Barroetavena (F. a.) & Girola (C. D.). Segundo resumen de los 

 trabajos efectuados por la comisi6n nacional, designada por el 

 Ministerio de Agricultura para propagar la Prospaltella {Prospal- 

 tella berlesei, How.), como medio de destruir la Diaspis {Diaspis 

 pentagona, Targ.,), durante el segundo periodo, desde Abril a 

 Noviembre de 1915. [Second resume of the work done by the 

 National Commission nominated by the Ministry of Agriculture to 

 establish Prospaltella berlesei, as a means of destroying Aulacaspis 

 pentagona, during the second period of working, from April to 

 November 1915.] — Bol. Minist. Agric, Buenos Aires, xx, nos. 5-6, 

 May- June 1916, pp. 31-4-324, 1 col. plate. [Received 13th October 

 1916.] 



A report of the work done in 1914 has already been abstracted [see 

 this Revieiv, Ser. A, iv., p. 18]. From June to mid-October 1915, 

 929,776 twigs parasitised by Prospaltella berlesei were distributed to 

 2,523 fruit-growers in 245 localities in Argentina. No twigs were sent 

 to localities free from Aulacaspis pentagona and in doubtful cases a 

 careful inspection was made in order to avoid infesting immune areas. 

 The necessity for a further distribution depends on the conditions 

 observed before the next period June-October, 1916. In the opinion 

 of the Commi.ssion good results have been obtained up to the present 

 and instances are cited in support of this. On the twigs which were 

 distributed the following other insect enemies of A. pentagona were 

 noted : — RJiizobius lophantae, Blaisd., Coccidophilus citricola, Breth., 

 and Salpingogaster nigriventris. Big. Lahille has recorded the following 

 Aphelinine parasites of A. pentagona in Ai"gentina : — Aphelinus fusci- 

 pennis. How. ; Archenomus bicolor, How., Aspidiotiphagus citrinus, 

 Crwf., Tetrastichus canadensis, Ashm., Prospaltella martfeldti, How., 

 and Signiphora aspidioti, Ashm. Brethes has recorded : — Prospaltella 

 aurantii. How., Trichogrammatoidea signiphoroides, Breth., Diaspi- 

 dophilus pallidus, Breth., Prospaltoides Jiowardi, Breth., Signiphora 

 caridea, Breth., S. platensis, Breth., and Dimacrocerus platensis, Breth.
