Defence of nest by the female ofXylocopa fenestrata Fab. (Xylocopinae, Hymenoptera)

Summary

The female ofXylocopa fenestrata provides protection for her younglings by three ways: (i) regulation of nest size and leaving more than half the length of an internode of a bamboo vacant between the entrance and the last partition, (ii) by applying a repellent at the entrance of her nest, and (iii) by attacking the intruder with her strong mandibles, stinging it and ultimately ejecting a watery repugnant fluid. She resorts to the last method of attack only if annoyance continues for a longtime.

The authors are thankful to Dr.A. S. Atwal, Professor of Zoology-Entomology (now, Dean, College of Agriculture) for facilities and criticism of the results and to Dr.G. E. Bohart, United States Department of Agriculture, Utah State University, Logan, for carefully going through the manuscript and making valuable suggestions. They are also thankful to Mr.Surendra Kumar for varied assistance.

Résumé

Les femelles deX. fenestrata possèdent trois moyens de protection de leur progéniture:
  1. 1

    Régulation de la taille du nid, qui permet d'avoir toujours plus que la moitié de la longueur d'un espace entre nœuds de la tige de bambou, vide entre l'entrée et la dernière cloison.

     
  2. 2

    Application d'un répulsif à l'entrée du nid.

     
  3. 3

    Attaque de l'intrus en le mordant avec les fortes mandibules ou en le piquant, ou encore en éjectant un liquide répugnant.

     

Ce dernier mode d'attaque n'apparaît que si l'intrus persiste longtemps dans ses tentatives.
