Discussion

Field experiment shows biopesticides significantly reduce corn leaf aphid populations in maize, indicating eco-friendly pest management strategies.

The most effective biopesticide was Lecanicillium lecanii at 1.15% WP, reducing aphid populations effectively.
Biopesticides resulted in highest grain yield of 5523 kg/ha with L. lecanii treatment, showing their effectiveness in maize cultivation.
Integrating biopesticides helped maintain natural enemy populations, such as lady beetles, ensuring ecological balance.
Neem oil and neem seed kernel extract were less toxic alternatives, protecting beneficial insects while managing pests.

Parmar et al. (2025) studied this question.
