  • Historical weather data were used to divide the northern United States into five climatic zones based on the number of hours below 15.6°C (60°F), which is the approximate lower developmental threshold for the maize weevil, Sitophilus zeamais Motschulsky, during a calendar year. (uky.edu)
  • A model for population growth and development of the maize weevil, which is integrated with a bin-cooling model, was used to predict temperature, relative humidity, number of larvae, and number of adults in unaerated and aerated corn during 1 yr of storage. (uky.edu)
Quarantine2
  • Fortunately, rearing is relatively easy, and so CABI was able to send hundreds of M. borraginis to a quarantine laboratory at the University of Idaho led by Prof Mark Schwarzländer, to conduct research on the chemical ecology of the weevil affirming its environmental safety. (cabi.org)
  • In the meantime, we are maintaining colonies of the weevil at CABI and in quarantine in the USA, so that we will be ready to release it when all the necessary checks and approvals have been done and granted. (cabi.org)
Parasitic1
  • The parasitic wasp Catolaccus hunteri (Crawford) is the most abundant parasitoid attacking the pepper weevil in Florida. (greenhousecanada.com)
20162
  • The sticky traps were assessed for the incidence of pepper weevil adults (Figure 3) on a weekly basis from May 13, 2016 to October 21, 2016 (last harvest) for a total of 23 weeks. (calpeppers.com)
  • Pepper weevil was first detected on May 27th, 2016. (calpeppers.com)

Grubs1
  • If you have ever picked up pecans that had a hole in the top of the shell and were empty or found grubs inside pecans when you cracked them open, then you have experienced pecan weevils. (ncsu.edu)
Damage12
  • Pecan weevils damage nuts in two ways. (ncsu.edu)
  • Weevil damage increases the longer the crop remains not harvested. (infonet-biovision.org)
  • Damage by weevils can be recognised by the holes in the vines or the tunnels in the tuber when you pull them up from the soil. (infonet-biovision.org)
  • The use of pitfall traps may be sufficient for surveying emerging adults or periodically checking the plant for recent leaf damage and fecal droppings. (ncsu.edu)
  • Rose weevils damage to roses in several different ways. (tripod.com)
  • First the weevils damage roses by making feeding punctures with their long beaks on rose buds, calyx, and peduncle. (tripod.com)
  • The greatest damage to roses is cause when adults feed on flower buds. (tripod.com)
  • Rose weevils start to damage roses at the first sight of bud formation and they tend to prefer certain roses more than others. (tripod.com)
  • Regular handpicking of the adult weevils and removal of damaged buds and spent blossoms will prevent continuing damage and will prevent severe populations the following year. (tripod.com)
  • Carrot weevil damage has been increasing on New Jersey carrot farms during the past several years, and yield losses exceeded 75% on farms in Salem County in 2002 and 2003. (ashs.org)
  • Start managing their population right when you start seeing leaf damage. (drummersgardencenter.com)
  • Create a yard that attracts these predators so they can help you with minimizing damage and the beetle population. (drummersgardencenter.com)
Plantations1
  • In this way, the use of this trap for monitoring banana weevil in plantations of plantains in the southern region of Bahia is recommended. (academicjournals.org)
Soil2
  • Mature weevil larvae leave the flower heads and crawl into the soil to spend the winter. (osu.edu)
  • The Fuller rose beetle overwinters in the soil as larvae in most regions of the United States but has been found in the adult stage year-round in Florida. (ncsu.edu)
Oviposition1
  • Consequently, pesticide applications are directed at adults to prevent or reduce oviposition. (ashs.org)
Leaf2
  • Fuller rose beetle adult on a red maple leaf. (ncsu.edu)
  • The specimen pictured here is an adult female, probably gravid, that I spotted on the leaf of a sunflower plant here in Colorado Springs on July 28 of this year. (blogspot.com)
Attacks1
Aeneus1
  • The handiwork of the sunflower headclipping weevil ( Haplorhynchites aeneus ) is just getting underway this season on purple coneflowers ( Echinacea purpurea ) in southwest Ohio. (osu.edu)
Densities1
  • In this study we ask if O. vitiosa has acquired natural enemies in Florida, how these enemies circumvent the larvae's protective terpenoid laden exudate, and what influence one of the most common natural enemies has on O. vitiosa population densities? (usda.gov)
SAPW1
Pecans2
  • Later in the season, when mature nuts begin to fall, pick up pecans daily and discard infested nuts away from the tree to lower future weevil populations. (ncsu.edu)
  • A. Buyers in non-weevil areas are also asking for ID, and if you are coming from an infested area, they will not buy your pecans. (artesianews.com)
Ysidro1
  • Weevil populations likely established in or around San Ysidro in 2014 or earlier. (ucr.edu)
Tend2
  • Adults tend to be nocturnal, so populations will not be active or noticeable during the day. (ncsu.edu)
  • In addition, C. hunter and pepper weevil tend to occur in the same places, which is always an attribute of a good parasitoid. (greenhousecanada.com)
Traps2
  • Some farmers have expressed concerns about the lures on the traps that would lure the weevils into the fields. (rutgers.edu)
  • Prior to that date, weevils were not detected in any of the sticky traps installed in this field. (calpeppers.com)
California2
  • In my garden near Sacramento, California the weevils usually show up from early April thorough early May. (tripod.com)
  • This weevil presents an enormous threat to the ornamental and edible date palm industries in California. (ucr.edu)
Spider1
  • Two-spotted spider mite populations appear to be building in many fields this week. (umaine.edu)
Foliage2
  • Adult feeding on the foliage seldom is of importance. (infonet-biovision.org)
  • Significant populations of 10 or more scales per ½ inch of twig can result in yellowed foliage and needle drop. (rutgers.edu)
Reddish1
  • The adults, as the name implies, are moths nearly 1/2 inch long with pale gray and reddish- brown wings. (tooeleonline.com)
Colonies1
  • In the lab, colonies of adult weevils can be maintained for 2-3 months on a mixed diet of cut apples and bananas (with the skin left on), and split sugar cane. (ucr.edu)

Buds8
  • Rose weevil adults on rose buds. (tripod.com)
  • The adults drill small round holes deep into the flower buds and hips for feeding and egg-laying. (tripod.com)
  • The adult punctures the floral parts contained inside buds. (tripod.com)
  • If flower buds are not plentiful, the adult curculio may feed on the tips of new rose shoots, causing the death of terminals. (tripod.com)
  • Since the adult made holes in the buds, the peduncle (stem right below the hip) becomes weak and eventually the buds fall off. (tripod.com)
  • In the absence of buds on preferred varieties, the weevils will feed on growing tips. (tripod.com)
  • Segarra-Carmona and Pantoja, 1988), and one trap can capture as many weevils as are detected by inspecting 50 flower buds (Riley and Schuster, 1994). (calpeppers.com)
  • Strawberry bud weevil or "clipper" activity continues to be low in late fields that still have flower trusses with closed buds. (umaine.edu)
