Preliminary Study on Experiment of Innocuous High Fat Film Control Carposina Niponensis Walsingham

Spraying innocuous high fat film on the ground of apple orchard to control Carposina nipo-nensis Walsingham in Weibei dry land, the result showed that it could change the small climate of the insects surroundings, destroy normal grow rhythm of the insect.
