Evidence for selective disadvantages of large body size remains scarce in general. Previous studies the yellow dung fly Scathophaga stercoraria have demonstrated strong positive sexual and fecundity selection on male female size. Nevertheless, flies from a Swiss study population has declined by ~10% 1993–2009. Given substantial heritability size, this negative evolutionary response an evidently...

Entomopathogenic nematodes such as Steinernema and Heterorhabditis spp. and their associated symbionts are virulent for fly larvae in certain substra...
