The pest status of the grey cluster bug ( N. clevelandensis Evans) and Rutherglen bug ( N. vinitor Bergroth) on cotton has, to date, been unclear. Under laboratory conditions we found that nymphs of both species fail to reach adulthood when fed cotton (tips or squares) alone, and adults are unable to reproduce on such a diet. In no stage of their development were bugs of either species able to damage seedling or early‐squaring cotton, even if no alternative food supply was provided. Our results therefore confirm that neither species is damaging to early‐season cotton.
