Abstract

Studies on the immature nut fall in Aleurodicus rugioperculatus Martin infested coconut palms with low (<10 spirals/ leaflet), medium (10-20 spirals/ leaflet) and high (> 20 spirals/ leaflet) incidence in Dr YSRHU- Godavari Ganga hybrid and local East Coast Tall (ECT) variety were undertaken at the Dr YSRHU- Horticultural Research Station (HRS), Ambajipeta and Kalavalapalli plantations. The overall dropped nuts (%) was 4.84, 27.48 and 35.32% at Ambajipeta, while it was 5.50, 28.11 and 36.01% in Godavari Ganga hybrid palms with low, medium and high incidence during 2020-21 at Kalavalapalli. The % of dropped nuts in ECT variety with low incidence, respectively was representing the general dropping with 4.06 and 4.68% at Ambajipeta and Kalavalapalli, respectively during 2020-21. In case of ECT palms with medium and high incidence, the nut dropping was 22.33 and 28.51% (Ambajipeta), and 23.49 and 30.58% (Kalavalapalli).
