O presente trabalho teve como objetivo comparar a eficiencia do extrator Mehlich 3 com os demais extratores normalmente utilizados na determinacao de nutrientes. Os extratores utilizados foram KCl para determinacao de (Ca e Mg), Mehlich 1 (K, Na e P), e para a determinacao dos micronutrientes (Cu, Zn, Fe e Mn) foram utilizados os extratores DTPA, HCl e Mehlich 1. Foi observada a existencia de correlacao entre os resultados obtidos, utilizando-se o extrator Mehlich-3 e os demais, demonstrando a possibilidade de utilizacao deste na analise de macro e micronutrientes. |

No impact of Bt soybean that express Cry1Ac protein on biological traits of Euschistus heros (Hemiptera, Pentatomidae) and its egg parasitoid Telenomus podisi (Hymenoptera, Platygastridae). Biological traits of the stink bug Euschistus heros and its main biological control agent Telenomus podisi were evaluated under controlled environmental conditions (25 ± 2°C; 60 ± 10% RH; and 14/10 h photoperiod) by placing first instar nymphs into Petri dishes with pods originating from two soybean isolines (Bt-soybean MON 87701 × MON 89788, which expresses the Cry1Ac protein, and its near non-Bt isoline A5547) where they remained until the adult stage. Due to gregarious behavior exhibited by first instar nymphs, they were individualized only when at the second instar. Adults were separated by sex and weighed, and pronotum width of each individual was subsequently measured. They were placed into plastic boxes containing soybean grains of the same soybean isoline as food source. Egg viability and female fecundity were assessed in adult individuals. Adult females of T. podisi (up to 24h old) were placed with eggs of E. heros from mothers reared on both soybean isolines. Nymphal development time, insect weight, pronotum width, sex ratio, female fecundity, and egg viability (% emergence) of Euschistus heros did not differ between treatments. Eggto-adult development time, female longevity, sex ratio, and percentage of parasitized eggs were not impacted by the Bt-soybean (expressing Cry1Ac protein). Results indicate that the Bt-soybean, MON 87701 × MON 89788, has no direct significant impact on the two studied species.
