"Mites - What have we learnt about them?"
The two-spotted spider mite, Tetranychus urticae, ranks second to Heliothis in importance as a pest of cotton. Mites reduce profitability by reducing the yield and fibre quality of cotton. In order to manage mites we need to know their seasonal pattern of abundance and what factors effect this, how to estimate their abundance, how damaging they are and when to control them. It is also essential to study the biology and ecology of the pest as this knowledge can improve the use of currently available controls and may lead to other non-chemical methods of management.
