New Georgia Encyclopedia: Boll Weevil weevil greatly affected Georgia's long history of cotton production between 1915, when the insect was introduced to Georgia, and the early 1990s, when it was eliminated as an economic pest. The adult boll weevil measures from three to eight millimeters from the tip of the snout to the abdomen, which is half the length of its body. Upon hatching, the boll-weevil larvae or grubs feed in the square, causing it to be shed by the plant or rendering the bolls unsuitable for harvest. www.georgiaencyclopedia.org /nge/Article.jsp?id=h-2088   (863 words)

IPM : Field Crops : Alfalfa Weevil (Hypera postica Gyllenhal) The alfalfa weevil is one of the primary insect defoliators of alfalfa. The clover leaf weevil is green with a white stripe down the center of its back,but the white stripe is bordered with smudges of pink or red; the head of the clover leaf weevil is tan. Alfalfa weevil adults and larvae have the potential to prevent or slow regrowth by feeding on the new shoots; adults also feed on sides of the stems (bark feeding). www.ipm.uiuc.edu /fieldcrops/insects/alfalfa_weevil/index.html   (1582 words)

Pecan Weevil Alert The weevils have been so bad at times that the pecans from this area were severely discounted until there was not even a price offer for them. When the weevil bores a hole into a developing nut that is still in liquid or gel stage, the nut will abort and can be found on the ground within three days of being punctured. Weevil damage as represented by the nuts on the ground can be distinguished easily from other damage by the "tobacco stains" that developed from the fluids that ran out of the puncture hole. www.noble.org /Ag/Horticulture/Weevil   (753 words)

The Milfoil Weevil in Washington   (Site not responding. Last check: 2007-10-13) Weevil abundance began increasing in 1990 and peaked in June of 1992, where 3 - 4 weevils (adults and larvae) per stem were detected (Creed and Sheldon 1995). Weevil abundance, however, decreased with declining densities of Eurasian watermilfoil in 1996 and by September 1997 weevils were undetectable. The photograph of a milfoil weevil egg is used with the permission of L. Jester. www.ecy.wa.gov /programs/wq/plants/management/weevil.html   (821 words)

Alfalfa Weevil, FC-ENT-0032-00 Thus, the yield impact of weevil feeding on alfalfa declines as alfalfa stand height increases, and decisions to treat alfalfa for weevil should be focused on an alfalfa stand when larvae can be readily found on alfalfa that is 12 inches or less in height. Whenever weevil activity on an alfalfa stand is being evaluated, it is important that indicators of declining weevil activity be noted, such as the pupation of mature larvae or the decimation of a weevil population by an epizootic of the fungal pathogen. If few early weevil larvae are present in a sample and pupal cocoons are readily found on the foliage or on the ground, it may be assumed that the peak activity of larval feeding has passed. ohioline.osu.edu /ent-fact/0032.html   (1208 words)

Weevil - Wikipedia, the free encyclopedia The boll weevil (Anthonomus grandis) attacks cotton crops. Zyzzyva is a genus of tropical American weevils. Weevils are most likely to be observed in a domestic setting when opening a bag of flour although they will happily infest most types of grain including oats, barley and breakfast cereals. en.wikipedia.org /wiki/Weevil   (215 words)

Milfoil Weevil (E. lecontei) The milfoil weevil lays its eggs on milfoil plants, usually on apical meristems near the water surface (Sheldon and O'Bryan 1996a). Adult milfoil weevils are approximately 2-3 mm in length and have lived as long as 162 days in captivity (Sheldon and O'Bryan 1996a). Because the weevil is endemic to North America (Colonelli 1980, O'Brien and Wibmer 1982), and Eurasian watermilfoil probably was not established in North America until the 1940's (Smith and Barko 1990), it is evident that the original host was northern watermilfoil (Creed and Sheldon 1994a, Newman and Maher 1995). www.fw.umn.edu /research/milfoil/milfoilbc/weevil.html   (1323 words)

Weevil World   (Site not responding. Last check: 2007-10-13) The Weevil City was weeviless, and even though it was a serious act of vandalism to a monument that had stood in town for nearly 80 years at that point, the tale of it's assault appealed to the media as an amusing "fringe" story. My questions to her that sparked her quest for weevil knowledge were prompted by an author who contacted me seeking information on the weight of the boll weevil atop the monument. The boll weevil that the monument included from 1981 until it was torn off by vandals (ruining the monument) on July 30, 1998, weighs 17 pounds and is located at the Pea River Historical and Genealogical Society's Depot Museum in Enterprise. www.shelleybrigman.com /weevil.html   (2364 words)

