Abstract

                                Rectangular yellow sticky trap was most effective for monitoring the adult whitefly, Bemisia tabaci Genn. in cotton. Stick-gum (poly-isobutane) and castor oil were effective in trapping the attracted adults. increasing the trap height was effective with the plant growth. The traps facing the sky and placed horizontally either inside or adjacent to the cotton field attracted more whiteflies. It was established that yellow sticky traps can be used for predicting the incidence of whitefly. A positive correlation was observed between trap catches and number of eggs in the field.

Key words : Cotton whitefly, Sticky trap.
