1904 ENTOMOLOGICAL SOCIETY. 29 



The Plum and Apple Curculios were abundant throughout the Pro- 

 vince. In the Winona district, where spraying was altogether neglected, 

 the plum crop was very seriously damaged. 



The Apple Curculio was most destructive in orchards that had been m 

 sod for a period of years. In one orchard it was noticed that the pear trees 

 m a row next to an open drain, which had not been cleaned out for some 

 time, being full of leaves, etc., were badly attacked by the Curculio, while 

 the trees in the centre of the orchard, where the ground had been cultivated, 

 were entirely free from the pest. 



The Peach Borer was reported as being abundant in several portions of 

 the peach areas. 



The Grape Thrips were unusually abundant in the vineyards of the 

 Winona district. As a rule nothing was done to control them, and little 

 harm seems to have been done by them. 



Insects of the Garden. 



The Raspberry Saw-Fly (Monophadnus ruhi). This insect does not 

 often call for attention, but this year reports came in early in June from a 

 'large grower near Fonthill that "numberless green larvae were devouring 

 the leaves of raspberries". An application of Paris Green put a stop to 

 their ravages. 



Wireworms did considerable damage near Burlington by destroying 

 acres of melons^ and tomatoes. The plants would make a good start, but 

 in a few days they would turn yellow and wilt. When such sickly-look- 

 ing plants were pulled wireworms were found on the root stock. 



Cabbage Root-Maggots continue their depredation year after year with- 

 'out apparent hindrance. Many growers of cabbages confine their patches 

 to clay soil, for they found that nearly every plant succumbed on sandy 

 soil. It seems strange that growers will not take the trouble to apply the 

 tar-disk when the plants are set out, or to use one of the many solutions 

 which are at least partially effective. They prefer to replant rather than 

 go to the trouble and expense of using preventive measures. 



The Onion Root Maggot was also very destructive this past season. 

 This pest is even more difficult to treat than the Cabbage Root Maggot, 

 but good results can be secured by the use of a solution of insect powder, 

 or by Cook's Carbolic Wash. 



The Carrot Rust-Fly (Psila roso') was severe at Barrie this season, and 

 many specimens were sent to me which showed the characteristic rusty 

 colored channels on the roots. This insect winters over in the ground ^'n 

 a puparium, and the winged flies emerge in spring to lay their eggs on the 

 young carrots. Late sowing seems to be the most practicable treatment, 

 for, although washes may be used to advantage, few growers will take the 

 trouble to treat their carrots. 



Currant Worms (Nematus rihesii) were very abundant on gooseberries 

 and currants. Many cases are reported where the bushes were completely 

 stripped of their leaves before the owner was aware of the presence of the 

 worms. 



Potato Beetles (Doryphora decemlineata) were reported as being more 

 abundant than usual. 



Asparagus Beetles are plentiful in the southwest section of the Pro- 

 vince. The 12-spotted species {Crioceris 12-punctata) is by far the more 

 abundant species, although in the Niagara region the other form is more 

 numerous.
