 Union, Bangalore, iv, no. 2, 1922, pp. 69-75. 



A study of the lime-tree borer in the Bangalore district has shown one 

 generation only in a year. The adult beetles emerge from the pupal 

 chambers about the beginning of July and shortly afterwards eggs 

 are laid on the surface of small, tender twigs. These hatch within 

 a few days, and the larvae immediately begin to bore down the twig, 

 making small holes at some distance apart for the purpose of admitting 

 air and of emitting the powder3^ sawdust produced. The tunnels are 

 mostly straight, but are not continuous from the twigs and branches 

 right through the main stem ; sometimes, after boring down, the grub 

 tunnels transversely and then up the stem again, so that parallel 

 tunnels often communicate with each other. The greatest number 

 of tunnels found in a single stem of medium size was eleven. Different 

 stages of the borers can be found simultaneously in one tree. When 

 a grub in boring reaches the base of the stem it proceeds to tunnel 

 in the main root and the thicker rootlets, but does not make much 

 progress and frequently dies through lack of air and difficulty in 

 obtaining food. The larval stage continues from mid- July or early 

 August until the following May, when pupation generally begins. 



The amount of damage depends largely on the age of the plant and 

 the number of borers found in it. A well-grown tree can withstand 

 the attacks of many borers ; a young plant may die in about four 

 months. No parasites have as yet been found, though the fact that 

 the tunnel is left open behind the borer would facihtate the work of 

 parasitisation. 



For the destruction of the adults the leaves should be dusted with 

 lead arsenate, especially during July and August. Adults on the wing 

 should be caught with hand nets. Eggs can be destroyed when found 

 on the surface of twigs or the petioles of leaves. The most efficacious 

 practice, however, is to cut out young twigs as soon as they show 

 any sign of infestation and to burn them. The method of injecting 

 fluids, such as phenyle, kerosene or carbon bisulphide, into the tunnels 

 by means of a small syringe has been tried, but is not recommended 

 except as a last resource, as the grubs are very quick to turn away 

 from the poison and escape into some other tunnel, which their mode
