Insect Pests. 



Tlif pests appear to swarm at times 

 and leave the soil in luimljers. 



Small galled ami split growths ma}- be 

 seen where tlie a[)hides have taken up 

 their aliode near the stem, and in young 

 stdck tlie plants die under the attack. 



Should any pale wool and powder be 

 seen on young ciirraut stocks it is well 

 to have them cleaned before planting, liy 

 either wasln'ng them in warm soft soap 

 and water, toljacco w'asli, or fumigating 

 them "N^'ith hj'drocyanic acid gas. Injec- 

 tions of bisulphide of carbon also do 

 good. 



This apliis was sent me from Paddock 

 Wood in 18!J4, where it was found living 

 in the ground and was taken to be the 

 subterranean form of the Woolly Apliis (3). 

 It is to be found attached to the roots 

 and also in eartli chambers lined \\ith 

 cottony fibres. Buckton (5) described it 

 as a new species from Hasleniere. 



This insect has now been shown to be 

 the migrant form of ,ScJi i-.uin'iirn ulini (7), 

 which causes the curled leaves on the 

 elm in spring and summer, and when 

 these get tough it descends to the roots nf currants and gooseberries.
