Other Nitidulidae. The buried trap took beetles beginning December 24 
and captured a total of 111 Carpophilus hemipterus, 26 adult nitidulids 
of other species, and 15 nitidulid larvae. The weak powers of locomo-— 
tion to be expected during the winter months are illustrated, as 7 times 
as many adult Nitidulidae entered the easily accessible buried trap as 
were taken in the adjacent trap, of which the entrance was 12 inches 
above the surface." 
Bean weevil infestation gains.--C. K. Fisher, Modesto, Calif., re—- 
ports that in a total of 2,246 warehouse bean samples examined in 1932 
1,685, or 75.02 percent, showed infestation (by Acanthoscelides obtectus 
Say). "A total of 1,952 samples of blackeye cowpeas were examined, of 
which 1,591, or 81.5 percent, showed infestation. Compared with the 1931 
season, this is an increase of 9.24 percent. * * * Infestations in the 
following varieties showed increases over the 1931 season: Limas, reds, 
small whites, cranberries, and bayos. Pinks showed a small decrease. The 
increase in weevil infestation during the past two seasons is explained 
by low prices and poor market conditions. Market conditions have caused 
many ranchers to store their beans on the ranches rather than in public 
warehouses. Many of these beans stored on the ranches have become sources 
of infestation for the growing crop." 
Idaho, reports that in an experiment "to determine the effect of the 
time of burying on the emergence of Bruchus pisorum L., 50 pods were 
buried at similar depths at the same time and an equal number of each was 
placed on top of the ground as a check. * * * Very few of the weevils 
emerge when the peas are buried at a depth of 34 inches if the emergence 
Hole in the pea has not been opened before the peas are buried. * * * 
Previous experiments had shown that burying weevilly peas would prevent 
the emergence of the adults when carried on in small cages, so this 
experiment was designed to test it on a larger scale, with farm imple- 
ments. Such an experiment is necessary in order to control the weevils 
in shattered peas. The peas were buried immediately after the first 
harvesting. * * * 15,000 weevilly peas were spread out evenly on each of 
three 6—-foot-square plots. One of these plots was plowed under by a 
caterpillar tractor, another was disked under, and a third was left as a 
check. Two plots of vines, just as they grew in the field, were also 
treated. * * * On the check plot 69.07 percent of the weevils emer- 
ged, 13.82 percent from the disked plot, and 2.63 percent from the plot 
that was plowed under. * * * it is evident, during this season, that 
plowing under the shattered peas immediately after early harvesting 
killed most of the weevils in the shattered peas. * * * Shelled peas 
and also peas in pods were spread on the surface of the ground at weekly 
intervals. The temperature at the surface of the ground was taken each 
may. at: 1 p.m. The maximum temperature obtained was 133.8° F. * * * 
It is evident that the greatest mortality occurs when the weevils are in 
the larval stage and that a greater number die in the shelled peas than 
in the peas in the pods.”
