chrysanthemum aphid

The chrysanthemum aphid (Macrosiphoniella sanborni) is a soft-bodied insect in the family Aphididae, a specialist pest of cultivated and wild Chrysanthemum species and related members of the family Asteraceae. It is a dark brown to reddish-black aphid, distinguishing it from many green or pale aphids, and infests the shoots, leaves, and flower buds of its host plants. Like other aphids, Macrosiphoniella sanborni feeds by inserting its stylet mouthparts into plant tissue to extract phloem sap, depriving the host of carbohydrates and amino acids. Heavy infestations cause stunting, leaf curl, distortion, and reduction in flower quality and yield, making it a significant pest in the commercial chrysanthemum industry worldwide. The species can reproduce parthenogenetically — females producing live young without fertilization — and populations can build rapidly under warm greenhouse conditions. Chrysanthemum aphids excrete honeydew, which supports the growth of black sooty mold on plant surfaces, further reducing photosynthesis and ornamental value. They may also transmit plant viruses during feeding. Natural predators including ladybirds, lacewings, and parasitoid wasps provide biological control, though chemical aphicides are frequently used in commercial cultivation.
