THE MORE IMPORTANT RECORDS FOR MARCH 
Grasshopper hatching started in parts of Arizona in the latter half 
of February. In the Yuma district some of the nymphs had reached the third 
instar by the first week in March. In Nevada egg development was practical- 
ly complete by the end of March. 
Mormon crickets were hatching in the second and third weeks in March 
in Oregon. During the first week in March the coulee cricket was hatching 
in parts of Oregon. 
Cutworms were doing their usual early season damage as far northward 
as the Norfolk section of Virginia, and an outbreak of t’he army cutworm was 
developing in Mason Valley of Nevada. 
The sugar beet wireworm was seriously attacking carrots and lettuce in 
California. 
The green bug outbreak reported in the last number of the Bulletin has 
intensified in Oklahoma and Texas, and reports of heavy infestations have 
also been received from Mississippi and points in Virginia and Georgia. 
The chinch bug passed the winter with but normal mortality in Illinois, 
Kansas, and Oklahoma. In Kansas the population is reported to be the heav- 
iest thus far recorded in that State. 
In the eastern third of Kansas the hessian fly has done considerable 
damage and much more serious damage is anticipated. 
.At Clemson College, S. C., rather large numbers of egg masses of Com- 
stock’s mealybug survived the winter and the dormant spray operations. 
Plum curculio adults were observed in the Fort Valley section of Georgia 
by the middle of March and by the 19th, considerable numbers were appearing. 
Pear thrips began emerging in the Willamette Valley of Oregon the first 
of the month. 
Vegetable weevil was damaging garden crops and tobacco plant beds in 
Florida and garden crops in Mississippi. 
Mole crickets were damaging gardens in southeastern Mississippi. 
Considerable damage by the carrot rust fly was reported from several 
parts of western Oregon. 
The recently introduced weevil Sitona line at a L. is again attracting 
attention in the island counties of Washington State. This insect was first 
discovered, on Vancouver Island, British Columbia, in the spring of 1937- A 
single specimen of this weevil has also been found at Moscow, Idaho. It is 
a European pest which occurs in practically all the countries of Europe, in- 
cluding the British Isles, where on many occasions it seriously defoliates 
cultivated leguminous plants. In this country it attacks vetch, peas, and 
alfalfa, and in Europe it is recorded from practically all of the cultivated 
legumes and a few other plants.
