Aphis rubicola

Oestlund, 1887

Aphis rubicola is a of in the Aphididae, described by Oestlund in 1887. The species exhibits with seasonal , producing sexual morphs (males and oviparae) in response to short-day . Laboratory studies demonstrate that temperature significantly modifies sexual morph production, with lower temperatures enhancing the transition to . The specific epithet suggests association with Rubus (raspberry/blackberry) as a plant, though this has not been explicitly confirmed in available sources.

Life Cycle

Holocyclic with seasonal . Under short-day conditions, produces sexual morphs (oviparae and males). Temperature modifies the reproductive transition: at 19.4°C, more than 95% of progeny are sexuals, compared to approximately 58% at 25.1°C. A 2-day cessation of precedes male production at 19.4°C but not at higher temperatures. Higher temperatures result in earlier deposition of most progeny, an earlier and more extended period of male production, and a lower ovipara:male ratio.

Behavior

Exhibits temperature-dependent in sexual morph production. Short-day serves as the primary cue for sexual induction, with temperature acting as a significant modifying factor.
