Insect Update - June 2008

June 17, 2008

Normal summer for insects? So far, despite the dramatic swings up and down in our weather, we seem to be on track for normal timing for most of our typical turfgrass insect pests. Japanese beetle and other grub species will probably appear on schedule as we are seeing typical timing for the emergence of the adults which lay the eggs. The same is true for mole crickets near the coast. The four or five days of hot weather certainly gave southern chinch bugs a jump start on St. Augustinegrass, so keep a close eye on it for the rest of the summer. Watch for small areas of turfgrass that turn yellow or tan.

No predictions on fall armyworms yet for this summer. We've not had a lot of storms come in from the south, but it only takes one to get them here and give them a shot at getting started. They should have arrived in the state by now. It’s just a matter of how long it will take for them to build up. Remember, they are the most serious problem in newly-seeded areas, newly-sprigged areas, and newly-sodded sites. Keep an eye out for them!
