from the same mango, the pupal stage cannot last long 

 The hybernation through the autumn and winter months evi- 

 dently takes place in the imago stage, though it has not been 

 discovered where the insects lie concealed through all these 

 months. But they are noticed in May, June and July flying 

 about. Whether these are the last season's weevils or fresh 

 weevils from early fruits, is not known. It is not known ex- 

 actly whether the oviposition takes place on flowers or young 

 fruits. No hole or pustule of any kind is noticed on thn sur- 

 face of affected fruits. 



1.268. The remedies suggested are : (i) Cultivation of 

 land under mango trees and growing turmeric, or ginger, or 

 some such aromatic plant that will grow well in shade. (2) 

 Letting poultry in after cultivation but before sowing of seed. 

 (3) Allowing servants and others habitually to cook under the 

 affected trees. (4) Carefully removing and destroying all stray 

 fruits, stones, rind and refuse of mango trees generally. 

 (5) Keeping crevices and holes in the trunk of the mango 

 trees plastered* over or otherwise obliterated. In Europe 

 trunks of valuable trees are painted or tarred, to protect 

 them from insect pests. It is possible the weevils hybernate 

 in the crevices of the trunk, and the effect of painting the 

 trunks on a large scale may be watched in some Eastern 

 Bengal* district. 



1.269. The larva of a dipterous insect (Dacus ferrugineus) 

 spoil late ripening mangoes in certain localities. The Malda 

 mangoes growing in the Katgola garden in Murshidabad are 

 annually spoilt by these maggots. The remedies recommend- 

 ed for this pest are the same as for the weevil. Probably the 

 oviposition in the case of the weevil takes place when the 

 trees are in full blossom, and in the case of the maggot, just 

 before the fruits ripen. Spraying of Kerosine emulsion or 

 asafcetida water, for the purpose of producing a stink in 

 the vicinity of trees one wishes to protect from the flies, is 



.the treatment indicated in the case of the maggot. The
