INSECTS INJURIOUS TO THE STRAWBERRY. 



By W. Saunders, London, Ont. 



1. The Strawberry Root or Crown Borer 



(Anarda lineakUa, Zeller). 



2. The White Grub {Lar.hnnsterna quercina, 



Knoch).

fragaria, Riley). 



4. A second Strawberry Leaf-Roller (Einr- 



iema permuiulana, Clemens). 

 i. A third Strawberry Leaf- Roller {LozoUe- 

 nia fragaria n a, Packard). 



6. Other Strawberry Leaf-Rollers. 



7. A Cut Worm {Agrnfis). 



8. The Measuring Worm {AngtronM 



crocaolaria). 

 0. The Smeared Dagger (Arronyda nhlinHtf. 



Sm. & Abb.).

maculatus, Norton). 

 IL Osniia Canadensis, Cresson. 

 12. A Strawberry Bug {Cmmelaen/i 1) 



Fortunately, there are not many insects injurious to this useful and now extensively 

 cidtivated fruit. It has, however, several special foes, which have in some localities at 

 times proved troublesome, and there are a few other general feeding insects, which tak« 

 to strawberry, if it lie in their path, as readily as they will to any other green thing they 

 may meet with. Still, in any case, the strawberry grower must not look upon in.sects a« 

 an unmixed evil, admitting of no toleration, for he would find it very difficult indeed tw 

 .secure a good crop without their aid. In .some varieties of strawberries, tlie flowers ar« 

 more or less imperfect, the male organs being more fully developed in some, the femaU 

 oigans in others, so that fertilization can rarely take place, excepting through the agency 

 of insects, who visit flower after flower, and carry and scatter the fertilizing pollen witk 

 them wherever they go ; and even with the perfect flowers their presence and unconscious 

 labour is required to ensure a liberal crop of well formed fruit. 



AFFECTING THE ROOT. 



The Strawberry Root or Crown Borer (Anarsia lineaUlla, Zeller). 



This is a very troublesome insect where it occurs plentifully, and takes a liking t» 

 the strnwberry ; but, happily, this is not often the case. We have never seen it affecting 

 this fruit anywhere excepting on the grounds of Mr. Luke Bishop, of St. Thoma.s, Ont., 

 who first called our attention to it about the miildle of May, 18()9, when he brought us « 

 few specimens. During 18fi8 and 1860, they played s.ad havoc with his plants, destroying 

 a large proportion of tlieni. We believe tlicy have been less troublesome since. Th» 

 borer is a sn\all grub or catei-pillar, nearly halfan incli long, and of a reddi.sh colour, which 

 eats irregular channels in various diriotions, through the crown and larger roots of the 

 plant, causing it eitiier to wither and die, or cl.se to send up weakened and almost Imrron 

 ■■shoots.
