We study the influence of γ-ray Irradiation to precipitation of carbon in α-irons by internal friction method. The source is Co~(60). Diameter of specimen is 1.25 mm. Result is that the height of the internal friction peak is decreased by γ-irradiation, and further decreases by annealing at 100℃. after irradiation, but increases at 312℃. Hence we can concluded that the decreasing of height of internal friction peak after irradiation is due to that carbon atoms are attracted to defects of radiation.

In order to test the tactic response of the cotton bollworm, Heliothis ammigera(Hubner), to the odors of its preferred host plant, certain volatile substances known tobe present in the cotton plant such as methanol, trimethylamine and vanillic acid werechosen as olfactory stimulants. It was found that the larvae in the early three instarswere attracted by the vapors of vanillic acid and trimethylamine in various degrees, butmethanol vapor had a repellent effect. These vapors were emitted from aqueous solu-tions at the concentrations of 0.006 M 0.02 M and 0.03 M respectively. By using thesugars, free amino acids and vitamins which were shown to be present in the cotton plantas gustatory stimulants and incorporating them separately in the agar-based media, it wasfound that at the concentration of 0.02 M sucrose and fructose had a definite phago-stimulating effect, glucose was less effective, and xylose was indifferent. At low concen-trations, only DL-alanine among the five amino acids tested had some phago-stimulatingeffect, and ascorbic acid at 0.01 M was phago-inhibitive. These results show that thecotton bollworm as a polyphagous species responds differently to the individual com-ponents of the host plant which may act either as attractants or repellents, phago-stimulants or phago-inhibitors. Different species and varieties of cotton plants and some descendants from thehybridization between cotton and some other malvaceous plants such as Hibiscus palus-tris,H. mutabilis, Malva sylvestris and Althaea rosea were used to test the tactic andfeeding responses of the cotton bollworm. It was found that when the larvae had thechance to choose their food, they were more readily attracted to the leaves of Gossypiumhirsutum and certain variety of G. barbadense, but not so readily to some of the hybriddescendants, some of which may even show repulsive properties in the test. In thisrespect different varieties of H. barbadense also had different effects. When there wasno chance to choose their food, the larvae were observed to consume different quantitiesof foliage from different plants in a definite period of time and to become conditionedto the host plants with which they were brought up. Simultaneous chemical analysis showed that the water content as well as the total andprotein nitrogen contents of the cotton leaves gradually decreased as growth proceeded.The total nitrogen content also dropped when the squares developed into flowers, andthe protein content was found to reach the maximum when the squares had attained alength about 2.5 cm. The total and protein nitrogen contents of the bolls dropped asthe latter grew and aged. The total and protein nitrogen contents of the leaves seemedto be the highest as compared with those of the squares and bolls. The quantities ofsoluble and reducing sugars of the young leaves exceeded those of the tender and oldleaves, but the sugar contents of the bolls were found to be much higher than those ofthe leaves. The sugar contents of the squares were relatively low. In spite of these disparities, it was possible to grow the larvae after hatching into maturity separately andsolely on the leaves, squares and bolls of the cotton plants. In these rearing experi-ments, the cumulative quantities of food consumed, the rates of development and mor-tality, and the weights of pupae thus obtained were found to be conspicuously different.It is interesting to note that the larvae during the whole course of development wouldconsume the old leaves to an amount which may double the total quantity of the foodconsumed when the young leaves were offered. When the bolls were used as food thecumulative quantity consumed exceeded several times that when the leaves were used.This difference is presumably attributed to the differences in the water and sugar con-tents of the different organs of the cotton plant, as already shown that sugars usuallywould evoke a strong phago-stimulating effect. The general impression is that the plantorgans which have the higher sugar and water contents usually have a better nutritiveeff

