Abstract Laboratory and greenhouse studies were conducted with the Neotropical brown stink bug, Euschistus heros (F.), to evaluate and compare adult damage at two infestation levels (2 and 4 adults/plant) and feeding behavior on seeds of three resistant soybean cultivars bearing the Block technology (?BRS 1003 IPRO?, ?BRS 543 RR?, and ?BRS 391?) compared to a susceptible cultivar (?BRS 5601 RR?). No difference in number or weight of damaged seeds (as percentages) was found among the cultivars at either infestation level. Differences were only observed between infestation levels within cultivar; higher values were reported with 4 adults/plant, except for ?BRS 543 RR?. At 2 adults/plant, total seed area damaged (mm2) and percentage of seed area damaged were signifcantly lower only on ?BRS 1003 IPRO?; signifcant differences among cultivars were found in damage to internal but not external seed surfaces. At 4 adults/plant, all Block cultivars differed from ?BRS 5601 RR? in overall seed damage, and greater percent damage occurred on both seed surfaces on ?BRS 5601 RR?. Electropenetrography (EPG) demonstrated that adults reached and fed in the seeds of all soybean cultivars. However, the feeding event duration in seeds of Block cultivars was much shorter than on ?BRS 5601 RR?, which likely explains differences between internal and external seed damage. Furthermore, the total duration of feeding activities on seeds of Block cultivars was ca. 4?6 times shorter than on the susceptible cultivar; these two EPG feeding variables account for the lower seed damage observed for the Block cultivars. These cultivars represent an important new strategy for pest control on soybean.

Milk production in Brazil is largely based on pasture utilization which represents an in expensive feed compared to processed or conserved forages. Brachiaria brizantha and B. decumbens are prevalent in Brazil owing to their high yield potential and good adaptation to acid and infertile soils. Their forage quality is, however, considered low in view of the nutritional needs of animals of high genetic potential for milk production. Fortunately, there is intra and interspecific variation for forage quality in Brachiaria germplasm to be exploited in the development of new cultivars. This paper reports on the evaluation of 47 interspecific hybrids between B. ruziziensis (R) × B. brizantha (B) and R × B. decumbens (D), with the objective of selecting potential new cultivars that combine high yield and forage quality. The experiment was arranged in a completely randomized design with two replicates and two common cultivars as controls. Data of the total dry matter yield, dry matter percentage, plant height and regrowth vigour of six cuts were collected. Samples from the third cut were analysed for nutritive value using near infrared spectroscopy. Results confirmed the existence of variability for the majority of the traits analysed so high quality and productive hybrids can be selected. |
