Vertical and temporal niche partitioning in Amazonian butterflies: implications for the evolution of thermal tolerance

Oikos, EarlyView.
Closely related species living in sympatry are often partitioned into divergent ecological niches. Such specialization can be enabled by the evolution of divergent traits enhancing adaptation to different niches. In this study, we investigate the partitioning of closely related butterfly species into different forest strata and daily activity time and ...

Metabolism of Epoxidised Withanolides by a Generalist and a Specialist Insect Species

ChemistryOpen, EarlyView.
Larvae of Heliothis (Chloridea) virescence and subflexa have the ability to convert the epoxidized terpenoid 4β‐hydroxywithanolide E (4BHWE) to withanolide S. The conversion is found by feeding the larvae an artificial diet supplemented with 13C‐labeled 4BHWE.

Injection but not ingestion of a mixed virus suspension in Queensland fruit fly (Bactrocera tryoni) shifts persistent covert infection to acute pathology

Pest Management Science, EarlyView.
Covert and persistent infections with multiple insect‐specific viruses are common in pest fruit flies and may affect pest management strategies. Our study investigated the host effects and viral loads of cripavirus and iflavirus as persistent infections in Queensland fruit fly, and after injection and ingestion of a mixed virus suspension containing ...
