【摘要】：大猿葉蟲Colaphellus bowringi Blay是一種重要的十字花科蔬菜害蟲,以成蟲越冬和越夏。明確大猿葉蟲非滯育品系生殖力下降的現(xiàn)象是否與交配行為的改變相關(guān),將促進該非滯育品系在滯育遺傳、滯育調(diào)控分子機制研究中的應(yīng)用。本研究在25℃和L∶D=12∶12 h條件下,測定了大猿葉蟲滯育品系和非滯育品系的交配節(jié)律、交配持續(xù)時間和交配頻次。結(jié)果表明,大猿葉蟲滯育品系和非滯育品系交配高峰均出現(xiàn)在光期開始后2 h,非滯育品系的交配比率顯著低于滯育品系。滯育品系和非滯育品系第1次交配持續(xù)時間無顯著差異,分別為122.7±7.4 min和100.1±10.2 min;但非滯育品系的總交配持續(xù)時間顯著低于滯育品系。非滯育品系的交配頻次為2.2±0.3次,顯著低于滯育品系的3.8±0.5次。滯育品系和非滯育品系交配行為的比較發(fā)現(xiàn),大猿葉蟲非滯育品系生殖力降低與其交配比率下降、交配持續(xù)時間縮短和交配頻次減少顯著相關(guān),本研究為進一步利用非滯育品系為材料解析滯育遺傳、滯育調(diào)控機制奠定了基礎(chǔ)。
[Abstract]:Colaphellus bowringi Blay is an important vegetable pest of Cruciferae, which overwinters and summer as adults. It is clear whether the decline in fecundity of non-diapause strains is related to the change of mating behavior. This study will promote the application of this non-diapause strain in the study of diapause heredity and diapause regulation molecular mechanism. The mating rhythm of diapause strain and non-diapause strain was determined at 25 鈩，
