A worldwide survey of neonicotinoids in honey

Science, Год журнала: 2017, Номер 358(6359), С. 109 - 111

Опубликована: Окт. 5, 2017

Growing evidence for global pollinator decline is causing concern biodiversity conservation and ecosystem services maintenance. Neonicotinoid pesticides have been identified or suspected as a key factor responsible this decline. We assessed the exposure of pollinators to neonicotinoids by analyzing 198 honey samples from across world. found at least one five tested compounds (acetamiprid, clothianidin, imidacloprid, thiacloprid, thiamethoxam) in 75% all samples, 45% contained two more these compounds, 10% four five. Our results confirm bees their food throughout The coexistence other may increase harm pollinators. However, concentrations detected are below maximum residue level authorized human consumption (average ± standard error positive samples: 1.8 0.56 nanograms per gram).

Abstract New information on the lethal and sublethal effects of neonicotinoids fipronil organisms is presented in this review, complementing previous Worldwide Integrated Assessment (WIA) 2015. The high toxicity these systemic insecticides to invertebrates has been confirmed expanded include more species compounds. Most recent research focused bees ecological impacts have pollinators.

Neonicotinoid exposure disrupts bumblebee nest behavior, social networks, and thermoregulation

Science, Год журнала: 2018, Номер 362(6415), С. 683 - 686

Опубликована: Ноя. 8, 2018

Trouble at the hive Neonicotinoid pesticides cause mortality and decline in insect pollinators. One repeatedly noted effect is a reduction bee colony size. However, mechanism behind this unclear. Crall et al. performed complex real-time monitoring of bumblebee behavior within their nests (see Perspective by Raine). exposure reduced nurse caretaking behaviors, which affected productivity harmed thermoregulation. These changes acted together to decrease viability, even when was nonlethal. Science , issue p. 683 ; see also 643

Trends in neonicotinoid pesticide residues in food and water in the United States, 1999–2015

Neonicotinoids are a class of systemic insecticides widely used on food crops globally. These pesticides may be found in “off-target” items and persist the environment. Despite potential for extensive human exposure, there limited studies regarding prevalence neonicotinoid residues foods sold consumed United States. Residue data seven collected between 1999 2015 by US Department Agriculture’s Pesticide Data Program (PDP) were collated summarized year across various commodities, including fruit, vegetable, meat, dairy, grain, honey, baby food, as well water to qualitatively describe examine trends contamination frequency residue concentrations. The highest detection frequencies (DFs) neonicotinoids all commodities generally below 20%. Average DFs over entire study period, 1999–2015, domestic imported similar at 4.5%. For samples (both imported) imidacloprid was with overall 12.0%. However, higher observed specific commodity-neonicotinoid combinations such as: cherries (45.9%), apples (29.5%), pears (24.1%) strawberries (21.3%) acetamiprid; cauliflower (57.5%), celery (20.9%), (26.3%), cilantro (30.6%), grapes (28.9%), collard greens (24.9%), kale (31.4%), lettuce (45.6%), potatoes (31.2%) spinach (38.7%) imidacloprid. also detected organic (DF < 6%). Individual least 5% testing positive two or more included apples, celery, cherries. Generally, did not exceed Environmental Protection Agency tolerance levels.

The relationship between pesticides and pollinators, while attracting no shortage of attention from scientists, regulators, the public, has proven resistant to scientific synthesis fractious in matters policy public opinion. This is part because issue been approached a compartmentalized intradisciplinary way, such that evaluations organismal pesticide effects remain largely disjoint their upstream drivers downstream consequences. Here, we present socioecological framework designed synthesize pesticide-pollinator system inform future scholarship action. Our consists three interlocking domains-pesticide use, exposure, effects–each consisting causally linked patterns, processes, states. We elaborate each these domains linkages, reviewing relevant literature providing empirical case studies. then propose guidelines for action agenda aimed at strengthening knowledge neglected integrating across provide decision support stakeholders policymakers. Specifically, emphasize (1) stakeholder engagement, (2) mechanistic study (3) understanding propagation levels organization, (4) full-cost accounting externalities use regulation. Addressing items will require transdisciplinary collaborations within beyond community, including expertise farmers, agrochemical developers, policymakers an extended peer community.

Monitoring the environment for pollution, pesticides, and pathogens is crucial protecting human, agriculture, overall ecosystem health. Diverse strategies ranging from physical sensors to sentinel species have been used environmental monitoring. The European honey bee, Apis mellifera, a globally managed pollinator that can serve as continuous biomonitoring species. During foraging, bees are exposed contaminants carry them their hives where they be detected quantified. Although individual vulnerable stressors, bee colony whole more resilient accumulate or respond without collapsing. This allows long-term monitoring of map in geographical area study ecotoxicology gradients over space time. In this paper, we review demonstrated proposed uses We focus our discussion on heavy metals, air pollutants, plant hive materials including honey, wax, stored pollen. present use gene expression, microbiome profiling, other high-throughput methodologies dose-dependent exposure increase detection sensitivity; example, pollen analysis with next generation sequencing reveal presence viruses, fungi, invasive earlier than traditional methods.
