In order to determine the practical value of the Bordeaux mixture as acontrol measure for the cotton leafhopper, a field experiment was designedand carried out in 1943 at Shatang, Liuchow, Kwangsi. Three known effective contact poisons, namely, a water suspension ofYam bean seed power (Gross Smith value 1%) (1:1000), a water suspension ofpyrethrum powder (1:600), and a water extract of tobacco (Nicotine content2.35%) (1:100) were applied at the same time with two types of Bordeauxmixture (4-6-50 and 2-4-50)...

In order to determine the practical value of the Bordeaux mixture as acontrol measure for the cotton leafhopper, a field experiment was designedand carried out in 1943 at Shatang, Liuchow, Kwangsi. Three known effective contact poisons, namely, a water suspension ofYam bean seed power (Gross Smith value 1%) (1:1000), a water suspension ofpyrethrum powder (1:600), and a water extract of tobacco (Nicotine content2.35%) (1:100) were applied at the same time with two types of Bordeauxmixture (4-6-50 and 2-4-50) for four applications at a fifteen-day intervalduring the early growth season of cotton from June 15 to July 30. The popula-tion of leafhopper, the degree of infestation, the number of green bolls andthe yield of lint cotton were statistically analyzed and discussed. Population observations showed that the three contact poisons greatlyreduced the leafhopper population on the first day after application. Butthey soon lost their effectiveness three days later, so that the population startedto rebuild up and was practically with no significant difference from that ofhe untreated plots at the end of the fifteen-day interval. While the Bordeaux mixture showed a maximum reduction of population on the third day afterapplication, and maintained its effectiveness for a considerable time; the pop-ulation was constantly checked to such an extent that no serious damage wouldoccur during the spray interval. The degree of infestation as indicated by the symptom of cyrtosis onleaves was 40.83, 47.21, 55.85, 57.66, 62.48, and 60.39 per cent in average for4-6-50 Bordeaux mixture, 2-4-50 Bordeaux mixture, yam bean seed powdersuspension, pyrethrum powder suspension and tobacco water extract and theuntreated check plots respectively. Moreover, the percentage of heavily in-fested plants for the treated and untreated plots in the fore-mentioned orderwas 5.61, 8.24, 21.88, 23.68, 28.88 and 25.27 respectively.It was evident thatin the long run the Bordeaux mixture was the most effective insecticide inreducing the degree of infestation. The number of bolls per plant was 15.27, 13.24, 10.17, 9.53, 8.75 and6.75 in average, and the yield of lint cotton was 19.50, 17.84, 11.69, 10.11and 6.24 catties per mou (1 catty=0.5 kilogram, 1 mou=0.164 acre) for thetwo types of Bordeaux mixture and three kinds of contact poisons and theuntreated check plots respectively. The yield of cotton was generally much lower in 1943 than in 1942 forthe same experimental field. This was apparently due to the poorer soilfertility and heavier leafhopper infestation in 1943. But the ratio of the yieldbetween the Bordeaux mixture treated plots and the check plots was quitedifferent in the two years, i.e. 55.62 to 31 catties per mou in 1942, and 19.50to 6.24 catties per mou in 1943. This revealed a fact that the Bordeauxmixture treatment will he applied more effectively and profitably where thecotton field is not fertile and when the leafhopper outbreak is severe. 4-6-50 Bordeaux mixture and 2-4-50 Bordeaux mixture were in all casesinsignificantly different in their effectiveness. Theiefore a 2-4-50 Bordeauxmixture would be a more economical and practical measure for the cottonleafhopper control.

