PARKS: EXTENSION ENTOMOLOGY

collected in the immediate vicinity. To the exhibit was attached a 
card of information of what was known about the location of the egg- 
laying places in that community and directions for their destruction by 
cultivation. The same plan is being followed with respect to control 
work with chinch bugs. Attractive exhibit boxes are being placed 
only in ‘localities where the chinch bugs are again becoming abundant 
and promise to injure the crops in 1918. These show the tufts of sedge 
grass (Andropogon scoparius) which are the natural hibernating places 
for chinch bugs in Kansas, and the same after the back fire has burned 
it off and killed the bugs. Advance work with Hessian fly has given 
us knowledge which is of great value in carrying on extension work 
against this pest in 1918. For example our survey work has given 
us the exact localities of probable injury next year and has revealed 
the fact that only 50 to 60 per cent of the summer “ flaxseeds” present 
in old wheat stubble in the infested localities gave up adult flies last 
fall, and that we may expect the remainder to reinforce the army of 
spring brood of flies. 
We find that our project work must be outlined along the preven¬ 
tive course, and while these preventive measures are well known by 
us, they are either not known to, or the need for using them is not real¬ 
ized by, the busy farmers who often go blindly into the outbreak. One 
of the surprises of an entomologist entering upon extension work is to 
learn how little the average general farmer knows of injurious insects 
and their control, notwithstanding the volumes of literature that have 
been published, which may or may not have reached theJarmer, or if 
so, may or may not have been read by him. Such knowledge makes it 
imperative to an active field worker that different methods must be 
used to have results of entomological investigations put into operation 
on the farms. The average farmer is tired of reading advice given 
gratuitously and wants to see you on his farm and talk with you about 
his conditions. This makes it necessary that the worker in extension 
entomology must be qualified to speak intelligently along other lines of 
agriculture and should have farm experience and an agricultural edu¬ 
cation. If he can bud, graft or prune correctly or can bind a sheaf of 
wheat by hand, the farmers’ confidence is soon gained and the work of 
the entomologist made all the easier. Through your visit the farmer 
feels that he is in personal touch with the institution you represent, 
and the entomologist soon learns to know the methods that are practi¬ 
cal for the farmer to use under present conditions. Getting informa¬ 
tion both to and from the counties is best accomplished through co¬ 
operation with the county farm bureau agents who understand the 
needs of their communities, and who through their local leaders are 
able to bring about a better community cooperation among farmers.
