EAB Quarantine Information. 307 University Ave Colorado State University Fort Collins, CO 80523-1177 Bldg: Plant Sciences C201 Voice: 970-491-6781 Dr. Whitney Cranshaw This beetle was originally from eastern Asia, but was introduced into North America to control aphids. In the United States, Dynastes beetles are generally uncommon, although the beautiful, black-spotted eastern Hercules beetles, Dynastes tityus, is occasionally found in large colonies on trees. They are shy and do not like to be disturbed. [12] From 1875, several Western European countries, including Germany, Belgium, France, and Switzerland, banned imports of American potatoes to avoid infestation by L. [4] In 5 to 10 days, the adult beetle emerges to feed and mate. [40], Bacterial insecticides can be effective if application is targeted towards the vulnerable early-instar larvae. Species that occur within homes in Colorado, in approximate order, are the varied carpet beetle (Anthrenus verbasci), furniture carpet beetle (Anthrenus flavipes), and common carpet beetle (Anthrenus scrophulariae). First instars measure about 1.50 mm (0.059 in) long, and the last (fourth) instars measure 8 mm (0.31 in) in length. It is about 10 mm ( ⁄8 in) long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. [18] It may also cause considerable damage to tomato and eggplant crops with both adults and larvae feeding on the plant's foliage. You can easily identify them by the 10 alternating yellow and black stripes on their shells. Development through all the larval stages takes about 3 to 4 weeks and late stage larvae are lighter red. Management Strategies for Private Property Owners. The beetles are orange-yellow in colour with 10 characteristic black stripes on their elytra. Click beetles, also known as Elateridae, can snap the front and back sections of its body together to make a clicking sound, and it can also use this motion to flip itself over if it gets stuck on its back. Apple Flea Beetle Altica foliaceae LeConte. The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) [citation needed] species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families.Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Long-term increased cost to the Michigan potato industry caused by insecticide resistance in Colorado potato beetle was estimated at $0.9 to $1.4 million each year. The area behind their heads is orange-yellow. They are sometimes found congregating on snowfields. The Colorado potato beetle (Leptinotarsa decemlineata), also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle, or the potato bug, is a major pest of potato crops. The Colorado beetle was introduced to Europe through trade and is now found throughout Asia and the rest of the world. Springtails: Springtails are one of the most common insects in Colorado. Found feeding on crops in North America and Europe. In East Germany, they were known as Amikäfer ('Yankee beetles') following a governmental claim that the beetles were dropped by American planes. EAB Colorado Photo Gallery. Its spread eastward was rapid, at an average distance of 140 km per year. [44] It has shown to be particularly effective as a biological pesticide for L. decemlineata when used in combination with B. Did not find a match for it on your website. The larvae are spiny, with a body that is slightly narrower at the head end, which is often tipped with a small tuft of hairs. Beetles represent the largest insect group with around 4,000 species in Britain and 300,000 worldwide. Identification, Biology, and Distribution. [40] The species as a whole has evolved resistance to 56 different chemical insecticides. In 1877, L. decemlineata reached the United Kingdom and was first recorded from Liverpool docks, but it did not become established. Size 0.24” to … © AfroBrazilian (CC BY-SA 4.0) via Wikimedia Commons Found throughout Britain, the common sexton beetle is a carrion or burying beetle - it buries, and lives off, small carcasses. For example, in 1956, Romania issued a set of four stamps calling attention to the campaign against insect pests,[50] and it was featured on a 1967 stamp issued in Austria. Colorado potato beetle The Colorado potato beetle (Leptinotarsa decemlineata Say). In the European Union, it remains a regulated (quarantine) pest for the Republic of Ireland, Balearic Islands, Cyprus, Malta, and southern parts of Sweden and Finland. Feeding can be inhibited by applying antifeedants, such as fungicides or products derived from Neem (Azadirachta indica), but these may have negative effects on the plants, as well. Colorado potato beetle (CPB), Leptinotarsa decemlineata, is a notorious destructive pest that mainly feeds on the leaves of potato and several other solanaceous plants. It is not established in any of these member states, but occasional infestations can occur when, for example, wind blows adults from Russia to Finland. [48], L. decemlineata is an iconic species and has been used as an image on stamps because of its association with the recent history of both North America and Europe. [4] It now has a wide distribution