ABSTRACT

The objective of this study was to determine the effects of rainfall, temperature, predators, plant age, leaf chemical composition, levels of leaf nitrogen and potassium besides density of leaf trichomes on attack intensity of Frankliniella schulzei on the Cucumis sativus. An increase in the number of thrips was observed with plant aging. Higher number of this insect was verified in the apical part than in the middle and bottom part of the plants canopy. Pentacosane positively affected thrips. Rainfall, temperature, predators, levels of leaf N and K, and leaf trichomes did not effect thrips populations on cucumer plants.
