The objective of this study performed in the Atlantic forest region of the South of Bahia (Brazil) was to examine the influence of the presence of the forage legume Desmodium ovalifolium in pastures of Brachiaria humidicola on the nitrogen recycled through plant litter over stocking rates of 2, 3 and 4 head ha-1. The results demonstrated that the presence of the D. ovalifolium in the pasture significantly increased the protein content of the associated Brachiaria grass, and the rate and quantity of N recycled through the litter pathway. While had no significant increase in animal weight gain due this legume, the increase in N recycled through the litter pathway should provide an increase in the sustainability of pasture production, especially at the lower stocking rate where the grazing pressure was lower and the proportion of legume was higher. |

Surveys on Coccinellidae (Coleoptera) in Sete Lagoas city, Minas Gerais state, Brazil, indicated the parasitism of adults of the species Coleomegilla maculata De Geer, 1775, Eriopis connexa (Germar, 1824) and Olla v-nigrum (Mulsant, 1866), by Dinocampus coccinellae (Schrank, 1802) (Hymenoptera; Braconidae: Euphorinae). Since then, the parasitoid have been maintained in its original hosts at the Insect Rearing Laboratory - LACRI of the Brazilian Agricultural Research Institution - Embrapa Milho e Sorgo. Besides the citation of occurrence in Brazil, this work also indicates the parasitoid preference for C. maculata (70% of parasitism), followed by O. v-nigrum (43.3% of parasitism) and E. connexa (36.7% of parasitism). Total life cycle of D. coccinellae was longer on C. maculata (32.4 ± 0.48 days), compared to O. v-nigrum (29.5 ± 0.49 days) and E. connexa (27.8 ± 0.4 days). Due to the relatively high percentage of field parasitism, D. coccinellae can reduce the efficiency of biological pest control by Coccinellidae predators especially in the case of C. maculata. |
