The potential of the solitary parasitoid Microctonus brassicae for the biological control of the adult cabbage stem flea beetle, Psylliodes chrysocephala

The cabbage stem flea beetle (CSFB), Psylliodes chrysocephala L. (Coleoptera: Chrysomelidae), is a major pest of oilseed rape, Brassica napus L. (Brassicaceae), within the UK and continental Europe. Following the withdrawal of many broad‐spectrum pesticides, most importantly neonicotinoids, and with increased incidence of pyrethroid resistance, few chemical control options remain, resulting in the need for alternative pest management strategies. We identified the parasitoid wasp Microctonus brassicae (Haeselbarth) (Hymenoptera: Braconidae) within CSFB collected from three independent sites in Norfolk, UK. Parasitism of adult CSFB was confirmed, and wasp oviposition behaviour was described. Moreover, we show that within captive colonies parasitism rates are sufficient to generate significant biological control of CSFB populations. A sequence of the M. brassicae mitochondrial cytochrome oxidase 1 (MT‐CO1) gene was generated for rapid future identification. Moroccan specimens of Microctonus aethiopoides (Loan), possessing 90% sequence similarity, were the closest identified sequenced species. This study represents the first description published in English of this parasitoid of the adult cabbage stem flea beetle.© 2020 The Authors.

Revision of the genus Syntretus Foerster (Hymenoptera: Braconidae: Euphorinae) from Europe

The species of the genus Syntretus Foerster, 1862 (including Falcosyntretus Tobias, 1965, and Exosyntretrus Belokobylskij, 1998) (Braconidae: Euphorinae; Syntretini) from Europe are revised and keyed. The genera Falcosyntretus Tobias, 1965, Exosyntretus Belokobylskij, 1998, and Parasyntretus Belokobylskij, 1993, are synonymised with Syntretus Foerster, 1862, and the second one is provisionally used as a subgenus (stat. rev.). The subgenus Exosyntretrus is reported for the first time from Europe and two new species are included. In total twenty species of the genus Syntretus Foerster are recognised (plus one species only known from literature: Syntretus dzieduszykii Niezabitowski, 1910), of which ten are new: Syntretus breviradialis spec. nov., S. flevo spec. nov., S. fuscicoxis spec. nov., S. fuscivalvis spec. nov., S. minimus spec. nov., S. ocularis spec. nov., S. shawi spec. nov., S. stenochora spec. nov., S. taegeri spec. nov., and S

Comparative proteome analysis of culture supernatant proteins from virulent Mycobacterium tuberculosis H37Rv and attenuated M-bovis BCG Copenhagen

A comprehensive analysis of culture supernatant (CSN) proteins of Mycobacterium tuberculosis H37Rv was accomplished by combination of two-dimensional electrophoresis (2-DE), mass spectrometry, and N-terminal sequencing by Edman degradation. Analytical 2-DE gels resolved approximately 1250 protein spots from CSN of M. tuberculosis H37Rv, 381 of which were identified by mass spectrometry and/or Edman degradation. This study revealed 137 different proteins, 42 of which had previously been described as secreted. Comparative proteome analysis of CSN from virulent M. tuberculosis H37Rv and attenuated Mycobacterium bovis BCG Copenhagen identified 39 M. tuberculosis-specific spots containing 27 different proteins, representing candidate antigens for novel vaccines and diagnostics in tuberculosis. These included five proteins encoded by open reading frames absent from M. bovis BCG, e.g., early secretory antigen target (Esat6), as well as 22 novel differential proteins, such as acetyl-CoA C-acetyltransferase (Rv0243) and two putative Esat6-like proteins (Rv1198, Rv1793)
