BANOS DIAZ, Heyker L; MIRANDA, Ileana  and  MARTINEZ, María de los A. Biology and life table of Tamarixia radiata Waterston under controlled conditions. Rev. Protección Veg. [online]. 2013, vol.28, n.2, pp. 120-126. ISSN 1010-2752.

With the aim of determining the duration of the life cycle, survival, sex ratio, longevity, fecundity and other biological and population attributes of Tamarixia radiata Waterson, it was reared on Diaphorina citri Kuwayama on Muraya paniculata (Jack) plants at 70±10% of HR, 28±1p C and 14 :10 LD. The period of pre-mummification and the development cycle was of 3,08 and 7,27 days, respectively, for a total life cycle of 25,62 with a survival of 18,35 days. The parasitism exceeded 70% with an emergence of 72,27%.On the oher hand, the rate of oviposition was 24 eggs / female / day, and a longevity of 23 days, which was higher in females. The time of fecundity for the T. radiata female was 0,94 days and the reproductive growth rate of 333,77 eggs/day. The population parameters such as the intrinsic rate of increase (r_m) and the finite rate of increase (l) showed values of 0,14 and 1,02 respectively, and the net reproductive rate (R₀) had an estimated value of 1,55 (daughters female/female mothers). These parameters were compared with those of its host D. citri, and they reaffirmed T. radiata as a potential biological control.
