A geoestatística assim chamada devido a sua aplicação inicial nas áreas da geologia e mineralogia, hoje é aplicada em todas as ligadas ao estudo de variáveis regionalizadas. Na entomologia agrícola fundamentalmente no das dinâmicas populacionais insetos-praga benéficos, importância econômica. O conhecimento dinâmica populacional distribuição espacial populações são imprescindíveis para efetiva ...

To study the chemical constituents and the effect of petroleum ether extracts on P-gp in Vitro. Compounds were isolated by methods of phase silica gel column chromatography, gel column chromatography, preparation of thin layer chromatography and various chromatographic techniques, and identified by the physicochemical data of spectral analysis. We measured P-glycoprotein(P-gp) mediated ATP hydr...

UV-C irradiation is known to enhance plant resistance against insect pests. In the present study, we evaluated effects of low doses on Macrosiphum rosae infesting greenhouse rose (Rosa x hybrida) plants. The application 2.5-kJ/m2 leaves before infestation induced anti-herbivore and negatively affected aphid fecundity. No eggs first instar nymphs were recorded irradiated leaves, whereas an avera...
