Sunn Pest - Sunn Pest Management

Sunn Pest Management

Currently, there is not a pest management strategy to control the sunn pest on a national or global scale. However, there are a number of methods that farmers can utilize to help limit the damage caused by these insects.

  1. Monitor pest populations; sunn pest populations vary from year to year in response to climatic conditions. Pest populations should be monitored annually to determine if it is necessary to spray for the insect. Keeping records of population levels is beneficial.
  2. Plant early-maturing wheat varieties and harvest early; damage is less if wheat is harvested before sunn pest reach adulthood. Growing early-maturing varieties and establishing a regional uniform planting date minimizes damage. Early harvesting methods must be developed in relation to local production methods and weather conditions.
  3. Maintain shelter belts around wheat fields. Natural enemies reduce sunn pest populations and should be encouraged. Cereal crops should not be grown on marginal lands in the foothills. These areas should remain as uncultivated habitats where flowers and grow undisturbed, providing shelter and alternative food sources, which improve survival of these beneficial insects.
  4. Use chemical insecticides only if needed.

Selective insecticides should only be used when pest populations reach economically damaging levels. Applications should be made when adults move into cereal fields. Research has been ongoing for decades to develop and improve management of the sunn pest. In 1997, scientists from ICARDA, the University of Vermont, and national agricultural researchers throughout the infested region began working together to develop a model sunn pest integrated management plan.

Famous quotes containing the words pest and/or management:

    “The pest of society is egotists. There are dull and bright, sacred and profane, coarse and fine egotists. ‘Tis a disease that, like influenza, falls on all constitutions.”
    —Ralph Waldo Emerson (1803–1882)

    “No officer should be required or permitted to take part in the management of political organizations, caucuses, conventions, or election campaigns. Their right to vote and to express their views on public questions, either orally or through the press, is not denied, provided it does not interfere with the discharge of their official duties. No assessment for political purposes on officers or subordinates should be allowed.”
    —Rutherford Birchard Hayes (1822–1893)
