Results showed that the food consumption rate and assimilation rate were greatest for larvae fed on tender and over matured mulberry leaves as compared to larvae fed on mature leaves. Assimilation and conversion efficiencies were very high in the larvae grown on matured mulberry leaves (0.189 and 1.99% respectively). Moreover, the larvae fed on matured mulberry leaves showed higher growth rate, cocoon weight and shell ratio. Among the three different growth stages of leaves, the matured leaves were found to be the best food for final instar larvae of Bombyx mori L. which promotes maximum larval growth and it gains to quality cocoon and raw silk production.","PeriodicalId":87603,"journal":{"name":"Entomon; internationale Zeitschrift fur die gesamte Insektenkunde","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83634040","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}

Studies were conducted to assess the compatibility of systemic insecticide, carbosulfan 25 EC with a fungicide, micronutrient and insecticide in brinjal ecosystem. The optimum and effective dose of carbosulfan (250 g a.i.ha-1) was compatible with other agro chemicals used in combination viz., copper oxy chloride 50 WP @500 g a.i.ha-1, zinc sulphate 0.5 per cent and dimethoate 30 EC @ 300 g a.i.ha-1, without any creaming matter and/or sediment formation in any of the combinations. The tank mix foliar application of the combination chemicals viz., carbosulfan @ 250 g a.i.ha-1 + copper oxy chloride 50 WP @ 500 g a.i.ha-1, carbosulfan @ 250 g a.i.ha-1 + zinc sulphate 0.5 per cent and carbosulfan @ 250 g a.i.ha-1 + dimethoate @ 300 g a.i.ha-1 did not inflict any phytotoxic effect on the treatment imposed plants and a mean grade of ‘1’ (0-10% injury) was awarded to all the treated plants in the brinjal ecosystem. The bioefficacy trials after two rounds of spraying with carbosulfan and combination with fertilizer and fungicides revealed that maximum per cent reduction is noticed in insecticide combination (carbosulfan @ 250 g a.i.ha-1 + dimethoate @ 300 g a.i.ha-1) as well as recommended and four times the dose of carbosulfan (250 and 1000 g a.i.ha-1), which similarly effects in managing the shoot and fruit damage caused by the shoot and fruit borer, Leucinodes orbonalis. The treatments with fertilizer and fungicides alone marked the least reduction in fruit and shoot damage. The yield of brinjal ranged from 24.1to 28.7 t ha-1 in different treatments. Plots treated with carbosulfan @ 250 g a.i.ha-1 + dimethoate @ 300 g a.i.ha-1recorded the highest fruit yield (28.7 t ha-1) followed by carbosulfan @ 250 g a.i.ha-1 + copper oxy chloride @ 500 g a.i.ha-1 (28.3 t ha-1) and carbosulfan @ 250 g a.i.ha-1+ zinc sulphate (27.8 t ha-1).

Of the total 11 species that belong to 4 genera collected during the study, the standardized belt transect protocol recorded only two genera and 5 species in 20 hours of sampling effort, while the simplified protocol with half the effort (10 hours) recorded two genera and 4 species. Random search method with least effort (6h) recorded 4 genera and 11 species that included all the species collected in the earlier methods. There was a marked difference in sampling efficiency; the random sampling method yielded 1.87 species per hour while standardized belt transect protocol and simplified belt transect protocol yielded only 0.25 and 0.4 species per hour respectively. The result of the study was further verified in three more habitats viz. natural forest, coffee plantation and tea plantation which gave similar results. The study indicates that the random search method which covers more area in less time yield more representative termite fauna in all the four habitats tested, than the standardized belt transect protocol which spends more time covering less area.","PeriodicalId":87603,"journal":{"name":"Entomon; internationale Zeitschrift fur die gesamte Insektenkunde","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88780112","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 new taxon, Purana cheeveeda Sadasivan sp. nov. is easily differentiated from all the other known species of the Purana tigrina species group based on its operculum apex not reaching beyond the anterior margin of sternite 3; tubercles on sternite 4 black and almost as large as those on sternite 3; relatively short rostral length reaching unction of abdominal sternite II and sternite III; the absence of dark fasciae on the transverse grooves of postclypeus, forewing venation, basal lobes of pygofer with large diverging triangular spines and the characteristic pentagonal uncus of the male. The status of Purana tigrina (Walker, 1850) from South India is discussed. The topotypes of the taxon commonly identified as P. tigrina from south India did not match the morphology of the holotype of P. tigrina. In addition, the study of the type specimen of P. tigrina demonstrated that the external morphology and male genital characters of the holotype of P. tigrina match that of P. tigrina from the Malayan region. Hence the type locality is mislabelled. This common taxon from southern India which has been traditionally misidentified is described here as a new species of Purana. As per Articles 76A.1.4 and 76A.2, of the International Code of Zoological Nomenclature (1999), the type locality of P. tigrina is hereby corrected as Malaysia. Based on the findings, P. tigrina is removed from the south Indian cicada fauna. The new species has some features common to both the Purana carmente group and Purana tigrina group, but most characters agree to Purana tigrina group, hence is tentatively placed in this group. The characters based on coloration may not be useful in species group classification in Purana, hence structural features like male genitalia and venation are taken to revise the existing species group keys. A modified key to the Purana species groups and members of the P. tigrina species group is also provided.","PeriodicalId":87603,"journal":{"name":"Entomon; internationale Zeitschrift fur die gesamte Insektenkunde","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80569499","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}
