SOME SOI I H INDIAN INSEl fS, ETC. 



LIST OF ALLIED PLAN IS. 



I'm-: following list, in the preparation of which I have received 

 considerable kind assistance from Rao Bahadur K. Rangachariyar, 

 Lecturing Botanist, shows the commoner plants and trees grouped 

 under their Natural Orders. In view of the fact that many 

 species of Insects are confined to closely allied plants, or at least 

 exhibit a preference for the plants contained in the limits of a 

 Natural Order, it is equally important for the Entomologist and the 

 Agriculturist to know which plants are likely to be attacked by 

 any particular insect, especially in view of control by rotation of 

 crops. For example, an insect which damages mustard is likely 

 to attack cabbage if the two crops are grown near one another in 

 spai e or time. Many insects are of course polvphagous (i.e., feed 

 on many different plants) but. as a rule, a careful consideration of 

 the relationships of the crops themselves will often avoid consider- 

 able loss by Insect Pests.
