Dendrolimus punctatus(Walker)is a main pest to Pinus tree in Hubei eastern region.

Applied lightplane,the examination by large area of ultra-low volum spraying abameatin controlling larva of Dendrolimus punctatus(Walker) showed that,the control efficacy was over 95%,and abamection could control D.

At the same time, it reduced the quantity of pine caterpillar and kept the stabilization of .

Based on the spatial temporal characteristics of interaction of pine caterpillar larvae population,a three dimensional correlogram and spatially mixture regression model was proposed.

5% EC deltamethrin was diluted with 0 # Diesel oil and sprayed at 30 and 40 mL·hm -2 during an aerial spraying,the average mortality rates of pine caterpillar were 96.
