Identification of high temperature tolerant bivoltine breeds by screening for thermotolerance in the silkworm, Bombyx mori (Lepidoptera: Bombycidae) is an essential prerequisite for the development of thermotolerant bivoltine breeds / hybrids. Therefore, in this study, 20 silkworm breeds were reared at different temperatures (25 ± 1°C,32 ± 1°C, 34 ± 1°C and 36 ± 1°C) for 6 h every day from 3 rd d of th instar to till spinning. Significant differences ( p < 0.01) were found among all the rearing traits over temperature. Based on pupation percentage, SK4C and BHR3 were identified as thermotolerant bivoltine breeds. Hierarchical clustering analysis based on rearing traits at tested temperatures grouped 20 silkworm breeds in four clusters which included one cluster each of susceptible and tolerant, and two clusters of moderately tolerant silkworm breeds. This suggests that clustering based on rearing data at high temperatures by using Euclidean distance can be an effective approach in classifying the silkworm breeds on their thermotolerance capacity. The identified breeds would be used for development of thermo tolerant bivoltine silkworm breeds / hybrids.","PeriodicalId":14140,"journal":{"name":"International journal of industrial entomology","volume":"19 1","pages":"115-126"},"PeriodicalIF":0.0,"publicationDate":"2015-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72994323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we identify and characterize one of these peptides, Scolopendrasin I. We identified the centipede antimicrobial peptide Cecropin from the centipede transcriptome using an SVM algorithm, and subsequently analyzed the amino acid sequence for predicted secondary structure using a GOR algorithm. We identified an alpha helical region of Cecropin and named it Scolopendrasin I. We then assessed antimicrobial and hemolytic activity of Scolopendrasin I. Scolopendrasin I showed antimicrobial activity against various microbes, including antibiotic-resistant Gram-negative bacteria, in a radial diffusion assay. Scolopendrasin I had potent antibacterial activity against acne-associated microbes in a colony count assay and showed no hemolytic activity in a hemolysis assay. In addition, we confirmed that Scolopendrasin I bound to the surface of bacteria via a specific interaction with lipoteichoic acid and lipopolysaccharide, two components of bacterial cell membranes. In conclusion, the results presented here provide evidence that this is an efficient strategy for antimicrobial peptide candidate identification and that Scolopendrasin I has potential for successful antibiotic development.","PeriodicalId":14140,"journal":{"name":"International journal of industrial entomology","volume":"14 1","pages":"14-19"},"PeriodicalIF":0.0,"publicationDate":"2015-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76089647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this insect is economically important and is commercially reared and sold in Korea. Recently, P. brevitarsis was listed as a temporal food ingredient by the Korean Ministry of Food and Drug Safety. Given the increasing economic importance of this beetle, we have sought to improve rearing conditions for its commercial production. In this study, we compared the effects of two food supplements, clay and charcoal, on the growth of second instar larvae of P. brevitarsis . Clay and charcoal are generally known as good adsorbent for removal of contaminating substances in insect feed. We fed second instar P. brevitarsis larvae a commercial diet consisting of fermented sawdust with seven different combinations of clay and/or activated charcoal, and measured their effects on weight gain for approximately 17 wk until larvae pupated. We found that addition of clay at 2.5% w/w of the fermented sawdust diet had no negative effect on weight gain of second instar P. brevitarsis larvae and thus may improve the quality of P. brevitarsis as a commercial food.","PeriodicalId":14140,"journal":{"name":"International journal of industrial entomology","volume":"2800 1","pages":"25-29"},"PeriodicalIF":0.0,"publicationDate":"2015-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86496933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected from those who visited the special insect exhibition in May 2013 using a self-reporting survey. The results indicated that 48.3% of the responders had experienced insect rearing, and that rhino and stag beetles were the most commonly reared insects. Most of the respondents (83.1%) reported they were not currently rearing any insects, which suggested that insect rearing tends to be a one-time experience. Expected psychological effects could be divided into emotional (56.3%) and cognitive (41.8%) effects, and these varied by age and gender. The differences in expected psychological effects were particularly clear between adults and adolescents, the latter of whom were the main participants in the activity. It is therefore necessary to develop standardized manuals and care programs for more diverse insect species with which to help keep up consumer interest in educational insect rearing. These efforts will help champion the psychotherapeutic effects of educational pet insect rearing and enhance its role as a learning aid.","PeriodicalId":14140,"journal":{"name":"International journal of industrial entomology","volume":"416 1","pages":"7-13"},"PeriodicalIF":0.0,"publicationDate":"2015-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75254006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
