Chromobacterium violaceum is a free-living Gram-negative bacterium found in soil and aquatic habittats; abundantly present in the Brazilian Amazon, it is an important example of exploitable microbial diversity of the tropics. In this study, 24 strains from the Brazilian Amazon…

Egg parasitoids have a short time frame in which their host eggs are suitable for parasitism, and in several systems these parasitoids respond to plant volatiles induced by oviposition on the plant (either in isolation or in combination with feeding…

European corn borer (ECB) [Ostrinia nubilalis (Hubner) ] (Lepidoptera: Crambidae) is known to infest Irish potato (Solanum tuberosum L.) but only causes economic damage during the first generation in East Coast potato producing areas. However, in Nebraska, second generation ECB…

This investigation compares the peritrophic membrane (PM) morphology along the midgut of susceptible (SL) and resistant (RL) Anticarsia gemmatalis larvae to the AgMNPV. The PM increased the thickness from the anterior to the posterior midgut region in both insects strain;…

Soy isoflavones are phenolic compounds comprised of aglucones, ß-glucosides and ß-glucosides conjugated with malonyl and acetyl groups. The ß-glucosidases are a heterogeneous group of enzymes which hydrolyse ß-glucosidic links of oligosaccharides and other glucosides conjugates releasing glucose. Thus the objective…

The object of this work was to verify the utility of a level IV fugacity model to simulate the environmental fate of the insecticide carbofuran when employed in the cultivation of irrigated rice. The model simulated the dynamic distribution of…

The present paper presents EIAR-Uruguay as an environmental management tool for indicating PPR?s participating farmers which practices and technology need improvements, and to facilitating the evaluation of the Project?s accomplishments. This experience has been recently brought to Chile in the…

Socio-environmental impact assessments were carried out on oleaginous crops for biodiesel production under the context of expanding demand in five regions of Brazil. The study brought together representatives of the main interest groups in Delphi-type workshops. Major impacts are related…

Technology impact assessment may be a helpful tool in the decision-making process. The present work suggests a method to evaluate the impact of technological innovation, providing information organized according to criteria and indicators in several areas where the innovation can…
