Entomological Work in Ohio.

FORECAST. 
The outlook for Entomological work may be considered as 
never more favorable and the opportunities in this line are strik¬ 
ingly shown in comparison with conditions a quarter century or 
more ago. My own recollection covers the development of 
practically all the methods of insect control, dependent upon the 
arsenical poison methods and fumigation, of quarantine, inspec¬ 
tion and largely those measures which are connected with the rota¬ 
tion of crops based upon certain definite conditions in develop¬ 
ment or habit which make such control possible. 
Looking ahead it may be pretty confidently predicted that 
Entomological Science especially that part which is particularly 
concerned in the control of injurious insects must undergo a great 
development and that the recognition of Entomological work 
must increase from year to year. 
Along the lines of development which seem now to be especially 
promising are those based on studies of insect ecology, insect 
reactions and migration. While the use of arsenical poisons has 
reached a high degree of perfection it seems that these should be 
considered rather as temporary measures and that just as rapidly 
as possibly they should be replaced by control measures which do 
not necessitate the use of compounds which present such a degree 
of danger in their common use. The possibilities in the develop¬ 
ment of control measures based upon the use of repellants, or 
baits seem to deserve most careful investigation. This appears 
to me to be one of the fields in which there is opportunity for 
most valuable research. 
The introduction of insect diseases and insect parasites is 
another phase which deserves continued investigation. While 
for some of the forms already tested the results have been dis¬ 
couraging, advantage has been shown in a sufficient number of 
cases to indicate that further study is needed for the determination 
of those fungi and bacteria which may be amenable to artificial 
control and especially the continued experiments with the trans¬ 
portation or introduction of parasitic insects for the checking of 
species not otherwise readily controlled. Along the line of adjust¬ 
ment of farm and orchard methods there is a large opportunity for 
more precise determination of the dependence of insects upon cer¬ 
tain crop conditions and the adjustment of cultural methods to 
circumvent insect injury. 
Especially along the line of exclusion of menacing insects of 
other countries there is opportunity for most careful study, a 
study which should cover the destructive insects of other portions 
of our own domain, also of adjacent countries and even those 
which are so remote as to offer litle direct opportunity for migra-
