In China, Cufex uitattriorhynchus has a wide distribution. It has been found that this mosquito serves as n vector of Japanese B encephalitis inside as well as outside of the country. Virus of Japanese B encephalitis has been isolated repeatedly from this mosquito. It has been demonstrated, furthermore, that this mosquito might be infected by being fed an emulsion of infected mouse brain. Young mice bitten by this mosquito infected with the virus developed symptoms typical of encephalitis.Ecological studies were carried out on this mosquito in Changsha, Hunan from May to October, 1957, with observations upon: (1) the duration from the moment of feeding to emergence of adults of next generation under laboratory conditions, (2) the (.cology of the larva in its natural habitats, and (3) the seasonal distribution of the mosquito.I. The laboratory temperature was maintained from 23?to 28癈 throughout the whole course of observation. Both day and night men were assigned to watch at the working spot to take notes. The results obtained are as follows: 1. In order to ascertain the exact time of feeding, fifty-nine mosquitoes were carefully observed to determine the time necessary for blood sucking on a cow. The shortest time from the outset of inserting the proboscis irito the skin of the cow to the moment of pulling off the pro-boscis was 2 minutes and 26 stconds, while the longest time was 7 minutes and 15 seconds with an average of 3 minutes and 19.2±19.8 seconds.2. Forty-three well-fed mosquitoes were chosen for oviposition, They were kept separately in glass chimneys (5.7 × 9.0 cm.), each of which was slightly immersed in a glass plate. Only 21 mosquitoes (48.84%) laid eggs. They performed their laying quietly on the surface of water. The average time for egg to mature within the ovary was 73.76± 2.06 hours. The lowest number of eggs laid was 15, while the highest number was 238, with an average of 124.43± 13.04 eggs per mosquito.3. The egg raft containing 238 eggs was used for rearing in the laboratory. All the eggs hatched simultaneously after 35 hours of incubation.4. Larvae of the same instar were bred in an enamelled green pan containing hay infusion which was changed daily. On the surface of hay infusion a film of bread powder mixed with yeast was sprinkled. Right arter each moulting, larvae were removed to another enamelled pan. Dead larvae were discarded as soon as discovered. The time needed from the first instar to the end of fourth instar averaged 144.09 hours, i.e., 6 day's and 0.09 hours (Table 1).5. It took. 38.83 hours in average to complete the pupal stage (Table 1).6. It took 291.92 hours or 12 days and 3.92 hours on an average from the time of feeding to the end of metamorphosis, and about 9 days from the time of egg deposition.7. The ratio 'between emergent males and females was 75 to 70, or 51.7% to 48.3% respectively.8. In rearing, the highest mortality occurred in the second stadium,, in which 70 larvae died, 29,4% of total number of larvae.9. Points in connection with biting, behavior and discrepancy in the time of oviposition, ecdysis among different instars, pupation and emergence were discussed.Ⅱ. For field observation on the ecology of larvae of Culex tritaeniorhynchus, eleven types of natural breeding places with a total of fifty localities situated in the suburbs of Changsha were selected. They included rice-fields, tare-fields, lettuce-fields, ipomoea-fields, lotus-roots-fields, trapa ponds, wells for drinking and pits for washing purposes, ponds, ditches and mountain caves with water. The first six types of habitats were definitely devoted to agricultural cultivation, while the latter five were not. Collecting in each of fifty localities was made once a week. In each habitat the collector made five dips by a conical dipper (9.7 cm) at random, took notes on the water temperature, height of the water column where larvae were found, brought back the plants.which grew in association with the larvae and a sufficient amount of water for the determination of hydrogen-ion concentration and dissol

1.本文报告了1957年春,实验室中三带喙库蚊血液消化、产卵、孵化、幼虫的各龄、蛹化、羽化等的初步观察结果。 2.同年5—10月,又初步观察了三带喙库蚊幼虫11型孳生地的十项自然环境因素。 3.自然界的十项环境因素,对此蚊幼虫孳生的影响,亦略加分析讨论。 4.通过11型幼虫孳生地的调查,得知此蚊幼虫多孳生在茭瓜田、蕹菜田、芋头田、稻田及藕田等5型中。 5.1957年三带喙库蚊幼虫全期最高峰的出现日期,与流行性乙型脑炎流行的最高峰恰相吻合。

Aedes albopictus is one of the mosquitoes most often seen in Foochow, but itsecology is not entirely known. Therefore, I have spent a whole year in observing itsecology. The results of my observations are as follows: 1. Aedes albopictus is active in the day time. It is not easy to collect, but theyoften appear in the mosquito net, kitchen, pig sty, drawing-room and among weeds inthe fields.

The results of my observations are as follows: 1. Aedes albopictus is active in the day time. It is not easy to collect, but theyoften appear in the mosquito net, kitchen, pig sty, drawing-room and among weeds inthe fields. The seasonal distribution of Aedes albopictus covers a period from Marchto December with the highest peak in July, August and September. 2. The daily activity of adult Aedes albopictus show two peaks outdoors, one inthe morning at 5--6 o'clock, and one in the late afternoon at 4--5 o'clock. Indoors,only a single peak, at about 1--5 p.m. 3. The breeding places of the larvae are widely distributed, consisting of small re-ceptacles like vats, cans, urns, etc., with water which is always of a light brownish col-our and with rotten leaves and silt at the bottom. The pH values of the water oftypical breeding places is 6.5--7.6, and the total organic nitrogen is 6--20 p.p.m. 4. The larvae of Aedes albopictus are found in most cases to breed alone, and arerarely found together with those of other insects. 5. The egg of Aedes albopictus hibernate for two months and a half in wintertrom middle of December to end of February. 6. The importance of Aedes albopictus in the transmission of Japanese B encephalitis virus is discussed.

Making use of a dichroic filter type anomaloscope,the ratio and the range of vatiation of red to green light in matching for yellow were Studied in 220 sub jectS(146 males,74 females) with no acquired diseases of COlour vision. of the 220 cases,207 are normal. The statistical properties of the distribution of their R/G ratios were analyzed,assuming a normal distribution.The rest,13 cases, constituting a total of 6% COlour defectives of the sample, consist of 3 protans,3 deutans,1 protanomal,2 deuteranomals and 4 extreme deuteranomals. The relative spectral sensitivity cur、vewas determined for 6 of the 7 anomalous trichromats and also for 5 normals. 2 protansand 2 deutans for the purpose of comparison. As an additional qualitative test,the ability of all subjects to tead the pseudo-isOChromatic plates (Ishihara,15 ed.) was also noted. on the basis of a correlated consideration of the present expental findings, the ways by which anomalous trichromatism might come into being were discussed in light of the prpoposal of Roshton regarding the cone pigment trans fomation from normal to dichromats. In order to account for certain behaviour of anomalous trichromats. it has been argued that,in addition to those types inVOlving a pigment transformation,as inthe case of dichromats,of only a proportion of the cell population,some cases probablyinVOlVC an abnormal formation of certain Digments which are not present in either the"red" or the "gteen" system. This abnormal pigment probably represents a certain inter mediate between that of P_(54) and (2P_(54)+3P_(59),thus accounting for a preferential settingof R/G ratio to certain values. In those cases of anomalous trichromat with little or noeviation of the mean value Of R/G ratio from normal but with mederately enlargedatching range,it is likcly that both the "red" and the "green" systems are affected tosome extent so as to make their spectral sensitivity curves approximately equal Therere,besides,even more complicated cases. The 6 anomalous trichromats are thus eterogenous group, DrObably reouiring different explanation for different cases.

利用滤光片型测异仪,对220名(男146,女74)受试者进行了比配黄光所需的红光和绿光的相对量及其变动范围的测定。220例中,207例色觉正常,对他们R/G比值的统计学特性加以分析,假设其分布是正态的。其余13例,占总检查人数的6%,包括甲型色盲3人,乙型色盲3人,甲型异常三色觉者1人,乙型异常三色觉者2人和极端乙型异常三色觉者4人。7名异常三色觉者中的6名的相对光谱亮度曲线曾群加测定。此外,我们还测定了5名正常人,2名甲型色盲和2名乙型色盲的相对光谱亮度曲线,以资此较。同时,所有的受试者还阅读了假等色图谱(Ishihara 15版),作为一种衡量其色分辨能力的定性检查。从我们实验结果的相关考虑,同时根据Rushton对圆锥细胞色素从正常人的分布过渡到二色觉者的分布的建议,对异常三色觉的形成原因进行了探讨。为了解释异常三色觉者的某些视功能表现,除了由一个系统一部分细胞的视色素轉变到另一个系统的视色素而产生的异常三色觉之外,另外一些例子可能是由于形成某些异常的色素而引起的,这种异常的色素既不存在于正常“红”系统中,也不存在于正常“绿”系统中,可能是P_(54)和(...
