A web-based, apple Integrated Pest Management (IPM) decision support system was developed to facilitate pest management decisions. The system tracks seasonal development of insect pests using degree day (DD) developmental models. DD models and historical records are used to calculate tree phenological stage, pest stage, status and management advice. When a spray is recommended, a pesticide filter helps identify appropriate materials according to efficacy and type of management program. Predictions can be refined and adjusted by user-entered information obtained through field monitoring.

The neural networks that organize the motor pattern for locomotion are located in the spinal cord. These networks normally receive descending inputs from the brain that activate them and direct them to modify their output for variable behavior. These inputs are lost after spinal cord injury (SCI). As a consequence, the neurons begin to change their properties, in ways that might be deleterious to eventual recovery from SCI.

We are studying the patterns of attack by a community of insect herbivores on plants; the work involves field biology, chemical ecology, genetics, and entomology. Our basic research involves milkweed plants, nearly 120 species from North America (and 20 from South America), which grow in various habitats and are attacked by a specialized community of insects. Some of the work is evolutionary in terms of quantifying phylogenetic patterns associated with the evolution of specialization (in insects parasites) and other work is more ecological, based on community interactions.

2009 to 2012

Spinal cord injury (SCI) results in two spinal problems. First, the neural networks that control movement in the spinal cord lose their drive from the brain. Second, the neurons in the spinal cord below the lesion start to alter their properties due to the loss of input. We are studying this second problem by analyzing the properties of identified spinal interneurons after spinal cord injury, and whether replacement therapy with serotonergic agonists can prevent these changes.

New York has great potential to expand the cultivation of sustainable, perennial crops for the production of woody biomass—for heat and bioenergy and as a feedstock for biofuels—on under-used agricultural land.

2009

Cornell Cooperative Extension educators increasingly find it challenging to make meaningful connections in a “too busy” world. In addition, they rarely have opportunities to engage with Cornell undergraduate. This is unfortunate for the educators, who benefit from the innovative engagement with the students, and for the students, who benefit from the real world connections and mentoring opportunities offered by interacting with educators.

2009 to 2015

Production of fruits and vegetables requires animal, primarily bee, pollination. While honey bees are widely used for crop pollination, honey bee populations are in decline due to a combination of factors, including heavy pathogen load and pesticide use. Native bees—wild bees that occur naturally in the environment surrounding agricultural areas—are contributing significantly to crop pollination, but it is difficult to estimate their exact contribution, and limited resources exist for farmers who want to preserve their native bee fauna.

2009 to 2014

Alfalfa is a major economic crop in New York. It is often grown in rotation with corn where, on dairies, manure is applied to corn fields to meet nitrogen needs and build potassium, phosphorus, and sulfur levels. Questions arise related to the potassium and sulfur needs of alfalfa, given high fertilizer prices and reduced sulfur deposition.

2008 to 2013

Three 3-year fellowships will help train plant breeders to use modern techniques to improve the abundance and safety of the U.S. food supply in a sustainable way.

2008

Through our outreach efforts we have attempted to raise awareness among the general public and policy makers, such as the New York State Department of Health, about the issues and complexity of the West Nile virus (WNV) transmission cycle. Our research to date has provided new ideas and methods for prevention and control of these medically important mosquitoes. This information may contribute to public knowledge in New York state about how to avoid infection and reduce dangerous mosquito populations on private property.
