The Mexican fruit fly,"* known also as the Mexican orange maggot 
and Morelos fruit worm, is found in Mexico, where it is considered 
a serious pest of the mango, orange, sweet lime, guava, and a number 
of other plants. The adult measures nearly one-third of an inch in 
length and is of a dull ocherous yellow color, with the wings trans- 
parent, mottled, and striped with brownish-yellow bands. The eges 
of this species are deposited under the skin of ripening fruit. 
The West Indian fruit fly,* might be introduced into Florida and 
the other Gulf States, as it is at present in Mexico, Central America, 
‘South America, and the West Indies, where it infests the guava, 
coffee, pear, peach, mango, Para plum, Japanese plum, Japanese per- 
simmon, and a number of other fruits. In these countries it is con- 
sidered a very serious pest. The adult fly is about one-half inch in 
length, with a wing expanse slightly over 1 inch. The color of the 
body is rust yellow or brownish yellow. The wings are clear, tinted 
in part with a characteristic pattern of yellow brown. 
The mango hopper‘ is a mango pest which in certain parts of 
India is reported to reduce the mango crop to one-third its normal 
value. The adults are small, dark, wedge-shaped insects which jump 
when disturbed. They appear at the time the mango is in flower, the 
time at which the principal injury is done. The eggs are laid and 
hatch in the flower panicles, and the young as well as the adults 
blight the bloom by sucking the juices that should assist in the forma- 
tion of the fruit. 
The mango seed weevil ** is a serious enemy of the mango, especially 
in Hawaii, where it is reported to have infested from 60 to 90 per 
cent of the crop. There is danger of its introduction inside the seed. 
Tt is also present in the East Indies, the Philippines, the Straits Set- 
tlements, Madagascar, and South Africa. The adult weevil is from 
one-fourth to one-third inch in length. When it is nearly developed 
it is pale pinkish in color, later changing to a dark brown with yellow 
markings. The egg is deposited in the fleshy part of the fruit. When 
hatched the larva enters the seed, undergoes its entire development 
there, and emerges as an adult.
