THE MANGO WEEVIL. 
(Cryptorhynchus mangifere Fab. ) 
By C. L. Maruartt, 
Entomologist and Acting Chief in Absence of Chief. 
The prospective mango industry of Florida is jeopardized. The mango 
weevil is likely to be introduced in the seeds of the mango. Shipments 
of mango seeds now coming to this country are largely infested with 
this weevil. Introductions of any mango seed or fruit into mango- 
growing districts are attended with the gravest danger. The pre- 
cautions indicated in this circular should be strictly carried out. 
The most serious insect pest of the mango in oriental countries is the 
mango weevil (Cryptorhynchus mangifere Fab.) (fig. 1). This weevil

is related to the boll weevil and the chestnut weevil, and this, aside from 
its well-known destructive work on the mangoes, is suflicient indication 
of its undesirability. It is probably of Indian or at least of oriental 
origin, and has already obtained foothold in most of the important 
mango-growing countries, being carried readily with seed for plant- 
ing. It now inhabits all of the mango regions bordering on the Indian 
Ocean and adjacent islands, and occurs throughout the East Indies,
