Predator preferences: a key to effective biological control design

Objetctive: This experimental study aimed to assess the preference of Gambusia affinis mosquito larvae An.gambiae s.s., Cx. quinquefasciatus and Aedes aegypti. Method: Three were introduced in a glass container with dimension 45cm x 25cmx 25cm. densities used, 90 (30 per species), 120 (40 180 (60 species). Each density experiment was set triplicate monitored after 1, 2, 3, 24 hours. No fish food added for larvae. Results: Results have shown that all times A. aegypti has been most preferred species by affinis. Among tested species, prayed time different densities. In mixed models including density, there no significant difference among predation. Conclusion: Preliminary results appropriate choice predators each can great impact on bio-control substantially complement existing tools.
