Global interest on plant-microbe-insect interactions is rapidly growing, revealing the multiple ways in which microorganisms mediate plant-herbivore interactions. Phytopathogens regularly alter whole repertoires of plant phenotypic traits, and bring about shifts in key chemical or morphological characteristics of plant hosts. Pathogens can also cause cascading effects on higher trophic levels, ...

Comments by de Jong et al., Solter et al., and Sloggett question the ecological relevance of the abundant microsporidia found in the invasive ladybird Harmonia axyridis. We contend that there is abundant evidence that native ladybirds feed on H. axyridis eggs and that interspecific microsporidial transfer is a common phenomenon, supporting the proposed role of these parasites as biological weap...

The ladybird beetle genus Hong Ślipiński was previously known from a single female specimen from a subtropical forest in South East Queensland, Australia.

A new genus of ladybird beetles, Ruthmuelleria, belonging to the pantropical tribe Carinodulini, is described based on a new species R. grootdrifensis from South Africa. The genus is diagnosed by the unique 8-segmented antennae and posteriorly-directed metaventral postcoxal lines. A key to the genera and discussion of diagnostic characters of Carinodulini are also included.
