26 B. C. ENTOMOLOGICAL PROCEEDINGS, 1011. 



the larva durinf!; the present year on bulbs imported into Ontario from 

 Holland. It had been previously captured on Mount Royal, Montreal, 

 by Mr. A. Chagnon in 1903. In British Columbia, it is now a serious 

 pest of bulbs, and Mr. A. E. Wallace reported it as attacking narcissus 

 and daffodil bulbs near Victoria, B. C, about 50,000 bulbs having been 

 destroyed in the year. Mr. P. Norman has kindly furnished me with 

 particulars as to many of its habits in that locality which was visited 

 in October. 



The perfect insect is seen from March to September, and appears 

 to begin to breed in May. The eggs are probably deposited in the 

 centre of the leaf crown. The larva are found in the centre of the 

 bulb, having made their entrance through the base of the bulb. The 

 bulbs are destroyed by the larva or maggots eating away the flattened 

 stem at the base of the bulb and afterwards destroying the centre of the 

 bulb. Professor Ritzema Bos, State Entomologist of Holland, who has 

 written a complete account of this insect, records the eggs as being laid 

 in the soil near the foliage. He informs me that it attacks chiefly 

 Nairhsus tagetta in Holland. Mr. Norman has observed that the early 

 varieties of daffodils, 'Princeps,' 'Golden Spur' and 'Henry Irving,' are 

 not attacked and that such varieties of narcissus as A', pocticiis oruatus 

 and N. p. poiinniin suffer considerably. The method of eradication 

 which has been found most simple and efficient in Europe is the annual 

 lifting of the bulbs and the destruction of all those which are found to 

 be attacked by the maggots, as can readily be seen. This method has 

 been found effective in England, and also, Professor Ritzema informs 

 me, in Holland. Soaking in water is of no value and the destruction of 

 the pupae in the soil by the removal of the latter in the spring is im- 

 practicable in a large scale. Satisfactory results may possibly be ob- 

 tained by poisoning the adult flies with sweetened arsenical baits, and 

 experiments on this are being carried on in British Columbia."
