This year's fall armyworm pheromone trap captures at the Lubbock Research and Extension Center are at historic lows for the eight years we have been operating the traps. There are no technical problems with the pheromone lures, and we have plenty of corn near the traps to attract moths.
Of course the big question is why fall armyworm is mostly a no-show this year. We discussed this among Extension Entomology personnel on the High Plains and can't come up with a solid answer. There are plenty of moths on the Gulf Coast, we have the normal number of host plants, and we had a mild winter. Even thought I can't explain it, I am confident that this phenomenon is real and it is good news for our whorl stage corn and sorghum.
