| 中文摘要: |
| 研究结果表明:轮纹异痂蝗在通辽1年发生1代,以卵在土中越冬。越冬卵于翌年5月上中旬孵化,蝗蝻共4龄,全蝻期26～32 d,6月上、中旬为羽化盛期。7月上、中旬为产卵盛期,卵产在土中深4～6 cm处。成虫可活到9月中旬。轮纹异痂蝗喜食菊科和百合科等幼嫩多汁的植物,食量为每头每日食鲜草1.05 g,每666.7 m2可损失鲜草10.25～12.75 kg。 |
| 英文摘要: |
| Bryodemella tuberculatum dilutum(Stoll.) had one generation per year in Tongliao Area.They laid eggs in the soil to over-winter.These eggs began to hatch in the first and middle ten days of May in the following year.Locusts had 4 instars and the nymph stage lasted for 26～32 days.Eclosion took place in the first twenty days of June,while oviposition occurred in the first twenty days of July.Their eggs were oviposited about 4～6 cm under the surface of the soil and the adult locusts could survive till the middle of September.Each locust that prefers juicy plant seedlings such as Composite & Liliaceae could eat 1.05 g fresh grasses per day,which means that 10.25～12.75 kg fresh grasses per 666.7 m2 may be lost. |
