This paper reviews initiatives for conserving insects and argues that they must be expanded globally to protect insect populations. It also argues that the value of insects to society must be better communicated to people, e.g. through focusing on the benefits of iconic insect species or particular landscapes.
This paper quantifies the economic impact of herbicide resistance developed by the weed Alopecurus myosuroides (black-grass). It finds that the annual cost of this resistance is £0.4 billion each year in England, based on lost profit from lower crop yields. The global cost of herbicide resistance could be much higher, as there are 253 known herbicide-resistant weeds.
This book gives details of methods for detecting and dealing with various agrochemicals, including herbicides, insecticides, fungicides and soil fumigants.
This paper finds that neonicotinoid use in rice paddies surrounding Lake Shinji in Japan was followed by a collapse in the fishery yields of smelt and eel, likely due to neonicotinoids reducing the abundance of zooplankton on which smelt and eels feed. The paper suggests that similar fishery yields decreases in lake across Japan could be linked to neonicotinoid use.
This report, commissioned by the Wildlife Trusts (a group of UK charities), summarises existing evidence on declines in insects, many types of which have substantially decreased in abundance since 1970 (see for example Worldwide decline of the entomofauna: A review of its drivers). It also explores the drivers of these declines and calls for an urgent halt to “all routine and unnecessary use of pesticides”.
The initial results of an experiment on palm oil plantations in Sumatra, Indonesia, suggests that using less fertiliser on palm oil plantations and controlling weeds through mechanical weeding instead of herbicide use could be beneficial both ecologically and economically.
This feature in the New Food Economy explores how autonomous weed-picking robots could replace herbicides and tackle weeds that have become resistant to some herbicides. The robots use both GPS tracking and cameras to navigate fields and remove weeds.
This report by the US non-profit Environmental Working Group analyses pesticide residue data from the US Department of Agriculture. It concludes that around 70% of produce in the US is sold with pesticide residues, with particularly high levels in strawberries, spinach and kale and relatively low levels in avocados, sweetcorn and pineapples.
Over 40% of insect species are at risk of extinction over the next few decades and 75% to 98% of insect biomass has already been lost, according to this review of the current state of knowledge about insect declines, with habitat loss through conversion to intensive agriculture being the main driver. Agro-chemical pollutants, invasive species and climate change are also driving insect declines.
This book discusses options for sustainable weed control for a variety of crops. Topics covered include the impacts of herbicides on people, soils and ecosystems, integrated weed management, and herbicide resistance.
Switching to an organic diet for six days significantly reduced the levels of several pesticides and pesticide metabolites found in the urine of the 16 participants of this study.
The Food Research Collaboration continues its series on Brexit (for our non-UK readers, the UK’s upcoming departure from the European Union) with an exploration of the paths that UK pesticide regulation could take: either deregulation and allowing greater pesticide use, or strengthening of regulations in line with or beyond those of the EU.
This paper describes the susceptibility of organisms such as bacteria to biocides such as antibiotics, insecticides and herbicide as a beneficial ecosystem service, since susceptible organisms can prevent the spread of biocide resistance by outcompeting resistant organisms (that is, in biocide-free environments). This framing is distinct from many other viewpoints, which focus on the negative costs of biocide resistance.
Researchers have called for governments to phase out organophosphate pesticides in agriculture, ban their non-agricultural uses, and take steps to reduce human exposure to organophosphates. The researchers’ argument is based on systematic reviews that link foetal organophosphate exposure to adverse effects on the development of children’s brain and nervous system.
The common weed killer glyphosate targets an enzyme only found in plants and microorganisms. However, a new paper finds that glyphosate can harm honey bees even though they lack the targeted enzyme. Glyphosate does this by changing the balance of microorganisms (some of which contain the relevant enzyme) found in the bees’ guts, making the bees more susceptible to infections.
