ENTOMOLOGICAL SOCIETY OF ONTARIO. 



drought prevailed, and did much harm to grass, oats and barley. The species which 

 were most abundant were Melanoplus femur-ruhrum, M. atlanis and M. bivittatus. 

 Cutworms (Fig. 11) were less complained of than usual, taking the province as a whole. 

 Hadena arctica and Hadena devastatrix 



occurred abundantly in the extreme west- 

 ern counties. Hessian fly was sent in 

 from the Muskoka district ; and also the 

 joint worm (Isosoma hordei),F\g. 12, the 

 latter attacking wheat and injuring it to 

 the extent of five per cent, at Meaford, 

 Ont.

Fodder Plants. — Under this head, undoubtedly the greatest damage was done by 

 {^tadshoppers, and farmers will do well next season to examine their grass lands early in 

 the season before the grass is too high, to see if there are many of the young, and 

 if so, to use one of the different "hopper-dozers" or oil pans which are used to such 

 good effect in the Western States. The Pea Moth has continued its injuries, and up to 

 the present no practical remedy has be^n discovered. I commend this insect to the 

 particular attention of our member.". Although known as so abundant and injurious 

 for the past twenty years, the perfect insect in this country has never yet been identified. 



Eoots. — The Colorado Potato-beetle still exists in great numbers, but with so cheap, 

 and effective a remedy as Paris green, it cannot be considered a serious enemy except by 

 the lazy or careless. The larva of Gortipia cataphracta was sent in from three or four 

 places in Eastern Ontario as having bored into the stalks of potatoes, tomatoes and 

 many other garden plants. A new attack on potatoes reported this year for the first 

 time was by Otiorhyuchus ovatus, which was sent from Fenella, Ont., by Mr. J. B. 

 Brook, who had found it girdling the stems of his potatoes. The same insect was 

 found injuring young apples, pears and currants at Arthabaskaville, Que. Turnips 

 were badly attacked all over the province by the Turnip Aphis, and many reports were 

 received. There is no very satisfactory remedy for this insect. Careful watch should 

 be kept in August when hoeing and thiuning turnips At that time the colonies are 

 small and iew in number, and if care be taken to destroy them then, much may be 

 done to control the outbreak. Spraying with kerosene emulsion was found to be 

 useful when the colonies were not too numerous. A tobacco and soap wash would be 

 equally effective. The Diamond-back Moth (P/^^eZ/a cruciferarum) was als) abundant 

 both on turnips and cabbages, but affected the crop very little. Cibbage and Onion 

 Root-maggots were as usual abundant in many places, and did much harm. The 

 Imported White Cabbage Butterfly {Pieris rapce), Fig. 13, is not now considered a very 



serious enemy where the use of pyrethrum powder 

 and flour (one to four) is practised. The best way 

 to apply the remedy is to dust it over the cabbages 

 as soon as the work of the larvae is noticed, by 

 means of small hand bellows or from a muslin bag. 

 It cannot be too strongly insisted upon that Paris 

 green must never be used on cabbages. 



Fruits. — The injuries to fruits cannot be said, 

 as compared with other years, to have been very 

 serious. Most of the usual pests have put in an 

 appearance and done some harm, but the more 

 ge.''eral adoption of the excellent practice of spraying regularly is having a noticeable
