FOOD PLANTS OF THE SAN JOSE SCALE (Aspidiotus per- 

 Niciosus) IN OHIO, EXCLUSIVE OF FRUIT TREES. 



BY F. M. WEBSTER, WOOSTER, OHIO. 



The following list includes forest and ornamental trees and shrubs, 

 upon which the San Jose scale has been found breeding in Ohio*. 

 Nearly all of these have been found either by myself or my assistant, Mr. 

 C. W. Mally, in sufficient numbers to indicate that the insect might 

 thrive on any of tliem. The Cotoneaster was sent for inspection, it hav- 

 ing been recently received from a Long Island nursery firm, and when 

 received was literally covered with the scale : 



Grape, Viti^ labrusca. Willow (im])orted), Salix venninalis. 



Linden, Tilia Americana. Cut-leafed Birch, Betula, sp. 



European Linden, Tilia Europcea. Lombardy Poplar, Populus dilatata. 

 Sumac, Rhus giabra. Carolina Poplar, P. inonilifera. 



Japan Quince, Pyrtis japonica. Golden-leaf Poplar, P. Van Geerti. 



Cotoneaster, C. frigiihim. Catali)a, C. speciosa. 



Flowering Peach, Prunus, sp. Chestnut, Castanea sativa. 



Flowering Cherry, Primus., sp. Osage Orange, Madura aurantiaca. 



American Elm, Ulmus Americana. Snowball, Viburnum opulus. 

 Black Walnut, Juglans nigra. 



To these must be added the several varieties of roses, currants, 

 gooseberries and raspberries. The Early Richmond cherry I believe to 

 be exempt from attack, as I have found trees whose branches interlocked 

 willi those of a pear that had been killed by the scale, yet the cherry was 

 uninfested ; and in two cases that came under my observation, where this 

 variety of cherry had been grafted upon mahaleb stock, and shoots had 

 sprung up from below the graft, the shoots were badly infested with scale, 

 while none at all could be found on the trees themselves.
