摘要
越北腹露蝗是广东北部地区的重要害虫。根据越北腹露蝗卵巢发育形态特征的变化,可分为Ⅰ级(透明期),Ⅱ级(卵黄沉淀期),Ⅲ级(卵粒形成期,侧输卵管膨大为卵巢萼),Ⅳ级(成熟待产期,卵储存于卵巢萼),Ⅴ级(产卵期)共5个级别。研究结果可应用于该蝗虫产卵期的预测预报。
Fruhstorferiola tonkinensis was an important insect pest in Northern Guangdong province. Ovarian development could be classified as 5 grades according to ovarian morphological characteristics,grade one (clear period),grade two (yolk deposition period),grade three (egg forming period,lateral oviducts swell and form calyxes in the period),grade four (egg maturing period),and grade five (oviposition period). Grading results could be applied in forecasting the occurrence of Fruhstorferiola tonkinensis.
