Impact: Agriculture and Food Systems

Relevance 

In New York, most insect pest outbreaks are naturally suppressed by predators such as lady beetles. However, declines in native ladybug species have reduced biodiversity that supports effective biological control. Phloem-feeding pests, including aphids, cause significant economic damage to crops across the state. Increased reliance on chemical controls raises production costs and environmental risks. Small farms and home gardens can provide critical habitat for beneficial insects, yet many landowners lack guidance on how to attract and sustain ladybug populations.

Response

Cornell Cooperative Extension developed a community-based education and outreach program to support natural pest control through ladybug conservation. The program delivered workshops, educational materials, and hands-on demonstrations to gardeners, small-scale farmers, and community groups across New York. Participants learned how to identify native ladybug species, establish habitat with diverse plantings, and reduce practices that harm beneficial insects. The project also encouraged community monitoring efforts to track ladybug presence and pest activity.

Results

Participants increased their knowledge of beneficial insect conservation and adopted practices such as planting pollinator-friendly habitats and reducing pesticide use. Community members reported improved garden health and greater awareness of biological pest control methods. Observations from participants indicated increased sightings of ladybugs and reduced aphid infestations in managed spaces. The project strengthened local capacity to support sustainable pest management across small farms and residential landscapes.

Public Value

This project helps New York communities reduce reliance on chemical pesticides while promoting environmentally responsible pest management. By supporting native predator populations, the program contributes to more resilient agricultural systems, protects ecosystem health, and lowers costs for growers and gardeners. Expanding access to science-based guidance empowers residents to play a direct role in strengthening local food systems and environmental stewardship.