The present paper reports on the results of some preliminary observationson the insect parasites of the pine caterpillar, carried out in the Nanking dis-trict during 1936-37. (1) The following insect parasites were reared from various stages of thepine caterpillar: Egg parasites: Trichogramma evanescens Westwood, Telenomus dendrolimusiChu, Anastatus gastropachae Ashmead. Larva parasites: Casinaria dendrolimi Uchida, Rhogas spectabilis (Matsumura),Stenaraeoides octocinctus (Ashmead), Itoplectis nigribasalis Uchida, Tricholygasorbillans Wied., Sturmia sp., Carcelia sp. Pupal parasites: Xanthopimpla japonica Krieger, Pimpla disparis Viereck,Brachymaria obscurata (Walker), Brachymeria fiskei Crawford. Hyperparasites: Phygadeuon latipatiolator Uchida, Monodontomerus dentipes(Boheman), Brachymeria obscurata (Walker), Brachymeria fishei Crawford, Eury-toma sp. (2) The egg parasites played an important part in the natural control ofthe pine caterpillar. The percentage of parasitism reached 61% in the materialcollected at Tang-shan, 1936. Telenomus dendrolimusi and Anastatus gastropachaewere observed to be more important than Trichogramma evanescens. (3) As high as 26% of the early-instar larvae could be killed by the para-sites. The percentage of larval parasitism and the relative value of the severalparasites varied with the time at which host material was collected. A differ-ence of a few days would give entirely different results. (4) The late-instar larvae were attacked by three species of dipterousparasites. The highest percentage of parasitism observed was 42%. (5) 38.4% of the pine caterpillar were killed during their pre-papal andpupal stage chiefly by Sturmia sp. and Xanthopimpla japonica Krieger. (6) The percentage of parasitism whether in the egg, larva or pupa stagewere observed to be always higher in the second generation than in the first,a fact suggests that hibernation may have an important bearing upon thepopulation of the parasites. (7) The time of appearance of the more important parasites and theirhabits were discussed. (8) Some of the factors, such as hyperparasitism, non-synchronization ofthe life cycles of the host and parasite, over-restriction in host selection, andthe influence of certain control measures, which have adverse effects on theparasite populations, were discussed. (9) As the percentage of parasitisn fluctuated greatly with year and season,it, is, therefore, suggested that a study of the factors which are responsible forthese fluctuations is of primary importance. Based on the results of suchstudies, measures may be adopted to increase the efficiency of the parasites.

Karrer and Enslin reported that the structure of alstyrine (S_(19)H_(22)N_2), a selenium- dehydrogenation-degradation product obtained by Sharp from the alkaloid alstonine, is identical with that of corynanthyrine, α-[2-(4, 5 diethylpyridyl)]-β-ethylindole (Ⅱ), despite the fact that the melting points of these two substances have a 5°difference. In his investigation, the author of the present paper has synthesized two homologues of (II), α-(2-pyridyl)-β- methylindole (Ⅲ) and α-(2-pyridyl)-β-ethylindole (Ⅳ), finding that the former has almost the same ultraviolet absorption spectrum as that of alsyrine and that, like alstyrine, the metho- sulphate of the compounds (Ⅲ) and (Ⅳ) gives the same red colour reaction upon treatment with dilute sodium-hydroxide solution. The Fischer indole synthesis to cyclize the phenylhydrazone of the corresponding alkyl- 2-pyridylketone in the presence of mineral acid was employed by the author in the preparation of compounds (Ⅲ) and (Ⅳ). Besides, three a-carboline derivatives, namely, 2-(cyclohexylmethyl)-β-carboline (Ⅻ), 2-[(4'-methylcyclohexyl)-methyl]-β-carboline (XIII) and 2-[(2'-methylcyclohexyl)-methyl]- β-carboline (XIV), have also been synthesized; none of them is identical with alstyrine in physical and chemical properties. The preparation of compounds (Ⅻ), ((XIII)) and ((XIV)) was carried out according to the method originated by Bischler and Napieralski. This involved the condensation of tryptamine with a suitable acid, or acid chloride, first to form an amide, which was then cyclized with phosphorus pentoxide, and finally dehydrogenated .partially with selenium. The melting points of the two α-(2-pyridyl)-β-alkylindoles, three β-carbolines, their inter- mediates, and a few derivatives of theirs are as follows: ■

1.合成了兩種吲(朶) 衍生物:α-(2-吡啶基)-β-甲基吲(朶) 及α-(2-吡啶基)-β-乙基吲(朶)。前者的紫外線吸收光譜與阿爾斯泰令(alstyrine,係一種由西阿斯木鹼經硒降解後的產物)的吸收光譜極為類似;且二者有一種相同的顏色反應。因此說明阿爾斯泰令的結構可能與可利南斯令(corynanthyrine),α-[2-(4,5-雙乙吡啶基)]-β-乙基吲(朶)相同。 2.合成了三種β-咔卟啉的衍生物:2-環己烷甲基-β-咔卟啉,2-[(4′-甲基環己烷)甲基]-β-咔卟啉及2-[(2′-甲基環已烷)甲基]-β-咔卟啉。這些化合物的化學及物理性質都和阿爾斯泰令不同。因此後者不是β-咔卟啉衍生物。
