Maheux (G.)- The Entomological Service of Quebec. — iSth Ann. Rept. 

 Entom. Soc. Ontario for 1917, Toronto, 1918, pp. 33-36. [Received

The author points out that while America is troubled by a far 

 greater number of insect pests than the Old World, the American 

 governments are always creating and organising various services for 

 the aid of the public and the agricultural community, while in Europe 

 private initiative is generally left to its own resources in dealing with 

 entomological problems. The history of the entomological service, 

 which has already created numerous bureaus in North America, is 

 briefly reviewed. The work undertaken in the Province of Quebec 

 is outlined, and includes inspections, propaganda, collections and 

 general work. It is suggested that a bye-law obliging every grower 

 to spray his crops would ensure better results. An Entomological 

 Society is now being organised in Quebec.

Fenusa (Metallus) hethunei (blackberry leaf-miner), which is closely 

 allied to F. (M.) rubi, was so numerous during 1917 that whole fields 

 of blackberries had a blighted appearance owing to the mining of the 

 leaves. There are two generations of this sawfly in a year. Adults 

 begin to appear about 1st July, eggs being laid in the tissues of the 

 leaves, chiefly near the midrib. The larvae mine the leaves, and about 

 the time the fruit is ripe they are full-grown and have begun to leave 

 the mines and enter the soil, where they pupate an inch or two below 

 the surface. Adults of the second generation begin to emerge after 

 two weeks and by 21st September are Very abimdant. Larvae of 

 the second generation hibernate in earthern cocoons in the soil. The 

 chief damage done is to weaken the plants and lessen the following 

 year's crop. The best method of control as yet known is the poisoning 

 of the adults with lead arsenate applied so heavily that it will remain 

 on the foliage a month or more. This should be done just before 

 blossoming or just after most of the blossoms are ofi^. 



Ceramica picta (zebra caterpillar), which is not generally very 

 numerous, has been abundant in many counties west of Toronto, 

 and has stripped many turnip fields of foliage, attacking also cabbage 

 and several other plants. The only remedial measure that has been 

 found satisfactory is dusting with Paris green mixed with 20 times 

 or more its bulk of air-slaked or hydrated lime, or land plaster [gypsumj. 

 Cydia (Carpocapsa) pomonella caused an unusual amount of side 

 injury to apples in the early part of the fruit season. A poison-spray 

 thoroughly applied three weeks after the blossoms fell gave good 

 results. Other moths recorded include Alypia octotrmculata (eight- 

 spotted forester), abundant on grape foliage near Toronto, and Datana 

 integerrima, which defoliated walnuts in Essex and Kent.

 a minor pest in Europe, is already sufficiently established in some
