| Abstract: | Through fixed observation,ecological characteristics of Rhynchaenus empopulifolis Chen were studied.Result shows that:the egg hatching rate,larvae survival & emergence rate of Rhynchaenus empopulifolis whose sex ratio is 1:1 is 82.1%,93.1%,53.3%,respectively;the development threshold temperature(DTT) and effective accumulated temperature(EAT) during egg stage is 11.65℃±0.18℃,8.27±1.28 degree day,respectively.The DTT and EAT during larval stage is 14.53±0.45℃,31.54±7.16 degree day respectively.The DTT and EAT during prepupa-pupal stage is 16.80±0.31℃,24.76±3.41 degree day. |
