Immune stimulation has no effect on lifespan in T. molitor (∼2% variance explained).
“survival under food limitation was only weakly affected by immune treatment (∼2% variance explained)”

Immune stimulation increases metabolic rate in T. molitor (explaining approximately 30% of the variance).
“Immune stimulation elevated metabolic rate, with treatment explaining approximately 30% of the variance in log-transformed metabolic responses”

Macronutrient balance dictates lifespan and reproduction in a beetle, Tenebrio molitor
The Journal of experimental biology3 Jun 2025
Protein-to-carbohydrate ratio improves egg production in T. molitor (P:C 1.31:1).
“Female reproductive traits peaked at higher P:C ratios (reproductive lifespan 1:1.06; lifetime egg production 1.31:1; egg production rate 1.75:1)”

Hymenolepis diminuta infection extends lifespan in T. molitor (HR 2.35 (control vs infected), p < 0.001).
“an overall very highly significant difference in survival time (p < 0.001) between infected and control populations of beetles, with a hazard ratio of 2.35 (control versus infected)”
