Student Job

Aug 22, 2019

The laboratory of Dr. Ann Hajek in the Department of Entomology studies insect pathogenic fungi and nematodes as biological control agents for notorious invasive insect species such as the Asian longhorned beetle, gypsy moth, brown marmorated stink bug, and spotted lanternfly.
Laboratory assistants will care for insect colonies, collect live insects from rearing cages and the field, dissect insects to look for pathogens, and use sterile technique to culture organisms.
The successful candidate(s) will pay strong attention to detail and follow instructions, but also may assist in problem-solving and developing new methods. Must have excellent communication skills and work well with others. Must be willing to work indoors and outdoors, and infrequently lift heavy objects.  Must be physically able to use microscopes.  Preference given to students who have held a Driver’s License for 3 years prior to employment.  (Personal vehicle NOT required.) 
Assistants are scheduled for 6-10 hours per week.  This position requires a commitment to sometimes work independently for on Saturdays and/or Sundays, depending on the experiments that are ongoing. To apply, send a cover letter and resume to both Dr. Eric Clifton ( and David Harris (

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. 


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.

Study: Red or blue, Americans value effort to achieve success

Aug 7, 2019

According to new Cornell-led research exploring the foundations of morality, liberals and Democrats are far more inclined than conservatives and Republicans to believe in the importance of equity – the notion that some groups may need different opportunities to succeed based on their starting points, so that all have the same levels of success.
