Nutritional effects on the expression of cryptic pigmentation in freshwater isopods

open access: yesOikos, EarlyView.
Cryptic pigmentation is a key phenotypic adaptation that helps many benthic invertebrates evade visual predators. However, little is known about whether and how the expression of pigmentation phenotypes that match the habitat background is influenced by the availability of nutritional resources.

Shoot Borer Earias Vittella—A Threat to the Indigenous Vegetable Pele Abelmoschus Manihot in the Pacific

open access: yesProceedings, 2020
The indigenous vegetable Abelmoschus manihot (Malvaceae) is one of the staple crops in the Pacific island countries. It is known by various local names, including Pele (Samoa, Tonga), Bele (Fiji), Aibika (Papua New Guinea), and slippery cabbage (Solomon ...

Lepidoptera of Canada [PDF]

open access: yesZooKeys, 2019
The known Lepidoptera (moths and butterflies) of the provinces and territories of Canada are summarised, and current knowledge is compared to the state of knowledge in 1979. A total of 5405 species are known to occur in Canada in 81 families, and a further 50 species have been reported but are unconfirmed.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

open access: yesOikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Foraging Behavior of the Blue Morpho and Other Tropical Butterflies: The Chemical and Electrophysiological Basis of Olfactory Preferences and the Role of Color

open access: yesPsyche: A Journal of Entomology, 2012
Inside a live butterfly exhibit, we conducted bioassays to determine whether the presence of color would facilitate the location of attractants by the butterflies.

Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

open access: yesOikos, EarlyView.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Resistance mechanisms in collard green genotypes to Plutella xylostella: role of physical and morphological traits

open access: yesPest Management Science, EarlyView.
Resistance to Plutella xylostella in collard greens is mediated by antixenosis and antibiosis, associated with traits such as leaf wax, hardness, and color. Genotypes showed strong resistance potential, supporting their use in breeding and integrated pest management strategies. Abstract BACKGROUND The diamondback moth, Plutella xylostella (Lepidoptera:
