Volatile fatty acids (VFAs) are a group of common metabolites and semiochemicals mediating information transfer between higher organisms and bacteria, either from microbiome or external environment. VFAs commonly occur among various insect orders. There are numerous studies exploring their influence on the behavior of different insect species. In relation to the papers published by J. E. McFarl...

Canthariasis is a human/ animal infestation by larval stages of coleopteran insects - the beetles. This study reports rare case gastrointestinal canthariasis caused Alphitobiusdiaperinus. A six-year-old boy presented with complaints pain abdomen associated non-bilious, non-blood-stained vomiting for 15 days and history passage worm-like creatures via stools occasionally in vomitus. All investig...

The lesser mealworm, Alphitobius diaperinus (Panzer), is an important pest in poultry facilities. The toxicity of cyfluthrin and tetrachlorvinphos to five strains of the lesser mealworm was compared with the toxicity to a susceptible laboratory strain. Bioassays were carried out with both larvae and adults. For the susceptible strain, cyfluthrin and tetrachlorvinphos had similar toxicity to adu...

Mechanical barriers consisting of bands of polyethylene terepthalate resin attached to wooden posts by latex caulk adhesive and staples were 100% effective in preventing passage of dispersing lesser mealworm, Alphitobius diaperinus (Panzer), larvae in the laboratory. Barriers continued to be 100%effective after being held in a caged layer poultry house for 3mo. Polyethylene terepthalate barrier...

In this study, we evaluated the susceptibility of Alphitobius diaperinus larvae and adults to saline extract (SE), lectin-rich fraction (FR), isolated lectin (MvRL) from Microgramma vacciniifolia rhizomes. To determine immediate effects, were exposed SE (10.5 mg/mL), FR (7.5 or MvRL (1.0 mg/mL) for 48 h. Live insects acetylcholinesterase (AChE) activity. The delayed effects (0.2 0.4 checked by ...

AIMS The lesser mealworm, Alphitobius diaperinus is an important poultry pest prevalent during production that is capable of vectoring pathogens. This study was undertaken to determine the gut transit time of Salmonella for biosecurity risk analysis of pathogen dispersal into the environment. METHODS Adult and larval A. diaperinus were exposed to two concentrations of a fluorescently labeled ...
