bionomics and the utilization of Aphelinus mali, especially on the ways of increasing itsvitality by means of hybridization. 2. Aphelinus mali overwinters in the full-grown larval stage within hardened body of itshost at Tsingtao, Shantung Province. Low temperature, the absolute low temperature there reach-ed as low as --12℃. in 1954 caused litlle winter mortality of the parasite in Tsingtao and thepercentage of the emergence of adult was as high as 85% as usual. The pupae appeared in thelate part of March of the next spring as the temperature of the ten-day average reached 6°to7℃. The first adult from overwintering materials emerged in the middle of April as the tem-perature of ten-day average reathed 11℃. The lowest temperature at which the adults emergedfrom the overwintering larvae kept under the various temperatures was about 10°±1℃. whichwas lower than the figure given by other authors, for example 12°-- 13℃. as reported by Borgin Sweden. 3. There are about 10--12 generations annually, 13 generations in maximum and 9 genera-tions in minimum. The duration of life-cycle of the parasite varies from the different periodsand the main influencing factor is the temperature during the development period of the parasites.One of the longest generation is the overwintering generation which lasts 184 days. Whereas theshortest one lasts about 7 days only in the middle part of August. The optimal temperatures forits development are between 22°to 27℃.; the most favorable humidity range is from 80 to90 per cent. Both are higher than that required by the woolly apple aphis for outbreaks, vtz.16.5°to 22℃. and 60 to 70 per cent. 4. Aphelinus mali had been reported by other authors as parasitizing about twenty differentkinds of aphids, but in Tsingtao it parasitizes mainly the woolly apple aphis in field conditionand just a few of them parasitize in the woolly aphis on Populus canadensis. The female adultsseem to prefer to oviposit in those aphids which have a layer of while wax and are sluggish inmovement, and therefore not only with possess black color as mentioned in the literatures. The adults survived longest in the laboratory (up to 41 days) with access to molasses. Thesex ratio was variable, though females were always more numerous than males, the unfertilisedfemales giving rise to males only. 5. The number of egg-laying by single female adult varies with different temperatures. Thereseems to be more egg-laying in the reasonable high temperature, such as in 1954, the numberof egg-laying per female at the different room temperature is as follows: at 16.3℃., 19℃.,23.3℃., 24.2℃. and 26℃. are 10, 17, 32.4, 58.5 and 21.eggs, respectively; and in 1955 at 19℃.,21℃., 24.3℃., 26.2℃. and 28.4℃.,are 22.7, 29, 44.5, 51 and 28 eggs, respectively. However, the relative humidity seems not so significant as the temperature, but under the high tempera-ture and high humidity condition the adult died more quickly and depoisited less eggs thanusual. The different size of the individual also shows its different number of egg-laying and thebigger one always lay more than the smaller. In Tsingtao, an individaul female deposits amaximum of 108 eggs under laboratory conditions. 6. In Tsingtao region, the parasite have difficulty to get full control of the host pestthroughout the whole season. This is thought to be due to three causes: (1). the low repro-ductive capacity of the local parasite, and especially the adverse effect of low temperature in bothspring and autumn restricted the activity of egg-laying of the adult parasite and the developmentof larval parasite. And in contrast to the host, the pest fares very well under these conditions. (2).the parasite emerges too early in the spring before the woolly apple aphis has become abundant.(3). a large part of the adult parasites died because of shortage of host for oviposition in thespr
