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.

Coast Myall

Coast myall (Acacia binervia) is a small to medium tree or tall shrub in the family Fabaceae, native to coastal and near-coastal regions of New South Wales and Queensland in eastern Australia. It grows in coastal heath, dry sclerophyll woodland, and scrubby vegetation on sandy or rocky substrates, often in association with banksias and eucalypts. Like most Australian wattles, coast myall produces phyllodes—flattened leaf-stalks functioning as leaves—rather than true compound leaves in mature plants. The dark green phyllodes are distinctive, with two main veins, giving rise to the species name binervia. Golden-yellow, spherical flower heads are produced in winter to spring, attracting native bees. The genus Acacia sensu lato encompasses hundreds of species across Australia and globally, many of which play important ecological roles in nitrogen cycling through root symbioses. Coast myall is assessed as Least Concern by the IUCN. It is sometimes planted in coastal revegetation projects for its tolerance of poor, sandy soils, drought, and salt-laden winds.
