Bottling predators ‘smell of fear’ to protect crops from insect pests [Full subscriber]

Researchers at Pennsylvania State University have developed a method that has enabled them to bottle the ‘smell of fear’ produced by the predator bugs, which acts to repel and disrupt destructive insects without using stronger pesticides.

Controlling insect pests through precision-guided genetics via CRISPR technology [Full subscriber]

Scientists at the University of California (UC) San Diego and UC Berkeley have developed a new approach to controlling disease-carrying or crop-destroying insects that uses CRISPR-Cas9-based genome editing to determine insect sex and fertility. The new technology, developed initially in fruit flies as a test case, represents a new take on sterile insect techniques (SITs) that have been used since the 1930s to mass produce and release sterile males as a strategy for eradicating insect populations.

Crop losses from global warming likely to hit the temperate zone most from insect pests [Full subscriber]

Researchers from several universities in the US claim that wheat, maize and rice yields (particularly in northern climates) are projected to fall as insects in temperate regions thrive in a warmer climate.
