Fig. 697. — Periplaneta Australasia. 



The Rose Chafers are best hand-picked, though the process is 

 laborious. Like all bright-coloured insects they are sun-lovers, 

 and numbers may be captured with a net dexterously used ; 

 while others 

 may be shaken 

 from their 

 food - plants 

 during dull or rainy 

 weather. 



Cockroaches are 



omnivorous pests, 



very destructive to 



indoor fruit and 



flowers. Shoots and 



footstalks of Vines 



and P ear- trees, 



flowers and roots of 



orchids, and many 



other plants are 



affected. At one time 



there was only one 



species which caused serious trouble — Stylophyga (BZatta) 



orientalis. There are, however, four or five other illustrious 



foreigners recently introduced. Periplaneta australasia (Fig. 



697) is now very common ; it is a rich brown with yellow 



streaks and 

 margin. Then 

 there are P. 

 a7nericana{¥\g. 

 , a larger insect, 

 butlacking the yellow 

 streaks and border- 

 ing; Phyllodromia 

 gcrmanica (Fig. 699) ; 

 and Leucoph&a suri- 

 namensis. These are 

 best poisoned by 

 means of phosphorus 

 paste, Magic Paste, 

 or the Ballikinrain 

 preparation. 



Codlin Moth 



(Carpocapsa pomo- 



nella). — This is one 



of the most injurious of insects, and is remarkable alike for its 



wide geographical distribution and accommodating taste. Though 



it chiefly affects Apples, yet Pears, several of the stoned fruits,
