RASPBERRY AND STRAWBERRY PESTS. K^l 



their movements; as the httle inisects are very much on 

 the alert on fine, sunny days, taking to flight on the least 

 movement of the bushes. Frequent spraying with some 

 wash, like No. 16, which would render the unopened 

 flower-buds unpalatable to the beetles, would, no doubt, 

 if carried out regularly and quite early in the season, save 

 the blossoms to a certain extent. Much may be done to 

 prevent a recurrence of this most destructive infestation 

 by clearing away and burning all old w^ood from the 

 bushes, and any twigs and leaves near them on the 

 ground, that might afford harbourage for the pupa^. 



Raspberry Gall Fly (Lasioptera rubi).— A gall 

 midge, the larvae of which bore into the epidermis of the 

 shoots and cause galls, or swellings, to form. The female 

 midge lays its eggs at the base of the shoots or buds in 

 early summer. *'•" 



PiEMEDY. — All slioots fumished with galls or swollen 

 parts should be cut off and burnt. 



Raspberry Moth (Lampronia rubiella).— The larvie 

 of this small moth is responsible for doing a great deal of 

 injury to the t-^hoots of raspberry canes in some districts. 

 The moth itself appears at the end of May and in June, 

 and lays its eggs upon the flowers of the raspberry. In 

 about a week's time caterpillars are hatched, about one- 

 quarter of an inch long, and of a pinkish or reddish colour 

 with a black head. The caterpillar soon leaves its floral 

 nest by crawling or letting itself down by silken cords to 

 the earth beneath the canes, and hibernates in a silken 

 cocoon during the winter. Early in April the larva leaves 

 the cocoon, crawls up the canes to the nearest bud, gnaws 

 its way through this into the pith of the cane, and then 

 starts to feed voraciously upon it. In consequence of 

 this attack the canes refuse to put forth healthy leaves 

 or to bear fruit, and speedily wither and die. 



Remedies. — As the caterpillars hibernate in the soil 

 around the base of the raspberry canes, the soil should 

 be dressed with soot or lime in early winter and then
