CURRANT APHIDES. 



{lilutpiikmphuiii rihis, Linn., and I\f//ziis ribis, Linn.) 



All three varieties of currants are often attacked by Aphides 

 or Plant Lice. At least two species are culprits. 



During 1901 currant buslies were considerably damaged by 



them. In some districts the 

 1 )ushes were quite ruined, the 

 leaves turned brown and 

 shrivelled up, and the fruit 

 fell off, the bunches " shank- 

 ing " in consequence of the 

 abnormal presence of these 

 ])ests. The rapid increase of 

 the " riant Lice " was due to 

 a long spell of dry, warm 

 weather, so flivourable to tlie 

 development of these insects, 

 so detrimental to the develop- 

 ment of the fruit and health 

 of the bushes. Aphides are 

 usually more or less preva- 

 lent on currants, and are 

 always liable under certain

The two currant species mentioned work in a slightly different 

 way. One, li. rihis, was at one time thought to produce reddish, 

 reddish-brown, or yellow blister-like galls on the surface of the leaves, 

 whilst Myzus rihis often causes the leaves to curl up, especially on 

 the top shoots. Both species are equally difficult to destroy after
