HIBISCUS INSECTS 
There have been heavy infestations of some hibiscus -hedges by the 
hibiscus whitefly ( Aleyrodes hibisci Kot.), causing considerable '• smutty 
appearance . The whiteflies were considerably parasitized by Encarsia sp. . 
Hibiscus hedges are -.-.ore and more becoming infested with Hemichior.as-pis 
minor Mask., which results in the death of the infested plants unless 
given prompt attention. 
GREE" SCALE 
The green scale ( Coccus viridis Green) often badly infests Ixora 
and some other ornamentals. Several parasites work on it but without any 
beneficial control. Two ladybeetles, Asya lutines !'ul*s. , and Cryptolaemus 
montrouzieri Muls., often fee', on the green scale quite abundantly. 
GARDEN LOOPER 
The garden looper (Plusia ; chalcites Esp.) is now well controlled 
in Honolulu by the parasite Litomastix floridana Ashm., first known to 
have become established here in February, 1929. 
RICE BORER 
Rice has yielded much better than any time since the rice borer 
( Chilo sim-olex Butl.) was first known here and caused such heavy losses 
in the spring crop of 1928. This has apparently been the result of the 
establishment of three parasites on the rice borer from the Orient; an e^g 
. . jparasite, Trichogramma .jaoonicum Ashm. . and two larval parasites, 
Amyo soma chilonis Vier. and Dioctcs chilonis Cush. 
COCONUT LEAF ROLLER . . •: 
Coconut leaves have been remarkably free from the" coconut leaf roller 
( Omiod es blackburni Butl.) this year, so they are mostly in perfect condi- 
tion as compared with the usual ragged appearance. This is undoubtedly due 
to several parasites, chiefly C_v_ hyneniac Vier. 
SUGARCANE LEAF ROLLER 
1 ere were only two or three slight outbreaks of the sugarcane leaf 
roller ( Qmiodes . accent a, Butl.) observed. Apparently the several introduced 
parasites have kept it well controlled.
