Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been
