| Experiment Title | Survey of coconut rugose spiralling whitefly (RSWF), Aleurodicus rugioperculatus Martin and its natural enemies in Valsad and Navsari district of South Gujarat | ||
| Research Type | Survey Work | ||
| Experiment Background | The whitefly genus Aleurodicus Douglas comprising 35 species of which only the spiralling whitefly Aleurodicus dispersus Russel was so far known to occur in India (Martin, 2008). The Rugose Spiralling Whitefly (RSWF) (Aleurodicus rugioperculatus) (Aleurodidae: Hemiptera) is described by Martin from Belize in Central America in 2004 (Martin, 2004). It invaded Florida in the United States during 2009 and Guatemala (Stocks, 2012). The RSWF is polyphagous found to feed more than 118 hosts belonging to 43 plant families of economically important crops in the United States (Francies et al., 2016). RSWF was noticed in a severe form in coconut palms (Arecales: Arecaceae) in Pollachi in Coimbatore district (TN), Kottayam district (Kerala) and other parts of the country. Both nymphs and adult whitefly suck the sap by their sucking feeding habit, siphon out coconut sap by selective feeding from the abaxial of the coconut leaflets. De-sapping by RSWF would induce stress on the palms due to removal of water and nutrients, but neither colour change nor necrosis of leaflets. Extensive feeding of the insect also leads to the excretion of honey dew which subsequently gets deposited on the upper surface of the leaves down beneath and also on other under storey crops. In case of severe attack, egg spirals could be located on leaf petiole as well as on tender coconuts. Honey dew excrement, being sweet and watery, attracts ants and encourages growth of the fungus, which causes disfigurement of leaves affecting the photosynthetic efficiency of the plant. During the year 2020, this pest has also reported in some pockets of South Gujarat and hence, there is urgent need to explore the status of RSWF under south Gujarat condition. To fill up the lacuna and imminent the knowledge on status of invasive coconut rugose spiralling whitefly (RSWF) in Valsad and Navsari district of south Gujarat, the present investigation is planned with following objectives under south Gujarat condition. | ||
