Apple-sawfly

Guides

• Aptesis nigrocincta

  Aptesis nigrocincta is a bivoltine solitary ectoparasitoid wasp that attacks cocoons of the apple sawfly (Hoplocampa testudinea). Females are nearly wingless and significantly smaller than males, an adaptation for searching soil at 10–25 cm depth. The species is considered the most important mortality factor for apple sawfly cocoons in the studied orchard, achieving parasitism rates of 12.1–39.7% per generation.
