24 THE KEPOET OF THE No. 36 



over the Province, though not in every orchard, by any means, but in every 

 district. 



Me. Gibson: Dr. Fletcher used to say that where you can find a pear tree 

 you will find a Blister Mite all over Canada. 



Mr. Caesar: It is probably found now more on the apple than on the pear. 



Anametis Grisea. Specimens of this Snout Beetle and of apple leaves in- 

 jured by it were sent this year from Albury, Prince Edward County, and Grafton, 

 Northumiberland County. In the latter place it was suspected also of feeding on 

 the bark of apple twigs. The beetles are nocturnal in their habits, so far as could 

 be learned. In the day time they hide under loose bark on the tree. Specimens 

 of injured leaves obtained at Albury, early in July, showed that they fed around 

 the margin, causing it to become very jagged. 



Pear Psylla (Psylla pyricola). It is several years since this tiny pest has 

 been so abundant in the Niagara district as this year. In many cases the spring 

 application of lime-sulphur should have been supplemented by the use of kerosene 

 emulsion soon after the leaves had opened. 



Pear and Cherry Slug (Eriocampoides limacina), Plate B, Fig. 5. Neglect 

 to control this pest has led to its becoming exceedingly abundant the last two years. 

 Many otherwise good cherry orchards have been rendered unsightly by the feeding 

 of the slugs on the leaves. Young trees are most subject to attack, and are usually 

 the ones most likely to be overlooked until the damage has been done. Plum trees 

 were attacked in some places, as well as sweet and sour cherries and pears. Arsenate 

 of lead readily controls the insect. 



€herry Fruit Fly (Rhagoletis cingulata), Plate A, Pigs. 3 and 4. When 

 the sour cherries were ripening I paid a visit to an orchard near Homer village, 

 where it was said some grub, evidently not that of the Plum Curculio, was to be 

 found in the cherries. As was suspected, the culprit proved to be the Cherry Fruit 

 Fly. Many adults, chiefly males, were seen on the leaves and fruit, and not a few 

 of them were captured with comparative ease. On examining the ripe fruit, mag- 

 gots, very like those of the Eailroad "Worm, were found inside, some of them nearly 

 or quite full grown. A few wormy cherries were brought back and put in a breed- 

 ing cage. On examination of the soil in the autumn eight puparia were found 

 about one inch below the surface. No experiments on control have been tried yet, 

 but evidently care should be taken to gather all the fruit, so that none of it may 

 fall to the ground and give the larvae a chance to escape into the soil. All wild 

 cherry trees in the neighbourhood should be cut down and burned, as these doubt- 

 less iserve as breeding quarters. Discing the orchard and allowing chickens to run 

 in it should be very helpful. Prof. Pettit, of Michigan, tells me that in that State 

 the pest seems to disappear almost entirely from time to time. This is encourag- 

 ing news, if it be true of Ontario as well as of Michigan. 



Mr. Caesar: Does anyone know of any other district where this pest occurs? 



Mr. Swaine : I have not heard of it down our way. 



Mr. Howitt : It is in New York State, especially on cherries which have gone 

 wild on the roadsides. 



Fruit Bark-beetles (Eccoptogastrr ruguJosus and Phleotrihus liminaris). 

 These troublesome little beetles are not nearly so abundant as they were a few years 

 ago. This apparently is to be attributed chiefly to the numerous parasites which 

 are found to be attacking them. There are clearly two broods of E. rugulosus, the 

 adults of the first appearing about the middle of June, and of the later brood about 

 the middle of August. This species is much more common than P. Uminnrif^.
