Insect Pest Monitoring in Arkansas

This interactive map of Arkansas shows locations of various insect trapping efforts by Extension Specialists and County Agents. When a location is clicked, the map will populate with insect trap data for that region to help indicate pest presence or absence. You can zoom in and out using the map features on the top left of the map. Additionally, click the >> arrows to access the map Legend. We are now monitoring for Melonworm (Diaphania hyalinata), Squash Vine Borer (Melittia cucurbitae), Cabbage Looper (Trichoplusia ni), Tomato Fruitworm Moth (Helicoverpa zea), and many other pest species in fruit and vegetables for the 2023 growing season, so check back often! The larger dots indicate areas we have observed Melonworm this Fall.

Growing Degree Days (Base 50°F, beginning January 1)

With recent warm weather we are at the time when squash vine borer emerge. We expect to see adult moths at 750-1000 GDD (Base 50°F). Now is a good time to scout your fields for eggs. We have currently stopped recording GDD because all of the state has accumulated enough GDDs to be at risk.

GDDs as of 5/25/2023

Kibler - 1370

Clarksville- 1112

Hope- 1414

Little Rock- 1562

Fayetteville- 1093
