“…There are few studies on the biology and control methods for O. muricatus. The generation of information directed at differentiating males and females of this species is an important factor to support studies related to reproductive behavior and sex ratio, among others, as well as contribute significantly to the development of control methods for this pest (FERNANDES et al, 2005;CORDEIRO et al, 2011;FONSECA et al, 2014). VAURIE (1973), when describing the species O. muricatus, tried to correlate the size and shape of the spines of elytra with the sex of individuals, but dissection of the specimens revealed no such correlation, due to wear and tear of the spines during the life of the insect.…”

The weevil Ozopherus muricatus Pascoe, 1872 (Coleoptera: Curculionidae) is already considered a pest in Brazil for açaí palm (Euterpe oleracea Mart.) plantations. Its presence has become more frequent and caused significant reduction in the production of açaí fruit. Studies on the biology of this insect pest are still scarce, hindering its management. For studies on pheromones, for instance, it is essential to correctly identify the sex of the insect. The objective of this study was to evaluate the existence of sexual dimorphism in pupae and adults of O. muricatus in order to allow the identification of males and females. Larvae, pupae and adults were collected from açaí plantations and kept in biochemical oxygen demand (BOD) type incubation chambers. Adults and pupae were examined under a stereomicroscope, and dimorphism was determined through observation of external morphological characteristics. In addition, adults were dissected in order to observe genitalia and confirm the sex of specimens. In the pupae, sexual dimorphism was characterized by the presence of two protuberances in the terminal ventral region of the abdomen of females, which were absent in males. In adults, sexual dimorphism was also observed, based on the final abdominal segments. In males, it was possible to see all eight abdominal tergites, while in females tergite VIII is covered by tergite VII. Thus, the sexual dimorphism present in the morphological characteristics of O. muricatus allows the distinction between males and females of this species.

“…Devido à facilidade de medir o exoesqueleto dos insetos e por não apresentar distorções físicas como em animais de corpo mole, a morfometria se torna uma ferramenta vantajosa neste grupo (DALY, 1985). O uso de medidas de comprimento, largura, raio, área e recentemente da forma permitiu identificar instares (FONSECA et al, 2014), sexo e descrição de novas espécies. Além disso, a morfometria auxiliou na taxonomia e sistemática dos insetos (REIS, 1988), onde os caracteres contínuos são importantes para classificar e revelar a história evolutiva do grupo.…”

Crepuscular and/or nocturnal bees fly during the dusk, the dawn or part of the night.Due to the short time of foraging and sampling bias towards diurnal bees, nocturnal bees are rarely collected and poorly studied. So far, they have been mostly sampled with light and Malaise traps. However, synthetic chemical compounds resembling floral volatiles were recently found as a promise alternative to attract these bees. By reviewing available and collecting original data, we present information on nocturnal bees attracted and sampled with scent-baited traps. Bees were actively captured with entomological nets while approaching to the filter paper moistened with chemical compound or passively caught in bottles with scent baits left during the night. So far, all data available are from the Neotropics. Nocturnal bees belonging to three genera, i.e.Ptiloglossa, Megalopta and Megommation, were attracted by floral volatiles or caught in the traps with chemical compounds. They were attracted to at least 10 different
