Primary and secondary atmospheric pollutants, including carbon monoxide (CO), dioxide (CO2), nitrogen oxides (NOx), ozone (O3), sulphur (SO2) particulate matter (PM2.5/PM10) with associated heavy metals (HMs) micro- nanoplastics (MPs/NPs), have the potential to influence alter interspecific interactions involving insects that are responsible for providing essential ecosystem services (ESs). Given rely on olfactory cues vital processes such as locating mates, food sources oviposition sites, volatile organic compounds (VOCs) of paramount importance in insects. While gaseous pollutants reduce lifespan individual act cues, can their biosynthesis emission exert a direct effect system Consequently, air affect functioning regulated by plant-insect interactions.

Urban bumblebees diversify their foraging strategy to maintain nutrient intake

Anthropogenic ecosystems can alter individual functions and ecological processes such as resource use species interactions. While variability of morphological traits involved in diet has been observed between urban non-urban populations pollinators, the consequences on dietary pollen-transport patterns remain poorly understood. Here, we investigate breadth rural individuals two bumblebee for nutrient intake pollen transport. We show that bumblebees exhibit a larger than their counterparts, driven by enhanced floral diversity cities. However, found remained similar across ecosystems, indicating bumblebees' foraging strategies be adapted terms to maintain ratios critical nutrients. also distinct individuals, with being more dissimilar ones transported both body leg baskets. Our findings highlight importance considering complementary facets species’ interactions when assessing effects anthropogenic ecosystems.

Impact of Mulches on Floral Visitors in Day‐Neutral Strawberries and Contribution of Syrphid Flies to Strawberry Pollination

Journal of Applied Entomology, Год журнала: 2025, Номер unknown

ABSTRACT Animal‐mediated pollination is essential for the production of many specialty crops, with insects, primarily bees, serving as predominant pollinators in agroecosystems. However, increasing management problems honey bees and declines native bee populations due to various environmental stressors have highlighted importance promoting wild other insect ensure sustainable services. This study explores impact mulches on abundance richness floral visitations by insects role syrphid flies a day‐neutral strawberry system. Four different types were evaluated at University Wisconsin West Madison Agricultural Research Station Wisconsin, USA , during 2022 2023 growing seasons, included three polyethylene colour (black, white black, reflective metallic) one brown soil‐biodegradable paper mulch. Observations pollinator conducted, grouped into broad morphotypes. In addition, sampled assess their pollen loads. Mulch type did not significantly affect overall or visiting flowers. Syrphid most abundant visitors, followed small dark green Orius spp., while Bombus spp. found low numbers. Toxomerus marginatus margined calligrapher, was species collected, representing 72% all collected. Overall, 31% captured carried pollen. A few significant amounts (> 200 grains) body. The findings suggest that mulch visitation, may be important pollination, they abundant, least 2022, carry Our results underscore need further research understand complex non‐bee investigate

Behavioral state influences encoding mechanisms of color and odor integration in a model insect, the bumblebee Bombus impatiens

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Abstract Bumblebees rely on diverse sensory information to locate flowers while foraging. The majority of research exploring the relationship between visual and olfactory floral cues is performed at local spatial scales applicable understanding selection. Floral cue-use during search remains underexplored. This study investigates how bumblebee Bombus impatiens uses versus from across behavioral states scales. At scales, non-flying animals in an associative learning paradigm will access learned multimodal elemental fashion - where a single component cue capable eliciting responses. However, bumblebees flying windtunnel shift strategy depending spatiotemporal scale encounter. When both color odor mimic local/ within patch scale, exhibit gradient responses with highest complete color+odor cue, followed by intact color, then odor. intermediate/ configural high only cue. Thus underlying physiological state, sensitive activity level information, modulating encoding utilization cues.

Floral Cues and Flower Handling Tactics Affect Switching Decisions by Nectar-Foraging Bumble Bees

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Опубликована: Май 2, 2024

Abstract Nectar foraging bees change their use of floral resources as plant species appear in the environment and disappear over lifetimes. The new flowers used may involve different cues nectar extraction tactics. Although bumble can adapt to changes required tactics, little is known about whether prioritize switching tactics or when deciding which switch to. In a laboratory assay, we forced Bombus impatiens (common eastern bee) workers either handling tactic they were using continue but colour artificial foraged on. We examined bees’ tendency was influenced by how similar novel familiar ones. conducted 2 × factorial experiment flowers, manipulating that initially trained (legitimate visitation robbing) similarity between colours (similar distinct). found under most conditions preferred flower retain However, given experience with legitimate markedly from those had experienced previously, tended while continuing forage on same colour. These findings suggest resource currently exploited resource, along employed bees, jointly plays an important role decision-making bees.
