The silver leaf mite is recorded for the first time as a pest in 
Pennsylvania. 
The boll weevil has been disoovered on the Island of San Salvador 
since the last issue of this Bulletin. In North Carolina the new area 
invaded by this pest this year is already as wide as the entire area invaded 
last year and the migrating season is only half over. It has been found 
40 and 50 miles north of the limit of migration of last year in many places. 
The cotton worm is very severe in parts of Louisiana, completely de- 
foliating all the cotton in the vicinity of Alexandria and much from there 
to Opelousas, A late report has been received of heavy infestation about 
College Station, Texas. These outbreaks are so late, however, that they 
will probably have little effect upon the cotton crop. 
Wireworms of the genus Pheletes are estimated to be destroying potatoes 
valued at $250,000 in the Yakima Valley region of Washington, 
The imported cabbage worm and the cabbage looper are very seriously 
infesting cabbages in many of the middle Atlantic States. 
The sweet-potato white fly is doing serious damage to sweet potatoes 
and beans in Florida. 
The melon aphis has been extremely injurious to cantaloupes in the 
Imperial Valley of California. This .pest has also been very destructive in 
Nebraska, Indiana, and Maryland, and has appeared for the first time in 
many years as a serious pest in Ohio. 
One of the events of the month has been the very successful use of 
the aeroplane in distributing arsenicals in tall trees infested with leaf~ 
feeding insects. At Troy, Ohio, a 6-acre grove of catalpas over 30 feet 
tall was treated in 54 seconds, the application being thorough enough to 
destroy 99 per cent of the catalpa sphinx caterpillars infesting the grove.
