Summer Rainfall Drives Adaptation with Gene Flow in a Widespread Butterfly
ABSTRACT Understanding how environmental variation interacts with gene flow to shape population genomic patterns is a central goal in evolutionary biology. We investigated how geographic and environmental differences impact genetic variation in the clouded sulfur butterfly (Colias philodice eriphyle) by conducting whole‐genome resequencing across ...

Arboviral diseases spread by Culicoides biting midges have been introduced into Europe by unknown means. A possible route is the carriage of midges with cut flowers shipped to flower markets. We sampled Culicoides in and around a cut flower farm in Kenya; midges were caught in the vicinity and a greenhouse, but not where flowers are processed.

Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

(A) The predator Phytoseiulus persimilis and its prey Tetranychus urticae were reared under mild or extreme heat waves from egg to adulthood, which resulted in asymmetrical thermal shifts of adult body sizes in favour of prey under extreme heat waves. (B) Single couples of adult predators and prey, reared under mild heat waves interacted at mild heat ...
