Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective

Abstract The diverse infraorder Mygalomorphae includes fossorial and cryptic spiders, such as tarantulas and trapdoor spiders. Their ability to disperse is often highly limited, rendering some mygalomorphs as rare short‐range endemics. These species are vulnerable to landscape changes, often hard to detect, and have poorly understood reproductive ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

‘Candidatus Streptomyces philanthi’, an endosymbiotic streptomycete in the antennae of Philanthus digger wasps [PDF]
Symbiotic interactions with bacteria are essential for the survival and reproduction of many insects. The European beewolf (Philanthus triangulum, Hymenoptera, Crabronidae) engages in a highly specific association with bacteria of the genus Streptomyces that appears to protect beewolf offspring against infection by pathogens.