本工作选用棉花不同器官所含有的几种化学成分作为嗅觉和味觉刺激剂,测验棉铃虫对它们的反应;结果表明一至三龄的幼虫对甲醇三甲基胺、香草酸等的趋性不同,四龄幼虫对不同的糖类、氨基酸等的取食反应也各不一。这说明幼虫对食料植物中的个别化学成分有感觉辨识的能力。用不同品种的海岛棉、陆地棉、以及棉花和其它锦葵科植物杂交所产生的后代的叶片来试验棉铃虫对它们的趋性和取食反应,结果表明当有选择的机会时幼虫对陆地棉和一定品种海岛棉有较强的趋性,对某些杂交后代的趋性很弱。在不能选择的条件下棉铃虫在一定时间内对不同种类或品种的棉叶的取食量也不相同,并对原来的食料植物可形成条件化。 曾对棉花不同器官的含水量、含氮物质和糖类进行了测定,同时分别用叶、蕾和铃将新孵化的幼虫饲养到老熟。幼虫取食不同器官时的累积食量、发育速度、死亡率,和变成的蛹的重量均有明显的差别。当以大叶为食时幼虫的总食量超过以嫩叶为食时的一倍以上;以铃为食时总食量可为以嫩叶为食时的数倍。这种差异可能是因铃中水分和含糖量较高,对幼虫的取食发生强烈的助长作用所造成的。因此,同株植物上含糖和含水缺多的器官对棉铃虫似乎有较好的营养效应,而这种效应可能是通过糖类等的味觉刺激来增加取食...

The first paper of the present series of studies suggested that the armyworm moths,which appeared in early spring in northeastern China, were probably not from local areabut rather coming from a great distance from the south along with the prevailing tradewind. It follows, therefore, that the Gulf of Chili and the Yellow Sea might be thepassing routes of the migrating moths. A team of workers was then organized toobserve the event. The work was started in May, and ended in September 1960. Observers and workerswere carried on board of steamships which ran regularly between coastal cities (Darien,Tientsin, Yientai, Lungkow, Tsingtao, Shanghai) (Fig. 1). There were altogether 113voyages, and regular formulation of attractant was used as a trap placed on the deck of various steamships. Observations of migratory activities of moths began from twi-light to daybreak. Besides these steamships, fishing boats were also engaged to make thesame effort. During the course of the study, visits were also paid to local villagersand older fishermen, collecting as much information as possible. The results of our observation may roughly be summarized as follows: 1. Among 113 voyages, moth immigrants were observed 71 times varying froma few scattered individuals (more often) to several thousand individuals (less often)passing over or flying to our ship (Fig. 2). The frequencies of the appearance of mothsimmigrants were presented on Table 2. On June the 5th. the appearance of moths wasthe most spectacular, not only our workers participated on the capturing, but the chiefpilot, sailors, passengers and other students were also attracted to the sight. As many as214 moths were caught by one person within one hour. 2. The nocturnal activity was quite evident, starting from 17:00, with a peakabout 20:00 and continued to daybreak with another peak at 4:00. 3. The number of moths caught during the period varied from time to time, andthe pattern of appearance could be compared with that of Darien (Fig. 3). The peakappeared in the middle of June and almost disappeared in July, two other peaks fol-lowed, one in the latter part of July and the other in the latter part of August. 4. The directions of flying were analyzed (Fig. 4), but no consistent conclusioncould be drawn. It might be pointed out that more moths appeared when prevailingwinds were from the south. When the wind speed was not high they flew against thewind, otherwise they flew along with the wind. 5. Accompanying the armyworm moths, there were also other insects immigrantssuch as Agrotis, Euxoa, Percnia, Heliothis, Clania and Crocothemis, etc.

根据1959年在哈尔滨粘虫越冬座谈会上,提出粘虫迁飞的假说,同时,根据气流流场的分析,黄、渤海海面将是粘虫在早春由南方往东北迁飞过境的一个地区。于1960年,我们在黄、渤海地区进行了粘虫迁飞的观察。研究人员亲自乘客输在各航线上进行实地观察和捕蛾工作。在全年113航次中就有71航次发现了迁飞的粘虫。有几次出现了大蛾群,徒手即可大量捕捉。与此同时,研究人员还访问了沿海居民和委託水产公司的渔输在出海捕鱼中搜捕粘虫。这些工作亦得到了类似的结果。这为粘虫迁飞的假说,提供了有力的新的证据。 粘虫在海面迁飞动态的观察结果中初步可以看出粘虫在海面迁飞的时期,数量,迁飞的昼夜节律以及粘虫迁飞活动与气象状况的多方面关系。迁飞粘虫的外形和生理状况也作了简述。 本文讨论了有关的几个问题:1.海面迁飞粘虫与东北地区发蛾之间的关系:2.粘虫迁飞的途径与方式:3.粘虫迁飞时期和回迁问题:4.其它迁飞昆虫的问题;5.海面粘虫迁飞与渔汛的关系。
