RICS 
A PYRALIE MOTH (Chilo simplex Butler) 
Hawaiian R. H. Van Zwaluwenhurg (May 21): On March 1, 1928, the at- 
Islands tention of '.ir. D. T. Jul was called to the infestation 
of rice plants near Honolulu by larvae of a pyralid borer, 
since determined as Chil o simplex Butler. Between 1,500 and 
2,000 acres of rice are nz n to be infested, all con- 
fined to the Island of Oanu. The insect was first noted by 
Chinese growers in October, 1927, but they failed to bring it 
to the attention of any of the entomologists. Adults, larvae, 
and pupae were found during March, 1928, the oldest rice in 
any one district being the most heavily infested. Ey April, 
adults neve common among the plants in the field. The eggs 
are laid in small overlapping clusters either on the leaf 
blade or hidden between the leaf sheath and the main stalk. 
An idea of the severity of infestation of rice in some fields 
by April can be gotten from the record of between 4 and 50 
adult moths reared fro::; t'.vo stools brought in from a heavily 
infested paddy. Half-gro'-'.'n larvae in the insectnry attack 
sugarcane and corn readily, eventually causing the death of 
the young plants. Examinations of cane and grass lands imme- 
diately adjacent to heavily infected rice paddies have, to 
date, failed to show infestation by this species in sugarcane 
or r7ild grassas.
