The smaller grubs are usually found feeding on the fibrous rootlets, often devouring them entirely or barking them so that they die. A seriously infested plant may be kicked out with the foot or easily pulled up, often with the fibrous root system eaten away. Undoubtedly a por- tion of the grubs feed closely about the main tap root and their feeding there will sometimes girdle the crown. The larger grubs are often found buried in the tap root, and this food seems to give them a more pinkish cast, giving rise to a common belief that two species of lar- vae are present. These beetles may be present in a patch for years and but little injury result from their attacks. In the weevil districts, un- der normal conditions, an infested patch will show a few sickly hills the first sea- son, small patches here and there dead the second season, and the patch rendered worthless the next spring. This affords one full crop in the usual system of cul- ture. A condition that is becoming quite common, however, is for the patch to be materially weakened the first season; and the second season, or the first expected to yield a full crop, the patch is absolutely worthless. Two factors render this condi- tion possible. The soil is often already infested with the grubs even though strawberries have not been grown on the ground previously, and again the beetles from older infested beds all about tend to concentrate on the new patch. Food Plants While the strawberry root weevil shows a decided preference for the strawberry, it is by no means confined to this food plant. The following list is c
