• pest
  • The rice water weevil (RWW) is occasionally an important insect pest in Missouri rice fields. (missouri.edu)
  • The foundation of this integrated management program is a thorough understanding of the biology of this important pest and its interaction with rice. (lsuagcenter.com)
  • The seasonal history of this pest in Louisiana begins in early spring, when adult weevils emigrate from their overwintering sites to rice fields. (lsuagcenter.com)
  • Plant age- and plant stage-related changes in the resistance of rice, O ryza sativa , to its most important insect pest in the US, the rice water weevil ( L issorhoptrus oryzophilus ), were investigated in a series of field and greenhouse choice and no-choice studies. (wiley.com)
  • barley
  • Keep your rice, barley, flour etc. in a cool place (if small quantities its best to keep it in the freezer). (ou.org)
  • Double bag your barley, rice & flour & keep it sealed in a zip lock bag or hard plastic container. (ou.org)
  • We recommend checking your rice & barley over a white paper plate before using it, alternatively you can soak it in water and detect if any critters float to the top. (ou.org)
  • occurs
  • The elbow occurs at the end of the scape (first antennal segment) in true weevils, and the scape is usually much longer than the other antennal segments. (wikipedia.org)
  • The yellow-poplar weevil, scientific classification Odontopus calceatus, is a type of weevil which occurs in much of the eastern and southeastern United States. (wikipedia.org)
  • eggs
  • Serious problems do not begin until the rice fields are flooded and the weevils begin to lay eggs. (lsuagcenter.com)
  • How do you destroy rice weevil eggs? (bugspray.com)
  • in Europe it has been present in Italy since 2004, in the regions of the Piedmont and Lombardy where it affects upland rice production The pearly white eggs are cylindrical (0.8 mm long and 0.14 mm long) of pearly with a very thin corion. (wikipedia.org)
  • beans
  • of beans or peas 10 lbs. of rice or hominy 10 lbs. of green coffee beans or 8 lbs. of roasted coffee beans 10 lbs. of sugar 2 qts. (wikipedia.org)
  • resistance
  • However, relying solely on insecticides to manage the rice water weevil sometimes results in unacceptable control and increases the likelihood of the development of resistance to insecticides. (lsuagcenter.com)
  • Host plant resistance has been investigated in rice but results have been less than desirable. (wikipedia.org)
  • Since the 1960s, out of 10,000 lines tested, only 2 showed moderate resistance to rice water weevil feeding. (wikipedia.org)
  • insect
  • FMC Corporation received EPA approval for use of its Fury 1.5E insecticide for broad-spectrum insect control in rice. (missouri.edu)
  • In addition, this insect has been accidentally introduced into some of the major rice-producing regions of Asia and poses a global threat to rice production. (lsuagcenter.com)
  • stages
  • Rice weevils in all stages of development can be killed by freezing infected food below -17.7 °C (0 °F) for a period of three days, or heating to 60 °C (140 °F) for a period of 15 minutes. (wikipedia.org)
  • structures
  • The loss of roots, reduces the number of plant tillers, which are the panicle bearing structures of the rice plant. (wikipedia.org)
  • Injury
  • This type of injury, although evidence of the presence of weevils in a field, usually does not result in economic losses. (lsuagcenter.com)
  • Growers
  • In the Southern US, growers use drill seeded systems that allow them to delay planting or flooding of the rice fields. (wikipedia.org)
  • Southern rice growers also use seed treatments with thiomethoxam (Cruiser) that also help In California, the best methods are treating field edges, rebuilding levees, winter flooding, and foliar spraying with pyrethroids such as lambda-cyhalothrin (Warrior) or neonicotinoids such as clothianidin (Belay). (wikipedia.org)
  • Fury
  • Since the registration of Furadan was revoked, four insecticides have been registered for use against the rice water weevil: Icon (fipronil), Karate (lambda-cyhalothrin), Fury (zeta-cypermethrin) and Dimilin (diflubenzuron). (lsuagcenter.com)
