Several other monophagous scale insects, especially those on islands, are threatened by coextinction due to threats faced by their host plants. [10] Most scale insects are herbivores, feeding on phloem sap drawn directly from the plant's vascular system, but a few species feed on fungal mats and fungi, such as some species in the genus ...
Monophlebidae is a family of scale insects commonly known as the giant scales or monophlebids. They occur in most parts of the world but more genera are found in the tropics than elsewhere. [2] The cottony cushion scale, Icerya purchasi, is a serious commercial pest on many families of woody plants, including Citrus. It has spread worldwide ...
Icerya purchasi (common name: cottony cushion scale) is a scale insect that feeds on more than 80 families of woody plants, [1] most notably on Citrus and Pittosporum. Originally described in 1878 from specimens collected in New Zealand as pests of kangaroo acacia and named by W.M. Maskell "after the Rev. Dr. Purchas who, [he] believe[d], first ...
Bed Bug Bites. What they look like: Often confused with mosquito bites, bed bug bites are small, red, puffy bumps that appear in lines or clusters, usually three or more. They can have distinct ...
What they look like: Chiggers, a type of small mite, typically leave clusters of bites that are often very itchy. In many cases, chigger bites appear as small, red and itchy bumps. Sometimes, they ...
Fiorinia theae is a polyphagous scale insect of woody plants, infesting the underside of the leaves. Apart from tea plants in Asia, ornamental Camellia and Ilex species are the main hosts. Many other plants are infested less regularly. [5] ScaleNet lists more than 20 genera from 18 plant families as hosts, including various crops and ornamental ...
Cochineal insects are soft-bodied, flat, oval-shaped scale insects. The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. They penetrate the cactus with their beak-like mouthparts and feed on its juices, remaining immobile unless alarmed. After mating, the fertilised female increases in size and gives birth to tiny nymphs ...
The true bugs, Hemiptera, have piercing and sucking mouthparts and live by sucking sap from plants. These include aphids, whiteflies and scale insects. Apart from weakening the plant, they encourage the growth of sooty mould on the honeydew the insects produce, which cuts out the light and reduces photosynthesis, stunting the plant's growth ...
