The Plant‐Associated Fungus Chaetomium globosum Can Directly Infect and Kill Aphids
Entomologia Experimentalis et Applicata, EarlyView.Plant‐associated Chaetomium globosum strains caused direct infection and mortality in cotton aphids (Aphis gossypii) under different concentration‐dependent pathogenicity bioassays. Reinfection, aphid mortality, fungal re‐isolation, and molecular identification confirmed fulfillment of Koch's postulates for insect pathogenicity. These findings revealed

Ecological Entomology, EarlyView.We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.

Ecological Entomology, EarlyView.Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Ecological Entomology, EarlyView.Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.

Journal of Fish Diseases, EarlyView.ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...

Journal of Zoology, EarlyView.Gammarus pulex infected by Pomphorhynchus laevis at the cystacanth larval stage. We investigated whether geographic origin influences infection success of the acanthocephalan Pomphorhynchus laevis across its complex life cycle. Parasites from different watersheds showed strong differences in infection success and virulence in intermediate hosts ...

Diet and leishmaniasis in the Ecuadorian Amazon
Medical Anthropology Quarterly, EarlyView.Abstract In Ecuador's Amazon, Indigenous communities affected by leishmaniasis often modify their diets as part of their health‐seeking practices. Drawing on qualitative research with sixty‐eight participants from seven Indigenous groups, this study explores how and why patients’ diets shift in pursuit of healing from leishmaniasis.
