Coconut rhinoceros beetle Oryctes rhinoceros (Coleoptera: Scarabaeidae) confirmed in the Americas

EPPO Bulletin, Volume 55, Issue 3, Page 511-517, December 2025.
Abstract In 2022, a suspected incursion of Oryctes rhinoceros (coconut rhinoceros beetle, CRB) was reported in Bahía de Banderas, Nayarit, México, based on damage symptoms observed on coconut palms and photographs of beetles on a social media site. This prompted collaboration with local biologists and land managers, and a survey of the area with the ...

Exploration du microbiote pour identifier des antagonistes du mildiou de la vigne

IVES Technical Reviews
Nous avons étudié les communautés microbiennes de parcelles viticoles intégrées à un réseau de surveillance des maladies de la vigne. Nous montrons que plusieurs espèces de champignons et de bactéries sont plus abondantes dans les feuilles et le sol des

Diet breadth modulates preference - performance relationships in a phytophagous insect community

Scientific Reports, 2017
In most phytophagous insects, larvae are less mobile than adults and their fitness depends on the plant chosen by their mother. To maximize fitness, adult preference and larval performance should thus be correlated.

Assessing the Acute and Chronic Effects of Palladium on Daphnia magna and the Influence of Natural Organic Matter

Journal of Applied Toxicology, Volume 45, Issue 11, Page 2363-2377, November 2025.
ABSTRACT In recent decades, rising industrial demand for palladium (Pd), driven by its unique properties and affordability compared to other noble metals, has increased its environmental release into aquatic systems. This highlights the need to assess its effects on organisms, given the lack of standardized toxicity studies and regulations for this ...

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

Journal of Fish Biology, Volume 107, Issue 2, Page 406-418, August 2025.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound

Local environment and sampling bias drive parasite prevalence estimates in freshwater fish communities

Oikos, Volume 2025, Issue 7, July 2025.
Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,
