reported adult "beetles as being active on the tree trunks at 
Fresno. T Ton~ were seen feeling. 
Weekly ITe-s Letter, State of California Department of Agriculture, 
Vo7 . 7, No. 8 (Acril 13): Unfortunately a serious elm pest, the 
European elm leaf -beetle has "become established in this State vriLth 
its center of infestation at Fresno. It -as first reported in 
June of last year. This beetle has born in the far eastern States 
.r.any years, but never nearer to California than northern Cre^n. 
J-ast ho'7 it -as carried to California is not knona. These beetles 
attack the elms, but as far as is no" kno*"n they do not destroy 
othir shade trees. 
The natural spread of these beetles is very rapid. They are 
active in flight and alight upon people, automobiles, and other 
objects. The fuIl-gro T ~n larvae or grubs crarl do"~n the tree 
trunks or fall from the trees. Eoth beetles and grubs al ighting 
on automobiles parked under elms may be c?rried long distances. 
By the end of the year light infes tat ions -ere found on elm trees 
in other to-ns of the San Joaeuin Valley, including kalaga , Selma, 
Kingshurg, Crosi, Snlta..e , Dinvba, Peedley, Sanger, Sur.nyside, 
CI o vis, and Yiselia. 
In the Zastem States t-o generations of beetles usually develop 
in one season. At bkesno aa^a.rently fonr generations developed 
last year vfcich resulted in the very rapid increase of the beetles.! 
Our long gro-ing season and the successive generations emtend the 
period of attach on elms over abort seven months. Control measures 
therefore, are much more difficult than under northern climatic con- 
ditions.
