affected to any appreciable extent, and it is therefore recommended to 

 be planted following a crop of infected strawberry plants.* 



Rumex acetosella, a common weed in strawberry plantations, is 

 also fed upon by the larvae of this weevil. It was curious to note that 

 roots of this weed intermingling in the row with the roots of the straw- 

 berry plant, were chosen by the larvae for food in preference. This indi- 

 cates the impartiality and general feeding characteristics of the larvae. 

 Besides these few notes, literature on this weevil shows that the fol- 

 lowing plants have been recorded as attacked by the larvae : Roots of 

 cultivated strawberry, blue grass, Potentilla glandulosa, Balsamorhiza 

 sagatata, timothy grass, Poa cerotine, Poa pratensis, and white clover. 



Food Habits of Adult. 



During this past summer, adults were seen feeding directly upon 

 the fruit of the strawberry, on the fruit of the raspberry, on the vine, 

 on a fallen peach on the ground, and also on a fallen apple. The 

 foliage of the strawberry plant is devoured, but not, in my opinion, to 

 any appreciable extent. 



In literature further records are as follows: Foliage of raspberry 

 and of the potato, both under natural conditions. Miss Patch, of 

 Maine, has given a long list of plants fed to adults in confiement, which 

 clearly shows that under laboratory conditions any kind of vegetation 

 will offer itself as food to this insect. 



Susceptibility of Variety. 



From the foregoing account of the feeding habits, larval and adult, 

 I feel safe in claiming that no susceptibility of any one variety of straw- 

 berry over any other exists, and vice versa, no immunity from attack 

 can be claimed by any variety of strawberry. This point is further 

 borne out by observation in the field. Certain varieties of strawberries 

 may resist an attack better than others, but this degree of resistance 

 is not resultant upon any standard of immunity possessed by the variety 

 so much as by the productivity and vegetative capabilities of that variety, 

 viz., deep rooted and vigorous varieties, capable of producing a num- 

 ber of runners, which throw the heaviest yield the first spring from 

 planting. The varieties recommended in this regard from Lower 

 Fraser conditions are the Dunlap, Wilson, Warfield, Williams, and 

 William Belt. The varieties not so suited are the Magoon, Clarke's 

 Seedling, Jessie, and the Marshall. 



•The inference is not intended that red or crimson clover is immune from attack, but 

 rather that it is able to withstand an attack without apparent injury to itself.
