Plant Sanitation. 



is applicable to hedges of Duranta when attacked by the bug. The Lantana 

 bug is one of the most active of its family. It has proportionately larger legs 

 than any other Coceid with which I am acquainted. It is also extremely pro- 

 lific, a constant stream of larvae emerging from the long tubular ovisac which 

 gives the female insect such a peculiar appearance. 



Further complaints of depredations by hornets (Vespa cincta) have been 

 received from bee-cultivators in the Kurunegala district. My correspondent 

 writes that the hornets "hover over the entrance to the hive and carry away 

 the bees as they come out. They have already devastated twenty-two hives. I am 

 killing them by hundreds by using pieces of meat soaked in arsenic." The nests of the 

 hornets should be searched for and burnt. This is very easily done with a torch 

 made of straw or rags soaked in kerosene on a long pole. When held below 

 the nest the hornets fly into the flame and never think of attacking the person 

 at the other end. The nest also catches fire and smoulders slowly away. In 

 addition to this treatment, a small boy with a butterfly net might be stationed 

 at the hives, to catch and kill any hornets that may be hovering about.
