Protecting gardens and crops from insects using the ‘smell of fear’

Herbivorous insects are a threat to gardeners’ hard work, and are increasingly resistant to pesticides. Today, scientists report they have bottled the “smell of fear” from predators to repel destructive insects without the need for harsh substances. They will present their results at ACS Fall 2021.

Announcing Virtual Press Conference for Experimental Biology 2021 Meeting

Reporters are invited to join a live Q&A discussion of exciting research announcements at the forefront of the life sciences during a virtual press conference for the Experimental Biology (EB) 2021 meeting. The press conference will be held online from 1–1:45 p.m. EDT on Monday, April 26, 2021 (RSVP by Friday, April 23).

Discovery: How Colorado Potato Beetles Beat Pesticides

New research shows that pesticide alter how Colorado potato beetles manage their DNA. These changes were passed down two generations suggesting that rapid resistance to pesticides may not require beetles to evolve their genetic code. Instead they may simply use existing genes to tolerate toxins already found in potatoes. The scientists were surprised that these epigenetic changes, triggered by a single tiny dose of pesticide, were maintained through multiple rounds of sexual reproduction.

Imitation Mosquito Ears Help Identify Mosquito Species and Sex

Using an imitation “ear” modeled on the organs that mosquitos use to hear, researchers have identified a mosquito’s species and sex using sound — just like mosquitos do themselves. The researchers hope this bioinspired detector could someday be used in the field to save lives by aiding in more selective pesticide use and possibly preventing mosquitos from mating. A presentation of the new research will be given as part of the 179th ASA Meeting.

As Evidence of “Hormone Disruptor” Chemical Threats Grows, Experts Call for Stricter Regulation

A growing number of chemicals in pesticides, flame retardants, and certain plastics have been linked to widespread health problems including infertility, diabetes, and impaired brain development, a set of reviews of hundreds of studies concludes.
