Abstract  Background  Mass spectrometry-guided venom peptide profiling is a powerful tool to explore novel substances from venomous animals in a highly sensitive manner. In this study, this peptide profiling approach is successfully applied to explore the venom peptides of a Japanese solitary carpenter bee, Xylocopa appendiculata (Hymenoptera: Apoidea: Apidae: Anthophila: Xylocopinae: Xylocopini). Although interesting biological effects of the crude venom of carpenter bees have been reported, the structure and biological function of the venom peptides have not been elucidated yet.  Methods  The venom peptide profiling of the crude venom of X. appendiculata was performed by matrix-assisted laser desorption/ionization-time of flight mass spectroscopy. The...

A gynandromorph of Xylocopa nigrocincta Smith (Hymenoptera: Apidae)
Provedor de dados: 82
Autores: Lucia,Mariano; Abrahamovich,Alberto H; Alvarez,Leopoldo J.
We describe a mixed gynandromorph of Xylocopa (Neoxylocopa) nigrocincta from a single specimen from Argentina. The specimen presents bilateral asymmetry, with the right half of its head displaying male characters and the left half displaying female characters; the mesosoma presents male characters mostly in the right half of the prothorax, pronotal lobe and distal half of the fore tibia and in the pubescence of tarsus; the rest of the mesosoma and the metasoma display female features

NEW CASES OF GYNANDROMORPHISM IN XYLOCOPA LATREILLE, 1802 (HYMENOPTERA: APIDAE)
Provedor de dados: 84
Autores: ZAMA,PAULA CAETANO; COELHO,IGOR RISMO.
ABSTRACT Gynandromorphism is the most common case of sexual anomaly reported in bees and is characterized by individuals that show male and female traits simultaneously in the body. Gynandromorphic cases have been reported for 140 species of bees, an underestimated number comparing to the twenty thousand bee species described nowadays. Here we describe and illustrate the first case of a gynandromorphic Xylocopa darwini Cockerell, 1926 and the fourth case of Xylocopa varipuncta Patton, 1879. The specimens show a mixed form of gynandromorphism with predominantly female features and with all its male traits concentrated in one side of the body, right side in X. darwini and left side in X. varipuncta. The gynanders of X. darwini and X. varipuncta were...

Two new records of Gynandromorphs in Xylocopa (Hymenoptera, Apidae s.l.)
Provedor de dados: 84
Autores: Almeida,Rony Peterson Santos; Leite,Luis Anderson Ribeiro; Ramos,Kelli dos Santos.
Abstract Two new records of gynandromorphs in Xylocopa Latreille, 1802 (Hymenoptera, Apidae). Gynandromorphs are deviant morphological individuals with genetically distinct male and female tissues. Records of sex anomalies seems to be important to better understand the mechanisms regulating phenotypic expression. Herein, two new cases of gynandromorphs in carpenter bee species of Xylocopa from Brazil are described and figured: a mixed gynandromorph of the X. (Neoxylocopa) brasilianorum (Linnaeus, 1767) from São Paulo and a bilateral gynandromorph of the X. (Neoxylocopa) ordinaria Smith, 1874 from Sergipe.
