 Attacks of a Leaf-Miner (Phyllocnistis citrella'. 



At certain times of the year in nortliern India practically all new growth on young trees is 

 affected by this insect. (Original.) 



Fig. 2.— Cloth Cages Placed Over Young Citrus to Protect them from 

 the Ravages of this Leaf-Miner. 



The destruction of young foliage on trees as soon as it appeared necessitated artificial 

 manipulation in order to avoid the leaf-miner (Phyllocnistis citrella). Two cloth cages 

 were constructed, and in these were placed potted plants. After several hand pickings 

 the plants were freed of the leaf-miners, and the cloth protection permitted the voung 

 foliage to develop. (Original.)
