Dysmicoccus brevipes (Cockerell, 1893) (Hemiptera: Pseudococcidae) is one of the most frequent and abundant mealybugs in Brazilian vineyards, where it causes direct and indirect damage to the vines. In this study, we investigated the effect of plant structures, cultivars, and vine rootstocks on the development, survival, and reproduction of D. brevipes under laboratory conditions. Leaves of the tablegrape cultivar ÔIta´liaÕ (Vitis vinifera) and ÔNia´gara RosadaÕ (Vitis labrusca) and the vine roots of the rootstocks Paulsen 1103 (Vitis berlandieriV. rupestris) and IAC 572 (Vitis caribaea101-14 Mgt) were used as host plants. D. brevipes developed on different vegetative structures, cultivars, and vine rootstocks. D. brevipes showed the shortest developmental period and highest survival and fecundity rates on leaves of cultivar Ita´lia. Survival on leaves was signiÞcantly higher than on roots. Roots of IAC 572 were unsuitable for D. brevipes development, resulting in nonreproductive females.ThemealybugsÕ longevityonleaves and vine roots was similar. Higher intrinsic and Þnite rates of increase and net reproductive rate were observed whenmealybugs developed on Ita´lia leaves.Weconcluded that the host plant affects the development and survival of D. brevipes and that the choice of the most appropriate cultivar or vine rootstock can help to reduce pest infestation, and is therefore an additional component to be included in the integrated pest management of grapes. |

Many diseases and related degenerative processes including heart, câncer and Parkinson diseases are associated with rcactive oxygen species (ROS). In an effort Io preveni diseases, search for com-pounds with antioxidant activity hás been a major interestof dif-ferent research groups in natural products research. The objective of this research was to investigatethe antioxidant activity of EtOH leaf extract ofjacarando decurrrens and its fractions using the 2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH) assay [lJ, that uses s pé ciro me t ric method to determine radical scavenging activity, Rutinattheconcçntrationof l.Omg-L was used as the standard. Our results ha vê shown lhat crude extract and fractions had anti-oxidant activities mainly if tested at concentrations of 5.0 to 10.0mg-L. such activities, however. were lesser or equal to the standard (Table 1). The triterpenes, ursolic and oleanohc acids, were detected in the crude extract, Jd-1 and Jd-2, Possibly, these triterpenes are the active constituents responsible for the antioxi-dant activity |2j. At lower concentrations (0,6mg-L than the standard. Jd-3 fraction was the most active. The presenceof flavo-noids and glycosilated compounds were detected in jcl-3 fraction (2], This is the first attempt to demonstrate antioxidant activities found i n Já cara n (ia decurrens leaf extracts.
