is very prolific. Mon- than one liiiiulrcd opgs Imvc l)c<-n found on a .single nlfalfn 

 plant. Tliough nio.st alxindant in .spring and early sunnner, tlii-y may be found 

 as eggs and larvae well into the fall. Hotli larva and imago feed on the plants. 

 They winter as mature heetles and .so are easily introduced into new localities 

 by the transporting of alfalfa hay. The weevils have often been found in cars, 

 even the sleeping ears, and as the Salt Lake road runs direct from an infested 

 region to our own Southern California, it is hard to sec just how we can quarantine 

 against this dri'aded pest. 



We must all become ae(|uaiiited with this insect (see Bulletin from Depart- 

 ment of Agriculture, No. I.S7), and keep close vigil of all alfalfa fields, especially 

 those along the Salt Lake Railroad, that any infestation may Iw quickly and 

 thoroughly exterminated. The splendid work against the White Fly in such case 

 nnist be re|)ealed. There must be no half-way work or triHing in case of any 

 one of these three pests.
