ABSTRACT

Seasonal abundance of fleahoppers and Lygus varied with cotton cultivar as well as the planting date window. Paymaster 2326RR had the most fleahoppers and Lygus compared with Stoneville 2454R, Paymaster 2145RR, and Paymaster 2167RR. Late-planted cotton attracted significantly more of both species compared with the timely planted cotton. Sampling methods varied in their efficiency to capture fleahoppers and Lygus. The beat bucket method captured significantly more Lygus, while the visual method accounted for the most fleahoppers compared with other sampling methods.
