the last application be omitted, but that the first and second appli- 
cations be made very thorough. 
It is realized that the control recommendations given for this insect 
are not altogether satisfactory, but in the light of present knowledge 
they are the best that can be offered. Further detailed investiga- 
tions are now being made to determine, if possible, a more effective 
method of controlling the pecan nut case-bearer, as well as other 
pecan insects of economic importance. Some time must necessarily 
elapse before reporting on these investigations, and in the meanwhile 
pecan growers are urged to use the control measures recommended.
