Necrophagous blow flies are a commonly used forensic tool to estimate the minimum postmortem interval (PMI), where researchers collect development data under constant temperature regimes and construct models to estimate PMI. However, the ambient temperatures of real death scenes are often fluctuant, which limits the reliability of data obtained under constant temperature regimes. Here we investigate the possible differences in the development of Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae), an important species in forensic entomology.

Insecticides may facilitate the escape of weeds from biological control.

PeerJ

January 2025

Department of Entomology, The Pennsylvania State University, University Park, PA, United States of America.

Background: Preventative pesticide seed treatments (hereafter preventative pest management or PPM) are common corn and soybean treatments, and often include both fungicides and neonicotinoid insecticides. While PPM is intended to protect crops from soil-borne pathogens and early season insect pests, these seed treatments may have detrimental effects on biological control of weed seeds by insects.

Methods: Here, in two 3-year corn-soy rotations in Pennsylvania USA, we investigated a PPM approach to insect management compared to an integrated pest management approach (IPM) and a "no (insect) pest management" (NPM) control.

The evolving threat of new pathogen variants in the face of global environmental changes poses a risk to a sustainable crop production. Predicting and responding to how climate change affects plant-pathosystems is challenging, as environment affects host-pathogen interactions from molecular to the community level, and with eco-evolutionary feedbacks at play. To address this knowledge gap, we studied short-term within-host eco-evolutionary changes in the pathogen, , on resistant and susceptible pepper in the open-top chambers (OTCs) under elevated Ozone (O) conditions in a single growing season.

Selection on body size tends to favor larger males that outcompete smaller males to mate with females, and larger, more fecund females. For many web-building spiders in the Nephilidae family, reproductive success increases with body size, which in turn, is related to diet. The diet of female spiders may overlap with males who share her web, but diet patterns could depend on size if certain males have better access to prey ensnared in the web.
