rose aphid
Quick Summary
The rose aphid (Macrosiphum rosae) is a type of plant louse that feeds on rose plants, particularly new shoots and buds. As part of the larger aphid family (Aphididae), these small, soft-bodied insects are known for being serious plant pests. They can stunt plant growth, cause deformities in leaves, buds, and flowers, and transmit plant virus diseases.12
Aphids reproduce through parthenogenesis, where wingless females produce live young without fertilization. When populations become crowded, winged adults develop and fly to new plants. In cooler climates, they lay eggs that survive the winter, while in warmer regions, reproduction can be continuous. Natural predators like ladybird beetles and lacewings help control aphid populations.2
