•465- 
orientalis Uaterh.) have been scarce this yeer and of no injury to the 
cane. However, in one plantation the grubs were found to have increased 
sufficiently to cause a significant reduction in cane at harvest time. 
Scolia manilao Astau., which controls this beetle in most of the infested 
area, had failed to do so here, but after the cane was harvested Scolia 
gained access to the field and in due tine had Anomala under control again, 
1TJSE BEETLE . 
The rose beetle ( Ado retus sinicus Burrri;) continues to be a general 
garden nest, on account of the extensive feeding of the beetles on the 
leaves of many kinds of ornamentals end garden plants. Scolia manila.e 
Ashm. parasitizes the grubs to some extent but not sufficiently. Attempts 
in the past several years to introduce additional parasites from the Orient 
for Adoretns have failed. 
sugarcane weevil borer 
The status of the sugarcane weevil borer ( Hhabdocnemis obscura 
Boisd. ) has remained about the same as for the past several years, it 
being satisfactorily controlled by the Few Guinea tachinid Ceromasia 
snhenonhori 7111. in the majority of the plantations. However, the 
borer still does considerable damage in some plantations, especially where 
mature cane stands for several months before being harvested,' and the 
borer is working in the canes that, are: covered by the accumulation of 
trash so the parasites do not have access to them. This damage is to be 
obviated by earlier harvesting of such fields. A recently introduced 
variety has been observed in several instances to be less attacked by 
borers than some other varieties growing with it. 
MANGO WEEVIL 
Examination of 50 mango seeds showed 80 per cent containing the' 
mango weevil ( Crypto rhynchus raangiferae Fab.). Their presence in the 
seeds had not impaired the mangoes for eating, but the seeds were snoiled 
for propagation purposes. 
SUGARCANE LEAEHOPFER 
The sugarcane leafhopper ( Ferkinsiella saccharicida 3: irk. ) has been 
satisfactorily controlled by its natural enemies almost entirely through- 
out the Islands. There was an outbreak on one plantation in which, in a 
field of about 100 acres, the leafhoppers increased to injurious numbers 
before being checked by their enemies. The most important enemy, 
Cyrtorhinus mundulus Breddin, soon increased sufficiently to check the 
outbreak, and in three months the leafhoppers had entirely disappeared 
without serious damage to the cane.
