June, '22 marcovitch: strawberry weevil 245 



or less across, and the pedicels about y^ of an inch. The cut squares 

 were examined, but no eggs could be found. 



This is in accord with observations made by the writer in Minnesota. 

 There it was found that newly emerged weevils when given fresh buds 

 would girdle them; but in no single instance could eggs be found. It 

 was also learned upon dissection that recently emerged weevils do not 

 contain eggs and are therefore unable to oviposit the same season. It 

 should be noted that newly emerged weevils were used in the cages 

 with the tomato plants. What effect old laying weevils would have 

 on tomato and cotton buds has not been determined. The old weevils 

 have probably all disappeared when cotton squares are put out in the 

 field. 



It may be of interest to report here some observations made on other 

 food plants of the weevil that are already known. On March 18, 

 1921, the buds of the redbud tree, Cercis canadensis, were found cut in 

 West Tennessee. The injured buds were smaller and shnvelled, as 

 in the case of the apple, and contained eggs. 



On April 29, 1920, the buds of the yellow-flowered cinquefoil, Poten- 

 tilla canadensis, were observed to be severed at Knoxville. Thpse 

 contained eggs from which adults emerged June 2. 



Wild blackberry buds were found cut May 4 at Knoxville. These 

 were placed in a breeding jar and adults were obtained June 7. 



On June 1, 1921, the weevils were reported to have destroyed prac- 

 tically all of the roses at Curve, Tennessee. Professcr Sherman also" 

 records the weevil as breeding in and cutting the buds of the roses 

 at Wallace, North Carolina, in 1904. 



On April 16, 1920, adults of the strawberry weevil were found in the 

 flowers of the common dogwood. When okra comes into flower, they 

 may be found there too. Frost records the strawberry weevil in the 

 flowers of Vacciniums, while Hamilton states that he found them in 

 flowers of Tilia and Rhus. 



With our present knowledge of the food habits of the strawberry 

 weevil, it may be stated that certain plants are used for breeding pur- 

 poses : namely, the strawberry, blackberry, dewberry, raspberry, yellow- 

 flowered cinquefoil, redbud tree, rose, and apple. Other plants, like 

 the tomato, horse nettle, and cotton, may have their buds cut, but no 

 eggs deposited in them. Finally, the weevil may visit a great variety 

 of plants, such as the dogwood, okra, blueberry, and sumach during 

 their flowering period to obtain pollen.
