Spraying was begun too late to be of much value end an extended drought now 
eliminates all possibility of control. 
Mr. Wolcott also reports that the present drought is responsible for 
the appearance of the cottony-cushion scale ( icerya purchasi Mask.) in 
noticeable abundance at various points in the previously Infested area, but 
none of the citrus growers coming to the laboratory for a supply of Rodolia 
cardinalis Muls. to release in their groves, report a heavy infestation* 
The scale has spread very little, not yet (April 10) having reached Vega 
Eaja in its westward dispersion. 
F. C. Bishopp reported on April lb that specimens of flies sent to 
the Bureau by H. L. Van Volkenberg, parasitologist of the Puerto Rico Agricul- 
tural Experiment Station at Mayaguez, have been identified as Cochliomyia_ 
americana Cushing and Patton. This is the species that has recently oc-used 
so much damage to livestock in the Southeastern States. ,7hile the fly is 
known to be present on other islands in the West Indies, this is the first 
authentic record of its occurrence in Puerto Rico. 
INSECT CONDITIONS IN HAWAII FOR MARCH 1^35

^otton bolls have just reached the stage for infestation by the pink 
bollworm ( Pectinophora gossypiella Saund.). Approximately 90 percent of 
the bolls are infested, the infestation ranging from one to seven larvae per 
boll. Parasitizction (by 7 species of parasites) is quite low. Cotton 
from Waianoe, Oahu, shows less than 0.5 percent parasitization and from Hono- 
lulu about 1 percent. 
Although fruits were scarce during March, the abundance of the Mediter- 
ranean fruit fly ( Ceratitis ccpitata Wied.) in citrus and mango orchards in- 
creased 50 percent over February. Parasitization at this season is very 
low — approximately 10 percent. 
Reports indicate that the melon fly ( Eactrocera cucurbita.p Coq.) is 
doing considerable damage to Chinese cucumbers. Growers are trapping and 
covering fruits for protection.
