 fmterculus, Wied. [The Fruit Fly, A. fraterculus, Wied.] — Anales 

 Soc. Rural Argentina, Buenos Aires, lii, no. 5, May 1918, 

 pp. 273-276, 1 plate. [Received 23rd September 1918.] 



Information is given on the history of the nomenclature of Anastrepha 

 fraterculus, Wied., and on its distribution. The genus is essentially 

 an American one, more particularly tropical and sub-tropical, and 

 about twenty species are already known. A. fraterculus is foimd 

 in Mexico, the Antilles, Cuba, Colombia, Venezuela, Ecuador, Peru, 

 the Guianas, Brazil, Paraguay, Uruguay, Bolivia, and in Argentina 

 as far south as Buenos Aires. It is the species recorded in 1874 in 

 Argentina by Weyenburgh under the name of Anthomyia persicorum. 

 A description of the adult is followed by biological notes. The eggs are 

 laid on frnits, which are mined by the larvae and fall. The larvae 

 reach maturity in 12-15 days, drop to the ground and pupate at a 

 depth of f-5 of an inch beneath the surface. An infested fruit may 

 harbour half a dozen or more larvae. All cultivated and wild fruits 

 appear to be attacked, a circumstance which hampers remedial 

 measures. The district of Tucuman, Argentina, has just suffered 

 from an outbreak of this pest, one of the best measures against which 

 is a poison-spray prepared by diluting in 10 volumes of water 1 volume 

 of the following mixture : — Honey 40 parts, molasses 40 parts, sodium 

 arsenite 2 parts, and sterilised water 18 parts. As this spray may 

 destroy many beneficial insects it should not be used indiscriminately. 

 The destruction of infested fruit is very necessary. An appeal is 

 made to all who have the requisite facilities to investigate the 

 parasites of this fruit-fiy.

During the month of May the insectary handled 30,300 pupae of 

 the melon fly [Dacus cucurbitae], from which were bred 1,669 individuals 

 of Opius fletcheri. The parasites distributed were : — Opius humilis, 

 214 ; 0. fletcheri, 1,182 ; Diachasma tryoni, 531 ; D. fullawayi, 215 ;

During the month of May 15 bags of Chinese rice were fumigated 

 for an infestation of Paralipsa modesta, a package of rice from Manila 

 was fumigated for an infestation of weevils, and boxwood trees from 

 California were fumigated for an infestation of the boxwood Psyllid 

 [Psylla buxi].
