Faunistic patterns of leaf beetles (Coleoptera, Chrysomelidae) within elevational and temporal gradients in Sierra de San Carlos, Mexico

open access: yesZooKeys, 2016
The study of biodiversity of Chrysomelidae in Mexico and its variation within ecological gradients has increased recently, although important areas in the country remain to be explored.

Does a shift to a novel host plant create a defence‐free space for a specialist herbivore species?

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 2085-2095, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While host switches can promote speciation in herbivorous insects, the benefits of switching hosts have only been ascribed to escaping competition and natural enemies. Herbivores might also escape from the defences of their ancestral host if their new host species lacks

Nomenclatural notes on Chalepini and Sceloenopliini (Coleoptera: Chrysomelidae: Cassidinae) [PDF]

open access: yes, 2010
The authorship and type species of the genera Acentroptera and Metazycera are reviewed. The correct author of Acentroptera is Guérin-Méneville, 1844; Acentroptera dejeani Guérin-Méneville, 1844, is here designated as the type species.

No evidence of a common pattern of taxon or phylogenetic diversity across elevation for beetle (Coleoptera) families

open access: yesEcological Entomology, Volume 50, Issue 4, Page 595-608, August 2025.
The two most diverse beetle families, Staphylinidae and Curculionidae (black arrows), have fewer studies of diversity and elevation than expected, while the Carabidae and Scarabaeidae (brown arrows) are overstudied. Dung beetle (Scarabaeidae) phylogenetic and taxonomic diversity decreases with elevation along tropical and temperate elevational ...

The quest for the best target genes for RNAi‐mediated pest control

open access: yesInsect Molecular Biology, Volume 34, Issue 4, Page 505-517, August 2025.
A major challenge for RNAi mediated pest control is the identification of the most effective RNAi target genes from the pool of ~37% of all genes that are essential. Effective RNAi target genes are predominantly highly conserved genes serving basic cellular functions such as protein degradation.

Pepila Weise: Taxonomic identity of the genus and revision of the megalopoides species-group, and description of two new species from Australia (Coleoptera: Chrysomelidae: Alticinae)

open access: yesEuropean Journal of Entomology, 2003
In this paper some taxonomic observations on the Australian flea beetle genus Pepila Weise, 1923 are reported. The following species are transferred to the genus Pepila and lectotypes for them designated: Chaetocnema carinata Baly, 1877; Plectroscelis ...

Environmental factors affecting RNAi efficacy: Temperature but not plant cultivar influences Colorado potato beetle's response to insecticidal dsRNA

open access: yesInsect Molecular Biology, Volume 34, Issue 4, Page 581-592, August 2025.
Colorado potato beetle's RNA interference (RNAi) response was enhanced when insecticidal dsactin was consumed at high temperatures. The enhanced RNAi outcomes at high temperatures were not a function of dose or the expression of core RNAi genes. The potato cultivar consumed by Colorado potato beetle larvae did not affect RNAi outcomes, but larvae did ...

Host plant location by Chrysomelidae

open access: yesBasic and Applied Ecology, 2007
Summary Chrysomelidae are a taxon with an enormous plethora of highly specialised herbivorous species. The present study provides an overview of the knowledge available so far on cues guiding chrysomelids to locate a host plant. Host location behaviour will be addressed from different trophic perspectives.

Revision of the species of Chaetocnema from Madagascar (Coleoptera: Chrysomelidae: Alticinae)

open access: yesEuropean Journal of Entomology, 2001
The species of flea beetles of the genus Chaetocnema Stephens, 1831 occurring in Madagascar are revised. Four new species (C. cachani, C. hygrophila, C. malgascia and C. orophila) are described and five species (C. bamakoensis Bechyné C. confinis Crotch,
