flFALMJT HUSK FLY ( P.ha :-oletis ,iu landis Cress.) 
California Monthly Nev/s Letter, Office of Los Angelas County Agricultural 
Commissioner, Vol. 12, ho. 10 (October 15): That the walnut 
husk fly exists over a larger area in Southern California than 
it has heretofore been known to inhabit is indicated by the 
recent finding of larvae in walnuts growing at the mouth of 
Ca.jon Canyon. in San Bernardino County. Kii discovery made by . 
San Bernardino County, agricultural inspectors places the pest 
10 miles east of any previously known infestation. In addition 
the inspectors state that attacked nuts have aeon taken from 
isolated plantings of walnuts at points between the Chino-Pomona 
area, which has been known to be infested for. some time, ani the 
Cajon Pa.cs infestation — a condition which makes it ap-;ear likely 
that the fly is general throughout the area.

SOUTHERN GRELN STINK BUG ( Negar a viridula L.) 
Florida J. R. 7atson (October 20): The southern green stink bug is 
decidedly less abundant- than during October of the past several- 
years. This seems to be due to the great abundance oi the 
parasite Tricliopoca. The substitution of Crotalaria soectabilis 
for _C. striat a in many orange groves has also helped in this 
matter .
