beetles had already begun to disappear. Several acres of, waste sandy land lying 

 alongside the infested vineyards showed ideal conditions for bringing about just 

 such an outbreak. 



Imported Red Spider (Tetranychus pilosus). This spider was found as far 

 east this year as Trenton. It continues to do considerable injury, especially to 

 European plums.. Some trees, however, that were badly infested last year were 

 only lightly attacked this year. Moreover, in some apple orchards trees heavily 

 infested just before bloom were comparatively lightly infested a couple of weeks 

 later. It is very probable that weather conditions have a very important part in 

 the control of this pest as of so many others. 



Grape-vine Flea-beetle {Haltica chahjhea) . There were again many com- 

 plaints of injury from this beetle, especially in the Niagara district. 



Grape Leaf-hopper {Typhlocyba comes). This insect was very abundant 

 in the Niagara district. Eed grapes were, so far as I observed, much worse attacked 

 than blue. The foliage on many of the former in September was so brown from 

 injuries that one would expect the fruit at picking time to be inferior in quality. 

 I have had no opportunity to test whether this was so. 



Raspberry Saw-fly {Monophadnus rubi). This raspberry pest is very wide- 

 spread in the Province and has the last few years been doing more damage than 

 usual. One large raspberry plantation near Vineland was almost completely de- 

 foliated by it this year. 



Imported Currant-Borer {Aegeria tipuliformis) . Almost every currant 

 plantation is infested by this borer. In some cases a very large number of the 

 canes are found to be attacked. 



Glassy Cutworm {Hadena devastatnx). Last autumn at our annual meet- 

 ing I reported that some fields of wheat had been badly injured by this cutworm. 

 The caterpillars in November last varied in length from about I/2 to 1 inch ; hence 

 we expected these over-wintering caterpillars, where numerous, to do much damage. 

 As soon as growth began in spring reports started to come in of fields of wheat and 

 barley being attacked. Several fields of wheat were almost ruined by the severity 

 of the attacks. A few Army- worms, but only a very few, were found among the 

 cutworms. As the Glassy Cutworm works under the surface of the soil farmers 

 were advised to use the poisoned bran, harrowing it into the soil in the evening. 

 I did not receive any reliable accounts of the degi'ee of success obtained. About 

 the usual number of reports of damage by other kinds of cutworms here and there 

 throughout the Province were received. 



Strawberry Weevil (Anthonomus signatus). A few more complaints than 

 usual were sent in of injuries from these insects. 



Imported Onion Maggot (Pegomyia ceparum). It is worth recording that 

 in the great onion marshes of Kent County I ccaild scarcely find a root maggot 

 when visiting the district this summer. Growers tell me they are never troubled 

 by it. This is strange, because onions have been grown on these marshes for at 

 least fifteen years, and, as the Onion Maggot is a very troublesome pest in many 

 parts of the Province, one would expect it to do even more damage in the marshes 

 where onions are grown on a larger scale tban anywhere else in Ontario. 



Slugs. In Oxford County the district representative stated that Slugs were 

 so abundant this spring that some farmers claimed they were destroying the corn 

 just as it was coming or had come through the ground. 



Millipedes. Last year, but more especially this year, Millipedes were very 

 abundant and several correspondents asked for methods of destroying them. Some 

 work was done in testing different substances. Of these tobacco seemed the most
