Mr. Higgins adds, 'Later examination disclosed results so 

 much more favorable to the nicutin sulphate and fish-oil soap that the 

 other treatments were abandoned. This spray was applied again on 

 March 28 (the first on February 11), April 11 and 25. One tree 

 received treatment on March 11. By the end of April the mites 

 were practically eradicated/' 



-1 Lij<'ln< 1 1'< < Borer 



Another very common insect attacking the lychee is a tree 

 borer. Its work is very manifest on both lychee and lungan by the 

 debris left upon the bark of the trees (fig. 4.-?). Mr. C. W. Howard 

 of the Canton Christian College is working with this insect, which he 

 has not yet identified. The Chinese are constant in their warfare 

 against this borer by piercing it with wire thrust into the channels 

 which it bores in the trunk of the tree; or by making "hisser" 

 firecrackers which are spurted into the holes, thereby burning or 

 suffocating the insect in its larva stage (fig. 47). Some times the 

 holes are plugged with tallow which is also said to be very effective 

 in smothering the life out of the larvae. 



Molh Larva At fuelling Flou't-r N/fw.s and Fruit 



In the vicinity of Canton the larva of some insect quite com- 

 monly attacks the flower stems of the lychee. Larvae are also some- 

 times found in the fruit. But whether or not the two are of the same 

 species has not as yet been determined. Mr. Higgins * also reports 

 a lychee fruit worm at work in Hawaii, * the larva of a tertricid moth 

 (Cryptophlebia illepida)." The relationship of these insects 

 cannot be known until these at work about Canton are. identified. 



X <<;!< I nsf-cts and OUnr Enemies 



Some scale insects also attack the lychee and lungan but the 

 infection has never been noted as very serious. 



Mr. Higgins ' reports from Hawaii a root inhabiting mealy 

 bug, the hemispherical scale Saissetia hcmisphcrica, the Japanese 

 beetle Adorctus tenuinwrn[fttus and the larva of a moth Archips
