RESUMOEurhizococcus brasilensis é a principal praga da videira no Brasil. O objetivo deste estudo foi avaliar a distribuição espacial de pérola-da-terra em pomar de Vitis vinífera em Vacaria, RS. As amostragens foram realizadas em 45 covas e os insetos organizados pelas frequências (insetos/unidade amostral), que foram submetidas aos índices de dispersão I, Morisita, parâmetro k da distribuição binomial negativa e b da lei de potência de Taylor. Observou-se ajuste das frequências obtidas à distribuição binomial negativa em todas as avaliações, mostrando que E. brasiliensis apresentou distribuição contagiosa no pomar. PALAVRAS-CHAVE: agregação, amostragem, pérola-da-terra. SPACE DISTRIBUTION OF Eurhizococcus brasiliensis (HEMPEL, 1922) (HEMIPTERA: MARGARODIDAE) IN VINEABSTRACT Eurhizococcus brasiliensis is the main grape pest in Brazil. The objective of this study was to evaluate the spatial distribution of ground pearl in Vitis vinifera orchard in Vacaria, RS. Samples were collected in 45 holes and insects organized by frequency (insects/sampling unit), which were submitted to the dispersion index I, Morisita, k parameter of the negative binomial distribution b of Taylor's power law. There was adjustment of frequencies obtained the negative binomial distribution in all evaluations, showing that E. brasiliensis showed contagious distribution in the orchard.

Spatial distribution studies of insect pests make it possible to determine their colonization and dispersal patterns. Watermelon (Citrullus lanatus (Thunb.) Matsum. et Nakai) is among the most frequently consumed fruits in the world, and the common blossom thrips, Frankliniella schultzei (Trybom) (Thysanoptera: Thripidae), is one of the most important insect pests of this plant. The objective of this study was to determine the spatial distribution of F. schultzei in commercial watermelon crops using geostatistics. The studied F. schultzei populations presented an aggregated distribution. The colonization of thrips began at the borders of the crops, especially in the areas located in the opposite direction to that of the prevailing winds. The highest densities of thrips occurred in crops that had cucurbits in the surrounding areas. When monitoring for F. schultzei populations, greater attention should be given to sampling that part of the crop located in the opposite direction to that of the prevailing winds because this is where colonization begins. Even at low densities, the aggregation points of thrips in the crop should be located and controlled so that they do not cause damage. In sampling programs for F. schultzei, samples should be taken at distances greater than 9 m apart because this is the distance up to which densities of this species show spatial dependence. Planting watermelon crops close to other cucurbits should be avoided, as these alternate hosts may act as a source of infestation by this pest.

Citrus BlackFly (CBF) always represented a threat to Brazil. The impact of the introduction in Brazil of the CBF has led to serious economic and environmental consequences. In this chapter, we will show relevant information on biological aspects, history of occurrence, and impact of CBF on Citrus in Brazil; data about dynamics populations and spatial distribution patterns and dependence will be presented. We are intending to emphasize in this chapter the main challenges and opportunities of some important tactics to promote sustainable management of CBF in citrus, such as: (i) biological control, (ii) chemical and others methods, and (iii) induced resistance.
