The injurious insects of cotton of this province, however, have not hithertobeen carefully studied, especially the pink bollworm, which annually reducesthe cotton production by 10 to 30 per cent. The present authors spent twoyears in observing the life history and habits of this insect, in attempting tofind some effective control measures. The result is herewith summarized :- 1. In the vicinity of Wu-chang, the pink bollworm has three generationsa year. The first generation occupies May and July. The second one occursin mid-July and the last in late-August. Due to the lower temperature, theemergence of the first generation need about two months. 2. In day time, the adult is usually inactive, while in windless night,after seven o'clock, it becomes very active and lays eggs mostly on green bollsand calyx. about a week later, the eggs hatch and the newly-hatched larvaeare shortly getting into the bolls. After four days they often eat into theseeds. Ten days later, the lint is so stunted as to become dusky yellow incolor, thus both the yield and the quality of cotton are greatly lowered. Themature larvae appear about half a month after. 3. Field experiments have shown that three dustings of 10% DDT- sulfurpowder were very effective. In the severely damaged cotton area, the thirdspray may be simultaneously done with controlling the cotton leaf-hoppers andthe cotton leaf-rollers. 4. About 84% hibernating larvae in cotton seeds will come out when thecotton exposed in sun light and stored in the farmer's house. Hence it seemsadvisable to put cloth or other soft material covers on the cotton stored inorder to collect and kill the larvae under them. In addition, destruction of allremaining bolls on the cotton stalks, as early as possible in winter is important. 5. For controlling the bollworms in cotton store-houses, the followingresults have been obtained 50% wettable DDT diluted with 20 parts of water,91% of larvae were killed within 30 days; 6.5% 666 (benzene hexachloride)gave a mortality of 63% in four months. Wettable 6.5% 666 diluted withwater (1:100), has been proved to be the most effective ovicide which destroys99.4% of eggs while parathion (E605) also gave a very high mortality at97.7%. But 50% wettable DDT (1:100) Kills eggs at 64.2% and lead arsena-te only 16.2% respectively. 6. There were 39.1% overwintering larvae parasitized by parasitic mitesand wasps. Among them, most are the mite, Pediculoides ventricosus Newport,while the parasitic wasps Eurypterna arakawae Mats. less than 0.5%.

红铃虫在南方棉区为害棉花相当严重,除去脱落蕾铃外,僵黄花率为10—30%,我们针对这个严重问题,进行了红铃虫生活史的观察研究与防治方法试验,写出初步结果,提供防治参考。 1.红铃虫在华中武昌棉区一年有三代。第一代羽化在5至6月,7月中旬为第二代;8月下旬为第三代;第一代的蛹和幼虫所需时期均较第二、三代长。 2.成虫白天不活动,夜晚7时以后无风天气活跃最盛,产卵以在青铃上及花萼上为最多。孵化后三十多分钟即钻入棉桃内为害,4天即侵入棉籽内取食,10天棉瓤纤维呈僵黄状,半月后幼虫即可老熟(第三代的)。 3.田间防治红铃虫以10%滴滴涕硫磺粉喷三次效果显著,在后期棉虫严重地区可结合防治叶跳虫卷叶虫等同时进行。 4.籽花内的幼虫在群众家里及晒花时逃出84%,因此指导群众将籽花堆上加覆盖物,再结合帘架晒花是消减过冬红铃虫最经济有效的办法。 4.防治仓库越冬红铃虫以50%可混性滴滴涕1:30倍水溶液杀虫效果最佳。30天内死亡率达91%.6.5%可混性666(1:20)死亡率为63%。但是1:100倍的水溶液杀卵效率高到99.4%。稀释万分之一的E605为97.7%。50%可混性滴滴涕1:100杀卵率为64.2%,砒酸铃最差...

A new method is proposed in this paper for the evaluation of the following three important kinds of three-center and four-center integrals needed in molecular quantum mechanics: (1) (2) (3) Obviously, integral (2) is a special case of integral (3), so we need only to evaluate the first and the third. The following equations have been obtained for the evaluation of the above-mentioned two kinds of integrals (4) (5) where (6) (7) (8) (9) R_0 in equation (4) is the distance of point a apart from the origin located in bc line, while that in equation (5) is the distance between the two chosen origins separately located in ab and cd lines. θ_0 is the angle made byand, and θ_(10), θ_(20) and θ_(12) are respectively the angles made by and,and,and, The fourth term of equation (5) is, in general, negligible except in the case of R_0, which is less than two Bohr units. We propose two methods for the evaluation of and : the first one is to choose the origin at the end-point of the bond and evaluate the integral strictly inside and outside the sphere of radius, while the second one is to choose the origin at the mid-point of the bond and evaluate its value inside and outside the ellipsoid passing through the end-point of. The calculation involved in the second method is quite simple and, of course, a small error is introduced in changing the region of integration from the sphere to the ellipsoid, but it is quite negligible in comparison with the result of our first method. Equation (4) is exact in all cases, while equation (5) is exact in many cases but also involves certain errors in some other cases. From our actual calculations, we draw the conclusion that equation (5) is almost exact in the evaluation of integrals L_(aa, bc) and L_(ab, cd) and that certain error is involved in the evaluation of integral L_(ab, bc), but the error introduced does not exceed ten per cent.

