The aim of this study was to evaluate the influence of the bioactive nonpolar fraction of geopropolis on Streptococcus mutans biofilm. The ethanolic extract of Melipona scutellaris geopropolis was subjected to a liquid-liquid partition, thus obtaining the bioactive hexane fraction (HF) possessing antimicrobial activity. The effects of HF on S. mutans UA159 biofilms generated on saliva-coated hy...

Megamelus scutellaris Berg (Hemiptera: Delphacidae) is the most recent of nine biological control agents developed to manage invasive water hyacinth, Pontederia (=Eichhornia) crassipes Mart. (Pontederiaceae), in South Africa. More than a million M. have been mass-reared and released since first introduction agent into Africa 2013, successfully establishing overwintering populations at 32 sites ...

A farmer's survey was carried from March to December, 2021 randomly selecting 40 orchard owners, and at the same time, a field monitoring fruit organised randomized complete block design with 7 times replicated 3 treatments (Cue lure malathion Steiner trap, Methyl eugenol trap protei...

Abstract The West-Palaearctic Colobopsis ant populations have long been considered a single species (Colobopsis truncata). We studied the diversity of this by employing multidisciplinary approach and combining data from our surveys, museum private collections, citizen science platforms. As result, we revealed existence second species, which describe as imitans sp. nov., distributed allopatrical...
