New developmental data of Chrysomya megacephala (Diptera: Calliphoridae) in tropical temperatures and its implications in forensic entomology
Trop Biomed. 2023 Mar 1;40(1):1-6. doi: 10.47665/tb.40.1.003.ABSTRACTThe estimation of the postmortem interval (PMI) is an essential information in death investigations. It is necessary to know the developmental data of the most important necrophagous insect species in every geographical area. Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) is one of the most common species associated with human body decomposition, especially in the tropics, so a precise knowledge of its life cycle is crucial. However, despite its ubiquity, developmental data in a range of tropical temperatures is scarce. For this reason, ...

This Year Might Be the Worst Tick Season Ever. Here ’ s Why
Marci Silbert wasn’t walking far on the evening of May 6. She, her husband, and another couple were visiting friends for dinner, and after eating, took a brief stroll down a short path to a small pond on their hosts’ property in the Berkshires in Massachusetts. They lingered for just a few moments, and then walked back. But that was all it took.
The next day, her husband noticed a tick embedded in his forearm. Silbert had one on the inside of her knee, and the husband in the other couple had one on his thigh. Out of an abundance of caution, they went to the hospital, had them removed, and were given prophylacti...

The Least Toxic Ways to Protect Yourself from Ticks
When it comes to keeping away creatures that creep and crawl, the U.S. doesn’t mess around. More than 198 million Americans used insect repellent last year, a figure that is expected to top 200 million this year. Much of that is to ward off ticks, which are technically arachnids and carry more than a dozen diseases.
But the repellents themselves can present concerns of their own with their pungent smells, occasional irritation, and labels full of mystifying chemicals most people have never heard of.

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...

A beetle for prosecution: exogenous DNA detection from larval and adult gut of a Neotropical carrion beetle
This study evaluated whether the Neotropical carrion beetleOxelytrum discicolle (Silphidae) has the potential for the detection of exogenous DNA into the gut. The whole gut or the gut contents were extracted fromO. discicolle larvae and adult previously fed on pig carcass. The pig DNA recovery rate was 33.3% in larvae and 25% in adults, indicating that the carrion beetle ’s gut may be useful for DNA identification of ingested food. Samples with the whole gut or only gut contents showed the same DNA recovery rate. Exogenous DNA from the whole gut was recovered from samples stored in ethanol at -20 ºC for 11 days, showing...

CIGAF —a database and interactive platform for insect-associated trichomycete fungi
We present CIGAF (short for Collections of Insect Gut –Associated Fungi), a trichomycetes-focused digital database with interactive visualization functions enabled by the R Shiny web application. CIGAF curated 3120 collection records of trichomycetes across the globe, spanning from 1929 to 2022. CIGAF allows the exploration of nearly 100 years of f ield collection data through the web interface, including primary published data such as insect host information, collection site coordinates, descriptions and date of collection. When possible, specimen records are supplemented with climatic measures at collection sites. As...

Species diversity pattern of mosquitoes (Diptera: Culicidae) breeding in different permanent, temporary and natural container habitats of Peshawar, KP Pakistan
This study showed that Peshawar valley harbours 15 species from the genera Aedes, Anopheles, Armigeres, Culex and Culiseta. When the density of each species was examined, Culex quinquifasciatus was found to be dominant (79%) and constant in distribution. Among the temporary habitats Aedes albopictus was found as the most prevalent species particularly from tree holes and water cisterns. The highest intensity of mosquitoes was in June (2243 emerged adults) and November (2667 emerged adults) while the lowest was in January (203 emerged adults). A perfect positive correlation (r = +0.8) was found between temperature and popul...