across Europe and Asia,[10] totalling over 16 million km2. One of the identifying features of beetles is … In fourth-instar larvae, about half the pronotum is coloured light brown. [19] Depending on temperature, light conditions, and host quality, the adults may enter diapause and delay emergence until spring. The beetle larva has four instar stages. There are a total of (96) Colorado Beetles found in the Insect Identification database. Different populations in different geographic regions have, between them, developed resistance to all major classes of insecticide,[40][41] although not every population is resistant to every chemical. There are a total of [ 51 ] Colorado Beetles in the BeetleIdentification.org database. They then return to their host plants to mate and feed; overwintering adults may begin mating within 24 hours of spring emergence. It is today considered to be the most important insect defoliator of potatoes. [12] By 1874 it had reached the Atlantic Coast. [9][6], The beetle is native to North America, and is present in every state and province except Alaska, California, Hawaii, and Nevada. These very large beetles are in the genus Dynastes, which is found throughout the Americas.Tropical species are among the largest insects in the world. They are also associated with other plants in this family, namely the species Solanum lycopersicum (tomato) and the genus Capsicum (pepper). [55], The fans of Alemannia Aachen carry the nickname "Kartoffelkäfer", from the German name for the Colorado beetle, because of striped yellow-black jerseys of the team. [23], In a laboratory experiment, Podisus maculiventris was used as a predatory threat to female L. decemlineata specimens, resulting in the production of unviable trophic eggs alongside viable ones; this response to a predator ensured that additional food was available for newly hatched offspring to increase their survival rate. Japanese beetle larvae are a type of white grub that feeds on the roots of grasses. [35] The steam distillate of fresh leaves and flowers of tansy (Tanacetum vulgare) contains high levels of camphor and umbellulone, and these chemicals are strongly repellent to L. EAB Incident Command Team Updates. Apart from their black color, you can identify black beetles by their hard shell, antennae, and pincers. [18], Native range of the potato and native and current range of the Colorado beetle, Expansion of the Colorado potato beetle's range in North America, 1859–1876, Expansion of the Colorado potato beetle's range in Europe, 1921–1964, Colorado potato beetle females are very prolific and are capable of laying over 500 eggs in a 4- to 5-week period.

[52], Neapolitan mandolins (also called Italian mandolins) are often called tater bugs,[53][54] a nickname given by American luthier Orville Gibson, because the shape and stripes of the different color wood strips resemble the back of the Colorado beetle. Go back to the Beetles State Listing. They are usually deposited in batches of about 30 on the underside of host leaves. The last major outbreak was in 1976. CPB is widely recognized for its adaptation to a remarkable variety of host plants and diverse climates, and its high resistance to insecticides and Bacillus thuringiensis toxins. We collect photographs of bugs from the United States and Canada for identification and research. Return to Results Page for Colorado Insects . [38], The large-scale use of insecticides in agricultural crops effectively controlled the pest until it became resistant to DDT in 1952 and dieldrin in 1958. This project is ongoing, and additional species may be added if requested and needed by Extension personnel. "Potato beetle" redirects here. It can be up to 20mm in length. [48] A widespread campaign was launched against the beetles; posters were put up and school children were mobilized to gather the pests and kill them in benzene or spirit. [4][8] This tribe is characterised within the subfamily by round to oval-shaped convex bodies, which are usually brightly coloured, simple claws which separate at the base, open cavities behind the procoxae, and a variable apical segment of the maxillary palp. BASICS. [39] Insecticides remain the main method of pest control on commercial farms. Native to the Rocky Mountains,[3] it spread rapidly in potato crops across America and then Europe from 1859 onwards. Upon reaching full size, each fourth instar spends several days as a nonfeeding prepupa, which can be recognized by its inactivity and lighter coloration. The Colorado potato beetle was first observed in 1811 by Thomas Nuttall and was formally described in 1824 by American entomologist Thomas Say. Identifying Large Beetles 1 Identify a click beetle by a narrow, long body and a clicking sound. The same experiment also demonstrated the cannibalism of unhatched eggs by newly hatched L. decemlineata larvae as an antipredator response. The specific name decemlineata, meaning 'ten-lined', derives from this feature. Adults have black heads with orange marks, round vibrant orange and/or yellow exoskeletons, and ten black stripes.

