谷斑皮蠹幼虫在无任何食物和水供应的饥饿条件下，有互相残食行为；对同类的卵有取食的习性；对同类各虫态尸体有摄食现象。但取食量甚微，且都不可能是其延续生命的补充营养来源。主要依靠滞育幼虫的生理特征和自身体内营养物质的特殊低耗来维持生命。饥饿１８０天的幼虫恢复取食后生长发育正常，对以后成虫的生殖力无明显影响。饥饿３６５天后恢复取食的幼虫，化蛹率明显降低；少数幼虫能化蛹并羽化发育正常的成虫；多数幼虫不能化蛹或化蛹不能羽化而死亡 Guppy moth larvae in the absence of any food and water supply conditions of hunger, there are mutual residual feeding behavior; habit of feeding on the same species of eggs; However, the amount of food intake is minimal, and none of them can be a source of supplemental nutrition for the continuation of their lives. Mainly rely on the physiological characteristics of diapause larvae and their own low consumption of nutrients in particular to sustain life. The 180-day-old larvae returned to normal growth and development after feeding, and had no significant effect on their fecundity. After 365 days of starvation, feeding larvae were recovered, the pupation rate was significantly reduced; a few larvae could pupate and develop normal adults; most larvae could not pupate or pupate could not emerge and die
