The results of these completed experiments of the »resent season 
agree with those of last season excenvt in the amount by which the tol- 
erance was exceeded. The residues on cabbaye of the 1933-34 season 
exceeded by several times that »rasent on any preceding experiment. 
This difference was evidently due to rainfall. Only 2.28 inches of 
rainfall occurred during the course vf the 1953-34 tests, as com- 
pared to aprange in precipitation cf from 7.66 to 11.32 inches dur- 
ing the ,eriods »receding residue experiments. 
Conditions favor pea weevil infestation in Idaho.--According to 
T. A. Brindley, Moscow, Idaho, prospects are favorable for a decided 
increase in pea weevil damage this coming season. If the weather 
continues mild the only redeeming feature of the situation will be 
the small hibernating population. An interesting result of the con- 
tinued mild weather is the survival of volunteer peas in the winter 
wheat. Last fail during the harvest sezson unusual quantities of 
peas were shattered because cf climutic conditions. Whole fields 
seeded to winter wheat resembled sea fields, so great was the quan- 
tity shattered. Favorable climatic conditions allowed practically 
all of these eas to germinate and, thus far, all of these peas have 
survived. It is possible, should ie warm weather continue, that 
these »eas will survive and absoro some wf the weevil damage. This 
would alleviate the situatiun this cro» season, but would breed large 
pea,weevil. populaticns for 1935. 
Sperm found in male click beetle after mating.--As a part of the 
study of the question cf whether a male click beetle can mate more 
than once, an investigation conducted by C. E. Woodworth, of the 
Walla Walla, Wash., laboratory, develo»s that after mating many sperm 
were left in the male. These were found in the lateral horns of the 
seminal vesicle and in the testes. Eggs have been obtained after the 
first mating in both Limonius canus Lec. and L. californicus Mann., 
and observations as to fertility are being made. The economic value 
of this study is to determine the importance of collecting male bee- 
ties at the time of the flight. 
Importation of Europvean earwig parasites.--S. E. Crumb, of the 
Puyallup, Wash., laboratory, has submitted a revort on the importa- 
tion, biology, and rearing technique «of the European earwig parasite 
Digonichaeta setipennis Fall. during the period 1931-1933. The dates 
of collection, places of origin, number uf earwigs, and percentage of 
parasitization for each shipment are shown in the following tabulation:
