The Insect and Related Pests of Egypt. Vol. i. The Insect and 
Related Pests Injurious to the Cotton Plant. Part i, The Pink 
Bollworm, by F. C. Willcocks. Sultanic Agric. Soc., quarto, 339 
pages, 17 text figures and 10 plates, 4 colored, 1916. 
This work deals with a very exhaustive investigation of the insect pest which is 
now attracting very great attention in most of the cotton producing countries of the 
world, and which threatens to become established in the United States. It is a most 
welcome publication on account of its timeliness and on account of the painstaking 
work upon which it is evidently based. It is most fortunate for the cotton producers 
of the world that it has been possible under the difficulties of the present time to pub¬ 
lish the work in such full and commendable form. 
The work covers all phases of the pink boll-worm problem in Egypt, including the 
history and origin of the infestation, the nature and amount of the losses, food plants, 
life history (in the broadest sense), natural enemies and means of control. 
The thoroughness of the work is indicated by the number of individual observations 
on points in the life history of the pest. In most cases scores or hundreds of observa¬ 
tions were made on such points as the duration of the stages. The form and amount 
of damage under various conditions is indicated by equally numerous observations. 
The author shows that the pink bollworm was introduced in Egypt about 1906, at 
which time there was a very great increase in the amount of Indian cotton imported 
into that country. There was a very high proportion of seed left in the Indian con¬ 
signments. The view is held that India is undoubtedly the original home of the pest. 
American entomologists will be especially interested in the author’s remarks re¬ 
garding the possibility of the adaptation of the pink bollworm to the conditions exist¬ 
ing in the United States. The following are his remarks on this subject: 
“If the pink bollworm once gained a footing in the Southern States it would stand 
a godd chance of becoming firmly established and might well prove to be as serious a 
pest to cotton as the notorious Mexican cottonboll weevil. 
“The climate being suitable for commercial cotton growing, there seems no particu¬ 
lar reason or reasons to doubt that it would not also be favorable to Gelechia gossy- 
piella. It is true that frosts occur in some parts of the cotton growing belt; but 
nothing approaching sufficient severity to seriously inconvenience this species would 
be experienced, since this insect appears to be particularly resistant or adaptable to 
both heat and cold.” 
A very careful analysis of the statistics of production of cotton in Egypt, together 
with records of studies in individual fields, leads the author to the conclusion that in 
1914 there was a loss of approximately one hundred pounds of seed cotton per acre. 
This is said to represent from 21 to 27 per cent of the crop.
