NOTES FROM EGYPT, DECEMBER 23, 1935, 
by 
A. H. Rosenfeld 
A recent survey has revealed that Pyrausta nubilalis Hbn. is 
generally distributed' over Loner Egypt, extending as far south as Giza 
Province (near Cairo). Investigations lead to the conclusion that four 
generations occur annually in Egypt. Examination of individual infested 
cornstalks at Damietta and Alexandria revealed from 10 to 12 live larvae 
per stalk. In a number of cases Sesamia sp. and O hilo sp. were found 
feeding in the same internode with the corn "borer and at times their 
galleries were joined. In Alexandria complete infestations may he found and 
30-percent infestation is 'common. 
The degree of infestation by Polychrosis botrana Schiff . in the 
vineyards around Amria (Lower Egypt) last season averaged about 12 percent, 
whereas the maximum damage reached 30 percent. 
In a recent survey the long-winged form of mole cricket ( Gryllotalpa 
gryllotalpa L. ) was noted everywhere in small numbers, but the short -winged 
form (G. gryllotalpa cophta Haan) seems to be by far the most common and 
widely distributed type, especially in Lower Egypt (Alexandria, Port Said, 
Suez, and Ismailia). G. africana Bdv. was seen more particularly in the 
Eayum (Middle Egypt) and in some parts of Lower Egypt, such as Dessuk, 
Fareskur, and Mit Gamr. 
NOTES PROM PUERTO RICO 
P. M. Vandenberg, of the Mayaguez, P. R. , laboratory, reports that 
in the investigations of the insects affecting corn recently undertaken 
in Puerto Rico, the work of a dipterous maggot was observed in ears of green 
corn. This maggot has been identified as the young of a fly, Euxesta 
stigmatias Loew. A close l}' allied species in this country is well known 
as a scavenger. The Puerto Rican species, however, has been reared on 
fresh green corn from egg to adult. 
H. K. Plank sent in specimens of Cryptotermes cavifrons Bks. and 
C. brevis Walk, , which were taken on January 20 as they were flying 
around lamps in a house at Mayaguez, P. R. (Det. by T. E« Snyder.)