IPM : Field Crops : Clover Leaf Weevil (Hypera punctata) It is often confused with the alfalfa weevil, one of the major insect pests of alfalfa. Adult alfalfa weevils are small brown beetles that have adistinctive dark, narrow stripe that extends down their back and about one quarter of the size of an adult clover leaf weevil. The clover leaf weevil is nocturnal, feeding atnight, and hiding during the day in the crown of the plant and in the debris on the ground. www.ipm.uiuc.edu /fieldcrops/insects/clover_leaf_weevil   (692 words)

Alfalfa Weevil   (Site not responding. Last check: 2007-10-13) The alfalfa weevil is a snout beetle about 1/4 inch in length and light brown in color with a dark brown, mid-dorsal band; This insect completes one generation per year. For effective control of weevil larvae, it is important that adequate spray volume is used for thorough coverage of alfalfa foliage; a minimum of 10 gal/acre with conventional ground equipment and 2-4 gal/acre for aerial application is recommended. Two natural enemies of the alfalfa weevil are wasps that parasitize weevil larvae and a fungal disease that kills both larvae and pupae. alfalfa.okstate.edu /webnews/alfweevil.htm   (746 words)

Program In laboratory tests this boll weevil pheromone was isolated by drawing air from caged males through a column of activated charcoal to which female weevils were quickly attracted. Yield losses attributed to the boll weevil, the cost of insecticide control, environmental considerations, infestation of secondary insects and insect resistance all have resulted in an aggressive effort to develop a beltwide strategy for controlling the boll weevil in the United States. In view of the economic and environmental problems posed by the boll weevil and in recognition of the technical advances developed over a period of almost 100 years by hardworking and talented scientists, a cooperative boll weevil eradication experiment was initiated in 1971 in southern Mississippi and in parts of Louisiana and Alabama. www.txbollweevil.org /Program_information/History.htm   (1461 words)

Alfalfa Weevil The alfalfa weevil is the most important insect pest of alfalfa in Colorado. The key to economical management of the alfalfa weevil is combining crop management practices, biological control and the use of insecticides only when weevil numbers are high enough to ensure that yield benefits outweigh treatment costs. Several natural enemies of the alfalfa weevil have been imported and established in Colorado by the Colorado Department of Agriculture, and new species continually are being imported and released. www.ext.colostate.edu /pubs/insect/05500.html   (1361 words)

Black Vine Weevil The fl vine weevil is also destructive in the larval form on yew (Taxus spp.), hemlock, rhododendron, and several other evergreens. Since the weevils do not fly, they disperse chiefly by walking, although they may be transported by man along with plants. Weevils may be feeding on leaf edges, especially near the trunk. www.uri.edu /ce/factsheets/sheets/blackvineweevil.html   (953 words)

sweetpotato weevil - Cylas formicarius (Fabricius) Sweetpotato weevil was first noted in the United States in Louisiana in 1875, and then in Florida in 1878 and Texas in 1890, probably entering by way of Cuba. Sweetpotato weevil is often considered to be the most serious pest of sweet potato, with reports of losses ranging from five to 97% in areas where the weevil occurs. A symptom of infestation by sweetpotato weevil is yellowing of the vines, but a heavy infestation is usually necessary before this is apparent. creatures.ifas.ufl.edu /veg/potato/sweetpotato_weevil.htm   (1970 words)

APHIS | News Once the boll weevil is eradicated from an area, growers typically experience an increase in cotton yield of at least 10 percent, significantly more in some areas. After the boll weevil is eradicated from an area, the need for insecticides is significantly reduced, and in many areas nearly eliminated. A. The boll weevil is considered the key pest in cotton production because the insecticides that cotton growers use early in the season to control weevils also eliminate many beneficial insects. www.aphis.usda.gov /lpa/pubs/fsheet_faq_notice/faq_phbweevil.html   (1737 words)

Alfalfa Weevil   (Site not responding. Last check: 2007-10-13) Alfalfa weevil and potato leafhopper are the most destructive insect pests that attack alfalfa in Ontario. The adult alfalfa weevil overwinters as a 4 - 5 mm (3/16 inch) brown snout beetle. Since the 1950's, when the weevil was introduced to this part of North America with devastating results, over a dozen parasitoids and predators have been released to control the weevil. www.omafra.gov.on.ca /english/crops/facts/alfalfa_weevil.htm   (1274 words)

L-5362 Controlling the Pecan Weevil Pecan weevils, which also feed on all species of North American hickory, can be found from New York to Iowa, south to Oklahoma, and across the southeastern states from Florida to west Texas. The emergence of adult pecan weevil is directly related to the type of soil and soil moisture conditions. The pecan weevil is an insidious pest that infests nuts that could otherwise be harvested and used as food. insects.tamu.edu /extension/bulletins/l-5362.html   (2585 words)

