be very abundant upon crimson clover throughout the State. In 
several instances they were observed spreading to the peas. With 
rare exceptions, however, they spread only to the late peas, and almost 
all our growers had first-class crops of early peas. One or two fields 
of crimson clover immediately next to pea fields were fairly alive with 
lice, and though none could be found on the early peas they were 
spreading on to the late varieties. At this time but few lice could be 
found on red clover. By May 22 the lice had become quite thick on 
the late peas. Fields sowed in 8-inch drills were found to be much 
worse infested than those in 30-inch rows, and subsequently were much 
worse injured. In fact, both early and late peas sown in drills or 
’ broadcast were a practical failure. One acre of market garden I saw 
had hardly a pod formed; on another field of 20 acres of Alaska and 
Admiral about 1,000 pounds of peas were secured and the rest was cut 
for fodder or turned under. By this time (May 22) most of the clover 
had been turned under, and the lice had left that which remained 
‘standing. They now became more common on red clover throughout 
the State, but never very numerous. In fact, pea lice could now be 
found everywhere and on everything. On squash vines, apple trees, 
in every fence-corner cobweb, could be found the ever-present, stray 
pea louse. 
Not until the first week in June did the enemies of the lice commence 
to check their increase, and though they soon multiplied so rapidly, 
and did such efficient service, that but few lice were to be found when 
the late crop was being cut on June 18, still they were too late to 
benefit the pea crop, as the injury had already been done. Asa result 
the late varieties have probably yielded about one-fourth of a crop on 
the average, the yield varying from absolutely nothing to a full crop. 
The lice have been fewer in numbers and have done less injury than 
last year, as last year considerable injury was done the early crop. 
Had it not been for the cool, wet weather of the latter part of May, 
the injury would have been much more severe, but this doubtless 
prevented a more rapid reproduction of the aphides. 
Possibly the most important enemy of the lice was the fungus 
Limpusa aphidis. Individuals killed by this were found commonly on 
clover early in the season, but not in any number. Not until June 11 
were diseased lice found in quantity, but on that date it was apparent 
that the fungus would soon kill the larger part of them, as many were 
dead and the majority were affected. A week later but very few lice 
were found, and almost all were diseased. 
Parasitized aphides were fairly common on the crimson cloyer, but 
none were seen on peas until June 11. Atleast 5 per cent were killed 
by parasites whose identity has not yet been determined. Last fall 
several Aphidius washingtonensis Ashm. were bred.
