This article aims to present a list of the main influences experimented by architects and urbanists to formulate an urban thought of Sao Paulo City. This way, it will be discussed the main issues raised between the first decades of the XX Century until the 1950s, trying to foresee how the engineers and architects worked to incorporate the urbanistic proposals from Europe and the United States. On the first three sections of this article, it will be presented the concepts that effectively impacted the paulista urban thought of the first half of the XX Century: Sanitarism, the pendulum design: between the Mesologic Theory and the Microbian Theory; Camillo Sitte's historicist formulation; Howard Garden Town and the French experience. Our analysis was formulated by having as a reference a broad and systematic literature, documents stored at Arquivo Histórico Municipal de Araraquara (SP), visits to Faculdade de Arquitetura e Urbanismo da USP Library and to Faculdade de Ciências e Letras da Unesp, Araraquara. The analysis shows that two urbanistic planner streams that happened in São Paulo State were clearly influenced by the conceptions that led the urbanistic debates in the first half of the XX Century. So, these conceptions compose a painting of the urban interventions in São Paulo City.

Insecticide potential and efficaciousness of vegetal extracts concentrations from six botanic families in three different modes were analyzed on the nymphs of the silverleaf whitefly Bemisia tabaci (Genn. 1889) on a tomato plantation Lycopersicon esculentum Mill. Nymph breeding was kept in cherry tomato shrubs. Test solutions were obtained from successive extractions with ethanol and evaporation in a rotary evaporator. Tests consisted of 10 solutions in four concentrations (500; 1,000; 1,500 and 3,000 μg/mL) and control treatment (distilled water + 1% DMSO) under three different modes of activity, namely, contact, translaminar and systemic. Experimental design was totally randomized with four repetitions and eleven treatments. Means were compared by Scott-Knott test at 5% probability and lethal concentrations (CL50) were calculated by POLO. In the case of contact activity mode, all extracts had efficiency above 50% with the highest concentration (3,000 μg/mL) in which the highest efficiency for all extracts tested was verified. There was a need for dose increase in translaminar activity mode for similar results, whereas in the case of systemic activity the best performance was obtained with extracts of Nerium oleander, Derris amazonica and Ipomoea carnea. Extracts of the last two caused a higher percentage when compared with that of other extracts in all activity modes lower than CL50.
