* Control with pyrethroid insecticides may vary because of resistance in some populations of bean leaf beetles. This appears more common in the western region of the state, and particularly in the area near the Mississippi River Delta. Tank mixing acephate (0.5 lb active ingredient) with a pyrethroid insecticide will improve control.
- Early season infestations are often concentrated in the first emerging soybean fields in the area. These infestations will often subside once plants in other fields begin to emerge.
- Late season infestations are often worst in the latest maturing fields. Adults are very mobile, and reinfestations can occur quickly, reducing the efficacy of control.
