Monteithiella humeralis, commonly known as the pittosporum shield bug is a species of herbivorous shield bug native to Australia and introduced in New Zealand. [1] As its common name suggests, it is most commonly observed feeding on Pittosporum plants.

Description

Monteithiella humeralis adults are 9mm long with predominantly brown bodies and pale green legs. [2] First instar nymphs are small and black, with circular bodies and white spots on the upper surface of the abdomen. [3] Later nymph stages are similar to the first but with orange spots instead of white.

Life history

Adult females lay blue eggs on the underside of leaves which turn white after 2–3 days, and hatch after 5 days. [4] Nymphs progress through 5 instars or juvenile stages before reaching adulthood. It takes around 41 days after eggs are laid for bugs to mature to adulthood. In New Zealand, adults are most abundant in November and March. [2] while eggs and nymphs can be found from November to April. [5]

Ecology

In both New Zealand and Australia, pittosporum shield bugs are most commonly found feeding on species of Pittosporum , and to a lesser extent Coprosma . [2] [4] In New Zealand, pittosporum shield bugs are widespread but are not considered a pest. [2] They are known to be attacked by Trissolcus basalis , [2] a parasitoid of pentatomid egg masses introduced into New Zealand in 1949 to control Nezara viridula . [6]

<span class="mw-page-title-main">Pentatomoidea</span> Superfamily of true bugs

The Pentatomoidea are a superfamily of insects in the suborder Heteroptera of the order Hemiptera. As hemipterans, they possess a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs.

<span class="mw-page-title-main">Scutelleridae</span> Family of insects

Scutelleridae is a family of true bugs. They are commonly known as jewel bugs or metallic shield bugs due to their often brilliant coloration. With the name based on the Asian genus Scutellera, they are also known as shield-backed bugs due to the enlargement of the thoracic scutellum into a continuous shield over the abdomen and wings. This latter characteristic distinguishes them from most other families within Heteroptera, and may lead to misidentification as a beetle rather than a bug. These insects feed on plant juices from a variety of different species, including some commercial crops. Closely related to stink bugs, they may also produce an offensive odour when disturbed. There are around 450 species worldwide.

<span class="mw-page-title-main">Peloridiidae</span> Family of true bugs

The Peloridiidae or moss bugs are a family of true bugs, comprising eighteen genera and thirty-four species. They are small, ranging in length from 2 to 4 mm, rarely seen, peculiarly lumpy, flattened bugs found in Patagonia, New Zealand, eastern Australia, Lord Howe Island, and New Caledonia. Peloridiids are found amongst mosses and liverworts, commonly in association with southern beech forests. They have become known as moss bugs for their habit of feeding on mosses. Almost all Peloridiidae species are flightless, except one. Their present distribution suggests they have existed since before the breakup of Gondwana. They are the only living members of the suborder Coleorrhyncha, which first appeared in the Upper Permian, over 250 million years ago.

Acanthosomatidae is a family of Hemiptera, commonly named "shield bugs" or "stink bugs". Kumar in his 1974 world revision recognized 47 genera; now this number is 55 genera, with about 200 species, and it is one of the least diverse families within Pentatomoidea. The Acanthosomatidae species are found throughout the world, being most abundant in high-latitude temperate regions and in subtropical regions at high altitudes.

<span class="mw-page-title-main">Brown marmorated stink bug</span> Species of Pentatomid insect

The brown marmorated stink bug is an insect in the family Pentatomidae, native to China, Japan, Korea, and other Asian regions. In September 1998, it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010s, the bug has spread to countries such as Georgia and Turkey and caused extensive damage to hazelnut production. It is now established in many parts of North America, and has recently become established in Europe and South America.

<i>Bagrada hilaris</i> Species of true bug

Bagrada hilaris is a species of shield bug known by the common names bagrada bug and painted bug. It could be mistaken for or erroneously referred to as harlequin bug. It is native to southeastern Africa. It is known elsewhere as an introduced species, including California and Arizona, where it was first reported in 2008. It is a major pest insect of Brassica oleracea crops, and related crucifers such as turnips, rape, and mustard. The adult and nymph of the species suck sap from the leaves of the plants, causing wilting, yellowing, and stunting of growth. Besides crucifers, the bugs are known on papaya, sorghum, maize, potato, cotton, caper, pearl millet, and some legumes. Large numbers of the bug congregate on the plants and cause extensive damage.
