Development and validation of forensically useful growth models for Central European population of Creophilus maxillosus L. (Coleoptera: Staphylinidae)
AbstractThe hairy rove beetle,Creophilus maxillosus (Linnaeus) (Staphylinidae), is recognized for its use in forensic entomology. However, insufficient developmental data exist for the Central European population of this species. Accordingly, we studied the development ofC. maxillosus at ten constant temperatures (10 –32.5 °C). Based on these results, linear and nonlinear developmental models were created and validated. We also studied the effect of different homogenous diets (third-instar larvae or puparia ofCalliphora sp. Robineau-Desvoidy orLucilia sp. Robineau-Desvoidy (Diptera: Calliphoridae) or mix of first- and ...

Same, same but different! —matching entomological traces to a human food source by stable isotope analysis
AbstractBlow flies are important tools in forensic entomology, as they feed and develop on human bodies. This fact can be used to estimate the minimum post mortem interval (PMImin), by classifying the age of the immature stages found on corpses. The capacity to also be able to classify the age of adult flies, or even empty puparia, could increase the timeframe for a PMImin. However, the association of older developmental stages, such as adult flies or their empty cases, with a human cadaver may be challenged, as such specimens could stem from another food source. Analyzing the stable carbon ( δ13C) and nitrogen ( δ15N) i...

Publication date: May 2018Source: Saudi Journal of Biological Sciences, Volume 25, Issue 4Author(s): D.P. Thubru, D.M. Firake, G.T. BehereAbstractLethal and sub lethal effects of fresh and old residues of azadirachtin, spinosad, Bacillus thuringiensis var. kurstaki (Bt var. k), and deltamethrin, were evaluated at their recommended field doses against adult and immature stages of Trichogramma brassicae under in vitro conditions. The experiments were carried out at the Entomology section of Division of Crop Protection, ICAR Research Complex for NEH region, Umiam, Meghalaya, in 2012–2013. The effects of different pesticides...

Characterization of α-Glucosidases From Lutzomyia longipalpis Reveals Independent Hydrolysis Systems for Plant or Blood Sugars
In this report, the authors consider that transglycosylation might be an adaptation for the obtention of monosaccharides from sucrose without the increase in osmolarity, as a simple hydrolytic reaction of a 0.7 M sucrose solution (phloem concentration) might result in osmotic shock for the midgut epithelial cells. In this respect, L. longipalpis enzymes might have the same biochemical adaptation. It would be very interesting to observe if this is a common trait of α-glucosidase from insects feeding on nectar or phloem sap, and verify if this is a case of evolutionary divergence or convergence. Two main mechanisms o...

Docosahexaenoic Acid Increases the Potency of Soluble Epoxide Hydrolase Inhibitor in Alleviating Streptozotocin-Induced Alzheimer ’s Disease-Like Complications of Diabetes
Conclusion In the present study, we demonstrated that sEHI alleviates cognitive and memory impairment associated with diabetes-induced Alzheimer-like complication. The positive effect of sEHI TPPU on memory was associated with a reduction in oxidative stress and inflammation in the brain with a parallel decrease in the mRNA level of APP and activity of AChE. The DHA potentiated the effect of TPPU. Edaravone at a higher dose also alleviated memory impairment via decreasing oxidative stress and inflammation. Author Contributions RP, MA, SA, ML, and SG planned the experiments. RP, NB, KG, MA, and SA performed the experimen...

Amino Acid Utilization May Explain Why Bemisia tabaci Q and B Differ in Their Performance on Plants Infected by the Tomato yellow leaf curl virus
Discussion Research has shown that vectored viruses can alter host plant phenotypes so as to change interactions with other organisms, including interactions between plants, viruses, and insect vectors of viruses (Mauck et al., 2012, 2018; Casteel and Falk, 2016; Eigenbrode and Bosque-Perez, 2016; Mauck, 2016). Insect-vectored viruses can alter many host plant factors, including odors, induced defenses, visual and tactile characteristics, sugars, free amino acids, and secondary metabolites (Bosque-Perez and Eigenbrode, 2011; Casteel et al., 2014; Mauck et al., 2014a,b). In our study, TYLCV significantly altered the free a...

Let Plants be Thy Medicine – You Are What You Eat
Credit: Busani Bafana/IPSBy Esther Ngumbi and Ifeanyi NsoforILLINOIS, United States / ABUJA, Oct 16 2019 (IPS) United Nations World Food Day is celebrated around the world on October 16 under the theme: “Our Actions ARE Our Future. Healthy Diets for a Zero Hunger World”. This theme is timely, especially, because across Africa and around the world, there has been a gradual rise in malnutrition and diet-related non communicable diseases, as highlighted in The Lancet study and a United Nations Report published earlier this year. While 45 percent of deaths in children are from nutrition-related causes, mainly malnu...

Dissipation kinetics and dietary risk assessment of spiromesifen on major summer vegetables using good agricultural practices.
Abstract Dissipation kinetics and dietary risk assessment of spiromesifen is worked out on four summer vegetables viz. okra, chilli, capsicum and brinjal during March-April 2015 at the experimental farm of the Department of Entomology, Dr. Yashwant Singh Parmar University of Horticulture and Forestry Nauni, Solan (HP) using good agricultutral practices (GAP). Two foliar applications of spiromesifen @ 144.0 g.a.i./ha each were given at 10 days interval with a Knapsack sprayer with the first application at the fruit initiation stage. Sample were collected up to 15 days after pesticide application and processed using...

Lead toxicity in Lucilia cuprina and electrochemical analysis: a simple and low-cost alternative for forensic investigation
This study describes for the first time the toxicity analysis of Pb on immature L. cuprina through their survival rate and influence of Pb on immature development. In addition, the bioaccumulation of Pb in the larvae samples was determined based on square wave anodic stripping voltammetry (SWASV) measurements. The results revealed a low limit of detection to Pb (6.5 μg L-1) and the analytical performance was satisfactory because it measures Pb levels in larvae exposed to a diet containing 50 μg Pb g-1. Furthermore, the levels of Pb influenced the survival rate and development time of the immature L. cuprina. Larvae expos...

News at a glance: ‘Cherry-picked’ vaccine guidance, AI-written papers, and an apology for prisoner research
ENVIRONMENT Utah’s Great Salt Lake may dry up within 5 years North America’s largest saline lake could be gone by 2028 if water inflows are not restored, researchers warned last week. The Great Salt Lake in Utah has lost nearly three-quarters of its water and 60% of its surface area since 1950, a report from 32 scientists at multiple institutions concludes, and a recent drought has accelerated the losses. To restore the lake, farmers, homeowners, and others will need to reduce the amount of water they take from feeder streams by 30% to 50% . If they don’t, the continent could lose a key habitat ...

Effects of population variations and temperature on Chrysomya megacephala (Diptera: Calliphoridae) development: implications for estimating the postmortem interval
AbstractForensic entomology requires knowledge of the developmental rates of the species that colonize a body after death to estimate the postmortem interval (PMI). These developmental rates may vary depending not only on the species but also on the geographic location due to population differences. Therefore, the objectives of this work were to determine the developmental duration of the forensically important flyChrysomya megacephala under constant controlled and field condition temperatures and to compare these results, through a meta-analysis, with data reported by other authors on populations from different localities...
