| Popis: | Andhra Pradesh is one of the important coconut-growing states in India with an area of 0.115 million hectares producing 1,567.60 million nuts annually. The exotic pest rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) has entered India in 2016 with first reports from Kerala and Tamil Nadu states and from Andhra Pradesh in 2017. The IPM strategies which included the installation of yellow sticky traps @12/acre, re-distribution of parasitoid Encarsia guadeloupae, foliar application of entomopathogenic fungi Isaria fumosorosea NBAIR pfu 5 (5 g/litre @1x108 spores/ml) along with the release of neuropteran predator Apertochrysa astur @600 eggs per palm resulted in successful containment of RSW in experimental plantations. An effective extension network promoting IPM strategies for RSW management resulted in a decrease in incidence and intensity from 50 to 75 percent in four major coconut-growing villages in two districts in the year 2020-21 as compared to 2019-20. However, continuous monitoring for invasive whiteflies should be done rigorously as another neotropical invasive, Bondar’s Nesting Whitefly (BNW), Paraleyrodes bondari Peracchi (Hemiptera: Aleyrodidae) was observed along with RSW in coconut plantations during surveys necessitating development of an integrated approach for all invasive whiteflies. |
