A Melon Pest {Prionus sp.)- Larvae of a Prionus beetle caused 

 more or less serious damage by attacking the roots of watermelon 

 vines in Roosevelt County. 



Flea Beetles {Epitrix suhcrinita Lee, Phyllotreta alhionica Lee, 

 Psylloides punculata Melsh., Disonycha triangularis Say). Various 

 species of flea beetles caused considerable early damage to garden 

 truck generally over the State during the past season. 



Blister Beetles (Epicauta maculata Say and Lytta nutalli Say). 

 These two species of blister beetles were especially abundant, accounted 

 for by the abundance of grasshopper eggs on which their j^oung de- 

 velop. The adults themselves are often injurious to alfalfa and garden 

 truck. 



Plum Curculio (Conoirachelus nenuphar Herbst). A few apples 

 ])rought in from an orchard near Hamilton at picking time showed the 

 typical scar injury of the plum curculro. As these were the only ap- 

 ples seen which showed this injury, it is probable that this insect 

 has not yet become widely established in the Bitter Root Valley. 



A New Strawberry Pest {Baris carhonaria Blatchley). Mention 

 was made in the State Entomologist's report for last year of an insect 

 which caused serious damage by boring in the crowns of young straw- 

 berry plants. Several larvae feeding within the crowns were reared 

 to adults and the above determination on a single specimen was made 

 by Mr. C. W. Leng who states that there is no former report of this 

 genus attacking strawberry. (Some doubt as to the exact species is 

 entertained until more specimens are examined.) 



BEES, WASPS, ETC. (HYMENOPTERA) 

 Yellow Jackets (Vespidae). These insects were reported to have 



caused some loss to one individual by feeding on raspberries. 



Thread-Waisted Wasps {Sphex communis Cress.). Large num 



bers of these insects found clustered on wheat heads during the first 



few days in July were sent to us from widely separated sections of 



the State. 



INSECT PESTS OF 1922 

 MITES AND TICKS (ACARINA) 

 Pear-Leaf Blister-Mite {Eriophyes pyri Pgst.) On account of 

 a more general use of control measures against this pest in 1922 much 

 less damage occurred than in the previous year.
