Abstract
Campsis grandiflora (Thunb.), the Indian trumpet creeper, is commonly grown for ornament. In the present study, the aqueous extract of the leaves of the climber was evaluated for its pesticidal and insecticidal activities. A direct relationship was observed between the dose and the percentage larval mortality. Dosage values as expressed in log terms were, 1.398, 1.301, 1.230, 1.176 and 1.079 for 0.25, 0.20, 0.17, 0.15 and 0.12 ppm dose concentrations, respectively. For the insecticidal study, the percentage insect mortality was found to increase with the corresponding increase in dosage, indicating a direct relationship between the two. Highest insect mortality of 80% was observed with 5.75 µg/insect, while the lowest mortality of 20% was found, when the dosage was minimum at 0.35 µg/insect. Keywords: instecticidal, pesticidal, Campsis grandiflora Journal of Pharmaceutical and Allied Sciences Vol. 3(1) 2006: 274-277