[5], Adult beetles typically are 6–11 mm (0.24–0.43 in) in length and 3 mm (0.12 in) in width. [4], Late (4th) instar stage of larva, before pupation, L. decemlineata has a strong association with plants in the family Solanaceae, particularly those of the genus Solanum. [4] From 1871, American entomologist Charles Valentine Riley warned Europeans about the potential for an accidental infestation caused by the transportation of the beetle from America. They quickly fly from plant to plant and have ten stripes on their backs. [24], Around 1840, L. decemlineata adopted the cultivated potato into its host range and it rapidly became a most destructive pest of potato crops.

[47], During the Cold War, some countries in the Warsaw Pact claimed that the beetles had been introduced by the CIA in an attempt to reduce food security by destroying the agriculture of the Soviet Union. [14] A cost-benefit analysis from 1981 suggested that the cost of the measures used to exclude L. decemlineata from the UK was less than the likely costs of control if it became established. Dung beetle feed partly or exclusively on the excrement of herbivores or omnivores. [21], At least 13 insect genera, three spider families, one phalangid (Opiliones), and one mite have been recorded as either generalist or specialized predators of the varying stages of L. decemlineata. [43], Beauveria bassiana (Hyphomycetes) is a pathogenic fungus that infects a wide range of insect species, including the Colorado potato beetle. [4] The genus Leptinotarsa is assigned to the chrysolmelid beetle tribe Doryphorini (in subfamily Chrysomelinae), which it shares with five other genera: Doryphora, Calligrapha, Labidomera, Proseicela, and Zygogramma.

These beetles were found near Grand Junction, CO in a prairie dog town and are specific to prairie dog poo. After World War II, in the Soviet occupation zone of Germany, almost half of all potato fields were infested by the beetle by 1950. L. juncta also has alternating black and white strips on its back, but one of the white strips in the center of each wing cover is missing and replaced by a light brown strip. Found a horned beetle eating the leaves of my Kiwi vines in SW Ontario Canada just after a couple of days of strong Westerly winds eminating from Texas. Larvae may defoliate potato plants resulting in yield losses up to 100% if the damage occurs prior to tuber formation. In fact, it can detect the scent of rotting flesh a mile away. [35] Other forms of pest control, through nonpesticidal management are available. The population increased dramatically during and immediately following World War II and spread eastward, and the beetle is now found over much of the continent. Kingdom Animalia (Animals) Phylum Arthropoda (Arthropods) Class Insecta (Insects) Order Coleoptera (Beetles) [35] Larvae may consume 40 cm2 of potato leaves during the entire larval stage, but adults are capable of consuming 10 cm2 of foliage per day. Larvae progress through four distinct growth stages (instars). It is about 10 mm (3⁄8 in) long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. ≠ This well-known insect was discovered about 1823 by Long's exploring expedition to the Rocky Mountains, in the region of the upper Missouri River. Another distinctive characteristic is the solidly colored black … [35] One 1984 study showed that rotating potatoes with nonhost plants reduced the density of early-season adults by 95.8%. The stripes are slim and alternate between yellow-orange and black on the wing covers. Back to Index: Collembola: Hypogastruridae Hypogastrura sp. It gets its name from its most-loved plant, the potato, but it’s also known by other names due to its coloring. Colorado, the beetles are most commonly observed in high-elevation spruce forests above 9,000 feet. Extension has resources to help identify insects and appropriate control measures. [3] The beetles were collected in the Rocky Mountains, where they were feeding on the buffalo bur, Solanum rostratum. Watch the video of a dung beetle on prairie dog feces However, many chemicals are often unsuccessful when used against this pest because of the beetle's ability to rapidly develop insecticide resistance. [36], The economic cost of insecticide resistance is significant, but published data on the subject are minimal. Japanese Beetle Program Web Page. The head remains black throughout these stages, but the pronotum changes colour from black in first- and second-instar larvae to having an orange-brown edge in its third-instar. Contact Info. They have a creamy white body with a dark head and the