Abstract Sustainable agriculture requires balancing crop yields with the effects of pesticides on non-target organisms, such as bees and other pollinators. Field studies demonstrated that agricultural use neonicotinoid insecticides can negatively affect wild bee species 1,2 , leading to restrictions these compounds 3 . However, besides neonicotinoids, field-based evidence landscape pesticide exposure is lacking. Bees encounter many in landscapes 4–9 this colony growth development any remains unknown. Here we show found bumble bee-collected pollen are associated reduced performance during bloom, especially simplified intensive practices. Our results from 316 Bombus terrestris colonies at 106 sites across eight European countries confirm regulatory system fails sufficiently prevent pesticide-related impacts even for a eusocial pollinator which size may buffer against 10,11 These findings support need postapproval monitoring both process protective limiting collateral environmental damage use.

Ecological traits interact with landscape context to determine bees’ pesticide risk

Widespread contamination of ecosystems with pesticides threatens non-target organisms. However, the extent to which life-history traits affect pesticide exposure and resulting risk in different landscape contexts remains poorly understood. We address this for bees across an agricultural land-use gradient based on assays pollen nectar collected by Apis mellifera, Bombus terrestris Osmia bicornis, representing extensive, intermediate limited foraging traits. found that extensive foragers (A. mellifera) experienced highest risk-additive toxicity-weighted concentrations. only (B. terrestris) (O. bicornis) responded context-experiencing lower less land. Pesticide correlated among bee species between food sources was greatest A. mellifera-collected pollen-useful information future postapproval monitoring. provide trait- landscape-dependent occurrence, concentration identity encounter estimate risk, is necessary more realistic assessment essential tracking policy goals reduce risk.

Pesticide Exposure and Effects on Non-Apis Bees

Annual Review of Entomology, Год журнала: 2023, Номер 69(1), С. 551 - 576

Bees are essential pollinators of many crops and wild plants, pesticide exposure is one the key environmental stressors affecting their health in anthropogenically modified landscapes. Until recently, almost all information on routes impacts came from honey bees, at least partially because they were only model species required for risk assessments (ERAs) insect pollinators. Recently, there has been a surge research activity focusing effects non- Apis including other social bees (bumble stingless bees) solitary bees. These taxa vary substantially another several important ecological traits, spatial temporal patterns, foraging nesting requirements, degree sociality. In this article, we review current evidence base about pathways consequences We find that insights into bee resulting across biological organizations, landscapes, mixtures, multiple still infancy. The good news promising approaches could be used to advance our understanding, with priority given informing pathways, extrapolating effects, determining how well (limited very few mostly neonicotinoid insecticides under unrealistic conditions) can generalized diversity lifestyles global community. conclude future expand knowledge would also beneficial ERAs wider policy decisions concerning pollinator conservation regulation.

Abstract Current use pesticides (CUPs) are recognised as the largest deliberate input of bioactive substances into terrestrial ecosystems and one main factors responsible for current decline in insects agricultural areas. To quantify seasonal insect exposure landscape at a regional scale (Rhineland-Palatine Germany), we analysed presence multiple (93) active ingredients CUPs across three different cultivation types (with each fields: arable, vegetable, viticulture) neighbouring meadows. We collected monthly soil vegetation samples over year. A total 71 CUP residues mixtures was detected, with up to 28 25 single samples. The concentrations numbers fluctuated sampling period, peaking summer months but remaining almost constant topsoil. calculated in-field additive risks earthworms, collembola, soil-living wild bees using measured CUPs. Our results call need assess mixture low concentrations, chronically present Since this risk is not addressed regulation, emphasise urgent implement global pesticide reduction targets.

The Resilience of Plant–Pollinator Networks

Annual Review of Entomology, Год журнала: 2022, Номер 68(1), С. 363 - 380

There is growing awareness of pollinator declines worldwide. Conservation efforts have mainly focused on finding the direct causes, while paying less attention to building a systemic understanding fragility these communities pollinators. To fill this gap, we need operational measures network resilience that integrate two different approaches in theoretical ecology. First, should consider range conditions compatible with stable coexistence all species community. Second, address rate and shape collapse once safe space exited. In review, describe integrative approach several mechanisms may enhance communities, chiefly rewiring interactions, increasing heterogeneity, allowing variance, enhancing coevolution. The most pressing develop ways reduce gap between recommendations practical applications. This perspective shifts emphasis from traditional focusing equilibrium states strategies allow pollination networks cope global environmental change.

Single and combined exposure to ‘bee safe’ pesticides alter behaviour and offspring production in a ground-nesting solitary bee ( Xenoglossa pruinosa )

Mounting evidence supporting the negative impacts of exposure to neonicotinoids on bees has prompted registration novel ‘bee-friendly’ insecticides for agricultural use. Flupyradifurone (FPF) is a butenolide insecticide that shares same mode action as and been assessed be ‘practically non-toxic adult honeybees' using current risk assessment procedures. However, these assessments overlook some routes specific wild bees, such contact with residues in soil ground-nesters. Co-exposure other pesticides may also lead detrimental synergistic effects. In fully crossed experiment, we possible lethal sublethal effects chronic two used Cucurbita crops, Sivanto Prime fungicide Quadris Top (azoxystrobin difenoconazole), alone or combined, solitary ground-nesting squash ( Xenoglossa pruinosa ). Squash exposed collected less pollen per flower visit, while Sivanto-exposed produced larger offspring. Pesticide co-exposure induced hyperactivity female relative both control single pesticide exposure, reduced number emerging offspring nest compared individual treatments. This study demonstrates ‘low-toxicity’ can adversely affect under field-realistic combination.
