Summer seasonal pests have emerged including squash bugs and stink bugs. However, for the most part, population numbers are fairly low compared to other years. For squash bugs, controlling nymphs early, often, and with the right product is the key to managing their populations. Nymphs, just after hatch, are susceptible to insecticides but as they mature they grow out of their insecticide susceptibility. Economic thresholds are at least one egg mass per plant. When scouting, look for reddish/bronze colored eggs on the underside of cucurbit leaves. Products
Mike White reminded me that brown marmorated stink bug can be found now. This is the new invasive stink bug that is a nuisance pest for homeowners and many fruit and vegetable crops. It is not real common here in Iowa. However, Mike does regularly find it in Indianola and found it at the hort station recently. You might find it in vegetable fields or along buildings trying to seek winter shelter. StopBMSB is a great source for news and updates.
