INSECTS INJURIOUS TO AGRICULTURE IN JAPAN 



77 



spersa, Adoxophyes privatana, Biston mmHjinata, Clania variegata, 

 Gracllarla theacvora, Homona menciana, and Chlorlta flavescens 

 though about 50 species are recorded as attacking the plant, of which 

 15 may be considered as of major importance. Though tea is also 

 an important crop in Japan, most of the information regarding the 

 insects which attack it is presented in publications from Taiwan. 



The damage to tea by various insect pests consists not only in 

 direct physical injury to the plant, but also in a damaging of the 

 quality of the young foliage which is plucked for manufacture into 

 the tea of commerce. With certain of the pests, considerable damage 

 may be done even though the insects are relatively few. The suck- 

 ing insects in general are of more consequence than upon other 

 plants, owing to the fungus growth which develops in the honeydew 

 and excrement deposited by many of them. A number of the 

 lepidopterous species inflict injury out of proportion to their numbers 

 by inclosing a shoot or even an entire branch in a silken web, and 

 the amount of foliage actually eaten may be very small compared 

 with that rendered unfit for use by the web.
