calcium polys ulphide is recommended when infestation is first noticed. 

 Badly infested canes should be burnt. Epiirix cucumeris, of which 

 potato leaves seem to be the preferred food, attacks the leaves of 

 chili plants. One part of Paris green or London purple mixed with 

 two parts of lime dusted on the leaves is suggested as a remedy.

 point of their emergence until they are able "to enter the fruit, when 

 they feed on the mesocarp. After about 4 to 8 days an exit hole is
