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.
