Common Name: Southern green stink bugScientific name: Nezara viridula (L.). Worldwide: tropical and subtropical regions of Africa, the Americas, Asia, Australasia, and Europe. Facts: The southern green stink bug has one of the widest host ranges of any insect pest. From their original appearance in eastern Pennsylvania just 20 years ago, theyve spread to 33 states, have just gotten to Wisconsin, and a separate population is building along the Pacific coast. Their shield-shaped bodies average a chunky half-inch and their five-segmented antennae explain the family namePenta(five) and tomos(section). When such an efficient (and host-specific) biological control exists, the lab folks try to mass-produce them, but TSSBs can be tricky to rear because they dont thrive on artificial foods. Disclaimer: Dedicated naturalists volunteer their time and resources here to provide this service. The TSSB specializes in Colorado Potato Beetles, and now that the Potato Beetle has skipped across The Pond to Europe, the TSSB has been introduced there too.

Several generations can be produced each year.
Squitier, J.M. In one study, a nymph ate 285 eggs, 3.7 larvae and 5.1 adult potato beetles on the way to adulthood. Their piercing-injecting-sucking causes mechanical damage (holes) and chemical injury that kills or stunts plants or inflicts cosmetic damage on fruits. Development from egg to adult requires about 35 days, but varies with temperature. 225-578-4143

The red and green or red-backed stink bug (Banasa dimiata)(a.k.a. Southern green stink bugs may occasionally attack rice in Louisiana. According to a study done in 1923, the red in the TSSB comes from carotenes it ingests while feeding on the gold-colored lymph of adult and larval Colorado potato beetles. And corn and soybeans. In some cases, the leaf will fold along these perforations and the tip will break off leaving a ragged edge.
in length, 0.75 mm (0.03 in.) Click for a hub of Extension resources related to the current COVID-19 situation. The BugLady has always had a soft spot in her heart for stink bugs. This type of damage has been called cat facing. When ripened or nearly ripened fruit is injured, the injection of toxic saliva merely kills a cluster of cells that later forms an off-color hard mass in the fruit, reducing fruit quality and producing a bad flavor to the fruit. Theyre also having a profound impact on non-farmers. University of Georgia, Col. Ag. One stink bug species, Brochymena arborea (Say), closely resembles the color and texture of tree bark on which it lives. The story of rough stink bugs (this one is probably Brochymena quadripustulata, the Four-humped Stink Bug) is a contradictory one. Heres a sampling of Wisconsin SBs, all of which are pretty common nation-wide. The time from egg to adult is 35 - 57 days, depending on temperature. The eggs are white to light yellow. The degree of damage depends, to some extent, on the developmental stage of the plant when it is pierced by stink bugs. 34: 273-92. Immature fruit and pods punctured by bugs become deformed as they develop. In fruit, such as tomatoes, damage is of two types. The first instar TSSB nymph feeds on juices from potato plants, but then it switches to potato beetles.

Mexico, extremely polyphagous: recorded from 20 plant families. Southern green stink bugs overwinter as adults. SBs use their piercing-sucking mouthparts to inject a saliva that pre-digests their food, and the mouthparts are tucked under their chin when not in use. Not surprisingly then, it is occasionally a pest of rice. The Bug Lady once saw a picture of a group of stink bug nymphs clustered around their recently-vacated eggs. Some sources list them as herbivores, targeting fruit trees, and others list them among the predaceous SBs. Brown stink bug nymphs are usually pale green. Habitat, Food Source(s), Damage: The southern green stink bug feeds on a wide variety of developing fruit, including cotton, peaches and tomatoes, and seeds such as pecan, sorghum and soybeans. Brown stink bug eggs are white, kettle-shaped, and slightly smaller than those of the green stink bug. For this reason, you will find a series of perforations that run around the diameter of the unfurled leaf from one edge to the other. Summer and Fall 2022 Workshop Registration, Chronological Index to the Field Station Bulletin. Stink bugs feed on developing seed of many hosts including trees, shrubs, vines, weeds and many cultivated crops. The potential controlspheromone traps, BMSB birth control, and parasitic wasps, are years down the road. http://wiki.bugwood.org/index.php?title=Archive:GATop50/Stink_Bugs&oldid=31371, Center for Invasive Species and Ecosystem Health at the University of Georgia, This page was last modified 20:20, 12 October 2010 by.

For additional information, contact your local Texas A&M AgriLife Extension Service agent or search for other state Extension offices. The amount of saliva needed was far beyond what any SB carries around with it, so they must be able to produce it easily. Please see the Rice section of the Insect Pest Management Guide on the LSU AgCenter's Management Guides webpage. The saliva both diluted the glue on the strands of web and made them less elastic.

