Longmont territory over an area of 161,280 acres and in the Sterling 
territory, which is in the northeast corner of the state on the South 
Platte River. This latter territory covers an area of 38,400 acres. It 
is hoped that when the results of this study are worked up some valu¬

THE PINK BOLLWORM (GELECHIA GOSSYPIELLA) IN 
EGYPT

Agriculture for the West Indies

Native Home and Distribution 
The pink bollworm appears to be a native of India and the southern 
Asiatic region. It was introduced into Egypt in badly ginned cotton 
lint. The importation of cotton from India into Egypt occurred be¬ 
tween the years 1903 and 1913. The following table shows the amount 
of cotton so imported:—

It was found in 1913 that a very considerable number of cotton seeds 
occurred in this cotton and that in these seeds considerable numbers of 
pink bollworms were found. 
Since that time cotton seed from Egypt has been imported into 
Brazil and Mexico and as a result pink bollworm is now established in 
those countries. 
At the present time the pink bollworm is known to occur in: Asia— 
India, Ceylon, Burmah, Straits Settlements, The Pacific Islands—The 
Philippines and Hawaiian Islands. Africa—Egypt, Sudan, East and 
West Africa, Nigeria and Zanzibar. In the Western Hemisphere the 
pink bollworm now occurs in Mexico and Brazil where it has recently 
become established as a result of the introduction of Egyptian cotton 
seed for planting. 
Food Plants 
In Egypt the pink bollworm is known to attack cotton of all varieties, 
teel or Indian hemp (Hibiscus cannabinus), bahmia or okra (Hibiscus
