Plant produces large number of compounds as secondary metabolites with complex structure and diversity with a potent insecticidal activity. Large number of plants has been identified so far for their insecticidal property and can be used as an alternative pest management for synthetic pesticides. The present investigation was conducted to evaluate the insecticidal activity of prosopis juliflora against termite (Odontotermes obesus) and cockroach (Blattella germanica). The n-hexane extract of the proposed plant showed higher percentage mortality at 10 % concentration in 30 and 42 hours against termite and cockroach respectively. The LD50 was determined to be 0.472% and 1.07% for termite and cockroach, respectively after 23 hours. The proposed plant showed significant insecticidal activity at 0.005% level of confidence. From the present investigation it can be suggested that prosopis juliflora can be used as potential insecticide.
