Overview

Randomized trial investigates biological parameters of C. bifoveolatus on fall armyworm across different plants, implying potential for biological control.

Key Points

  • The aim is to investigate the biological parameters of Chelonus bifoveolatus on Spodoptera frugiperda using different host plants throughout the year.
  • Conducted from April 2023 to February 2024 in Western Burkina Faso under ambient laboratory conditions.
  • Egg masses of S. frugiperda on maize, millet, and sorghum were exposed daily to female C. bifoveolatus to study the parasitism and developmental rates.
  • Parasitism rates ranged from 48% to 80%, with pupation rates between 48.00% and 99.43%.
  • Adult emergence rates varied from 27.60% to 84.91%, with development durations differing between wet and dry seasons.
  • The sex ratio favored males at a ratio of at least 2:1, and the adult lifespan averaged between 10.22 and 13.34 days.
