Antifeeding and Oviposition Deterrent Effect of spp. (Onagraceae) against (Lepidoptera: Plutellidae).

Plants produce a wide variety of bioactive compounds with insecticidal properties, such as secondary metabolites capable of interfering with the nutrition and reproduction of pest species such as . Thus, the objective of this study was to evaluate the effects of aqueous and ethanolic extracts of spp. (Onagraceae) on the feeding and oviposition of Choice bioassays were performed using aqueous and ethanolic extracts.

Bioecological and Behavioral Interaction between Pollinating Bees and the Pioneer Shrub in Degraded Area Suggests an Exotic Bee as Its Major Pollinator.

The flowers of plants of the genus are an important source of food for several species of bees. In the current study, we conducted an experiment with the aim to describe the reproductive biology and phenology of ; to identify the species of visiting bees; analyze the foraging behavior of bees; and to investigate whether the reproductive success of the species is related to the foraging activity of bees. We found that the flowers received visits from several native bee species (n = 7), in addition of the exotic honey bees which came to be the dominant species.

Phytochemical Screening and Bioactivity of spp. in the Control of (Lepidoptera: Plutellidae).

We tested the bioactivity of aqueous extracts of spp. (Myrtales: Onagraceae) on the biological cycle of . We assessed the duration of and viability during the larval, pupal and adult phases, as well as the influence of the extracts on the fecundity and hatching of eggs.

Visual evoked potential importance in the complex mechanism of amblyopia.

To compare the visual evoked potential (VEP) responses of amblyopic eyes with VEP responses of sound eyes in amblyopic children. A study of 65 amblyopic children with pattern-reversal VEPs elicited by checkerboard stimuli with large, medium and small checks. The children were classified into three groups: Group A, 22 children with anisometropic amblyopia; Group B, 16 children with exotropic strabismic amblyopia; and Group C, 27 children with esotropic strabismic amblyopia.

High prevalence of symptomatic acute HIV infection in an outpatient ward in southern Mozambique: identification and follow-up.

Objectives: To determine the prevalence of acute HIV infection (AHI) within the HIV-seronegative adult population presenting with reported fever in a district hospital in southern Mozambique and evaluate clinical, immunological and virological parameters of AHI.

Design: This is a prospective observational study.

Methods: Three hundred and forty-six adults presenting with reported fever at an outpatient ward at the Manhiça District Hospital in Mozambique were screened for AHI by HIV rapid serology testing, followed by HIV-RNA testing in HIV-seronegative individuals.
