VINASCO A., Natalia; SOTO G., Alberto  and  VALLEJO E., Luis Fernando. THERMAL REQUERIMENTS FOR THE DEVELOPMENT OF Amblyseius sp. (ACARI: PHYTOSEIIDAE). Bol. Cient. Mus. Hist. Nat. Univ. Caldas [online]. 2014, vol.18, n.2, pp.61-66. ISSN 0123-3068.

Thermal requirements of Amblyseius sp. fed with Tetranychus urticae at five constant temperatures (17, 20, 24, 27 y 31°C) were studied. The stages of egg, larva, protonymph, deutonymph and adult egg corresponded to temperature thresholds of 12,6; 13,1; 11,6; 13,4 and 12,7 °C, and thermal constants of 26,6; 10,2; 16,1; 13,3 and 66,1 °D, respectively.

Keywords : mite; biology; thermal constant; phytoseiida.
