Effects of three host plants on the growth,development,reproduction and longevity of Leiometopon simyrides(Lepidoptera:Noctuidae)
Leiometopon simyrides is an important leaf-feeding pest insect of Nitraria spp.To explore the influence of host plants on the growth and development of L.simyrides and provide a foundation for monitoring and controlling this pest,Nitraria roborowskii,N.sphaerocarpa and N.tangutorum were used to raise L.simyrides at constant temperature 27℃,and the biological characteristics of L.simyrides,such as the developmental duration,survival rate at various developmental stages,emergence rate,sex ratio and longevity of adult were observed and recorded.At the same time,the contents of nutrient and secondary metabolites in the leaves of three host plants were measured.The results showed that the total leaf consumption was the least when L.simyrides fed with N.roborowskii,and the most on N.tangutorum.The developmental duration of L.simyrides was the shortest when fed with N.tangutorum,followed by those fed with N.sphaerocarpa,and the developmental duration was the longest when fed with N.roborowskii.The survival rate of larvae and emergence rate of L.simyrides were higher when fed with N.sphaerocarpa and N.tangutorum.The survival rate of larvae was the lowest without adult emergence when fed with N.roborowskii.The female adult proportion of L.simyrides was the highest when larvae were fed with N.tangutorum,while the adult longevity was the longest.The contents of total phenol and simple phenol in N.roborowskii leaves were the highest,and the lowest in N.tangutorum.The content of nutrients in N.roborowskii leaves was the lowest,but higher in N.tangutorum and N.sphaerocarpa.N.tangutorum and N.sphaerocarpa were suitable for the growth,development and reproduction of L.simyrides.N.tangutorum was the optimum plant for L.simyrides,followed by N.sphaerocarpa.
