STRAWBERRIES 47 
infested with green fly or red spider, unless preventive 
measures are adopted, and it is always well to bear in 
mind that these need be only the light application of 
fumigation or vapourisation, or weak insecticides, to 
keep down the pests, whereas if insects are allowed 
to increase and remedies have to be applied, these must 
needs be strong to effect a clearance and in that 
condition frequently check the plants and reduce the 
quantity and quality of the crop. 
The following are the principal strawberry pests. 
Cuckoo Spit (Aphrophora spumaria).—This little pest 
is sometimes a great nuisance, settling on young leaves 
and expanding flower trusses, and exuding a frothy 
matter that has the appearance of spittle. The insect 
hops briskly when clear of the moisture. But hand 
crushing is a good way of reducing an infestation. 
Another method is to syringe the crop with a warm 
tobacco solution, following this shortly after with clear 
water. 
EELworM (Aphelenchus fragaria). — Fortunately this 
is not a common enemy of the strawberry, for it is 
not an easy one to combat. It is a member of the group 
of Stem Eelworms, and when it attacks plants it entirely 
alters the appearance of the flower-spike, making 
this, in the case of the strawberry, assume an appearance 
that suggested to Miss Ormerod the name of ‘ Cauli- 
flower Disease” for the infestation. Raw animal manures 
in quantity seem to induce eelworm, and as an alternative 
a good dressing composed of four parts phosphates, 
three parts sulphate of ammonia and two parts Wp nese 
of potash is recommended. 
GreEN Friy.—It is seldom that Green Fly (pis) 
does any harm to outdoor strawberry crops, but during 
the process of forcing it is almost sure to put in an 
appearance when the newleavesarise and the flower-spikes 
are pushing from the crown. This being so it follows that
