Question of the Week: Bean Leaf Beetle

Last week the question was:  What are these insects found in a soybean field?


These are bean leaf beetles.  These beetles can be found pretty commonly in soybean fields throughout the growing season.  They prefer to feed on tender new leaves.  We don’t see them cause trouble very often, but if large numbers build up, treatment decisions should be made based on the foliage loss thresholds (30% pre-bloom and 15% after bloom) found in the SC Pest Management Handbook.


Here is this week’s question:  What happened to this sweet potato vine?
