Spatial pattern and distribution inside the plant Pseudacysta perseae Heidemann (Hemiptera: Tingidae) in avocado trees associated to coffee plantation

, : Spatial pattern and distribution inside the plant Pseudacysta perseae Heidemann (Hemiptera: Tingidae) in avocado trees associated to coffee plantation. Revista de Proteccion Vegetal 20(3): 173-178

A research was carried out to determine the spatial pattern and distribution of P. perseae (Hemiptera: Tingidae) in avocado trees associated to coffee plantations. The dispersion indexes such as variance-mean ratio, index of mean crowding, the Lloyd's index, the Green's index and the exponent k of the negative binomial distribution were calculated to describe the spatial pattern.
