Understanding the causes of insecticide resistance in Aedes aegypti

Mar 13, 2019

 
Cytochrome P450 monooxygenases (CYPs) carry out the detoxification of insecticides, and overexpression of one or more CYPs is a common mechanism of insecticide resistance in mosquitoes. Smith et al. investigated the molecular basis for CYP-mediated resistance in A. aegypti and found that overexpression of the CYPs responsible for resistance was due to a trans-regulatory factor.  Read more

Insecticide resistance in Drosophila melanogaster and sour rot

Mar 5, 2019

Control of sour rot in grapes is commonly achieved using insecticide to control D. melanogaster.  2018 was one of the worst years for sour rot in grapes in New York in decades. Sun et al. report that the outbreak of sour rot at one NY vineyard was associated with an inability to control D. melanogaster due to the evolution of resistance.  Read more

Pollinator Network

Pollinators are essential for maintaining floral diversity and for producing many important agricultural crops that feed residents of New York and other areas of the world. 

Cornell University has a robust network of pollinator research and extension program related to all aspects of pollinator life: Ecology, Evolution, Biodiversity, Behavior, Pesticides, Pests, parasites, and disease, Pollinator management.  Explore the Cornell Pollinator website for information on bee research taking place at Cornell, news and upcoming events, and for a variety of extension materials related to pollinators and beekeeping.

Engaged Entomology

EOA students Mike Wolfin and Zach Cohen have been visiting local schools educating students about different insects and arthropods while Joanna Fisher has been visiting with groups like 4H, Master Gardeners, Master Naturalists, Master Forest Owners, EAB First Detectors trying to teach the public how to identify invasive species like emerald ash borer, hemlock woolly adelgid, and Asian longhorned beetle.

The Naturalist Outreach group has been visiting local classrooms and community groups to talk about the natural history, ecology, and behavior of animals and plants.  They have also created a series of videos teaching the public about an array of issues from pollination to bats to aquatic insects and more.  This group is not only teaching but trying to inspire and engage more people into science.

Insectapalooza is a one day insect fair held annually by the department bringing in families from as far as Michigan each year.  This event reaches thousands of visitors who get hands on experience learning about many different arthropods, their importance and benefits to our community.

Emprire Farm Days and the New York State Fair are two other annual events attended by the Department of Entomology where large groups of people are reached.
