Shown above are the sticky wing trap catches for major insect species totaled for past several weeks to show relative activity of the moths. Pheromone traps are an excellent way to monitor moth activity in conjunction with actual crop scouting. Cold and wet spring seems to have delayed activity of most moths. We have very low activity of beet, fall, and southern armyworms in above locations where the traps were placed near commercial vegetable fields. This is typical since the armyworms become more active on vegetables later in the season after they have multiplied at other locations. We are finding increasing activity of corn earworm (tomato fruitworm) and tobacco budworms at few locations where we have multiple row and specialty crops – moth activity is slow but it is wise to start scouting the crops for small caterpillars that may look identical!

Squash vine borer traps have indicated downward trend over the past four weeks indicating that moth flight for the first generation is almost over and chances of finding larvae in squash vines is high (there could be a second generation if weather is favorable). Each female moth of the squash vine borer can lay up to 250 eggs and these are day flying moths. So stay alert and deter egg laying by mechanical means.

If the weather stays dry, we may see rapid increase in insect counts in our traps. We will be adding more insect monitoring sites in coming days, so stay tuned for more information! Visit the Alabama Vegetable IPM (www.aces.edu/go/87) or the Peanut IPM (www.aces.edu/go/88) websites for insect control recommendations for those crops. Consult a Regional Extension Agent for more detailed knowledge about integrated pest management practices suitable for your farm.
