Overview

Randomized trial evaluates parasitoid efficacy against Aleurodicus dispersus in cassava and eggplant, suggesting enhanced biological control strategies.

Key Points

  • This study aims to assess how seasonal factors and specific traits of Encarsia spp. impact their effectiveness in controlling A. dispersus.
  • Field experiments conducted in a randomized block design with two parasitoid releases.
  • Pest populations monitored at regular intervals to evaluate control efficacy.
  • Morphometric analysis used to differentiate between parasitoid species.
  • E. guadeloupae achieved the lowest pest density, with the highest percent reduction of A. dispersus populations.
  • Second release led to greater suppression, indicating cumulative effects, particularly in March–April.
  • Distinct morphometric traits confirmed species identification, with E. guadeloupae being larger and E. meritoria having longer forewings.
