Studies on the Sampling Efficiency by Traditional and Motor-Sucking Methods for Insect Collection in Field Condition

Dongfanghong-18 motor-driven sprayer has been re-designed for both insect-sampling and spraying usages.A serial of test with different sampling methods had been carried on to compare the sampling efficiency, the range of sampled insects, the accuracy for estimating the population density and spatial distribution of planthoppers.The results indicated that the efficiency of motor-sucking sampler was 91.58%, the highest one among five methods.
