The infection, which occurs in perianth, spreads to fingers causing blackening of the skin, shrinkage and folding of the tissues. In the advanced stages of disease, affected plants may have a spiky appearance due to prominent upright apical leaves in contrast to the skirt of dead lower leaves. Second stage juveniles emerge from the eggs, move towards the roots and penetrate the roots either at the root tip or in regions of previous penetration or where minor wounds are present.The eggs are laid within a gelatinous matrix to form an external egg sac or egg mass.

All these problems contributed to a new way of thinking concerning pest control practices, i.e. Yellowing of leaves and rusty growth over fruit. Infested plants lack vigour and fruiting is poor.                 Spiraling whitefly adults are small (2.0mm long), white and moth-like in appearance and mode of flight.
