Tin's paper deals with the effects of some dietary physico-chemical factors on the feeding and growth of the silkworm. Some dietary requirements for the growth of the larvae have been studied and clarified. The results are as follows.1.Our experiments showed that chlorogenic acid, morin arid inositol promoted the feeding activity of the newly hatched larvae. β-Sitosterol and gallic acid were important for the normal growth of early instar larvae and chlorogenie acid, morin and inostiol also showed some favourable...

Tin's paper deals with the effects of some dietary physico-chemical factors on the feeding and growth of the silkworm. Some dietary requirements for the growth of the larvae have been studied and clarified. The results are as follows.1.Our experiments showed that chlorogenic acid, morin arid inositol promoted the feeding activity of the newly hatched larvae. β-Sitosterol and gallic acid were important for the normal growth of early instar larvae and chlorogenie acid, morin and inostiol also showed some favourable effects on that stage. In contrast, the above mentioned chemicals had very slight influence on the fifth instar larvae. In our experiments we did not find the feeding promotive effect of β-sitosterol on the newly hatched larvae.2.There were feeding repellent factors in the ether extracts of the soya-bean cake powder, and a water soluble factor may be removed by treatment with 90% me-thanol. The methanol treated powder favoured the growth of the early instar larvae. The feeding repellent effect of the untreated cake powder was less conspicuous on the later instar larvae. Better results on larva rearing were obtained when sorbie acid was used as the antiseptic agent in the artificial diet in comparison with that when propionic acid was used.3.The optimal water contents in the artificial diets for the newly hatched larvae, early instar larvae and later instar larvae were 77%, 73% and 71% respectively. Our experiments also showed that the results of larva rearing were influenced by the gel forming agents which contributed much to the physical character of the diets.4.Suitable regulation of the dietary acidity to pH 5 with citric acid and ascorbic acid favoured both the larval feeding activity and the rearing results.5.Based on the facts that the responses to the feeding promotive and repellent factors in the diets were different in different larval instars, it seems necessary to design different artificial diets for the larvae of different developmental stages: the newly hatched larvae, first to fourth instar larvae and the fifth instar larvae. There was also a difference in the different varieties of the silkworm to adapt the artificial diets which demonstrated the difference in their requirements for the physico-chemical factors in the diets.

本文研究了人工饲料某些理化因素对蚕儿摄食和生长的影响,从而阐明家蚕生长发育过程中在摄食行为和营养上的特点和变化。 1.试验表明:绿原酸、桑色素、肌醇可增进蚁蚕摄食:β-谷固醇、没食子酸对保证小蚕正常发育甚为重要,绿原酸、桑色素、肌醇也有良好影响;相比之下,上述一些因子对5龄大蚕的作用较小。此外未看到β-谷固醇对蚁蚕的摄食促进效果。 2.大豆粉的醚溶性成份中,含有影响蚁蚕摄食的忌避物质。大豆粉经90%甲醇处理,可以除去某种水溶性因子,有利小蚕生长;对比之下,上列因素对大蚕的损害较小。比较了二种常见防腐剂对家蚕摄食、成长的影响:山梨酸的饲蚕成绩优于丙酸。 3.在本试验基本组成条件下,收蚁、小蚕、大蚕所用饲料的含水率分别以77%、73%、71%左右为宜。实验说明,蚕儿饲育效果还受饲料中具有成形作用组份的影响。 4.调查了饲料pH和蚕儿摄食、成长的关系:以某些适宜的有机酸(如柠檬酸、抗坏血酸)调节饲料的pH在5左右为好。 5.由于不同发育阶段的蚕儿对摄食、成长促进因子的感受性和对忌避因素的耐受性均不相同,从而提出,对蚕儿作全龄饲育,至少应分别设计为收蚁用、1—4龄小蚕用、5龄大蚕用三种饲料。此外,不同品种家蚕对人工饲...

The antifeeding and repellent effects of the materials obtained from neem(Azadirachta indica) and two species of chinaberry(Melia toosendan and M. azedarach) were evaluated in the laboratory to some insect pest.s by bioassay. The preliminary results showed that Meliaceus plants may be taken as potential insecticides as antifeedants or repellents. Against the third instar larvae of Prodenia litura, all the samples tested had very strong antifeeding effects and gave above 90% inhibition of feeding. The ethanol extract of the seed kernels of M.azedaraeh at a concentration of 5% gave 99.8% inhibition of feeding on the larvae of the small rice noctuid (Spodoptera abyssina), neem oil also showed marked activity but the samples of M. toosendan were less effective. To the fifth instar of the white-veined rice armyworm (Leucania compta), 2% neem oil and petroleum ether extract of seed kernel of M. toosendan showed high feeding inhibitory effects. All samples tested showed strong deterrent activities to the citrus aphis (Aphis citricidis) , but Less effective to another aphis (Toxoptera aurantii) .The adults of two species of June beetles showed special feeding reactions to all samples tested,against Anomala cupripes , the neem oil and the ethanol extract of the seed kernel of M .azedarach had strong antifeeding activities, but the petroleum ether extract of the seed kernel of M. azedarach attracted the beetles to feed more leaves.Neem oil showed antifeeding activity at a concentration of 3% to the beetles, Holotrichia ovata,but at a concentration of 1.4%, a very marked attraction to feeding was observed.Our studies indicated that the reactions of insects to antifeedants were very complex,further experiments are needed to evalute the mode of action of toxic principles obtained from Meliaceus plants.

本文报道了楝科植物(印楝、川楝、苦楝)杀虫剂对几种害虫的拒食、忌避作用室内的测定结果。用叶碟法测定了对三种夜蛾幼虫的拒食作用,结果表明,各种供试样品对斜纹夜蛾3龄幼虫均表现出强烈的拒食活性。5%苦楝种核乙醇提取物对小水稻叶夜蛾5龄幼虫拒食率高达99.8%。2%印楝油对白脉粘虫5龄幼虫拒食率达92%。用枝条选择着落法测定了对柑桔蚜虫的忌避作用,供试的楝科植物样本对桔蚜均表现出强的活性,但对桔二叉蚜则较差。苦楝种核乙醇提取物和印楝油对红脚异丽金龟(虫甲)有拒食作用,但苦楝种核石油醚提取物却表现出明显的引诱取食活性。3%的印楝油对卵圆鳃金龟(虫甲)表现出拒食作用,但1.4%的浓度却刺激此虫大量取食,苦楝种核粉石油醚提取物对此虫又有强的拒食活性。这可进一步说明昆虫对拒食剂表现出复杂的取食和行为反应。
