Spatial and temporal analyses of Dermacentor variabilis (Say) (Acari: Ixodidae) in central and eastern Canada

open access: yesMedical and Veterinary Entomology, EarlyView.
One thousand one hundred ninety‐eight adult Dermacentor variabilis (Say), a species of veterinary and human medical importance, were collected from companion animals in central and eastern Canada. Peaks in adult D. variabilis submissions occurred in May and June across the provinces. Most submissions of adult D.

Upper Cretaceous Mollusca from Southern California [PDF]

open access: yes, 1937
One new genus and thirteen new species of Mollusca are described from the Upper Cretaceous fauna of the Santa Ana Mountains, southern California. New generic assignments based upon discovery and study of previously unobserved structural features are ...

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

open access: yesMedical and Veterinary Entomology, EarlyView.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

A fijivirus capsid protein hijacks autophagy degrading an ω‐3 fatty acid desaturase to suppress jasmonate‐mediated antiviral defence

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Plant viruses often suppress jasmonic acid (JA)‐mediated defences through disturbing JA signalling or biosynthesis pathways to benefit their own infection. Few studies have examined how the precursors of JA biosynthesis are regulated by viral infection.

BpWRKY6 regulates insect resistance by affecting jasmonic acid and terpenoid synthesis in Betula platyphylla

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Forest pests and diseases pose serious threats to the sustainable development of forestry. Plants have developed effective resistance mechanisms through long‐term evolution. Jasmonic acid and terpenoids play important roles in the defence response of plants against insects.

Vitis vinifera (Vitales: Vitaceae) as a Reproductive Host of Spissistilus festinus (Hemiptera: Membracidae). [PDF]

open access: yes, 2018
Feeding by the three-cornered alfalfa hopper, Spissistilus festinus (Say) (Hemiptera: Membracidae) results in girdling of grapevine petioles and shoots. Its significance as an economic pest of grape has increased since it was shown to transmit Grapevine ...

Comparative metabolomics reveals how the severity of predation by the invasive insect Cydalima perspectalis modulates the metabolism re–orchestration of native Buxus sempervirens

open access: yesPlant Biology, EarlyView.
Combining NMR– and LC–HRMS–based metabolomics reveals that root and leaf metabolic changes in boxwood predated by box–tree moth occur at the same density of predation for both central and specialized metabolisms. Abstract The recent biological invasion of box tree moth Cydalima perspectalis on Buxus trees has a major impact on European boxwood stands ...

Eco‐evolutionary factors contribute to chemodiversity in aboveground and belowground cucurbit herbivore‐induced plant volatiles

open access: yesPlant Biology, EarlyView.
Herbivore‐induced plant volatiles differ between aboveground leaves and belowground roots both within and among plant species in the Cucurbitaceae, and these differences are correlated with plant domestication and herbivore coexistence history, but not phylogenetic relatedness. Abstract When attacked by insect herbivores, plants emit blends of chemical
