Studies on the effect of Catharanthus roseus alkaloids on the biology of Euproctis fratema showed that at a dose of 10 ppm, only 19.25% fertile eggs were laid. The hatchability was totally suppressed at higher doses. There was a considerable reduction in total carbohydrate and protein content in treated larvae. The activity of digestive enzymes were also found to be inhibited.
Entomopathogenic fungi Beauveria bassiana is being used as a biopesticide for various insect pests. Many field level usages were started long back but when it comes to the storage level the usage were minimized. In order to minimize the usage of synthetic chemical pesticide and to improve the biopesticide the present study was undertaken to control the stored product pest Corcyra cephalonica as it is the primary pest which causes economical agriculture loss to our country. B. bassiana secretes enzymes like amylase, protease, chitinase and lipase. These enzymes act on the protein present in the insect pests and bring death to the insect. These were verified by in silico docking studies and the enzyme amylase was found to be the best docking ligand.
The present study is mainly based on the field work conducted from 2008-2013 to different parts of North East India. Altogether collected 13 species of Tectaria from North East India are presented along with identification key, descriptions and photos for easy identification. All the collected species have been deposited at Botanical Survey of India, Arunachal Pradesh Regional Centre, Itanagar (ARUN).
this study aims to determine the relationship between peer groups and the hedonic lifestyle of students. This research method uses quantitative research with the object of Class XI students. The population in this study was 148 students of Class XI and the number of samples was 108 students. The data analysis technique used is Pearson product moment correlation analysis. The data collection tool used in this study was a questionnaire or questionnaire. The Pearson product moment correlation coefficient generated in this study of 0.216 illustrates that there is a relationship with a low category between peer groups and the hedonic lifestyle of students. The Pearson product moment correlation value is greater than the rtable value of 0.189 so that Ho is rejected and Ha is accepted. The conclusion of this study is that there is a significant unidirectional relationship between peer groups and the hedonic lifestyle of students.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
