My research work is oriented to analyze the factors affecting adult populations of spittle bugs, Aenolamia and Prosapia species. I sampled several sugarcane plots infested with this pests during 2014. I am analyzing how precipitation, temperature, weed coverage, insecticide applications and other factors influence the populations of spittle bugs. I am using a mixed model in R to assess these factors and to estimate the spatial disposition of adult and nymph populations.
