cherries ; Eucosma {Tmetocera) ocellana (bud moth) ; OxygrapJm 

 {Acleris) minuta (lesser apple leaf-roller) ; Schizura concinna (red- 

 humped apple worm) ; Datana ministra (yellow-necked apple cater- 

 pillar) ; Hyphantria cunea (fall webworm) ; Taeniothrips inconsequens 

 (pear thrips), which is recorded for the first time in Ontario. Fennsa 

 (Metallvs) bethimei or F. (M.) ruhi (blackberry leaf-miner) was very 

 abundant, but all attempted remedial measures failed. Anthononms 

 signatus (strawberry weevil) caused the destruction of 30 to 50% of 

 the crop ; in certain districts it was checked by a heavy application 

 of a dust consisting of 80 parts of sulphur, 10 parts lead arsenate and 

 10 parts of some diluent. Ancylis comptana (strawberry leaf-roller) 

 and Tetranychus telarius (red spider) were also abundant. 



Insects recorded as injurious to vegetable crops include : PJiorhia 

 {Chortophila) brassicae (cabbage root-maggot) on cabbage, cauliflower, 

 radishes and turnips ; P. fusciceps (seed corn maggot) ; P. vicina (beet 

 leaf- miner) ; Hylemyia antiqua (onion maggot) ; Pieris [Pontia) ravae 

 (cabbage worm), which was unusually abundant ; Depressaria 

 lieracleana (parsnip webworm) ; Psylla rosae (carrot rust fly) and cut- 

 worms. Pests of field crops were not numerous, those recorded 

 including : Thecodiplosis mosellana, Gehin (wheat midge) ; Mayetiola 

 destmctor (Hessian fly) ; Isosoma tritici (wheat joint-worm) and a 

 wireworm, Agriotes mancus. Other miscellaneous pests include : 

 Neocerata (Dasyneura) rhodophaga (rose midge) ; Tortrix (Cacoecia) 

 rosaceana (rose leaf-roller) ; undetermined Nematodes on cyclamen ; 

 Chermes ahietis and C. similis causing galls on spruce trees ; and Lyctus 

 striatns (powder post beetle), which was found seriously damaging oak 

 floors and furniture.

During the year under review the most serious damage was caused by 

 Epitrix ci(cumeris (potato flea-beetle) to potatoes and tomatoes, and

 Entom. Soc. Ontario 1918 ; Toronto, 1919, pp. 28-32. [Received 

 28th October 1919.] 



A popular account is given of the economic value of Aphids as gall- 

 makers and their importance as agricultural pests. The species dealt 

 with include Melaphis chinensis, the galls of which are used in the 

 manufacture of ink and dyes. The factors controlling the appearance 

 of alate and apterous generations, as well as studies on the pre- 

 determination of sex, are discussed.
