xruit interests. The experiences of fruitgrowers with this insect 

 affords some light on these questions. The following statements 

 obtained by personal interview with individual growers are but a 

 few secured reporting the occurrence uf this pest in their orchards. 

 Those chosen for publication bring out some special phases of the 

 subject: as length of time the tlirips has been destructive in the 

 community, nature and extent of injuries, varieties of fruit af- 

 fected ; in short, such notes as will in any way afford light on the 

 occurrence and behavior of the thrips in their respective plant- 

 ings. 



Edmund Bunk, Germantown. — Kieffer blossoms' and some leaves turn 

 brown about the time of blossoming, and believed the trouble was due to 

 frost. First saw the blighting in 1910. 



M. M. RiVENBURGH, Gemiantown. — Seckels have always been the 

 most injured and during the past five years have had only one fair crop. 

 Should have from 75 to 100 barrels of fruit, but since this pest appeared 

 have harvested only about 10 barrels each year. In 1910 the crop was only 

 2 barrels. Kieflfers have suffered losses next in importance to the Seckels, 

 running from one-third to two-thirds of a crop on many trees, the injury 

 increasing each year until this year. The injuries to Bartletts and Clapp 

 Favorites have only been slight as yet. About the time of blossoming the 

 trees most severely attacked turn brown. Have always thought that the 

 injury was due to frost or to use of spraying mixtures. 



Peter Fingar, North Germantown. — In 1910 Kieffers turned brown as if 

 burned; the leaves fell and later the fruits so that the trees looked as if in 

 winter. My loss was probably one-half of the crop. Later on the leaves 

 came out but the trees did not produce many fruit buds and thus shortened 

 the crop for this year. Same injuries to a less extent on Clapp Favorites 

 and Bartletts. Heard of the sanie trouble on Seckels over three years ago. 



EoY Lasher, Germantown. — Have had good crops of Kieffers until 1910 

 when the yield was practically a failure. About blossoming time trees ap- 

 peared as "if they were blighted. Leaves and blossoms dropped and later a 

 new crop of leaves appeared. The unfavorable conditions of the trees were 

 generally attributed to frosts or spraying mixtures. 



Clarence Snyder, North Germantown. — Blossom and leaf clusters turned 

 brown about blossoming time in 1910, causing, a loss of over half the crop. 

 Some trees were late in getting another crop of leaves. Principal injuries 

 are to Kieffers, and the trees most seriously affected in 1910 show this 

 year little or no fruit and less than the normal amount of foliage. 



C. A. Lasher, Germantown. — First noticed injuries to blossom buds In 

 1910 when varieties such as Seckel, Bartlett, Beurre Bosc, Vermont Beauty 

 and Dana Hovey were attacked. The pest was most destructive to Seckels 

 and caused a loss of over two-thirds of the crop. 



Webster Coons, Germantown. — Injuries were first noticed on Kieffers 

 last year when the trees at time of blossoming had the appearance of being 

 Bwept by fire. The loss was about two-thirds of a crop.
