Última Imidacloprid impact on arthropods associated with canopy of common beans Neotropical Entomology Marquini,Flávio; Picanço,Marcelo C.; Guedes,Raul N.C.; Ferreira,Paulo S.F.. The present work aimed at assessing the temporal and spatial effect of applying the insecticide imidacloprid on the arthropod community associated with the canopy of common beans (Phaseolus vulgaris). About 2 ha of bean field was divided into two adjacent fields subjected to the same crop management practices except for insecticide application. Imidacloprid 700 GrDA (147 g a.i./ha) was applied to 20-day old plants. Three transects were extended from the mid-part of the sprayed area to the mid-part of the non-sprayed area. Nine sampling points 10 m apart were established in each transect. Arthropods were sampled from the plant canopy before and 3, 8, 14, 22, 29 37 and 44 days after insecticide application. There was a strong temporal effect of the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Insecta; Neonicotinoid; Environmental impact; Phaseolus vulgaris.

Leaves Ciência e Agrotecnologia Leite,Germano Leão Demolin; Picanço,Marcelo; Jham,Gulab Newandran; Marquini,Flávio. The objective of this study was to determine the effect of height of leaves in the canopy of plants, leaf organic compounds, concentrations of leaf nitrogen and potassium, leaf trichomes and cristalliferous idioblasts densities on the attack intensity of three tomato (Lycopersicon esculentum Mill. cv. Santa Clara) crops by Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and Liriomyza spp. (Diptera: Agromyzidae), under field conditions. The experimental design was arranged in randomized blocks, with three replications, each being one tomato crop. Analysis of variance and the Tukey’s multiple range test (5% significance) were used to test the effect of canopy height, trichome and cristalliferous idioblasts densities on the number of mines produced by T....
