Potential of endophytic Beauveria bassiana against Coraebus (Coleoptera: Buprestidae) oak borers

Pest Management Science, Volume 82, Issue 4, Page 3523-3531, April 2026.
This study demonstrates that an endophytic, oak‐associated strain of Beauveria bassiana exhibits adaptations to Quercus plants and potential against Coraebus boring beetles, supported by distinctive biological traits. Abstract BACKGROUND Oak borers in the genus Coraebus, including the bark‐ and the wood‐boring beetles C. florentinus and C. undatus, are

Stem anatomy and ontogeny of vascular variants in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae)

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
An increase in stem thickness and ontogeny of successive cambia, intraxylary cambium, and inter‐and intraxylary phloem is elaborated for the first time in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae). As the plants grew older, several small segments of cambium were initiated simultaneously external to the phloem formed by regular ...

Synchrony strategies of six gall inducers that share a superhost, Eugenia copacabanensis (Myrtaceae)

Plant Biology, Volume 28, Issue 1, Page 225-239, January 2026.
Galling insects on the superhost Eugenia copacabanensis have developed different life cycle strategies to synchronize with plant seasonal changes and avoid competition for resources. Abstract The life cycles of galling insects are synchronized with their host plant phenology, allowing them to better explore available resources.
