ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS OF 



THE GLOBE 



A Braconid Feeding by Indirect Suction (Hym.). 



Many notes have been published during the last few years on the 

 feeding of parasitic Hymenoptera at the puncture hole made by the 

 ovipositor ; but B. Trouvelot, in the C. R. Soc. de Biologic, December 

 3, 1921, has published a note which brings in a new feature. The 

 American Braconid, Habrobracon johansenni Vier., has been sent over 

 to France by the Bureau of Entomology for the purpose of securing 1 

 its establishment there, since it is a parasite of the potato tuber moth. 

 It lays its egg in the larva of this moth after the latter has made its 

 cocoon, and this cocoon is naturally considerably larger than the larva ; 

 therefore, when the parasite lays its egg by thrusting its ovipositor 

 through the silken cocoon it is not able to feed at the puncture. 

 Trouvelot finds that when the Habrobracon, standing on the silken 

 cocoon, has thrust its ovipositor through the skin of the caterpillar it 

 secretes from the extremity of its abdomen a mucilaginous tube, which 

 hardens; then, after the ovipositor is withdrawn, the Braconid sucks 

 the juices of its host through this tube. 



My attention to this interesting communication was drawn by a note 

 which Doctor Feytaud has published in the Rci'uc dc Zooloyic Agricolc 

 et Appliquce (Bordeaux, January, 1922, p. 18). Doctor Feytaud adds 

 that J. L- IJchtenstein has noticed a similar procedure with Habrocytus 

 cionicida, a Chalcidid parasite of Clonus thapsi. 



A similar habit will surely be found among the parasitic Hymen- 

 optera in this! country, and the object in sending this note to Entomo- 

 logical Neil's is to ask its readers to watch for such cases.- L. O.

The Kiangsu Bureau of Entomology. 



The Bureau of Entomology, Kiangsu Province, National Southeastern 

 University, College of Agriculture, Nanking, China, has been organ- 

 ized with the following staff : Charles William Woodworth, Director 

 and Chief Entomologist; Goey Park Jung- and C. Francis Wu, Ento- 

 mologists; H. S. Chang, Entomologist and Curator; Huan-cjuang En, 

 Secretary and Editor ; Fo-ching Woo, Tsong-ling Tsou, Chi-yeu Wang, 

 We-i Young, Laboratory Assistants ; M. S. Chang, Pai-han Wang, 

 Clerks. 



The Bureau is fitting up a houseboat 48x11 as a floating laboratory for 

 its field investigations. It will provide living quarters for four Ento- 

 mologists and four sailors. The canals in this province will make it 

 possible to take this laboratory within easy walking distance of every 

 farm. There will be a motor boat to tow and tend the houseboat. 



The Bureau has undertaken the control of the flies and mosquitoes
