performed outside of this area except to the South, so it is impossible 
to state just how widely the insect may be distributed. It is planned to 
carry on additional scovting by both plant board and Bureau men on the 
appearance of a new generation when the beetles become more abundant. .As 
the insect feeds normally at night ani hides in the daytime, it is very 
difficult to scout for it unless the adults are very common. 
Plant deliveries for sweet-potato weevil eradication are progress-
