Dr. Stoner has expertise in developing alternatives to insecticides for managing vegetable insects, working with organic farmers and land care professionals on pest management, and studying the exposure of pollinators to pesticides in pollen and nectar.

Past Research:
Dr. Stoner’s research has identified a variety of possible alternatives to insecticides for managing insects in several different vegetable crops. One alternative is to grow varieties with resistance to insects, such as brassicas (cabbage, broccoli and related crops) that resist caterpillars due to differences in the waxes on their leaves. Another is the use of cultural methods, such as use of straw mulch on potatoes and eggplants, which increases the effectiveness of predators against the Colorado potato beetle. Another method she has studied is biological control of the Mexican bean beetle, using the parasitoid wasp Pediobius foreolatus. She has also participated as a member of the Northeast Organic Network in an intensive case study of organic vegetable and cash grain farms in the



Current Research:
Dr. Stoner’s research focuses on several aspects of bees and pollination:
1. Exposure of bees to pesticides in pollen and nectar, in collaboration with Dr. Brian Eitzer of the Analytical Chemistry Department
2. Attractiveness of ornamental plants to honey bees and native bees
3. Pollinator habitat on Connecticut farms and practices to create or improve habitat
4. Pollination of pumpkins and winter squash
