The rheological properties of silk solution are important because they strongly affect the spinning performance of the silk solution and the structures of resultant fibrous materials. Therefore, as a preliminary study on the effect of solvent composition on the rheological properties of silk fibroin (SF) solution and structure of the resultant film, in the reported work, methanol was added to the SF formic acid solution. A small amount of methanol (i.e. 2%) added to the SF formic acid solution significantly altered the rheological properties of the solution: its shear viscosity increased by 10 folds at low shear and decreased on increasing the shear rate, demonstrating shear thinning behavior of the SF solution. Dynamic tests for the SF solution indicated that the addition of 2% methanol altered the viscous state of the SF formic acid solution to elastic. However, the molecular conformation (i.e. β-sheet conformation) of the regenerated SF film cast from formic acid remained unchanged on the addition of 2% methanol. © 2020 The Korean Society of Sericultural Sciences Int.

Field experiments were carried out, at Mansoura district, Dakahlia Governorate, Egypt to evaluate the efficiency of di- ammonium phosphate, ammonium carbonate and ammonium acetate in enhancing GF-120, as insecticidal bait, for B. zonata based on their pH level under high and low population levels of B. zonata. Results showed that di-ammonium phosphate enhanced the attractiveness of GF-120 the most, followed by ammonium carbonate and ammonium acetate. Without adding any of the ammonium compounds to the GF-120 bait, the bait attracted the fewest B. zonata flies regardless of population levels. As the concentrations of ammonium compounds increased, the pH-level increased as well in the prepared GF-120 solutions, resulting in increased numbers of B. zonata flies captured. In contrast to males, females of B. zonata were more responsive to increase concentrations of the three ammonium compounds tested. Accordingly, all treatments attracted females more than males. The sex ratio (as number of attracted females per one male) was generally higher under low than high fly population levels.","PeriodicalId":14140,"journal":{"name":"International journal of industrial entomology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91221614","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}
