8b THE LYC1IKK AND LUN(JAN 



posluitlanus. In its immunity to the Mediterranean fruit rly Mr. 

 Higgins classifies the lychee with the banana and pineapple. 



In addition to insect enemies bats often attack the trees when 

 the fruit is about ripe. In China these are driven off by means of 

 gongs sounded in the trees during the early hours of the evening or 

 by means of nets erected about the trees (tig. 21 ). 



Fungi 



Minor, superficial fungi can be found on the leaves of 

 lychee and lungan but in general the thick, tough, glossy nature of 

 the leaves makes their 'susceptibility to fungi very slight indeed. 

 Mr. Otto A. Reinking ' reports undetermined leaf spots and says. 

 ' The lychee tree is remarkably free from all injurious fungus attacks. 

 The tree apparently is very healthy, with waxy, resistant leaves and 

 a healthy bark. A black superficial leaf mold caused by a fungus of 

 the Mcliola or Capnodium type is present, but never in a serious 

 form. Minute black specks of a fungus of the Micropeltis form 

 may also be observed. " 



Lichens and Algae 



Lichens are very common on the trunks of lychee trees (tig. 

 43). There are a number of undetermined species of both lichens 

 and algae appearing on the trunk, branches and even the leaves of 

 these trees.
