| Foi feito um levantamento da população de artrópodes num agroecossistema de batata, Solanum tuberosum L., em Santa Maria, RS, durante o ano agrícola 1989/90. O objetivo desta pesquisa foi comparar a entomofauna em diferentes cultivares de batata durante a época tradicional do seu crescimento e na safrinha. O experimento consistiu de nove cultivares durante a época tradicional, e de dez cultivares durante a safrinha. Amostras de insetos foram coletadas semanalmente com a rede de varredura (15 redadas por amostra). Os coleópteros foram predominantes durante a época tradicional do crescimento da cultura, e os dípteros, na safrinha. As espécies fitófagas mais freqüentes foram: Epitrix sp., na época tradicional, e Diabrotica speciosa (Germar), na safrinha,... |

| ABSTRACT The aim of this study was to evaluate the residual effect of pesticides sprayed on peach orchards on S. zeamais. The study consisted of two experiments, according to the method of pesticide application. For Experiment I, pesticides were directly sprayed on peach trees and in Experiment II, the application of pesticides was performed under laboratory conditions. In both Experiments, the effect of pesticides was assessed in laboratory through the release of ten weevils per peach fruit. The effect of treatments was assessed by variable number of surviving insects. The results for pesticides [a.i. (ml or g.100L)] have shown that application of treatments in the field (Experiment I), malathion (200) presented persistence at 1DAT (Days after treatments... |
