TL;DR: How neonicotinoids interact with the nervous system of honeybees and affect individual honeybees in laboratory situations is described and a review of current and proposed guidance in the United States and Europe for assessing the risks of pesticides to honeybees is concluded.
Abstract: The European honeybee, Apis mellifera, is an important pollinator of agricultural crops. Since 2006, when unexpectedly high colony losses were first reported, articles have proliferated in the popular press suggesting a range of possible causes and raising alarm over the general decline of bees. Suggested causes include pesticides, genetically modified crops, habitat fragmentation, and introduced diseases and parasites. Scientists have concluded that multiple factors in various combinations—including mites, fungi, viruses, and pesticides, as well as other factors such as reduction in forage, poor nutrition, and queen failure—are the most probable cause of elevated colony loss rates. Investigators and regulators continue to focus on the possible role that insecticides, particularly the neonicotinoids, may play in honeybee health. Neonicotinoid insecticides are insect neurotoxicants with desirable features such as broad-spectrum activity, low application rates, low mammalian toxicity, upward systemic movement in plants, and versatile application methods. Their distribution throughout the plant, including pollen, nectar, and guttation fluids, poses particular concern for exposure to pollinators. The authors describe how neonicotinoids interact with the nervous system of honeybees and affect individual honeybees in laboratory situations. Because honeybees are social insects, colony effects in semifield and field studies are discussed. The authors conclude with a review of current and proposed guidance in the United States and Europe for assessing the risks of pesticides to honeybees.

TL;DR: CPY is an important tool in management of a large number of pests (mainly insects and mites) and is used on a wide range of crops in the U.S. from 2008 to 2012 and is potentially toxic to most animals.
Abstract: The physical and chemical properties of chlorpyrifos (O, O-diethyl O-3,5,6-trichloro-2-pyridinyl phosphorothioate, CPY; CAS No. 2921-88-2) are the primary determinants that govern fate (movement, adsorption, degradation, and catabolism) in the environment and in biota. The uses of chlorpyrifos in locations of interest, such as the United States in the case of this paper, are the primary determinants of the entry of chlorpyrifos into the environment and its subsequent fate in the regions of use and beyond. The uses and manner of use are addressed in this paper.

TL;DR: This exploratory, mixed-methods study examines the relationship between community attitudes toward LGBTQ persons and associated community responses to LGBTQ sexual assault victims.
Abstract: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals encounter social conditions that create important considerations for LGBTQ sexual assault victims. This exploratory, mixed-methods study examines the relationship between community attitudes toward LGBTQ persons and associated community responses to LGBTQ sexual assault victims. An online and paper-and-pencil survey (n = 130) and four focus group interviews (n = 14) are analyzed using frequency distributions and grounded theory methods. The central theme that emerged in focus group interviews, titled "low community awareness and support for sexual violence in the LGBTQ community," was corroborated by survey participants. Participants' views of unique considerations for LGBTQ sexual assault victims are presented, including causal factors, consequences, and recommended strategies.

TL;DR: The use of CPY in agriculture in North America does not present an unacceptable risk to honeybees, and compliance with the label precautions and good agricultural practice with the product is the norm in North American agriculture.
Abstract: Pollinators are crucial species of almost all natural and artificial terrestrial ecosystems (Garibaldi et al. 2013; NAS 2007). While most of the world’s food supply, including important crops such as cereals, are mainly wind pollinated, more than three-quarters of angiosperms rely on animals for pollination and approximately 75 % of the leading global fruit-, vegetable-, and seed-crops depend at least partially on animal pollination. Most animal pollination is done by insects, particularly bees. In the United States (US) and Canada, the production of crops that require or benefit from pollination by insects is large. It is estimated that the pollination services of the European honey bee, Apis mellifera L. (Aide), are worth over $15 billion annually to US agriculture, and the value of non-Apis pollinators to production of crops is estimated to be over $11 billion. In addition to helping ensure a diverse supply of food for humans, pollination plays a critical role in providing the basis for essential ecosystem productivity and services

TL;DR: This volume of Reviews of Environmental Contamination and Toxicology is devoted to an assessment of the ecological risks posed by chlorpyrifos (O,O-diethyl O-(3,5,6-trichloro-2- pyridinyl) phosphorothioate; CPY) as used in the United States.
Abstract: As explained in the foreword, this volume of Reviews of Environmental Contamination and Toxicology is devoted to an assessment of the ecological risks posed by chlorpyrifos (O,O-diethyl O-(3,5,6-trichloro-2- pyridinyl) phosphorothioate; CAS No. 2921-88-2; CPY) as used in the United States (U.S.). CPY is a widely used organophosphorus insecticide that is available in a granular formulation for treatment in soil, or several flowable formulations that can be applied to foliage, soil, or dormant trees. CPY can be applied by use of aerial spraying, chemigation, ground boom or air-blast sprayers, tractor-drawn spreaders, or hand-held equipment.
