Abstract: -The spatial distribution of insects is essential to perform control strategies, to improve sample techniques and to estimate economic losses. We aimed to determine the spatial distribution of nests of Acromyrmex crassispinus (Forel) in Pinus taeda plantations. The experiments were carried out in P. taeda plantations with different ages (treatments: recently-planted, three and six-year old plants). The study took place in Rio Negrinho and in Três Barras, SC. Three plots of one hectare were delimited in each t… Show more

“…The spatial distribution of A. crassispinus nests was random in most samples, similar to that described in Nickele et al (2010). The random distribution of leaf cutting ants also had been documented by Zanuncio et al (2002), Caldeira et al (2005) and Cantarelli et al (2006).…”

“…The total sampling area (30,000 m 2 ) was subdivided into 192 sampling units of 156.25 m 2 , based in Nickele et al, 2010. The data of the location of A. crassispinus nests in each evaluation were tested to see if they fitted Poisson's distribution (that represents the random spatial distribution), positive binomial distribution (that represents the regular spatial distribution) or negative binomial distribution (that represents the aggregated spatial distribution), following the expressions, as Bliss and Fisher (1953), Davis (1993) and Krebs (1989).…”

“…Índice de dispersión de Morisita ( Iδ ) : desarrollado con el objetivo de presentar un índice independente de la media muestral y del número total de individuos. Valores próximos a la unidad indican una distribución aleatoria, valores superiores a uno indican distribución agregada, y valores inferiores a uno indican una distribución regular o uniforme (Fernandez et al, 2003;Nickele et al, 2010). Este índice es estimado por:…”

“…The importance of insect control has also encouraged researches focused on statistical modeling of the spatial distribution of nests (Doncaster, 1981;Croft & Hoyt, 1983;Caldeira et al, 2005;Nickele et al, 2010;Gao, 2013;Sousa-Souto et al, 2013). It allows the development of better ant bait distribution strategies through more appropriate sampling plans than common basic standardization applied in most Brazilian plantations (Nickele et al, 2013;Bollazzi et al, 2014;Reis et al, 2016).…”
