Recently, the Rugose Spiralling Whitefly, which attacks palms, coconuts, and bananas, has been spotted in Pune city.

About Whitefly:

  • These are winged insects that have soft bodies and are closely related to aphids.
  • These are tiny, sap-sucking insects that may become abundant in vegetable and ornamental plantings, especially during warm weather
  • It is naturally distributed in Belize, Guatemala, and Mexico (Martin, 2008), and subsequently, it has spread to 22 other countries in Central and South America.
  • It mainly infests coconut palms and other broad-leaved hosts in its native range
  • It is an invasive insect.

How the insect attacks

  • The whitefly starts attacking the lower leaves of the coconut palm.
  • It drains the sap from the underside of the leaf, producing a significant amount of honeydew, which settles on the upper surface of the next lower leaf, leading to the growth of black, sooty mould.
  • This is the secondary infection from the whitefly infestation.
  • It has a serious impact on the production of coconut.
  • Not only does it reduce the size of the coconut, but it also decreases the coconut’s water content.
