The green stink bug or green soldier bug (Chinavia hilaris) is a stink bug of the family Pentatomidae.
The species was previously placed in the genus Acrosternum but has been classified as in the genus Chinavia in the more recent literature (e.g., Schwertner and Grazia, 2006). However, the Entomological Society of America has not officially recognized this change despite this shift in scientific naming. [1]
The green stink bug's color is typically bright green, with narrow yellow, orange, or reddish edges. It is a large, shield-shaped bug with an elongate, oval form and a length between 13 and 18 mm. It can be differentiated from the species Nezara viridula by its black outermost three antennal segments. Its anterolateral (= in front and away from the middle) pronotal margin is rather straight and not strongly arced such as in Chinavia pensylvanica . Both adults and nymphs have large stink glands on the underside of the thorax extending more than half-way to the edge of the metapleuron. They discharge large amounts of this foul-smelling liquid when disturbed. This liquid, dried and pulverized, was once used at industrial level to reinforce the smell of some acids. Now it's been replaced by artificial composites.
This species is found in orchards, gardens, woodlands and crop fields throughout North America, [2] feeding with their needle-like mouthparts on the juices of a wide variety of plants from May until the arrival of frost. Their range spans from the eastern United States, from New England to Florida, to the 98 degree west longitudinal line; they are also seldom found anywhere west of this boundary, though are found moderately along the west coast, from San Diego, California to Seattle, Washington. [3] Adults develop a preference for developing seeds and thus become crop pests (tomato, bean, pea, cotton, soybean, eggplant). When no seeds are present, they also feed on stems and foliage, thus damaging several fruit trees, such as the apple, cherry, orange and peach trees.
Green stink bugs frequent noncrop hosts more than other stink bug species earlier in the season. Plants such as black cherry, elderberry, mimosa and pecan exist as farmscape edges, which provide immature organisms a safe location to develop and a gateway to agricultural fields. Unlike cotton, peanuts and corn are not considered host crops, and the last has been shown to slow dispersion of green stink bug to nearby host crops due to its tall field edges. [4]
Adults appear in the field early September and become plentiful in sheltered positions. Then, mating happens in early October and finally, the eggs can be found mid to late October. Nymphs appear in late October and early November. Two or three generations occur in the summer months in the field and in the laboratory at 26 °C. [5]
The adult females attach their keg-shaped eggs on the underside of foliage in double rows of twelve eggs or more. These clusters appear almost cylindrical, and they transition from light green, to yellow, to light pink as organisms approach hatching. Time from egg deposition to hatch decreases with rises in temperature.[ citation needed ] The green stink bug produces one generation in the North and two generations in the South. The early instar nymphs are rather brightly colored and striped, turning green when approaching adulthood. The eggs are usually laid in clusters of 14 (some clusters contain fewer eggs, with 9 being the smallest number recorded out of 77 observations). The eggs are laid either on the undersurfaces of leaves or on the stems of plants or on the flowers of salvia. [5]
The green stink bug is considered to be a pest of economic importance in the United States. Crops are considered to be damaged when plant tissue is split by the feeding stylet. Most damage is administered by adults; effects can include catfishing (the misshaping of plant tissue, creating rough and corky edges) in peaches, internal warts and stained lint within cotton, green stem syndrome in soybeans and white spongy areas on tomatoes. Any dimples or scars on fruit are most likely administered by nymphs. On occasion, the laying of eggs on grapes causes said nymphs to deplete the juices from the growing fruits. [6]
This stink bug species is parasitized by the tachinid fly Trichopoda pennipes [7] and by parasitic wasps. [8]
The green stink bug uses the pheromone methyl (E,Z,Z)-2,4,6-decatrienoate in its communication system and this may be used to attract the bug away from crop fields. [9]
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.
Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species. As hemipterans, the pentatomids have piercing sucking mouthparts, and most are phytophagous, including several species which are severe pests on agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial.
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.
Blissus leucopterus, also known as the true chinch bug, is a small North American insect in the order Hemiptera and family Blissidae. It is the most commonly encountered species of the genus Blissus, which are all known as chinch bugs. A closely related species is B. insularis, the southern chinch bug.
The green shield bug is a Palearctic shield bug species in the family Pentatomidae. The name might equally apply to several other species in the tribe Nezarini, or if referred-to as a "green stink bug", it might more appropriately belong to the larger North American bug, Chinavia hilaris. The adult green shield bug ranges in the colour of their backs from bright green to bronze, without any substantial markings. Green shield bugs are a very common shield bug throughout Europe, including the British Isles, and are found in a large variety of habitats, including gardens. They have been found as far north as 63° N latitude.
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.
Adelphocoris lineolatus, is commonly known as the Lucerne bug or the alfalfa plant bug, and belongs to the family Miridae. It is an agricultural pest causing vast amounts of damage to numerous crops, but primarily to alfalfa crops around the globe.
Nezara viridula, commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug, is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found across the world. Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops.
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.
Trichopoda pennipes is a species of feather-legged fly in the dipteran family Tachinidae.
Tessaratomidae is a family of true bugs. It contains about 240 species of large bugs divided into 3 subfamilies and 56 genera.
Dysdercus koenigii is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton staining fungi as they do so.
Euthyrhynchus floridanus, the Florida predatory stink bug, is a species of carnivorous shield bug in the family Pentatomidae, the only species in the genus Euthyrhynchus. It is native to the hottest parts of the southeastern United States and is considered beneficial because its diet includes many species of pest insects.
Piezodorus guildinii, known generally as red-banded stink bug, is a species of stink bug in the family Pentatomidae. Other common names include the small green stink bug and alfalfa bug.
Proxys punctulatus, the black stink bug, is a species of stink bug in the family Pentatomidae. It is found in the Caribbean Sea, Central America, and North America.
Monteithiella humeralis, commonly known as the pittosporum shield bug is a species of herbivorous shield bug native to Australia and introduced in New Zealand. As its common name suggests, it is most commonly observed feeding on Pittosporum plants.
Chinavia is a genus of green stink bugs in the family Pentatomidae. There are more than 30 described species in Chinavia.
Cuspicona simplex, commonly known as the green potato bug, is a herbivorous species of stink bug native to Australia and introduced to New Zealand. It feeds on nightshades. It is primarily known as a pest of potatoes, tomatoes, and other crops in the nightshade family.
Erthesina fullo, commonly known as the yellow-spotted stink bug or yellow marmorated stink bug, is a species of stink bug in the family Pentatomidae. It is found in east and southeast Asia. It is one of the most widely distributed phytophagous insect pests in Asia, and feeds on dozens of host plants including a number of economically important fruits, such as apples, cherries, pears and kiwifruit.
Edessa rufomarginata, also known as red-bordered stink bug, is a species of stink bug. The species was originally described by Charles De Geer in 1773.
