  In vitro evaluation of venom extracts of Sphecid wasps against phytopathogens of horticultural crops and mass spectrometric profiling of venom peptide components Abstract As the shortcomings of synthetic chemicals become gradually evident, the dynamics of pest and disease management in modern agriculture are progressively shifting towards environmentally safer alternatives. Biopesticides, such as peptide-based approaches offer attractive alternatives, although their potential remains yet to be fully explored. In this exploratory study, crude venom extracts from previously unexplored Hymenopteran sphecid wasps ( Chalybion bengalense , Sceliphron madraspatanum , Ammophila atriceps and Sphex argentatus ) were evaluated for their antimicrobial activity against selected plant pathogens. The venom extracts demonstrated prominent antibacterial activity lacking antifungal activity. Among the wasps, C . bengalense exhibited the most significant antibacterial activity against Gram-negati...

A new species of Otacilia Thorell, 1897 (Araneae, Phrurolithidae) from Tongboshan National Nature Reserve, Jiangxi Province, China

Abstract

Background

Sixty-four phrurolithid species were found from Jiangxi Province in the past five years. However, there are still many unknown phrurolithid species from this Province with unusual morphological characteristics.

New information

A new species, Otacilia tongboshan Liu, sp. nov. is described from Tongboshan National Nature Reserve, Jiangxi Province, China. Morphological illustrations, SEMs and living photos and a distribution map are given.
