abstract
The leaves of neem (Azadirachta indica), notchi (Vitex negundo), pungam (Pongamia pinnata) and eucalyptus (Eucalyptus globulus) were shade dried, powdered and admixtured at the dosage of 250 and 500 mg along with the standard checks viz., malathion 25% WP (5 mg) and deltamethrin 2.5% EC (2 µl) per 50 g of cured turmeric rhizomes. The highest percent mortality was observed in notchi leaf powder 500 mg (68.15%) followed by neem leaf powder 500 mg (66.16%), notchi leaf powder 250 mg (60.65%), eucalyptus leaf powder 500 mg (60.19%), eucalyptus leaf powder 250 mg (55.22%), neem leaf powder 250 mg (53.72%), pungam leaf powder 500 mg (47.26%) and pungam leaf powder 250 mg (43.77). The minimum number of 4.60 adults were emerged in notchi leaf powder 500 mg followed by neem leaf powder 500 mg (4.94 adults), eucalyptus leaf powder 500 mg (6.05 adults), neem leaf powder 250 mg (6.10 adults), notchi leaf powder 250 mg (6.16 adults), pungam leaf powder 500 mg (8.77 adults), pungam leaf powder 250 mg (10.27 adults) and eucalyptus leaf powder 500 mg (10.44 adults). It was evident that, notchi leaf powder 500 mg was found to be best among the plant products tested, since it caused maximum mortality and adult emergence.
