Abstract

Low concentration of raw flower juice of Calotropis porcera (Asclepiadecae) and seed dust of Nerium oleander (Apocynacae) significantly delayed the egg to adult development of two-spotted spider mite, Tetranychus urticae Koch, for three successive generations under laboratory trial. The flower juice of C. porcera was found more effective than the seed dust of N. oleander in delaying the developmental period of TSSM.

Key words: C. porcera, N. oleander, T. urticae, TSSM, developmental period.
