Abstract: The study examined the comparative impact of different spray regimes of cypermethrin and Neem Pro biopesticide in controlling Leucinodes orbonalis Guenee (Stem borer) of eggplant (Solanum aethiopicum) in Teaching and Research Farm of Agronomy Department, Delta State University, Abraka, Nigeria in 2022 and 2023. The experiment was laid out in a Randomized Complete Block Design with 5 treatments and replicated 3 times. The treatments consist of Cypermethrin (1 spray), Neem-Pro (1 spray), Neem-Pro (1 spray per week), Neem-Pro (2 spray per week) and Control. Leucinodes orbonalis, a key insect pest of eggplant was visibly present in all plots at 4 weeks before commencement of treatments application. L. orbonalis attack increased from week 4 to 8. Results indicated no significant difference between Cypermethrin and Neem-Pro at 1st spray before treatment application. Same was observed between Neem-Pro (1 spray per week) and Neem-Pro (2 spray per week). Treatment application at week 8 to 11 substantially reduced attack of stem borer. All treatments effectively reduced L. orbonalis attack and were significant different between all plots treated and control. Stem borer population increased from 12.8 to 17.3 at week 8 and week 11 respectively in control, while varied decreases in population under different spray regimes was observed. The biopesticides (Neem-Pro) is therefore recommended for control of L. orbonalis to eggplant farmers in area under studied for growing the plant.
