The study was carried out to evaluate the pesticidal properties of Azadirachta indica and Spondias mombin leaves against the activities of Phytolyma lata. The leaf extracts of Azadirachta indica and Spondias mombin were prepared using different solvents like methanol, chloroform and petroleum ether and were screened for their pesticidal properties. The results of the quantitative analysis showed that the leaves of both S.mombin and A.indica contained phenol, tannins, flavonoids, saponins, glycocides, steroids and alkaloids. Phytochemical screening of the bioactive compounds showed that the phenol, tannins, flavonoids, saponins, glycosides, steroids, and alkaloid contents of the leaves of S.mombinwas 1.00a ± 0.10, 3.80a ± 0.10, 2.98a ± 0.01, 7.40a ± 0.10, 0.02a ± 0.01, 1.27a ± 0.10 and 5.81a ± 0.01, while the leaves of A.indica contained 0.18b ± 0.01, 0.23b ± 0.01, 0.43b ± 0.01, 0.72b ± 0.01, 0.01a ± 0.01, 0.20b ± 0.00 and 1.38b ± 0.01 respectively. Both leaf extracts possessed the sampled bioactive compounds although in varying quantities. A study of the results obtained from both leaf extracts indicated that a higher quantity of bioactive compounds in S. mombin may be responsible for a more effective pest control than A. indica.
