B. C. E\TO,MOLOGICAh PROCEEDINGS, 1911. 13 



I have iioticeti for the first time in my recollection a black aphis 

 attacking the Rluibarh, Cucumber and also one on the Holl\. While up 

 Mount Cheam 1 again noted a black aphis present in large numbers. 

 1 am unable to say to what species any of these aphids belong. The 

 green aphis was not very troublesome this year, but the Wooly Aphid 

 was \ery prevalent. 



I have noted further that the spittle insects, Cercopidae, caused a 

 great deal of annoyance to flower gardens here in Vancouver. 



I trust these few remarks will be of interest.

The season just closed has been fruitful in demonstrating that at 

 least one insect which is usually considered a bad pest and one that it is 

 necessary to destroy by spraying, can at least prove a blessing in disguise. 

 I refer in this case to the Black Cherry Aphis, Alyziis ccrasi. This 

 insect made its appearance in large numbers at the commencement of 

 July and as usual attacked the tips of the sweet cherries. So bad was 

 the infestation that in some cases the fruit required washing before being 

 marketable, as the brood had spread all over the trees. The main brood 

 was, as previously stated, securely placed in the curled up leaves at the 

 tips of the young shoots. Here thei,' remained for o\ er a month, and at 

 the end of that time died. 'Fhe foliage all turned black, greatly dis- 

 figuring the trees. E.xamination of the young shoots revealed the fact, 

 that but few of the shoots were killed, and that the infestation had 

 residted in retarding the excessive growth which it might have been 

 necessary to remove by pruning. The aphis had most effectually checked 

 the excessive growth and had left the buds on the season's growth in fine 

 healthy condition. No summer pruning could have so markedly im- 

 proved the trees as did this aphis infestation. I must not, however, be 

 quoted as an advocate of the propagation of this insect, to do the work 

 which is required in summer pruning, but I onl\ cite this as an instance 

 where out of evil good may come. 



The white maggots attacking the roots of the cauliflower in the early 

 spring months were the cause of great loss to the market gardener. 

 During June and early July we had a remarkable infestation of cut- 

 worms several varieties were greatly in evidence, but the most common 

 were the lar\-ae of M/uiicstrii cantulinsh. These not onl\- attacked the
