Genetic characterization of the peptidases of Polistes versicolor (Hymenoptera: Vespidae).
Starch gel electrophoresis with L-leucyl-beta-naphthylamide as substrate revealed five aminopeptidases in extracts of Polistes versicolor. These enzymes are presumably products of five structural gene loci. All but Lap1 aminopeptidases exhibited differential distribution in the developmental stages and in the tissues. Five dipeptidases were revealed with different dipeptides. These enzymes exhi...
متن کاملHymenoptera: Vespidae)
Workers in many insect societies interact via body contact with their nest mates, and social biting and other forms of contact may play a general role in regulating task performance. Here I present evidence that social biting affects task performance without direct reproductive conflict in Polybia occidentalis, a swarm-founding eusocial wasp. Polybia occidentalis workers engaged in social bitin...
متن کاملUltramorphology and Histology of the Ectal Mandibular Gland in Polistes versicolor (Olivier) (Hymenoptera: Vespidae)
The ectal mandibular gland (EMG) of wasps is homologous to the mandibular gland of ants and bees. This gland belongs to salivary system and its function stile unknown. The EMG of Polistes versicolor showed histological and ultramorphological features similar to that founded in ants and others wasps. This gland is constituted by a secretory region and a reservoir. The secretory region contains i...
متن کاملPrey captured and used in Polistes versicolor (Olivier) (Hymenoptera: Vespidae) nourishment.
The social wasps are predators of many insect species and the study of their preys can reveal the potential of these natural enemies in biological control programs. A total of 240h of collections of preys in 32 nests of Polistes versicolor (Olivier) was carried on in Juiz de Fora, Minas Gerais State, Brazil, from March 2000 to February 2001. The preys captured by P. versicolor were mainly those...
متن کاملFeed-forward and visual feedback control of head roll orientation in wasps (Polistes humilis, Vespidae, Hymenoptera).
Flying insects keep their visual system horizontally aligned, suggesting that gaze stabilization is a crucial first step in flight control. Unlike flies, hymenopteran insects such as bees and wasps do not have halteres that provide fast, feed-forward angular rate information to stabilize head orientation in the presence of body rotations. We tested whether hymenopteran insects use inertial (mec...
