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.
Researchers at Johns Hopkins Bloomberg School of Public Health have shown in a brain organoid study that exposure to a common pesticide synergizes with a frequent autism-linked gene mutation.
Scientists are looking at ways to make more of this natural pesticide
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).
A UCLA-led study published in the peer-reviewed journal Environmental Research suggests that exposure during pregnancy to a wide variety of pesticides may lead to the development of central nervous system tumors during childhood.
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.
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.
2D Electronics, Plant Biofactories, Transforming Waste, and Vaccine Development.
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.
Using integrated pest management to decide if pesticide is warranted
An ounce of preparation in the spring for a summer of garden bounty.
A newly published study sheds light on how insecticides commonly applied to crops affect monarch caterpillars. Conservation efforts to protect monarch butterfly populations depend on planting milkweed on agricultural land, but doing so may put caterpillars in close proximity to harmful insecticides.
In the wake of the Environmental Protection Agency’s recent release of interim decisions on glyphosate and neonicotinoids, chemicals used in agriculture that have been linked to adverse effects, Former advisor to the EPA’s Office of Pesticide Program and Clinical Professor…
Adverse outcomes from childhood exposures to lead and mercury are on the decline in the United States, likely due to decades of restrictions on the use of heavy metals, a new study finds.