The caption explained that they were eating their eggs, and that as they did so they were ingesting bacteria left behind from their mothers gut that would set up shop in their guts and allow them to digest the cellulose materials they ate! Green stink bugs (Chinavia or Acrosternum hilaris) (probably) suck juices from a variety of agricultural crops like tomatoes, peas, corn and soybeans and from fruit trees and their seeds. Adults will commonly switch host plants.
We strive to provide accurate information, but we are mostly just amateurs attempting to make sense of a diverse natural world.
She likes the name stink bug and the chemical warfare that earned that name; they come in a rainbow of colors and even the nymphs are pretty. Life Cycle: Simple metamorphosis; adults deposit barrel-shaped eggs; immature stages develop through five stages or instars that appear similar to adults except that they do not have fully developed wings. Entomol. However, the immature stages have a distinctive pattern of whitish spots on the abdominal segments. Maternal care has been recorded for some species of stink bugs. Winter School Top Fifty Agricultural Insect Pests and Their Damage Sessions, Rock Eagle 4-H Ctr., Jan. 20, 1999. Their scent is almondy suggesting a possible cyanide component. Stink bugs are in the family Pentatomidae, and their family tree includes some voracious, crop-damaging plant feeders (many stink bugs are somewhat resistant to pesticides) as well as some species that eat their brethren.
Scientific Name: Nezara viridula (Linnaeus)
Development from egg to adult requires about 5 weeks, but varies with temperature. Nymphs develop through five instars that resemble adults but aresmaller and oval. They seem to be out-competing native SBs. Occasionally though, Eisner saw a spider get hit full force by the chemical, early in its processing of the SB. 225-578-4161 The adult is shield-shaped about - to 3/4-inch in length with an overall dull green color. Stink bugs may be controlled with a variety of insecticides, however, many crops have specific action thresholds that should be observed to provide the most economically efficient control.

In 2005 it was classified as Chinavia hilaris. They become active in spring when temperatures rise above 210C (700F). Nymphal stages are often found together in high numbers because eggs are laid in clusters that appear as rows of small barrels on and around suitable food sources. Up to five generations per year may occur with greater numbers appearing in the fall before adults overwinter. They also feed on the parts of many ornamental and wild plants. Individuals progress through five nymphal instars. Assessing genetic diversity in four stink bug species, Chinavia hilaris, Chlorochroa uhleri, Chlorochroa sayi, and Rider D.

Some SBs have earned the nickname catfacing insect because of the cat-faced scars that are left by their browsings. They dont bite, but they do stink, and they do fly through the house, lodge in AC filters, and congregate in boots and coat pockets and closets. Featured creature fact sheets: southern green stink bug, Nezara viridula (Linnaeus) (Insecta: Hemiptera: Pentatomidae). Odor isnt a foolproof deterrent; most birds have no sense of smell and happily chow down on them, one parasitic wasp finds SBs by their defensive scent, and some feather-legged flies (whose maggots are parasitoids) are attracted to the SBs pheromones.

