Effect of Temperature and Relative Humidity on Development and Survival of Angoumois Grain Moth, Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) on Stored Maize

The effects of different rearing temperatures (26oC, 30oC, 32oC and 35oC) and of different relative humidities (55, 65, 70 and 85 per cent) on the development and survival of Angoumois grain moths, Sitotroga cerealella (Olive.) were investigated on maize under laboratory conditions during the period from May 2013 to January 2014. Temperature was the main factor affecting egg incubation period, larval-pupal development time, and adult survivorship. The highest number of eggs was laid at 30oC (172.50/female). The shortest incubation period occurred at temperatures of 32oC and higher, but they increased sharply as temperature decreased. Larval-pupal development time was shortest at 30oC. Survivorship was optimal at 30-32oC, but decreased sharply at 26 and 35oC. Male longevity was significantly more (7.17 days) at 2

Duodenal lymphangitis carcinomatosa: A rare case

AbstractDuodenal lymphangitis carcinomatosa has been sporadically described, and little attention has been paid so far. To our knowledge, no data on radiological findings for this rare entity has been published. We report a case of duodenal lymphangitis carcinomatosa secondary to gallbladder mass in a 44-year-old Indian man to focus on the radiological diagnosis, which was further confirmed by endoscopic-guided biopsy and immunohistochemical analysis

The short-horned grasshoppers (Acrididae and Pyrgomorphidae: Orthoptera) of Karnataka, India: A checklist and distribution data

Short-horned grasshoppers’ checklist is presented here. In the present study, the inventory was created using data from a survey conducted in various districts of Karnataka between 2019-2021, including Chikkamagaluru, Dakshina Kannada, Davanagere, Hassan, Kodagu, Shivamogga, Udupi, Uttar Kannada and orthopteran collections at the Insect Systematics Laboratory, Department of Entomology, KSNUAHS, Shivamogga and literature published to date from various parts of Karnataka. A total of 101 species/subspecies belonging to 66 genera, 15 subfamilies and two families i.e., Acrididae and Pyrgomorphidae were reported. Several species were recorded for the first time from the districts investigated, including 9 in Chikkamagaluru, 4 in Dakshina Kannada, 1 each in Hassan and Kodagu, 3 in Shivamogga, 9 in Udupi and 1 in Uttar Kannada. This is the first-ever checklist featuring distribution records for short-horned grasshoppers in Karnataka and is updated with the Orthoptera species file online. The index may help for future taxonomic diversity studies of grasshoppers of Karnatak

Gut microbial degradation of organophosphate insecticides-induces glucose intolerance via gluconeogenesis

International audienceBACKGROUND:Organophosphates are the most frequently and largely applied insecticide in the world due to their biodegradable nature. Gut microbes were shown to degrade organophosphates and cause intestinal dysfunction. The diabetogenic nature of organophosphates was recently reported but the underlying molecular mechanism is unclear. We aimed to understand the role of gut microbiota in organophosphate-induced hyperglycemia and to unravel the molecular mechanism behind this process.RESULTS:Here we demonstrate a high prevalence of diabetes among people directly exposed to organophosphates in rural India (n = 3080). Correlation and linear regression analysis reveal a strong association between plasma organophosphate residues and HbA1c but no association with acetylcholine esterase was noticed. Chronic treatment of mice with organophosphate for 180 days confirms the induction of glucose intolerance with no significant change in acetylcholine esterase. Further fecal transplantation and culture transplantation experiments confirm the involvement of gut microbiota in organophosphate-induced glucose intolerance. Intestinal metatranscriptomic and host metabolomic analyses reveal that gut microbial organophosphate degradation produces short chain fatty acids like acetic acid, which induces gluconeogenesis and thereby accounts for glucose intolerance. Plasma organophosphate residues are positively correlated with fecal esterase activity and acetate level of human diabetes.CONCLUSION:Collectively, our results implicate gluconeogenesis as the key mechanism behind organophosphate-induced hyperglycemia, mediated by the organophosphate-degrading potential of gut microbiota. This study reveals the gut microbiome-mediated diabetogenic nature of organophosphates and hence that the usage of these insecticides should be reconsidered
