Abstract
IN an interesting letter (NATURE, May 3, 1930, p. 672) Mr. Kirkpatrick states that in the Gezira area (Sudan) an undetermined species of Aleurodidæ causes leaf-crinkle. In the Punjab (N.W. India) Bemisia gossypiperda, Misra and Lamba (Aleurodidæ), has been under observation during the last two years. This insect is present in enormous numbers but is not known to cause any deformation of the attacked leaves. Even in cages under conditions of a pure infestation of B. gossypiperda leaves literally covered on the under side with all the stages of the pest—eggs, nymphs, pupæ, and adults—remain quite flat and normal, and do not show curling, wrinkling, or crinkling. On the other hand, Empoasca devastans (Jassidæ) definitely causes leaf-crinkle.
