Insects Attacking Cereals and Grasses. 



White Grubs and Wireworms. Many complaints were received of injury to 

 grain crops and potatoes by these larvge, especially from Western Ontario. 



Hessian Fly (Mayetiola destructor). The Hessian Fly has in many dis- 

 tricts been unusually destructive. As soon as I saw that some wheat fields had 

 as many as fifty per cent, of the plants destroyed, I sent out a circular letter 

 outlining the most up-to-date methods of control. As the wet weather prevented 

 almost any early sowing, it will be interesting to see the result next year. Many 

 parasites were found to be present, but whether they would be in sufficient number 

 to control the flies next year unaided is very doubtful. They are easier to rear 

 than the He&sian Fly and are apparently present in considerable numbers almost 

 every year. 



Grasshoppers. In spite of the wet season grasshoppers were very destructive 

 in a few districts, and especially in parts of Norfolk County. • 



Eare or Uncommon Insects. 



Alabama argillacea. Large numbers of this moth were seen around electric 

 lights at Woodstock on Oct. 11. Specimens were sent to me by Mr. James Dunlop

-Asparagus Beetle: a, adult; &, egg; c, young larva; d, full-grown larva; e, pupa. 



of that town, who said that at some posts they could have been shovelled up like 

 ,a swarm of bees. Last year it will be remembered we had also a visit from 

 these Southern moths. 



Typhoea funiata. This little brown beetle, belonging to the family Myceto- 

 phagidae, was sent to me by the "Farmer's Advocate" from a man who said that 

 for two years it bad been injuring the wheat in his granary and had caused it 

 to heat. Whether it was the real cause of the heating I do not know, but believe 

 it is worth while recording this beetle as a granary pest in the Province, since 

 it is rarely, if ever, mentioned in any Canadian reports on granary insects. 



Maple Leaf-roller (Cenopis pettitana). A correspondent at Kenmore, near 

 Ottawa, sent me specimens of the larvge which he said were injuring the foliage 

 of his sugar maple woods greatly. I reared the adults and sent specimens to 

 Mr. Gibson, Ottawa, who identified them as Cenopis pettitana. Mr. Baker and 

 I also obtained larvae from elm trees in the Niagara District. The adults from 

 maple and elm looked to be the same and Mr. Gibson could see no difference. 



Tortrix confUctana. Mr. Baker found this species in great albundance in 

 Toronto. Mr. Gibson kindly identified it for him.
