中南林業(yè)科技大學(xué)生命科學(xué)技術(shù)學(xué)院昆蟲行為與進(jìn)化生態(tài)學(xué)實驗室肖全紅教授團(tuán)隊于2026年3月在Journal of Insect Physiology雜志發(fā)表“Metabolic depression drives discontinuous gas exchange in diapause pupae of Sericinus montelus (Lepidoptera: Papilionidae): a seasonal adaptation strategy”研究成果,文中實驗以絲帶鳳蝶(Sericinus montelus Gray)為模型,通過比較不同光照周期和溫度條件下蛹的氣體交換模式及代謝特性,探討了滯育和溫度對呼吸模式的調(diào)控作用。結(jié)果表明,滯育期的蛹的代謝率顯著低于非滯育期蛹,并且它們穩(wěn)定地維持著間歇性氣體交換(DGE)模式。相比之下,所有非滯育期個體都表現(xiàn)出連續(xù)性氣體交換。溫度通過調(diào)節(jié)代謝率影響呼吸模式:滯育期蛹在整個測試溫度范圍內(nèi)均保持DGE模式,而非滯育期蛹在低溫下仍為DGE模式,但在高溫下轉(zhuǎn)變?yōu)檫B續(xù)性氣體交換,這表明存在一個觸發(fā)轉(zhuǎn)變的代謝率閾值。此外,DGE周期參數(shù)同時受到溫度和滯育期的影響:低溫和滯育期的延長顯著延長了間歇期和總DGE周期長度,而每次氣體交換釋放的CO2體積保持穩(wěn)定,這與DGE的濕氣假說一致。

研究指出,光照周期引起的代謝抑制是絲帶鳳蝶滯育期蛹DGE模式的核心驅(qū)動因素,而溫度則通過影響代謝率來微調(diào)周期參數(shù)。這些機(jī)制共同優(yōu)化了能量保存并可能減少水分損失,突顯出這種生理適應(yīng)在不同昆蟲類群中的差異性。