legs on the thorax are well developed. However, as spruce beetle population levels in downed trees increase, usually following an avalanche or windthrow event – a high-wind event that Colorado potato beetles, aka potato bugs, are about 1/4 to 1/2 inch long. [7], The orange-pink larvae have a large, 9-segmented abdomen, black head, and prominent spiracles, and may measure up to 15 mm (0.59 in) in length in their final instar stage. Beetles are found throughout the United States - reaching as far out as Hawaii, Alaska, and territories inbetween. Adults of this beetle have a black and cream- colored irregular checkered pattern on their wing covers (elytra) (Figure 11). Entries are listed below in alphabetical order (A-to-Z). Two strains of the bacterium Bacillus thuringiensis produce toxins that kill the larvae. These include the ground beetle Lebia grandis, the coccinellid beetles Coleomegilla maculata and Hippodamia convergens, the shield bugs Perillus bioculatus and Podisus maculiventris, various species of the lacewing genus Chrysopa, the wasp genus Polistes, and the damsel bug genus Nabis. You can always go back to the Insects by State Listing. [42] The mechanisms used include improved metabolism of the chemicals, reduced sensitivity of target sites, less penetration and greater excretion of the pesticides, and some changes in the behavior of the beetles. It is directly associated with Egg mass on underside of leaf. [18] Rotation may delay the infestation of potatoes and can reduce the build-up of early-season beetle populations because the adults emerging from diapause can only disperse to new food sources by walking. Field Biology and Identification. An adult L. grandis may consume up to 23 eggs or 3.3 larvae in a single day. Native to the Rocky Mountains, it spread rapidly in potato crops across America and then Europe from 1859 onwards. Colorado beetle identification.

Adults feed for a short time in the spring, and then begin to mate and lay clusters of 10-30 eggs on the undersides of leaves. [22], The predatory ground beetle L. grandis is a predator of both the eggs and larvae of L. decemlineata, and its larvae are parasitoids of the pupae. Hercules Beetles, Genus Dynastes. Entries are listed below in alphabetical order. It's been in Iowa for over 150 years and has a long history of devastating outbreaks. Eggs are laid in clusters and are a bright orange in coloration. User Tip: Click on the "X" found on each entry below to hide specific bugs from this page's listing. [16][17], The beetle has the potential to spread to temperate areas of East Asia, India, South America, Africa, New Zealand, and Australia. The dung is used as a food source or a brooding chamber. This one is the Asian Lady beetle, Harmonia axyridis. The estimate of the cost implication of insecticides and crop losses per hectare is $138–368. At endemic or low population levels, spruce beetles generally infest only downed trees. see pp. Colorado Potato beetles (CPB) have stout, oval bodies that are striped. We summarize our findings in guide pages for each order, family, genus, and species. [46], Other cultural controls may be used in combination with crop rotation: Mulching the potato crop with straw early in the growing season may reduce the beetle's ability to locate potato fields, and the mulch creates an environment that favours beetle's predators; Plastic-lined trenches have been used as pitfall traps to catch the beetles as they move toward a field of potatoes in the spring, exploiting their inability to fly immediately after emergence; flamethrowers may also be used to kill the beetles when they are visible at the top of the plant's foliage. Black beetles that invade homes tend to be smaller in size than the ones you may find crawling around your yard. It remains as a notifiable quarantine pest in the United Kingdom and is monitored by DEFRA to prevent it from becoming established. It was found on 5 August 2009 in Colorado Springs, CO. [51] The beetle also appeared on stamps issued in Benin, Tanzania, the United Arab Emirates, and Mozambique. [11], Its first association with the potato plant (Solanum tuberosum) was not made until about 1859, when it began destroying potato crops in the region of Omaha, Nebraska. [56][57], During the 2014 pro-Russian unrest in Ukraine, the word kolorady, from the Ukrainian and Russian term for Colorado beetle, (Ukrainian: жук колорадський, Russian: колорадский жук) gained popularity among Ukrainians as a derogatory term to describe pro-Russian separatists in the Donetsk and Luhansk Oblasts (provinces) of Eastern Ukraine.
