摘　　要：青脊竹蝗成虫喜于毛竹林缘杂草、杂竹较多、土壤疏松的阳坡地带交尾。然后选择附近杂草稀少的空地产卵,于土壤表面留下产卵孔。运用这一典型特征,能迅速找到卵块,缩短虫情调查时间。在实际调查中应用,效果良好,值得推广。卵块的调查时间应选择在11月中下旬。平均每个产卵孔下方有卵30粒。Most of the adults of Ceracris nigricornis Walker copulated at the sunny sloping fields of the bamboo （Phyllostachys heterocycla cv. pubescens） forest edge with much weed, sundry bamboo and loose soil. And then they oviposited in the soil of the clearing nearby, and left over an eyeable aperture on the surface. Thus, the ap- erture was favourable for discovering the ovum dollop of C. nigricornis in the pest population survey, and shortening survey time and improving survey efficiency. Moreover, the ovum dollop had better be surveyed in the last ten days of November. There were 30 eggs under the oviposition aperture on average.