Practical Black Vine Weevil Management Since the inside of the unopened truck is dark, adult weevils wander out of their hiding places into the artificial "nocturnal" environment, and may be visible on the inside of the truck. In fact, it is plausible that control of root weevils in the nursery with either bifenthrin or nematodes may provide continued benefit in protecting these plants after their installation in the landscape. Permitting a few weevils to feed on the foliage should not jeopardize the health of established plants, and a small amount of weevil feeding is a sign that the landscape has a healthy, multi-layered ecosystem, complete with prey and predators. www.rhododendron.org /v57n4p219.htm   (2978 words)

Sunflower Seed Weevil Management Growers should start counting adult red sunflower seed weevils when more than half of the plants in the field are in the stage of just showing yellow ray petals (R5.0) to 30 percent of the head shedding pollen (R5.3) and the rest of the plants in the field are still in the bud stage. Although insecticides applied to sunflower at the bud stage will kill weevils, treatments at that stage are not economical or effective because (1) seeds have not developed to a stage suitable for oviposition, (2) eggs within the weevil are not mature, and (3) adult weevil emergence is still continuing. Also, the gray sunflower seed weevil does not lay as many eggs as the red sunflower seed weevil, so the economic threshold for the gray is higher than for the red sunflower seed weevil. www.ag.ndsu.edu /pubs/plantsci/rowcrops/e817w.htm   (3156 words)

History of the Boll Weevil Eradication Program With Congressional leadership and support, a USDA Boll Weevil Research Lab was created followed by eradication experiments, a trial eradication program and an areawide boll weevil control program on Texas' High Plains and Rolling Plains to prevent the weevil's migration. The goal is to eradicate the weevil as an economic pest from the U.S. during this decade. The weevil is still costing growers about $300 million annually, mostly in the Mid-South and in Texas, Oklahoma and New Mexico where eradication programs are either underway or about to be launched. www.cotton.org /tech/pest/bollweevil/eradication2.cfm   (428 words)

Black Vine Weevil, HYG-2016-95 All of these weevils are collectively called root weevils because their larvae feed on a variety of plant roots. The weevils hide during the daytime at the base of plants or in mulch and leaf litter near food plants. These weevils are difficult to control once established because of their nocturnal behavior, the subterranean habits of the larvae, and the lack of natural predators or parasites. ohioline.osu.edu /hyg-fact/2000/2016.html   (1238 words)

We Don't Cotton to Boll Weevil ‘Round Here Anymore   (Site not responding. Last check: 2007-10-13) Agricultural Research Service boll weevil scientists have almost succeeded in working themselves out of a mission in the best possible way—by having helped to create a program that is closing in on its goal of eradicating the boll weevil from the United States. Hope for stopping the boll weevil in its beetle tracks was relatively bleak until the 1970s, when research by ARS and universities like Texas AandM, Louisiana State University, Mississippi State University, and others evolved into a complex of tools that had the potential to remove this foreign invader from the country. The boll weevil eradication program depends primarily on detection and carefully targeted insecticide use, unlike the screwworm program to which it is often compared but which depended on biological control—releasing sterile male insects to prevent reproduction. www.ars.usda.gov /is/AR/archive/feb03/boll0203.htm   (2541 words)

pepper weevil - Anthonomus eugenii Cano Pepper weevil was first found in the United States in Texas, in 1904, reaching California in 1923 and Florida in 1935. Pepper weevil populations persist only where food plants are available throughout the year, largely limiting its economic pest status to the southernmost state in the USA. This weevil, though a serious pest in Brazil and other areas of Latin America, is still quite limited in distribution in the United States. creatures.ifas.ufl.edu /veg/beetle/pepper_weevil.htm   (1600 words)

Boll Weevil Monument   (Site not responding. Last check: 2007-10-13) The Boll Weevil Monument is located in Enterprise, Alabama, at the corner of College and Main Streets.

Boll weevil eradication effort Before boll weevil eradication efforts were initiated, growers in the Hill regions spent approximately twenty to twenty-five dollars per acre on boll weevil control and still suffered yield losses each year. This means that by approaching boll weevil control in an organized manner, through their boll weevil eradication program, growers in these areas were able to obtain much better control of boll weevils at a cost similar to what they would have had in the absence of an eradication program. By continuing to monitor every cotton field for boll weevils, reinfestations can be detected early, before they have a chance to spread, and eliminated at a cost of a few thousand dollars, rather than the millions of dollars that would be required if a large area became reinfested. deltafarmpress.com /mag/farming_boll_weevil_eradication_4   (1401 words)

Boll weevil - Wikipedia, the free encyclopedia The boll weevil (Anthonomus grandis) is a beetle measuring an average length of six millimeters (¼ inch). The boll weevil contributed to the economic woes of Southern farmers during the 1920s, a situation exacerbated by the Great Depression. Between 1996 and 2000, the minor league baseball team in Kannapolis, North Carolina was called the Piedmont Boll Weevils, a nod to the city's heritage as a textile mill town. en.wikipedia.org /wiki/Boll_weevil   (832 words)
