Resumo: Somando-se ao suprimento nutricional, em especial a adubação nitrogenada, é imperativo o monitoramento rigoroso da condição residual do pasto. Objetivou-se avaliar a densidade e a estrutura do resíduo pós-pastejo em capim-massai adubado com N (0; 400; 800 e 1200 kg de N?ha-1?ano-1) e pastejado por ovinos num delineamento inteiramente casualizado com medidas repetidas no tempo. A elevação das doses de N influenciou as variáveis: densidade total de forragem residual, de forragem verde residual, de colmo verde residual, a relação lâmina foliar/colmo e o índice de qualidade da biomassa residual. Os ciclos de pastejo não exerceram alterações sobre a relação material vivo/material morto residual e densidade de forragem verde residual, sendo as demais variáveis modificadas pelos ciclos. A adubação nitrogenada proporciona respostas positivas sobre a densidade e estrutura do resíduo pós-pastejo do capim-massai. After grazing canopy structure and density of massai grass fertilized with nitrogen and grazed by sheep. Abstract: In addition to the nutrient supply, especially nitrogen, it is imperative to monitor carefully the residual condition of grass. To evaluate after grazing canopy structure and density of massai grass fertilized with nitrogen (0, 400, 800 and 1200 kg N?ha-1?year-1) and grazed by sheep in a completely randomized design with repeated measurements over time, this research was conducted. The nitrogen levels influenced the variables: residual total herbage density, residual green herbage density, residual green stem density, leaf/culm ratio and residual biomass quality index. The grazing cycles did not exert changes on the residual alive/senescent relation and residual green herbage density, being the others variables modified by the cycles. The nitrogen provides positive responses on after grazing canopy structure and density of massai grass.

The genome of Anticarsia gemmatalis multiple nucleopolyhedrovirus isolate 2D (AgMNPV-2D), which is the most extensively used virus pesticide in the world, was completely sequenced and shown to have 132 239 bp (G+C content 44.5 mol%) and to be capable of encoding 152 non-overlapping open reading frames (ORFs). Three ORFs were unique to AgMNPV-2D, one of which (ag31) had similarity to eukaryotic poly(ADP-ribose) polymerases. The lack of chiA and v-cath may explain some of the success and growth of the AgMNPV biological control programme, as it may explain the high recovery of polyhedra sequestered inside dead larvae in the field, which are collected and used for further application as biological pesticides in soybean fields. The genome organization was similar to that of the Choristoneura fumiferana defective MNPV (CfDefNPV). Most of the variation between the two genomes took place near highly repetitive regions, which were also closely associated with bro-coding regions. The separation of the NPVs into groups I and II was supported by: (i) a phenogram of the complete genomes of 28 baculovirus and Heliothis zea virus 1, (ii) the most parsimonious reconstruction of gene content along the phenograms and (iii) comparisons of genomic features. Moreover, these data also reinforced the notion that group I of the NPVs can be split further into the AgMNPV lineage (AgMNPV, CfDefNPV, Epiphyas postvittana NPV, Orgyia pseudotsugata MNPV and C. fumiferana MNPV), sharing eight defining genes, and the Autographa californica MNPV (AcMNPV) lineage (AcMNPV, Rachiplusia ou NPV and Bombyx mori NPV), sharing nine defining genes.
