Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Ants contribute to raspberry pollination in protected cropping systems

open access: yesAgricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

open access: yesAgricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Planting recommendations for blueberry — sweetfern sites in northern Ontario

open access: yesThe Forestry Chronicle, 1975
This is an extension of a 1968 report on experiments established to study species, age-classes, and planting site treatments for blueberry-sweet-fern (Vaccinium-Comptonia) sites in northern Ontario. Red pine (3–0 and 2–2) and jack pine (2–0 and 2–1) were planted in scalped spots, in furrows, in herbicide-spray strips, in ground cover, and in bulldozed

The Outsiders: Principled Withdrawal, Whiteness, and Power in the Los Angeles Food Justice Movement

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT This article draws on understandings of whiteness and the misconstrual of South Central Los Angeles to analyze the power dynamics between “outsider” activists and residents of South Central as they worked toward a more equitable food system.

Feared self and responsibility in obsessive compulsive phenomena

open access: yesBritish Journal of Clinical Psychology, EarlyView.
Abstract Objectives This study investigated the roles of feared self and inflated responsibility in obsessive–compulsive tendencies through an online experiment. Design A total of 185 participants (Mage = 28.11, SD = 9.12) were randomly assigned to either a heightened responsibility or control condition, then primed with feared self scenarios (morality

Powdered hibiscus anthocyanin‐nanofibril complexes as natural colourants: Stability and application in yoghurt and soft candy

open access: yesColoration Technology, EarlyView.
Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

A High‐Resolution Method Using Individual Females to Assess the Competitiveness of Sterile Drosophila suzukii Males Under Semi‐Controlled Conditions

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
A high‐resolution, novel method to assess the sexual competitiveness of sterile mass‐reared Drosophila suzukii males is calibrated and illustrated using different laboratory and wild type strains. Isolation of individual females after semi‐controlled cage competition tests and subsequent observation of their progeny showed that sterile males from two ...

Field Attraction of Natural Enemies to Methyl Salicylate Differs Between Annual and Perennial Cropping Systems

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...