在本篇文章中,我們建議了一種新方法來計算量子力學中的三中心和四中心積分;這方法此以往的好,因為計算簡單,應用廣闊,結果也比較可靠。我們用來計算三中心吸引能的公式[方程(5)]是在任何情况下都是正確的,而用來計算三中心和四中心的排斥能積分公式[方程(18)]在某些情况下是正確的,在另一些情况却能引進一些誤差。在計算非相隣鍵的積分時引進的誤差很小,可以忽略不計;在計算相隣鍵的積分時引進的誤差此較大,但不超過百分之十。我們建議兩種計算A_u和B_u的方法,一種方法是以鍵的一個端點爲原點,嚴格按照球內外的區域積分;另一種方法是以鍵的中點為原點,按照橢圓體的內外區域積分。前一種方法理論上嚴密,然而後一種方法計算簡單,收斂性快,引進的誤差也不大;尤其在計算相隣鍵的三中心排斥能的積分時,似乎後一方法得到的結果還比前一方法好。在本文中,為了容易說明起見,常常引用吸引能和排斥能這兩個名詞,實際我們的方法,是用來計算下列三類積分:它們不僅包括吸引能和排斥能積分,也把交换積分包括在內,甚至可以在更廣泛的意義上看待上列積分。若σ_1,σ_2也是Φ_1和Φ_2的函數時,仍可以用我們的一般展開理論處理,不過要此本文複雜。

Rapana pecheliensis,being amongst the largest rachigloseans found on the north coast of our country,is of high value in fishery.Tehang-Si described the general features aud the form of egg capsule of this snail in 1936 and 1955 respectively,but its life history so far is known,has escaped investi- gation.The present paper is to report the reproduction and embryonic development of this animal and tends to give a closer comparison in these respects between it and other rachiglossans ever studied.In the past four years,in addition to the trac ment of cell lineage and of morphogenetic process of embryonic stages data bearing upon the breeding season,sexual activities and spawning habit were collected.The breeding season of R.pecheliensis,like that of its sister species,R.thornasiana,lasted from the begining of June almost to the middle of August.Nevertheless this period eeemed to be affected by changes of temperature.During spawning,groups of eggs,after being fertilized one after another in a chamber just posterior to the pallial oviduct,were extruded into the latter where they became encapsulated.In the whole lumen of this duct of a female with her shell over 7.6 m.m.in height,usually no lees than two to three capsules being in formation might be found at a time,the larger and more complete one being nearer to its exit.Examinations of new-laid capsules did not reveal nurse eggs which had been found in other rachiglossans such as Purpura,Buccinum and Fasiolaria.All eggs within a capsule began to segment after the capsule was laid at temperature ranging from 21.0° to 26.5℃.The shape of blastomeres together with yolk lobe resulting from the first cleavage or the second one and the relation of cleavage plans in the later stage appeared identical completely with that of R.thomasiana,Nassa mutabilie and N.reticulatus,bnt somewhat different from that of Purpura lapillus,though in later stages of cleavage all these snails expressed an uniformity specially in the pattern of arrangement of blastomeres.Tbe presence of the yolk lobe in the first cleavage of R.pecheliensis had resulted in the formation of a trefoil btage which was very similar to that occured in the development of Ilyanassa and Dentalium.The only difference between them lies in the manner of movement by which the yolk lobe was formed.In R.pechelieusis,the yolk lobe appeared as soon as the blastomeres AB and CD were constricted off from its animal pole,while in the other two,this structure came off entirely from the vegetal pole of the egg.As cleavage proceeded a blastoderm cap came into view and when it covered three seventh of the surface of the yolk cell 4D epibolic gastrulation took place.Before the closing of the blaetopore the endoderm cells 4A.4B.and 4C.divided repeatedly to form the ventral lip of the pore.This and the delay of their becoming invested by the ectoderm cells showed that the cleavage of R.pechelienc-is was in some degree alike a meroblastic type,mostly due to the concentrating up of the yolk into 4D.Within the capsule embryos passed through a veliger stage.It was about four to five weeks from the time the ova were laid until the fully formed veligers escaped from the capsule.The organogenesis in the veliger stage of R.pecheliensis closely resembled that of Nassa reticulatus.During or just after hatching the rudiments of the osphradium,gill filaments,and heart had not yet appeared,to say nothing of that of sexual organs.
