“…Agrochemicals, including pesticides, herbicides, and fungicides are used widely across a range of landscapes (e.g., agricultural, non-agricultural, wild, managed, and residential), as well as within managed honey bee colonies. Agrochemical exposure sometimes results in acute bee losses, as well as sublethal toxicity, therefore there is much concern regarding the role of pesticides, particularly neonicotinoids, in bee declines (reviewed in [62–64]). Although, the latest insecticide formulations may pose less of a threat to bee health as compared to previous formulations [62,64,65].…”

Although, the latest insecticide formulations may pose less of a threat to bee health as compared to previous formulations [62,64,65]. Compared to other insects, honey bees have a reduced repertoire of genes involved in detoxification [66], and at least one study indicated that bees prefer neonicotinoid-containing food [67]; these studies underscore the importance of further examining the risks associated with agrochemical exposure.…”

Bees are important pollinators of plants in both agricultural and non-agricultural landscapes. Recent losses of both managed and wild bee species have negative impacts on crop production and ecosystem diversity. Therefore, in order to mitigate bee losses, it is important to identify the factors most responsible. Multiple factors including pathogens, agrochemical exposure, lack of quality forage, and reduced habitat affect bee health. Pathogen prevalence is one factor that has been associated with colony losses. Numerous pathogens infect bees including fungi, protists, bacteria, and viruses, the majority of which are RNA viruses including several that infect multiple bee species. RNA viruses readily infect bees, yet there is limited understanding of their impacts on bee health, particularly in the context of other stressors. Herein we review the influence environmental factors have on the replication and pathogenicity of bee viruses and identify research areas that require further investigation.

“…However, the observation that an active ingredient or pesticide product is not having any measurable direct effect (lethal or sub-lethal) at 'field-realistic' levels does not exclude the potential for significant indirect effects that come into play only in the presence of other factors in particular spatio-temporal settings. This scenario of cumulative and interactive multifactoriality is highly plausible [28], given that managed honey bee colonies encounter on a regular basis hundreds of pesticides, transgenic toxins, 'inert' ingredients and other synthetic chemicals, apart from ambient parasites, pathogens, nutritional and other abiotic and biotic variables in the particular landscapes in which they are situated and their multiple routes of exposure [11,29]. Furthermore, the complex structure of a honey bee colony may buffer it from the negative effects of neonicotinoids and other pesticides, to a greater extent than other pollinator species [30].…”

Pesticides and pollinators: a context-sensitive policy approach

I examine recent policymaking efforts in the United States (US) that seek to improve how risks posed by pesticides to insect pollinators are assessed and managed. Utilizing the case of ongoing honey bee die-offs, I argue for a context-sensitive policy framework. From a scientific perspective, this entails not ignoring the uncertain knowledge emerging from laboratory and field studies regarding the indirect effects of low levels of certain insecticides in combination with other factors. From a social scientific perspective, policy initiatives to build partnerships between growers and beekeepers toward mitigating exposure to pesticides are crucial, and need to acknowledge barriers to the adoption of best management practices as well as a historically-established asymmetry between growers and beekeepers in the pollination industry.

“…These chemicals have a substantially lower acute toxicity to humans, birds and mammals than the older insecticides which they replaced. However, evidence is mounting that these chemicals play a key role in bee disorders and pollinator decline observed over the past decades (EASAC 2015; Krupke and Long 2015;Rundlöf et al 2015;SanchezBayo 2014;Van der Sluijs et al 2013aWilliams et al 2015).…”

Pollinators and Global Food Security: the Need for Holistic Global Stewardship

2016

View full text Add to dashboard Cite

Over the past decades, both wild and domesticated insect pollinators are in dramatic decline, which puts at stake the existence of species, ecosystem resilience and global food security. Globally, 87 of major food crops depend on animal pollination. Together these account for 35 % of the world food production volume. Pollinator mediated crops are indispensable for essential micronutrients in the human diet. Many ornamental plants as well as crops for fibre, fodder, biofuels, timber and phytopharmaceuticals also depend on insect pollinators. This article aims to map the current situation of pollinators worldwide, with a focus on the critical role of pollinators in the human food chain and ecosystem sustainability, their intrinsic and extrinsic value, as well as the causes of their declines and the interventions needed to conserve them, in order to develop an argument for the importance of conserving and restoring pollinator populations and diversity. The present pollinator crisis threatens global and local food security, can worsen the problems of hidden hunger, erodes ecosystem resilience, and can destabilise ecosystems that form our life support system. An integrated approach that simultaneously addresses the key drivers is needed. This includes creation and restoration of floral and nesting resources, a global phase out of prophylactic use of neonicotinoids and fipronil, improvement of test protocols in authorisation of agrochemicals, and restoration and maintenance of independence in regulatory science. The authors argue that an international treaty for global pollinator stewardship and pollinator ecosystem restoration should be initiated in order to systemically counteract the current crisis.
