        Earias cupreoviridis Walker is one of the serious pests of field cotton in Hunan.This paper deals with the results obtained in1959, 1960 and 1961 in Tar-tong Lake ofHunan province. Five generations were recorded in the laboratory and also observed inthe cotton field in 1961. Earliest appearance of the moth in cotton field was in late June, but larvae in fieldwere abundant from early July to late August (third to fourth generation). The last gene-ration larvae occurred in November from which pupae were produced within the cottonplant to pass the winter. The longevity of the moth was 4.9--11.5 days. The durationof egg stage was 3--10.1 days. The larvae passed 6 instars and larval stage lasted10.5--23.3 days. The pupal period of the first four generations was around one to twoweeks. The larvae did not remain in one boll or bud but bore out again and crawl frombud to bud or boll to boll. Other habits of adult, larvae and pupa are described. The sequence of outbreak of this pest were also investigated. In general, larval po-pulation increased when average five-day temperature was between 26--30℃. andaverage humidity over 80%, or coefficient of temperature and humidity between 2.7--3.3.On the other hand, population decreases when the average five-day temperature wasover 30℃. and the coefficient of temperature and humidity below 2.7. When the plantswere dense,the percentages of infection were different. The names of varieties of cottonunder observation were given.

        Field and laboratory investigations on the overwintering forms of five species ofaphids, the cotton aphid, Aphis gossypii Glover, the English grain aphid, Macrosiphumgrandrium (Kirby), the turnip aphid, Rhopalosiphum pseudobrassicae (Davis), the greenpeach aphid, Myzus persicae (Sulzer), and the black citrus aphid, Toxoptera aurantii(Fonsc.) were carried out during 1955--1962 in Chungking, Szechuan. Under natural conditions, the cotton aphids lay overwintering eggs on certain de-ciduous woody plants, such as the cotton-rose, Hibiscus mutabilis L., and the shrubbyalthaea, Hibiscus syriacus L. This species, however, will remain in parthenogenetic formsthoroughout the winter season on the herbaceous plant, such as the hollyhock, Althaearosea (L.). The English grain aphid, the turnip aphid and the black citrus aphid gene-rally continue their parthenogenetic generations in winter on their particular host plants.It seems more complicate in the case of the green aphid, those bred on winter growingvegetable crops, such as the various species of crucifers, the lettuce and spinach, usuallyreproduce asexually in winter; but a few sexuparae, sexual females and males may alsoappear on peach leaves. As the sexual females would not lay any overwintering eggwithout mating, and the males usually appear later on peach tree than the sexual females,hence the females are usually incapable of laying eggs before the falling of the peachleaves. Under experimental conditions, when the turnip aphid bred on old yellowing leavesof unhealthy plants of rape at a certain low temperature would produce a few sexualfemales and eggs, but no sexual male was observed. Some results were obtained fromfield investigations on the Chinese cabbage. The English grain aphid when bred arti-ficially on ears of wheat plants, which were sown early in August and reached headingand milky stage early in winter, produced a few males, but no sexual female or eggwas observed. Insectary breeding tests proved that inoculation of the cotton aphids ontohollyhock from field cotton, cotton-rose and shrubby althaea produced parthenogeneticoffspring; when the cotton aphids inoculated onto shrubby althaea twigs, cultured intap water, produced sexual offspring. These results were quite similar to those obtainunder natural conditions. The writer considers that the temperature, the photoperiod and the kinds and growthconditions of host plants will bring a combined effect on the reproduction of sexualforms in aphids, but the effect will be various in different species. Therefore, in thesame locality, different species of aphids may have different overwintering forms becauseof their different reactions to the environmental factors. Moreover, in one districtwhere the environmental conditions are fundamentally alike, under a definite low tem-perature, a species of aphid may either reproduce parthenogenetically or produce sexualforms in winter, depending essentially upon the different nutrient conditions in the dietobtainable by the species from its host plants.

        Four different types of cytoplasmic male sterility in maize were tested for their identityby use of the restoration technique.Male-sterile lines incorporated with cytoplasm of theTexas source were found to be completely affected in crosses by a group of restorers includ-ing W153,W28 and G32,and partially restored by W24,M14 and A34.This made a figure of6 restorers out of about 60 inbreds thus tested in the Texas cytoplasm.Inbreds W153 wasselected as a differential restorer for T-type steriles since it gave no reactions to the othertypes.For the Moldavia type of male sterility,formerly offered by Prof.Hadjinov,we founda partially restoring inbred W9 to be better suited for the similar purpose.The third andfourth type of male sterility,designated as B- and G-type,came through our own selectionsfrom two Bulgarian varieties.Separation between them seemed difficult.Since A374 gavepartial pollen fertility to the B-type steriles exclusively,it could be used as a differentiat orfor this type of cytoplasm.Pollen restoration in crosses involving W153 and W28 followed the expectation based ona dominant Mendelian gene.However,data obtained from segregating progenies of doublecrosses in which G32 was the restorer suggested strongly that two dominant complementarygenes were more workable.The difference in genotype of inbreds concerned in variousinvestigations seemed to be responsible for such inconsistent results.Segregating patterns in the Texas sterile crosses of the partial restorer,W24 or M14,varied with plants used as the pollen parent and with the date of planting.It appeared verylikely that W24 and M14 were heterozygous for major restorer genes since one sterile versionof W24 and four fully restoring lines of M14 had been established by conversion and test-cross-ing respectively.Dominant modifiers might also be present in either of the inbred popula-tions.In the presence of Moldavian cytoplasm the recessive allele of the restorer gene seemedto exert an abortive action to its pollen carriers produced by the heterozygote.When plantsheterozygous for the restorer gone were outcrossed to male steriles carrying the right cyto-plasm,all plants from the progenies proved to be pollen shedders.It was suggested that theM-type cytoplasm might be similar to that of S-type.Tentative genotypes related to pollen restoration of Texas male sterility had been workedout for a number of inbreds on the basis of two dominant complementary genes.Workingschemes for the production of double-cross seeds of maize without detasseling had been sum-marized and discussed by the authers.

        三種細胞質遺傳的玉米雄花不孕類型各有其專效的恢復系和部分恢復系。在 T 型細胞質基礎上,測定出兩對顯性互補基因決定著花粉孕育性的恢復,同時還有顯性修飾基因存在,影響其表現的程度。春播和夏播的不同環境條件只對部分恢復性的表現發生明顯影響,對全恢復性和不孕性則很少能夠改變。M 型恢復性的等位隱性基因在雜合株內對花粉粒具有某種致死或敗育作用,故測交后代表現不分離現象。本文初步鑒定了若干常用自交系的 T 型恢復基因型,并以此作為根據,提出了配制全不去雄的玉米雙交種的各種可能方案。
