Sweet corn trapping data is updated by Tuesday and Friday mornings and can be accessed here: http://agdev.anr.udel.edu/trap/trap.php. As we suspected last week, trap captures have plummeted in part, I am sure, because we are trying to capture sizeable earworm moths for pyrethroid resistance monitoring. We typically experience a lull in moth activity until mid-July. Trap catches are as follows:
| Trap Location | BLT – CEW | Pheromone CEW | Corn spray schedule |
| (3 nights total catch) | |||
| Dover | 1 | 3 | 5 day |
| Harrington | 1 | 0 | No spray |
| Milford | 0 | 0 | No spray |
| Rising Sun | 0 | 15 | 4 day |
