Sri Vijaya Puram, Mar. 6: The Department of Agriculture, South Andaman has reported the infestation of Rugose Spiraling Whitefly, mainly in coconut palms. This pest has also been observed in Arecanut, banana, guava, and solanaceous vegetables. Additionally, the incidence of mealy bugs, though currently in traces, has been noticed in papaya and ornamental crops.
The Rugose Spiraling Whitefly feeds on the underside of leaves, producing excessive honeydew on the upper leaf surface which leads to the development of sooty mould. A prolonged dry spell and decreased relative humidity could encourage further infestation.
A survey conducted by the Department’s extension functionaries indicates that the incidence of the pest is currently below the Economic Threshold Level (ETL), though some patches show slightly higher infestation levels. As the present weather condition could favour wider infestation of this pest, immediate action is being planned to prevent further spread.
To tackle the issue, a comprehensive strategy has been formulated, involving:
• Formation of a Pest Control Task Force comprising Agricultural Extension functionaries.
• Active participation of PRIs in survey, execution, and feedback.
• Field monitoring by Extension staff with PRI members and immediate reporting of pest severity.
• The Task Force will implement spraying of Azadirachtin 0.3% EC in the farmer’s field of South Andaman Zone starting from Chouldari Village w.e.f 07-03-2025.
• The spraying will be done on priority basis as per the severity of the incidence of pest attack in different patches.
In this regard, farmers of all the Zones have been urged to report pest activity promptly to the nearest Sub Depot/ Extension Functionaries/PRIs or Kisan Call Centre (03192-243434 or 1800-345-1145) on all working days. Awareness and training programs will continue to support pest management efforts.
