MIRANDA, Ileana; BANOS DIAZ, Heyker; PEREZ ARANDA, Yadira y DE LOS ANGELES MARTINEZ, María. SPATIAL PATTERN AND GROWTH PARAMETERS OF Diaphorina citri KUWAYAMA AND ITS PARASITOID Tamarixia radiata Waterston ON Muraya paniculata. Rev. Protección Veg. [online]. 2011, vol.26, n.2, pp. 100-104. ISSN 1010-2752.
The spatial pattern and logistical growth of the Asian citrus psyllid Diaphorina citri Kuwayama and its main parasitoid Tamarixia radiata Waterston on the crop Muraya paniculata were studied to find out the correspondence of their spatial disposition, growth maximum capacity and intrinsic rate of increase. For it, weekly samplings were carried out in five points of the municipality Playa, Havana City. During two year (April 2007 - May 2009), five buds were randomly taken from three plants in each point and the D. citri densities evaluated. The parasite nymphs were observed until emerged adults of the parasitoid T. radiata when the density was also evaluated. Taylor´s index and Logistic model were used. Both populations presented an aggregate pattern; the maximum capacity was of up to an average of 268,01 individuals per sampling for the host and 76,5 for its parasitoid. The intrinsic rate of increase were 0,153 for D. citri and 0,088 for T. radiate, the psyllid found favorable condition to reproduce.
