title: [Conduct of the oviposition of Aedes aegypti (L.) in the presence of Macrocyclops albidus (J.) and Bacillus thuringiensis var. israelensis under lab conditions].
abstract: The behaviour of the oviposition of pregnant females of Aedes aegypti in the presence of biological agents: Macrocyclops albidus (Copepoda: Cyclopoidea) or Bacillus thuringiensis var. israelensis (Bti) was evaluated under lab conditions. Recipients containing 225 mL of dechlorinated water were placed for oviposition with three variants: water with copepods, water with Bti, and water. The average of eggs layed in the recipients with copepods and Bti were 1 227.9 and 1 200.8, respectively, a figure higher than the 887.4 eggs of the recipient containing only water, although the differences observed were not statistically significant (p > 0.05). The Oviposotion Activity Index (OAI) estimated showed values over 0 for copepods and for Bti, which indicated that females did not avoid to deposit their eggs in these recipients. The results suggested that in nature, these recipients with biological controllers may be oviposition sites for pregnant females of Aedes aegypti, which may have positive implications on its effectiveness to control this vector.
