The knowledge about population fluctuation of fruit flies (Diptera: Tephritidae) is an important tool to be adopted in pest control. Thus, this research aimed to analyse the population fluctuation of adults of fruit flies and the infestation of larvae in fruits depending on the conventional and organic agricultural systems of guava production in the 2010/2011 harvest. For monitoring the adults of fruit flies, five yellow sticky traps were installed in each system. The infestation percentage and the calculation of the ratio number of larvae/number of fruits were determined at harvest by harvesting 10 mature fruits/plant, in ten plants, for each system. In organic system predominated Anastrepha spp., principally in the period when the fruits were ripening or ripe, represented by elevated infestation percentage, while the conventional system presented low population density of fruit flies, with reduced larvae infestation inside the fruits.

In this paper, we analyzed situations where (a) one vocabular structure showed in two different ways in the same text or (b) had erasures. These structures fluctuations were extracted from texts written by children that, when the registers were done, were second graders of elementary school. Concerning the results, we verified: (1) that more than one prosodic constituent showed in the basis of fluctuation of vocabulary structures; and (2) that at least one of the limits of orthographic words was maintained in fluctuation structures. These results point to the recuperation done by writers with information they have access due to their insertion in (1) oral practices and (2) literacy practices.
