study of temperature in relation to the feeding activities of grasshoppers in order to 
apply baits at the right time of day. It was also considered desirable to make a 
close study of other meteorological factors which might influence the insects’ feed¬ 
ing habits. A number of uniform tests were arranged to be undertaken in 1923. 
The alarming increase of the Wheat-stem Sawfly in Manitoba, Saskatchewan, and 
Alberta, and its wide distribution elsewhere, were discussed, particular emphasis 
being placed upon the importance of the larval habit in not cutting the stems until 
they begin to dry; a habit which enables farmers to harvest their crops in comparative 
safety by cutting them before they are dead ripe. The apparent failure of parasites 
to follow the sawfly into the grain crops was also discussed. 
A rapid increase of Hessian-fly over certain sections of the spring wheat growing 
region indicated that a serious outbreak may occur in the near future and it was 
deemed advisable to make a close study of the insect’s habits in the more northern 
sections of its range. The influence of humidity in relation to development was 
thought to be of marked importance in accounting for sudden outbreaks after the 
long periods of inactivity. 
It was arranged to hold the next meeting at Bozeman, Montana. Mr. Criddle 
was reelected chairman and Prof. R. A. Cooley was chosen as secretary for that 
meeting.

Horticultural Inspection Notes 
In the course of ship inspection, Mr. Max Kisliuk, Jr., an inspector of the Federal 
Horticultural Board, located in Philadelphia, discovered a specimen of Vriesia, in 
the nurses’ quarters of the United States Hospital Ship Mercy arriving from Guanta¬ 
namo, Cuba, to be infested with an interesting and apparently undescribed specise 
of Thrips, apparently closely related to Liothrips. Incidentally, the plant was aleo 
infested with mealy bugs, Diaspine scale insects, ants, etc., and some of the leavss 
exhibited diseased spots. 
Mr. Lee A. Strong, Chief of the Bureau of Plant Quarantine of California, reports 
that the Quarantine Inspectors of California have recently discovered that private 
railway cars entering that state frequently carry fruits prohibited by existing state 
quarantines. A recent inspection of some nine private cars resulted in the finding 
of fruits prohibited entry. 
Mr. J. T. Rogers, an inspector of the Federal Horticultural Board stationed in 
Washington, has been temporarily transferred to New York to assist in the enforce¬ 
ment of the Plant Quarantine Act. On July 1, Mr. Rogers will be stationed at 
Charleston, South Carolina for the purpose of assisting the Customs Officials at that 
port in the enforcement of the Plant Quarantine Act. 
Mr. Ivan Shiller, who during the past year has been stationed at Del. Rio, Texas, 
has been permanently transferred to New York City to assist in the inspection of 
plants and plant product imported under permit. 
The Arizona State Commission of Agriculture and Horticulture has recently 
erected at Yuma a vacuum fumigation plant to be used in the fumigation of citrus 
plants arriving in that state from California. Some four carloads of such stock were 
fumigated at the plant in question from March 26 to 31 inclusive. The plants were
