Welcome to the Department of Entomology

For more than 125 years, our faculty members, staff and students have been working to advance the field of insect biology and apply that knowledge to solve problems and improve lives.

As one of the top-ranked entomology programs in the country, our work spans the globe and impacts human lives on many levels, influencing a broad range of disciplines including human and veterinary medicine, farming, biodiversity and genomics.

Onion growers put skin in the game, earn IPM award

Aug 5, 2019

Elba, New York onion growers, Matt Mortellaro, Guy Smith, Chuck Barie, Emmaline Long, and Mark and Max Torrey recently received an Excellence in Integrated Pest Management (IPM) Award from the New York State Integrated Pest Management Program (NYSIPM).

Conservation of the Sodium Channel between Different Insects is Explored

Jul 9, 2019

The voltage-sensitive sodium channel (VSSC) is essential for the generation and propagation of action potentials. The VSSC can change sodium kinetics by producing different splice variants (optional and mutually exclusive exons). The VSSC is the target site of pyrethroid insecticides as well as DDT and oxadiazines, which are used for control of crop pests and vectors of human diseases. Unfortunately, knockdown resistance (kdr) mutations in Vssc confer resistance to these insecticides. Recently, Silva and Scott 2019 investigated the conservation of VSSC by three approaches: (1) across insect Orders, (2) codon constraints of kdr mutations between populations of Aedes aegypti and (3) within a population of Drosophila melanogaster. Overall, VSSC is highly conserved across insects and within a population of an insect but important differences do exist. 

 

Insecticide resistance monitoring of House flies

Jul 9, 2019

House flies have evolved resistance to most insecticides, and as insecticide use continues over seasons it is expected that levels of resistance will rise. Freeman et al. recently investigated (https://www.sciencedirect.com/science/article/pii/S0048357519301282?via%3Dihub) flies collected from livestock facilities in five states to check levels of resistance against three commonly used insecticides. A population collected from Kansas had previously unseen high levels of resistance to permethrin, a pyrethroid insecticide, that could mean this type of insecticide will be of limited use for house fly control in the United States in the near future.
 

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.

Graphic warnings snuff out cigarettes’ appeal to kids

Nov 29, 2018
