The organisation of the entomologi(;al section is explained. 

 Attempts have been made to popularise scientific knowledge for 

 the use of agriculturalists and growers by means of articles in the daily 

 papers and by the publication of special bulletins.

Insect pests of vegetables during the year 1917-1918 included the 

 usual enemies of kitchen-gardens. Isolated attacks occurred of 

 Phorbia Jusciceps, Zett., on young beans, Bniclius pisorum, L. (pea 

 weevil), Psila rosae, L. (carrot fly), Ceramica {Mamestra) picla, Harr. 

 (zebra caterpillar) and Crioceris asparagi, L. (asparagus beetle). 

 Measures were taken against Agrotis {Noctua) fennica, Tausch. (black 

 army worm), mentioned in the preceding report as having done 

 considerable damage, and another cutworm, Hadena devastatrm, 

 Brace, which destroyed large fields of cereals in another locality. 



Fruit pests included Aphis mali, F. (green aphis), Cydia (Carpocapsa) 

 pomonella, L. (codling moth), and Hemerocampa leucostigma, S. & A. 

 (white-marked tussock moth). Gooseberry and currant bushes Avere 

 attacked by Pteronua ribesii, Scop, (currant sawfly) and an Aphid, 

 Mgzus ribis, L.

Some account is given of the Geometrid, Amphidasis cognataria, 

 Gn., which the author has found feeding on plum trees, currant bushes 

 and on sweet clover, Melilotus alba. Slingerland and Crosby's descrip- 

 tion of the insect and its life-history are quoted. Arsenical poisons are 

 successful in keeping this moth in check.

There is considerable difference of opinion as to whether calcium 

 arsenate is a safe insecticide to use with lime-sulphur. The author's 

 experience has been that f lb. used with 40 gals, diluted lime-sulphur 

 does not cause any injury. It has also been used at a strength of 10 

 per cent, as a dust mixture with equal parts of sulphur and talc. 

 With Bordeaux mixture on potatoes it is superior to Paris green or 

 lead arsenate. It cannot, however, be used alone. It is proposed 

 to test this substance over a period of five years and compare it with 

 lead arsenate. High grade calcium hydrated lime is recommended 

 as superior to stone or quick lime for insecticidal purposes. 



Dust spraying proved almost doubly as expensive as the use of 

 liquids, but both methods have produced perfect fruit and foUage. 

 It is thought that when the cost of dusting has been reduced and 

 experience has produced better mixtures, dusting will become far
