Study on the Feeding,Fecundity and Duration of Hylobitelus xiaoi Zhang Adult of Different Hosts

Effects of 8 plant species on the feeding,fecundity and duration of Hylobitelus xiaoi adults were evaluated at a constant temperature of 25 ℃ and relative humidities(RH) of 90%.Results showed that the adults consumed 83.9 mm2 of Pinus elliottii twigs which was significantly higher than they did on other plant species.Adults laid significantly more eggs and lived significantly longer on Pinus elliottii twigs than on the other plant species twigs.Feeding on Cunninghamia lanceolata、Podocarpus macrophyllus and Pseudolarix kaemoferi led to higher mortality of the adults.
