Development, Host Choice of Mythimna separata and Its Relationship with Biochemical Compounds of Different Maize Varieties
摘要
Abstract
In order to clarify relationship between development, host choice of the oriental aryworm, Mythimna separata and content of biochemical substances in different maize varieties, the development duration, feeding and reproduction choice of this pest on 22 maize varieties was observed under the libaratory conditions of 25±1 ℃, 70％-80％ RH and a photoperiod of 14 L∶10 D, and content of four biochemical substances in 22 maize varieties were also investigated.The results showed that the M.separata exhibited significant difference in the development andpupa mass among tested corn varieties, but the eclosion rate had no difference.The development duration of larval+pupa was the shotest on Qiandan 16 variety (26.14 d), and the longest on 8017 variety (29.36 d).The heaviest pupa mass was observed on Andan 3 variety (346.84 mg) and the lightest was observed on 7079 variety (298.71 mg).The highest surval rate was found on Qiandan 16 variety (93.33％), while the lowest was found on 8021 variety (66.87％).The M.separata had obvious feeding and reproduction choice on different corn varieties, and this pest profered to reproduction (5.67 mass per plant) and feeding (9.00 pest per plant) on Qiandan 16 variety.Content of total phenols, flavonoids and total protein were significantly different among maize varieties, but the content of total sμgar was not different.Correlation analysis showed that content of these substances were not associated with development of M.separata.Development, survial and host choice of M.separata are obviously different among 22 maize varieties, which are not associated with the content of 4 tested biochemical substances.关键词
