MANAGEMENT OF WHITEFLIES IN BEANS

1 comment

 

      INTRODUCTION:-

  • Beans are the most adapted and commonly eaten foods throughout the world.
  • Beans are a summer crop that needs warm temperatures to grow.
  • These economical foods have the potential to improve the diet quality and long-term health of those who consume beans.
  • A legume plant produces seeds in a pod. When pods mature, they turn yellow and dry up.

         

 The various beans cultivated in India particularly in home gardens and       some commercially are as follows:

  1. French beans (Phaseolus vulgaris)
  2. Cow pea (Vigna sinensis)
  3. Cluster bean (Cyamopsis tetragonoloba)
  4. Broad bean (Vicia faba)
  5. Lima bean (Phaseolus lunatus)
  6. Soya bean (Glycine max)
  7. Garden beans (Dolichos lab lab).

    Whiteflies in beans

  

  • Whitefly, Bemisia tabaci (Gennadius) Adults are soft-bodied, moth-like fly, yellowish dusted with white waxy powder and 1.0- 1.5 mm in length.
  • The females prefer hairy leaf surfaces to lay more eggs, they mostly lay eggs near the veins on the underside of leaves.
  • Upon hatching the nymph moves on the leaf surface to locate a suitable feeding site.
  • The wings are covered with powdery wax and the body is light yellow in color.
  • Both adults and nymphs suck plant sap and reduce vigor of the plant.
  • When the population is high they secrete large quantities of honeydew, which favors the growth of sooty mould.
  • Whiteflies are tiny white flying insects that congregate on the undersides of pole bean leaves.

 Symptoms of Whiteflies in beans 

  •    An easy way to detect the insects is to give the pole bean plant a gentle shake.
  • When whiteflies are present, they rise in a cloud above the foliage.
  • Whitefly nymphs are sometimes too tiny to see, even with a hand lens.
  • Whiteflies feed on pole beans in many vegetable gardens and sometimes go unnoticed when populations are low.
  • The insects are hard to detect because they are so small; however, when populations increase, it is almost impossible not to notice the clouds of tiny insects and the damage they cause.
  • You can safely ignore small populations, but large populations result in substantial damage to the leaves and crop loss.
