REPORT OF ENTOMOLOGIST. 
5 
from native plants for the College and Station collections. Mr. C. 
R. Jones, a special student in entomology here, found this bug 
common above timberline at Silverton, Colo., the past summer 
where he was collecting. Specimens are seldom taken at Fort 
Collins. 
The insect is single brooded. 
There was a great advantage this-year in having grain ripen 
early. Fall wheat escaped the injuries almost entirely. 
GRASSHOPPERS. 
The destructive grasshoppers (locusts) which are usually very 
numerous over a great portion of the agricultural section of the 
State were comparatively few in number this year except in limited 
sections. The previous year was marked by unusually severe 
grasshopper depredations and the small number of these insects the 
present year is probably due to the prevalence last year of the na¬ 
tive grasshopper disease, Empusa grylli On the other hand, 
there has been very little of this disease among the grashoppers 
the past summer and fall. 
The Australian Grasshopper Fungus , was experimented 
with again this year. Several tubes of the fungus were sent di¬ 
rectly from the Colonial Bacteriological Institute of the Cape of 
Good Hope through the kindness of the director, Dr. Alexander 
Edington. The cultures were received in an excellent condition 
and were used in the field and in our breeding cages but in no case 
were we successful in killing any of the grasshoppers as far as we 
could determine. As this is the second year that we have worked 
with this disease without obtaining any apparent results, I can see 
no reason to encourage Colorado farmers to hope for relief from 
grashopper depredations through the use of the x-lfrican grasshop¬ 
per fungus (Mucor sp.) 
A new grasshopper remedy known as u Criddle mixture” has 
been reported very efficient for the destruction of grasshoppers in 
Manitoba. It consists of a mixture of fresh horse manure, salt 
and Paris green which is distributed about the fields where the 
grasshoppers are numerous. In our experiments the ingredients 
were used in the following proportions: 
Fresh horse manure.40 quarts. 
Barrel salt.2 quarts. 
Paris green.1 quart. 
The preparation was repeatedly used in breeding cages and 
in field tests. In no case were the results very encouraging so long 
as there was green food obtainable. Poisoned alfalfa leaves and 
poisoned bran were used in comparison with the Criddle mixture 
and of the three the bran seemed most efficient. None of these 
preparations gave results that were very satisfactory.
