Contents

Diorhabda meridionalis is a species of leaf beetle known as the southern tamarisk beetle (SoTB) which feeds on tamarisk trees from Syria to western and southern Iran and southern Pakistan. [1] The SoTB may have potential for use in North America as a biological pest control agent against saltcedar or tamarisk ( Tamarix spp.), an invasive species in arid and semi-arid ecosystems (where it might be less accurately referred to along with its closely related sibling species as the 'saltcedar beetle', 'saltcedar leaf beetle', 'salt cedar leaf beetle', or 'tamarisk leaf beetle') (Tracy and Robbins 2009).

Taxonomy

The SoTB was first described from Minab, Iran as the subspecies Diorhabda carinulata meridionalis Berti and Rapilly (1973). Tracy and Robbins (2009) recognized Diorhabda meridionalis Berti and Rapilly as a separate species from Diorhabda carinulata (Desbrochers) based on comparisons of the male and female genitalia, and provided illustrated taxonomic keys separating the SoTB from the four other sibling species of the D. elongata (Brullé) species group: Diorhabda elongata (Brullé), Diorhabda carinata (Faldermann), Diorhabda sublineata (Lucas), and Diorhabda carinulata . (For additional information, see Wikispecies-logo.png Wikispecies: Diorhabda meridionalis .)

Host plants

Field collections in Iran reveal that the SoTB feeds on an unidentified species of tamarisk. [2] Further field collections are needed to identify which tamarisk species serve as hosts.

Life cycle

The life cycle of the SoTB has not been studied, but it is probably similar to that of the closely related northern tamarisk beetle, Diorhabda carinulata .

Biological control agent

The SoTB might be able to serve as an effective biological control agent for tamarisk in North America. Laboratory host range studies are needed to verify that SoTB is a specialist feeder on tamarisks. The SoTB may be better adapted to subtropical desert habitats of south and west Texas than other Old World tamarisk beetles that are being introduced, such as the Mediterranean tamarisk beetle, Diorhabda elongata . The northern tamarisk beetle, Diorhabda carinulata , is probably better adapted to northern cold deserts in North America where it is widely established, and the larger tamarisk beetle, Diorhabda carinata , is probably better adapted to warm temperate grasslands and deserts. The subtropical tamarisk beetle, Diorhabda sublineata , is probably better adapted to subtropical Mediterranean and subtropical interior desert habitats (Tracy and Robbins 2009). (See articles on other tamarisk beetles listed above for additional information on biological control.)

Beetle Order of insects

Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils), with some 83,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.

Biological pest control Method of controlling pests using other living organisms

Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.

Willow flycatcher

The willow flycatcher is a small insect-eating, neotropical migrant bird of the tyrant flycatcher family. There are four subspecies of the willow flycatcher currently recognized, all of which breed in North America. Empidonax flycatchers are almost impossible to tell apart in the field so biologists use their songs to distinguish between them. The binomial commemorates the Scottish zoologist Thomas Stewart Traill.

<i>Tamarix</i> Genus of plants

The genus Tamarix is composed of about 50–60 species of flowering plants in the family Tamaricaceae, native to drier areas of Eurasia and Africa. The generic name originated in Latin and may refer to the Tamaris River in Hispania Tarraconensis (Spain).

Silverleaf whitefly

The silverleaf whitefly is one of several species of whitefly that are currently important agricultural pests. A review in 2011 concluded that the silverleaf whitefly is actually a species complex containing at least 40 morphologically indistinguishable species.

Scarlet lily beetle Species of beetle

The scarlet lily beetle, red lily beetle, or lily leaf beetle, is a leaf beetle that eats the leaves, stem, buds, and flowers, of lilies, fritillaries and other members of the family Liliaceae. It lays its eggs most often on Lilium and Fritillaria species. In the absence of Lilium and Fritillaria species, there are fewer eggs laid and the survival rate of eggs and larvae is reduced. It is now a pest in most temperate climates where lilies are cultivated.
