BALDERAS-PALACIOS, Gerardo Feliciano et al. Temporal and spatial distribution of mango white scale in Sinaloa, Mexico. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.spe19, pp.4023-4034. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i19.670.

A study was carried out in the mango producing area of Southern Sinaloa, Mexico, in order to determine the temporal and spatial distribution of the white scale of the mango Aulacaspis tubercularis Newstead (EBM). To obtain the population fluctuation of the scale, its presence for two years (2012-2014) was examined in the three main cultivars of Sinaloa: Ataulfo, Kent and Keitt. Geographic distribution was obtained by sampling mango orchards in the municipalities of Rosario and Escuinapa, Sin. During the two years, 221 commercial lots of the cultivars Ataulfo, Haden, Keitt, Kent, Manila and Tommy Atkins were sampled. Regarding the population fluctuation, the population densities of the scale varied between sampling dates during the year and among the evaluated cultivars. The population of A. tubercularis recorded three stages of development: during and after the rainy season (july-october) the population was the lowest. Low prevalence during low temperatures (november-february) and with the highest populations during the period of high temperatures and without rains (march-july). In relation to the spatial distribution, the white mango scale was recorded in 90% of the producing area of southern Sinaloa, in El Capomal municipality of Escuinapa, Sinaloa; ‘Manila’ was the most infested cultivar.