Even though the problem is sporadic, when southern green stink bugs feed on rice, they can cause significant damage. Usually it is first noticed as dead or dying leaves on isolated plants or groups of plants. There are a number of different species of stink bugs common in Texas, including: the conchuela stink bug, Chlorochroa ligata (Say); the brown stink bug, Euschistus servus (Say); the harlequin bug, Murgantia histrionica (Hahn); the rice stink bug, Oebalus pugnax (Fabricius); and the spined shouldered stink bug, Podisus maculiventris (Say). Stink bugs prefer wild hosts. First, he describes the stink bugs stink as persistent. When an SB discharges its scent gland, some of the liquid is trapped on a rough surface near the slit that acts like a sponge, retaining some of the chemical for a lingering effect. 2022 BugGuide gathering in New Mexico July 20-24! Baton Rouge, LA 70803. An SBs piercing-sucking mouthparts are not designed for chewing through spider web; instead, it applied its corrosive saliva to the web where the web touched its legs or body and used its legs to spread the saliva around.
It was crawling on the screen. Later, the name was changed to Acrosternum hilaris. Adult green stink bugs are bright green with a narrow orange-yellow line bordering the major body regions.
Here are a few great SB stories from For Love of Insects, by the renowned entomologist Thomas Eisner. One homeowner (ironically, a scientist who studies invasive species) reported vacuuming 8,000 BMSBs from his attic in a single day; his three-month total was almost 22,000. If Alfred Hitchcock had done a movie about insects, he might have chosen the alien brown marmorated stink bug (Halyomorpha halys). Meanwhile, the SB took advantage of the distraction and escaped, but Eisner was amazed by its method. 1989. Env. Injured plants will often have a piercing injury that was inflicted when the leaf was rolled. Pest Status: Plant feeder; has well developed scent glands and will emit a distinctive disagreeable odor when handled; medically harmless.
In those cases, the spiders reaction was dramaticit fled the scene, regurgitated, and used its legs to clean itself, which included drawing appendages through its mouth as if wiping the chemical off. According to Waldbauer in The Handy Bug Answer Book, when an experimenter removed the guarding female from some clutches of eggs but not from others, none of the unguarded eggs survived and only half of the guarded eggs survived. The second story has to do with SBs and spiders. Populations build up on wild host plants, and adults may move to crops late in the season as preferred foods mature. 1999. Description: Adults are about 1/2 to 3/4-inch in length and are solid green. By the time the spider delivers the coup de grace, any resulting spray is trapped in the web envelope and generally diffused into the air. Ann. http://insects.tamu.edu/fieldguide/index.html, http://insects.tamu.edu/fieldguide/aimg73.html. Later instar nymphs polish off 59 beetle eggs per day, and adults eat 85 beetle larvae in six weeks. The BugLady thinks they look like tiny painted turtles. Meadow. Damaged areas are usually localized in a field rather than uniform throughout. Eastern Pennsylvania. The two common Georgia stink bugs discussed below are the green stink bug (Acrosternum hilare) and the brown stink bug (Euschistus servus). Nezara viridula (Hemiptera: Pentatomidae). An SB caught in a web is generally a goner. Spiders quite efficiently bite and wrap their prey, and many can thus immobilize SBs without allowing the SB to spray.
Brown stink bugs (Euschistus sp.) SB nymphs manufacture chemicals in internal glands are on the top side of their abdomen (a location that will be covered by wings when they are adults), adults in one gland on the thorax. This area of the fruit stops expanding, while the cells around the dead cells continue to expand by increasing their water content. How you can manage southern green stink bug: Parasites (wasps and flies) might provide sufficient biological control of the southern green stink bug.
Some plant diseases are spread by stink bug feeding.
The nymphs develop through five stages, varying in color from black for very small nymphs to green for larger nymphs. Most are plant feeding although a few, such as the spined shouldered stink bug are predaceous on other insects. University of Florida. The chemical is released through slits in the exoskeleton; the adults gland has two openings, and they can spray left or right or both. When the young green fruit is injured, the cells at the site of feeding are killed by the toxic saliva injected by the bugs into the plant. Location: On West Rush Lake near Rush City in the yard and in the house, Pembina Trail Preserve SNA, Pembina Trail Unit, Hemiptera (true bugs, cicadas, hoppers, aphids and allies), Pentatomoidea (stink bugs, shield bugs, and allies). Ecology and behavior of Nezara viridula . Green stink bug eggs are barrel-shaped measuring 1.4 x 1.2 mm. 1.0 mm (0.04 in.) Sometimes called tree stink bugs, they are well-camouflaged on tree bark. Texas A&M Veterinary Medical Diagnostics Laboratory, Texas A&M College of Agrculture and Life Sciences, For additional information, contact your local. Stunted plants, killed growing points and dead leaves are all signs of stink bug injury. The damage caused by southern green stink bugs feeding on rice may be confined to an area as small as 3 feet in diameter to several acres in size.
Adult brown stink bugs are shield shaped and dull, grayish-yellow with dark punctures on their backs. Nymphs hatch and pass through five instars before becoming adults. Todd, J.W. The imprisoning strands broke, the SB slid down and got trapped on a new, sticky section of web, and repeated the process, over and over, until it got to the bottom edge of the web. Pink to bright orange just prior to hatching. Common Name: Southern green stink bug All adult stink bugs are shield shaped. This species was originally named Pentatoma hilaris. Approximately 4 to 5 weeks elapse between hatching and adult emergence. Stink bugs overwinter as adults in ditch banks, under boards orother similar materials. After she lays her cluster of keg-shaped eggs, some females stay and guard them. Baton Rouge, LA 70803 Here in the (snooty) Western World, we turn up our noses at entomophagy (the science of eating insects) but SBs have found their way into the cuisines of Mexico and of several southeast Asian cultures (where their strong spicy odor is appreciated). Immature stages vary in color from black for very small nymphs to green for larger nymphs. A partial list includes: Feeds preferentially on young, developing fruits. As many as five generations per year may occur with greater numbers appearing in the fall before adults overwinter.

Eggs are deposited in clusters on the underside of leaves or on fruiting structures. Attached is a photo of what google lens identified as a green stink bug nymph. It seems that like box elder bugs, BMSBs gather on the outsides of homes in fall, plotting to get inside. All Citrus species and their hybrids, but particularly destructive to common mandarins (including tangerine), Citrus reticulata. The numbers of this insect in rice field are usually below levels justifying treatment, but they may increase rapidly under favorable conditions and yield losses can occur. Weevils and Borers. They are yellow to green, later turning pink to gray. The result is deformed fruit that appears to have dimples.
