Abstract

The potential of aqueous and methanol extracts of ten botanicals were evaluated against the egg and adult of the spider mite Tetranychus truncatus Ehara, under laboratory conditions. The extracts showed no or negligible ovicidal action, but significant adulticidal action; among the aqueous extracts, A. squamosa (5, 7.5 and 10%), C. papaya (10%) and B. monnieri (10%) caused significantly maximum mortality, while it was methanolic extracts of A. calamus, C. papaya (1 and 2%) and A. marmelos (2%) which revealed maximum mortality with adults.
