STRAWBERRY. GREEN ROSE CHAFER.

would be worth trying as an experiment, to be carried out 

 further if many maggots were found ; by throwing some of 

 the removed earth into a large tub of water it would be seen 

 directly whether there were either maggots or beetles present. 



Small plants may have their roots washed out, and thus be 

 saved ; but the ground on which they grow should be 

 thoroughly dealt with at once. A good handful of fresh gas- 

 lime put into each hole at once is a good cure for what evil 

 may remain. 



These pests should be looked to on their very first appear- 

 ance, for they are most difficult to get rid of, and, as in many 

 other cases, even severe cold has little effect on the maggots. 

 From experiments in my own garden I found they would 

 stand a temperature as low as 11 "8", that is, just over twenty 

 degrees of frost, without being (as far as could be seen) in the 

 least injured. 



STKAWBERRY. 



Green Rose Chafer. Cctonia aurata, Lmu, 





Larva ; back of pupa ; cocoon ; and beetle. 



This chafer is injurious both in the larval and perfect state. 

 In the first — that is, as a grub — it feeds on the roots of Straw- 

 berries, Grass, and other plants; as a beetle it frequents 

 many kinds of flowers, including the Eose, from which it 

 takes one of its names ; but is more especially injurious by 

 its attacks on Strawberry blossom, and to the flowers of 

 Turnips left for seed, where it eats oft" the anthers from the 

 stamens and thus renders the flowers abortive.
