A comprehensive search was conducted using the Scopus database with keywords related to Tasar silkworm. A total of 741 relevant articles were identified and analyzed using VOSviewer, Bibliometrix, and Biblioshiny in R to examine statistical patterns. Over the decades, research focus has transitioned from fundamental silk characterization to biomedical applications, including tissue engineering, biodegradation studies, and antioxidant properties. Publication trends indicate peak research activity between 2007 and 2010, followed by a decline post-2018, likely due to shifting priorities toward commercially dominant silkworm species. Indian institutions have been the primary contributors, reflecting strong domestic expertise, while global collaborations remain limited. Keyword analysis highlights the growing interdisciplinary nature of Tasar silk research, extending into biomaterials and sustainable technology. Future research directions emphasize biotechnological advancements, biomedical applications, eco-friendly processing, climate resilience, and commercialization strategies. Strengthening international collaborations and integrating innovative technologies will be crucial for advancing Tasar silk research in both scientific and industrial domains.</p>","PeriodicalId":517424,"journal":{"name":"Frontiers in insect science","volume":"5 ","pages":"1533267"},"PeriodicalIF":2.4,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075178/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although predators have the same probability of attacking winged and wingless morphs in natural conditions, an increment in the proportion of winged morphs dispersed under predation risk may have a negative effect on predator feeding by reducing the size of the wingless form available on the plant. However, the wingless aphids may be richer in nutritional value than the dispersed winged aphids. Therefore, the nutritional consequences of aphid morphs and egg cannibalism for development, survival, 10-clutch fecundity and fertility, and the time needed for 10 clutches of eggs <i>Chrysoperla carnea</i> were addressed via a series of experiments. Wingless aphids accelerated the total development and increased the survival of <i>C. carnea</i> compared to the winged aphids. Furthermore, feeding with the wingless form increased the 10-clutch fecundities and fertilities, and reduced the days needed for 10 clutches of eggs. Neonate larvae of <i>C. carnea</i> that devoured two conspecific eggs took a shorter time with an acceleration in the overall development of <i>C. carnea</i>. Immature mortality was higher in controls than in the cannibalism treatment. Reproductive benefits were obvious in females permitted to consume two conspecific eggs during their first instar compared to those that did not. However, the time needed for 10 ovipositions did not differ between both groups. These findings are ecologically significant because <i>C. carnea</i> females are able to adapt to the stresses imposed by nature without needing winged aphid prey to distribute their eggs widely, as their larvae can grow on their own eggs and gain developmental and reproductive benefits from such behavior when prey availability or quality is low.</p>","PeriodicalId":517424,"journal":{"name":"Frontiers in insect science","volume":"5 ","pages":"1562606"},"PeriodicalIF":2.4,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12053061/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144061467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As generalist predators with a wide range of insect-based diets, it is crucial to identify suitable prey options, especially for restricted environments such as terrariums, which are limited compared to the wild. This study investigates the use of adult black soldier flies (BSF; <i>Hermetia illucens;</i> Linnaeus, 1758) as a sole food source for two mantis species, <i>Chlidonoptera lestoni</i> (Roy & Leston, 1975) and <i>Hierodula patellifera</i> (Serville, 1839), while assessing their suitability and potential challenges associated with their digestion. The BSF is widely recognized for its high nutritional value and ease of rearing, making it an attractive prey candidate for mantises. Although natural capture behavior and high feed acceptance have been observed, adult BSF seem not to be suitable as sole feed for both mantises. Our results suggest that imbalances in macronutrients, particularly the protein/fat ratio, may contribute to high mortality. The use of BSF as a mono-diet could also limit access to a variety of beneficial microorganisms that are essential for maintaining a healthy gut microbiota in mantises, thereby affecting their immunity and well-being in captivity. In addition, the possible presence of pathogenic microorganisms in the BSF could also have affected the mantises' survival.
