(wikipedia.org)
  • Once they are ready to pupate, the grubs spin reddish-brown cocoons in one of the main mining halls they created as larvae. (wikipedia.org)
  • soil

  • insects
  • Care should be taken while looking for seed weevils not to confuse other insects which may be present on sunflower heads, such as minute pirate bugs ( Figure 1 ), for seed weevils. (gov.mb.ca)
  • Traditionally several ethnic groups in Indonesia are known to consume insects-especially grasshopper, cricket, termite, also the larvae of sago palm weevil and bee. (wikipedia.org)
  • seeds
  • Because most seeds are only partially fed upon, it is difficult to separate healthy from weevil-damaged seed. (gov.mb.ca)

  • Seeds infested by this larvae enlarge, protruding above the surrounding seeds, and lack a kernel. (gov.mb.ca)
  • Adult bean weevils hibernate inside the seeds or seed pods of these plants. (wikipedia.org)
  • It damages crops both in situ and when stored in warehouses, and can potentially reduce crop yields by 60% as the larvae develop at the expense of the seeds. (wikipedia.org)
  • Wasp
  • The female wasp hunts for weevil larvae which are immobilised by stinging and by chewing. (wikipedia.org)

  • pods
  • These grub-like larvae do take on the C-shape form and tend to attack the fruit and pods of the solanaceae (nightshade) family, such as pepper, tomato, eggplant and petunia plants. (ehow.com)
  • foliage
  • The larvae tend to attack the roots of turf grass but also may climb to the tops of flowers and herbs in your garden and eat the foliage. (ehow.com)
  • While these weevils do harm foliage they shouldn't affect the overall health and longevity of established trees. (wikipedia.org)
  • grown
  • In sunflowers grown for oil, the threshold is ten to 12 weevils per plant. (gov.mb.ca)
  • In sunflowers grown for confection, the threshold is one to two weevils per plant. (gov.mb.ca)
  • The full grown larvae are 14-16 mm (0.55-0.63 in), typical for weevils, apodial, curved and are whitish, with brown head. (wikipedia.org)
  • kills

  • In the laboratory, the nymphs have fed on larvae of the greater wax moth (Galleria mellonella), several stages of the Mexican bean beetle (Epilachna varivestis), larvae of tobacco budworm (Heliothis virescens) and larvae of black cutworms (Agrotis ipsilon). (wikipedia.org)
  • spray
  • For accurate checking of individual sunflower heads, brush the face of the heads vigorously in order to bring the weevils to the surface or spray mosquito repellent containing DEET on the head. (gov.mb.ca)
  • Alfalfa growers who find sick weevils should not spray. (chillicothenews.com)
  • evidence

  • plants
  • Count the number of weevils on 5 plants at each site for a total of 25 plants. (gov.mb.ca)
  • The large pine weevils have a tendency to attack artificially fertilized trees, especially those fertilized with phosphorus which causes greater nutritional quality of phloem for the weevils or make faster more attractive plants for the weevils due to faster growing. (wikipedia.org)
  • Bean weevils feed on vetches, beans and other leguminous plants. (wikipedia.org)
  • Bean weevils develop and feed upon leguminous plants. (wikipedia.org)
  • grain
