The hot-and-cold temperatures this spring have delayed alfalfa weevil development throughout the state. We visited a field in Henry County, IA this week and noticed all sizes of larvae plus pupae. Take a sweep net to the field to see what's happening in your alfalfa fields. Also, note aphids and other potential pests. Sometimes, mechanical control (mowing) may be the most economical management tool. 

Between April 27 and May 3, 19 trap sites reported a total of 99 black cutworm moths captured in traps (Figure 1). There were two significant flights during the week (Figure 2), including Washington County on April 26 and Jackson County on April 28.
