Climate change is still occurring, manifested in rising temperatures, increased river, and coastal flooding and erosion, rising sea levels, increasing salinity, and more frequent, severe weather events. It is evident that men and women are affected differently by the environmental consequences of climate change. Women become more vulnerable to climate change impacts and environmental disasters. The paper aims to show the interrelationship of climate change, environmental security, and gender in Bangladesh. Moreover, the paper examines the impacts of climate change in environmental security from the gender perspective exploring the condition of women during disasters and their vulnerabilities under climate change scenarios in Bangladesh. Secondary data have been used and analyzed to identify the overall condition of women during hazardous situations in Bangladesh. Available data reveal that a number of climate-induced hazards are already affecting many women especially in the coastal zone, low-lying areas, and northwest part of the country. The paper finds that climate change has disproportionate impacts on women in Bangladesh affecting their food security, water security, health security, economic livelihood as well as internal migration. Finally, the paper provides policy recommendations dealing with the gender-differentiated climate change vulnerabilities experienced by Bangladesh.","PeriodicalId":106651,"journal":{"name":"Journal of Knowledge Learning and Science Technology ISSN: 2959-6386 (online)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131802629","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}

The present study addresses the effect of photoperiod of H.Hebetor reared on the host C. cephalonica. The results revealed that the effect of photoperiod of H. hebetor reared host in C. cepholonica was not significantly varied. The highest percentage of parasitism (98.553%) was recorded in 08L:16D followed by 91.110% in 24L:00D photoperiod. 86.667% in 00L:24D respectively. However the photoperiod 12L:12D showed the lowest percentage 82.223% of parasitism. The highest percent of pupae formed and adult emergence of parasitoid H. hebetor was achieved (98.045%) for 00L: 24D and (98.923%) for 08L:16D photoperiod when reared on C.cephalonica. The highest number of larval production (86.33) was recorded for 00L:24 photoperiod and lowest was 20.67 for 12L:12D photoperiod. The result showed the highest adult male and female body, head width and wing span length in 08L:16D photoperiod when reared on the host C. cepholonica.","PeriodicalId":106651,"journal":{"name":"Journal of Knowledge Learning and Science Technology ISSN: 2959-6386 (online)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251732","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}
