is very prolific. More than one liimdred eggs liave been found on a single alfalfa 

 plant. Though most abundant in spring and early summer, tliey may be found 

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

 They winter as mature beetles 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 cars, and as the Salt Lake road runs direct from an infested 

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

 against this dreaded pest. 



We must all become acquainted with this insect (see Bulletin from Depart- 

 ment of Agriculture, No. 137), and keep close vigil of all alfalfa fields, especially 

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

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

 must be repeated. There must be no half-way work or trifling in case of any 

 one of these three pests.
