Heliothine Trap Catches, June 4, 2021

Whitney Crow and I have placed pheromone traps for bollworm (corn earworm) and tobacco budworm in several Mississippi counties again this year and I will be reporting the catches weekly throughout the rest of the growing season. Coahoma county only has one set of traps this year, but catches from all other counties are the average per trap from 2-4 traps. Trap catches can vary widely from traps within a mile of each other, so moth pressure in any individual field may differ from the catches reported in this weekly blog. The purpose of these traps is to give people an early warning of when they may expect to see increased larval densities in their susceptible crops. These moth trap catches are NOT a substitute for field scouting, but can help make field scouting more efficient.

This week’s catches were average to lower than historical averages for both bollworm and tobacco budworm.
