can be easily collected in large numbers by the plucking-girls or children. 

 It is most important that the egg-masses be carefully collected during 

 the first half of the winter as the insect usually does great damage to 

 the tea bush in February to March. (2) The next important remedy 

 is plucking off all twisted leaves containing the caterpillars or pupae. 

 This must be undertaken at the commencement of an attack when 

 only a few shoots on each bush are involved. If an estate is badly 

 affected by this Tortrix throughout, so that there are almost no green 

 leaves or shoots, it is better to cut away all the twigs from near the 

 soil surface (of course the cut-off twigs should be soon destroyed by 

 fire) than to pluck the attacked leaves. This is rather a violent act, 

 but it is often practised by the natives in the districts where the tea 

 bushes are commonly injured by this insect, and this does little harm 

 to the tea-plant growth, its effect being rather a good thing. If the 

 badly affected tea bush is left naturally or only the twisted leaves are 

 plucked off by hand, the after-growth of the bush is rather poor and 

 there come no good crops. 



The a^pplication of light-traps is recommended by some entomolo- 

 gists as the moths are attracted by it. I cannot, however, recommend 

 it according to my good many experiences. My observations show 

 that the moths attracted by light are rather few, and consequently 

 that the expenses do not bring forth sufficient benefit. 



No. 20. — Adoxophyes fasciata, Wa,hm..^Archips minor, Shir. {Hirne- 



Hamaki.) 



This species was first brought to my notice in the year 1909, when 

 specimens of the insect were received from the district of Koroton in 

 Taichiu-Cho, with a report of serious damage to tea bushes. The out- 

 breaks are rather regular in that district, but annually the damage 

 done by this pest is not very serious throughout the tea districts. 

 When some tea gardens are badly infested by this Tortricid, these are 

 almost always followed by an attack of the preceding species. There 

 are many other plants affected by this caterpillar, of which egg-plants, 

 orange and mulberry are well known to us as the host-plants, but I 

 have never seen this insect on those plants in injurious numbers. When 

 the pest is -at its worst, the leaf is sometimes destroyed over a whole 

 garden, resulting in a serious loss of flush. 



The eggs are deposited by the female moth on the upper surface of 

 the leaf of a tea-plant, as in Homona menciana, but the egg-mass is usually 

 larger than the latter and consequently contains more eggs. The 

 caterpillar is rather cylindrical and is greenish : the head is flat, with 

 a pale yellowish orange tinge but it is rather greenish in the young
