RESUMO:

Soybean is a crop of great importance in the world and national scenario, responsible for much of the animal and human food, besides having a great potential for the manufacture of fuel such as biodiesel. However, there are several factors that negatively affect the good production of this oilseed, among these factors are the damage caused by insects, where one of the main is the whitefly. This pest causes direct and indirect damage to soybeans, the latter being characterized by virus transmission that harms many Brazilian crops. Thus, this work aimed to evaluate the whitefly infestation and the spatial distribution of this insect in its developmental stages (egg, nymph and adult), under field conditions, in Paragominas, PA, Brazil. The experiment was evaluated in three consecutive harvests, years 2015, 2016 and 2017, the first being held at the Federal Rural University Campus, making a weekly monitoring of the experiment. And the years 2016 and 2017 in the area belonging to the NAPT (Support and Technology Transfer Center) of Embrapa Eastern Amazon of Paragominas. The experimental design was randomized blocks in split-plot scheme (20 plots x 11 evaluations x 4 blocks), corresponding to the infestation evaluation of 20 soybean cultivars and 11 sampling dates at 07, 14, 21, 28, 35, 42. , 49, 56, 63, 70 and 77 days after emergence. For the descriptive analyzes, the variance (ANOVA) was performed by the F test (Fisher), and the means, when they differed significantly from each other, compared by the Tukey test at 5% probability. And for the geostatistical analysis we used the software SUFFER 7.0. The developmental year 2015 with the highest preference for whitefly was 56 days after emergence. In 2016, at 14 and 21 days after plant emergence, were the most favorable periods for the development of B. tabaci biotype B. In 2017 egg infestations at 7, 14, 21 and 35 DAE were at times of higher incidence of the pest.
