The results showed that the developmental duration and survivor rate of E. onukii from egg to adult was 18.50 d and 46.85%, respectively, which had no significant difference from the negative control. The adult capture would decrease when the lamp height and distance increased. As the lamp height was within 20-40 cm, the mean effective insect-killing distance, median trapping distance, and golden trapping distance were 58.17, 30.41, and 23.86 m, respectively. In the field, the adult population of E. onukii in 5 m lamp distance first reached the maximum compared with those in other lamp distances. The adult populations in different lamp distances showed significant differences with the passage of time. During the population peaks, the adult population within 25 m lamp distance was only 49.5%-64.4% of that in 120 m lamp distance, which indicated that the light-emitting diode light trap equipped with the suction fan could significantly reduce the population of E. onukii within golden trapping distance by adult trapping. keywords:Empoasca onukii  LED light trap  suction fan equipment  capable insect-killing distance  population dynamic View Full Text  View/Add Comment  Download reader
