Spiders – the creepy crawlers we need
There are plenty of creepy, crawly pests in the world, but spiders seem to take the top spot for the most terror-inducing specimens. Although your first instinct when you see one of these eight-legged creatures scuttling around is to stomp on it, you might want to reconsider. The population of spiders is on the decline, and that poses some serious problems for their biggest threat- humans. ...

Fipronil promotes motor and behavioral changes in honey bees (Apis mellifera) and affects the development of colonies exposed to sublethal doses
Bees play a crucial role in pollination and generate honey and other hive products; therefore, their worldwide decline is cause for concern. New broad‐spectrum systemic insecticides like fipronil can harm bees, and their use has been discussed as a potential threat to bees' survival. In the present study, the authors evaluated the in vitro toxicity of fipronil and noted behavioral and motor ...

Sachets ETHYL STOPPER, green alternative to SO2 use in organic grapes
The grape is a non-climacteric fruit which is highly sensitive to fungal infections, especially Botrytis cinerea. The most common treatment currently available to prevent these infections and maintain fruit quality is to fumigate with SO2 and use metabisulphite. Whilst these treatments are effective, they present a number of inconveniences: Development of stains and decolouring of fruit. ...

Insecticide risk map exposes threat to aquatic life
The global threat that insecticides pose for aquatic biodiversity has been revealed in a recent modelling study that pinpoints areas at greatest risk. The mapping exercise conducted by the researchers reveals that aquatic life in water bodies within 40 per cent of the global land surface is at risk from insecticides running off the land. Published in Environmental Pollution last month (30 ...

Effects of pyrethroid insecticides in urban runoff on chinook salmon, steelhead trout, and their invertebrate prey
Pyrethroid insecticides can affect salmonids either indirectly through toxicity to their prey or directly by toxicity to the fish themselves. In support of a study on pyrethroid impacts to Chinook salmon and steelhead trout in the American River (Sacramento, California), 96‐h EC50 and LC50 values for the pyrethroid bifenthrin were determined for taxa not traditionally used for toxicity testing ...

Case study - Neutralization basin odor control for agricultural chemical production
Challenge: An agricultural plant located in the Midwest manufactures herbicides, pesticides, fungicides, and insecticides. Strict environmental regulations require the company to capture and neutralize all surface runoff and grey water produced at the plant before disposing into the municipal system. In addition, air permits prohibit any odors to cross their fence lines. As the water collects ...

Environmental fate of emamectin benzoate after tree micro injection of horse chestnut trees
Emamectin benzoate, an insecticide derived from the avermectin family of natural products, has a unique translocation behavior in trees when applied by tree micro injection (TMI), which can result in protection from insect pests (foliar and borers) for several years. Active ingredient imported into leaves was measured at the end of season in the fallen leaves of treated horse chestnut ...

Assessment of interactive effects of elevated salinity and three pesticides on life history and behavior of southern toad (Anaxyrus terrestris) tadpoles
Because habitats are increasingly exposed to multiple stressors simultaneously, assessing the interactive effects of stressors is crucial for understanding how populations respond to human‐altered habitats. Salinization of freshwater habitats is increasing and has the potential to interact with other stressors. Chemical pollutants also contribute to habitat degradation in freshwater ...

Fate and effects of clothianidin in fields using conservation practices
Despite the extensive use of the neonicotinoid insecticide clothianidin, and its known toxicity to beneficial insects like pollinators, little attention has been given to its fate under agricultural field conditions. The present study investigated the fate and toxicity of clothianidin applied every other year as a corn seed‐coating at two different rates, i.e., 0.25 and 0.50 mg/seed, in an ...

Could evolution be our ally when it comes to mosquito control?
Two researchers propose a novel approach to reduce mosquitoes’ human toll without disrupting ecosystems. By the quirks of genetics, some people are natural mosquito bait. In any group of 10, it seems, one person will draw a fury of bites, while the rest get off lightly. Which makes a dreamer wonder: Why not devise a nonhuman target to attract mosquitoes and so reduce the toll of ...

Mowing mitigates bioactivity of neonicotinoid insecticides in nectar of flowering lawn weeds and turfgrass guttation
Systemic neonicotinoid insecticides are used to control of turfgrass insect pests. We tested their transference into nectar of flowering lawn weeds or grass guttation droplets which, if high enough, could be hazardous to bees or other insects that feed on such exudates. We applied imidacloprid or clothianidin to turf with white clover, followed by irrigation, and used LC‐MS/ MS to analyze ...
