摘要

The occurrence of an exotic African whitefly Aleurolobus graminicola Bink-Moenen (Hemiptera: Aleyrodidae) on vetiver, Vetiveria zizanioides (L.) Nash (Poales: Poaceae) is reported for the first time from India. The morphological diagnostic characteristics of A. graminicola are described in detail with the help of field diagnosis and microphotographic images of slide mounted specimens of pupa and adult male. Across the locations, whitefly counts from the survey indicated a range of 73.46 -179.2 nymphs per tiller. The study also documents the natural parasitism of A. graminicola by Encarsia sp. (Hymenoptera: Aphelinidae), with parasitism levels ranging from 20 to 32%. Both the whitefly and parasitoid species were further characterized through molecular approaches by sequencing partial mitochondrial cytochrome c oxidase I (COI) gene. The sequences of A. graminicola and Encarsia sp. were submitted to the National Center for Biotechnology Information (NCBI) database for the first time under the accession numbers PV035890, PV088603 and PV055140, respectively. This record further warrants extensive survey on its distribution, host plant ranges and natural enemies to develop containment and management strategies as A. graminicola may pose a potential threat to vetiver cultivation in India.
