WISCOHSIIT 
This is the fifth year in which collections have been made in 
typical environments in, Wisconsin during the adult survey. There were 
6,717 specimens taken in 8 representative' habitats, and 19 species are 
included in the collections, Melanoulus femur- ruh rum was by far the 
dominant species in all 8 habitats, ranging from 63 to 80 percent of the 
specimens collected in these places and forming 71 percent of the total 
specimens collected for the State, Melanonlus mexicanus was second in 
numbers in 7 out of the 8 environments, ranging from 3 to 14 percent of 
the numbers taken in these habitats and forming 7 percent of the total 
collected in the* State, This does not include the large number of 
nymphs found in the collections, which are probably M. femur- rub rum 
because that species hatches late in the season. Altogether, this places 
M, mexicanus lower in relative abundance and M, femur-rub rum higher, as 
compared with the -1938 collections. 
In 1939 cold, rains took care of most of the infesta-tions of 
M, mexicanus , which hatched early in the summer. In a few counties 
damage was done- to hay and other crops by M, femur- rub rum . Infestations 
were found in alfalfa, pastures, hay meadows, and some small-grain 
stubble.
