The larva of the mango weevil, Cryptorrhynchus mangiferae, F., feeds in the 

 stone, where it pupates. It is not a seriously destructive pest. 



Ceratitis catoiri, Guer. A certain amount of damage is caused by the larva 

 of this fruit-fly. 



Peaches. 



Adoretus versutus is more or less common all over the island, and frequently 

 attacks the leaves. 



Aulacaspis pentagona, Targ., occurs on the stems and twigs. In the hot coastal 

 regions this pest is the worst of those affecting this plant. It is extremely common 

 and causes the death of a great number of trees every year. 



Cvdia pomonella, L., is another regular pest and is most harmful to peaches. 

 On an average 75 per cent, of the fruits are infested, especially at the beginning of 

 the ripening season. 



Banana. 



Bananas are grown all over the island, and many varieties are cultivated, amongst 

 them being the " Nain " and " Oilier." The " Gingeli " is affected with a 

 disease of the fruit in the colder districts, but the other varieties thrive all over 

 the country and form one of the chief food-stuffs of the poorer classes. They con- 

 stitute the "'most popular fruit of the island, as they are cheap and procurable during 

 most of the year. 



The black banana, weevil. Cosmopolites sordidus, Germ., is the only pest. The 

 larvae live in the root-stock and occur sometimes in such great numbers as to cause 

 the death of the plant. The varieties known as " GingeU " and " Banane Carrie " 

 are particularly affected.
