鲁北中华剑角蝗生物学特性初步观察

Preliminary observation of the biological characteristics of Acrida cinerea

中华剑角蝗(Acrida cinereaThunb.)是鲁北地区的优势蝗种,为明确中华剑角蝗的发生规律,于2004—2007年通过大田调查与笼内饲养相结合的方法进行了调查研究。结果表明:中华剑角蝗在鲁北地区1年发生1代,以卵在土中越冬,蝗蝻6龄。并对中华剑角蝗的年生活史、历期、生活习性、发生影响因素进行了详述。

Acrida cinerea Thunb is the dominant species in northern Shandong. The occurrence of A. cinerea was investigated by combining field observations with feeding tests in cages in 2004--2007. The results indicated that A. cinerea occurred one generation a year, overwintered in the soil by spawns, and experienced 6 instar before becoming adult. Its life history, life habits and influencing factors was also described.
