This research was aimed at evaluating the antimicrobial potency of abdominal extracts of a species of weaver ants ( Oecophylla longinoda ) on microorganisms found on kola nut pods. Ten (10) samples of five infected and five uninfected kola nut pods were got - ten from a farm in Ibule Community, Ondo State, Nigeria. Microorganisms were isolated from these samples using standard bacte- riological and mycological methods. These microorganisms were identified adopting a series of tests such as Gram staining, colonial morphology and biochemical characterization. The bacterial isolates obtained include Pseudomonas aeruginosa, Bacillus subtilis, Ba- cillus cereus, Bacillus polymyxa, Serratia marcescens, Klebsiella oxytoca and Aeromonas hydrophila . While fungal isolates were Rhizo- pus stolonifer, Aspergillus niger, Penicillium digitatum, Aspergillus flavus and Aspergillus fumigatus . Microbial isolates were subjected to antibiotic susceptibility testing by using Tetracycline (30 μg), Ofloxacin (30 μg), Gentamicin (20 μg), Chloramphenicol (30 μg), Augmentin (30 μg), Ceftriaxone (30 μg), Nitrofurantoin (300 μg), Cotrimoxazole (25 μg), Ciprofloxacin (10 μg) and Amoxicillin (30 μg), while the antifungal drugs used were Griseofulvin, Ketoconazole, Itraconazole and Clotrimazole. Pseudomonas aeruginosa was the most resistant bacterial isolate to commercial antibiotics, while it displayed a great level of susceptibility to the abdominal ex - tracts at the different concentrations tested. This research revealed that extracts from the abdominal region of Oecophylla longinoda possess antimicrobial activities beneficial for the protection of kola nut against pathogenic microorganisms.
