Abstract

First report of the Indian date palm leaf miner, Javeta pallida Baly (Coleoptera: Chrysomelidae: Cassidinae: Coelaenomenoderini), on pygmy date palm, Phoenix roebelenii O'Brien (Arecaceae).

Abstract

Heavy infestations of Javeta pallida on five pygmy date palms (Phoenix roebelenii) were observed in Calicut, Kerala, India. During March-April 2016, 86-100% of fully opened fronds were infested. All life stages were observed on the plants. Two fronds from each of the bottom, middle, and top of the crown of each plant were randomly selected. The leaf mines per leaflet were counted, and the percentage of infested leaflets was calculated. The percentages of leaflet infestation in the bottom, middle and top fronds were 11-98%, 16-98% and 1-77%, respectively. The difference in extent of infestation on the top fronds compared to lower ormiddle fronds was not statistically significant. This is the first report of J. pallida on P. roebelenii in India.
