“…The isomeric proportions of solenopsins were determined by a Gas Chromatography system coupled with Mass Spectrometry (GCMS, QP2010A Shimadzu, Rio de Janeiro, Brazil) according to procedures detailed in Fox et al [51] (also see Supplementary Files). Obtained chromatogram peaks were identified as also described in [51] and tentatively quantified by relative area to an external standard (nicotine from Sigma-Aldrich, Mendota Heights, MN, USA) at 0.5 µg/µL using OpenChrom v. 1.1.0 (University of Hamburg, Hamburg, Germany).…”

Biofilm formation on exposed surfaces is a serious issue for the food industry and medical health facilities. There are many proposed strategies to delay, reduce, or even eliminate biofilm formation on surfaces. The present study focuses on the applicability of fire ant venom alkaloids (aka ‘solenopsins’, from Solenopsis invicta) tested on polystyrene and stainless steel surfaces relative to the adhesion and biofilm-formation by the bacterium Pseudomonas fluorescens. Conditioning with solenopsins demonstrates significant reduction of bacterial adhesion. Inhibition rates were 62.7% on polystyrene and 59.0% on stainless steel surfaces. In addition, solenopsins drastically reduced cell populations already growing on conditioned surfaces. Contrary to assumptions by previous authors, solenopsins tested negative for amphipathic properties, thus understanding the mechanisms behind the observed effects still relies on further investigation.

The ontogeny of an organism provides fundamental insights into its life history and evolutionary background. Among insects, especially ants, relatively few observations have been formalized about the morphology of immature stages. Using light and scanning electron microscopy, this study presents the first description of the different larval instars of Aphaenogaster cristata (Forel, 1902) and Aphaenogaster pachei (Forel, 1906), species endemic to the Himalayas that predominate in areas where cold temperature stress and disturbances limit the presence of other ants. The existence of four larval instars was estimated based on the frequency distribution of their measured maximum head widths. We observed discrete alterations in the body constitution and parts among the different instars, suggesting they must follow similar habits until pupation. The two species, however, present noticeable particularities in their mandibles and hair types, suggesting intrinsic life adaptations. Observed traits complementary with previous descriptions with larvae of the genus and related taxa are suggestive of considerable evolutionary distance from Messor, considered the sister clade, which merits further taxonomic investigation in future studies.
