“…In addition, the setting temperature may have been of great influence on the further development of these insects, because according to Caneppele et al (2010), the optimum temperature for S. zeamais development is between 28 °C, although its development also occurs between 15 and 34 ° C, thus being consistent with the temperature values of the study settings, which range from 24.6 to 27.6 ° C from the first to the last evaluation period. Another way to explain that natural insecticides have not presented efficiency may be related to the method of extracts extraction, thus agreeing with Tavares and Vendramim (2005), which have also found no insecticidal effect of aqueous vegetal extracts in relation to S. zeamais adults. According to Tavares (2006), compounds with insecticidal activity present in some plants cannot be extracted in high polarity solvents, which 293 Chemical pesticides… VILARINHO, M. K. C. et al…”
