摘要
本文初步研究了老熟和预蛹阶段的黑水虻Hermetiaillucens对于酒精毒性、氧胁迫和高渗透压条件下的耐受特性,结果显示黑水虻幼虫和预蛹在三种胁迫因子处于20%～60%(浓度)的较低水平时,其平均死亡率低于20%,表现出良好的抗逆性。高浓度的酒精、矿物油和氯化钠溶液对于黑水虻的生存都会产生负面影响,但是幼虫与预蛹由于其生理形态上的变化,致使其在抗逆性方面表现出显著差异,预蛹阶段的黑水虻对矿物油较为敏感,而幼虫则对高盐环境的耐受性表现较弱。
The stress tolerance of black soldier fly,Hermetia illucens,larvae and pre-pupa in solution of alcohol,mineral oil and common salt with gradient concentration was studied.The result indicated that it showed positive performance for black soldier fly larva and pre-pupa when stress factors were lower level,but it with high level obviously were going to hurt insect body and increase mortality.The more attention should been paid on the difference between larvae and pre-pupa on stress resistance in mineral oil and common salt.It implied that pre-pupa of black soldier fly were more susceptive to mineral oil than larvae and larva were less tolerated to common salt instead,which might be the result from physiological and morphological deviation of insect cuticulae.
