Insect behavior and control techniques

Arthropods were sampled in the upper 15-20 cm of cotton terminals using easily constructed beat and shake buckets. When compared to the visual examination method, the standard beat and shake procedure sampled 1.9-2.0× more arthropod predators, 2.3-5.3× more cotton fleahopper nymphs, 3.2-5.3× more small cotton leafworm larvae, and required 8-16% less time. Similarly, when compared to the beat procedure, the shake procedure sampled 1.2× more predators and 1.6× more small cotton leafworm larvae, but increased sampling time by 6%. Two other beat buckets were compared with the standard beat bucket and generally sampled either similar or slightly reduced numbers of arthropods. These sampling buckets have considerable potential for use in research and cotton pest management programs to sample arthropod predators and certain pest species.
