Abstract:
The first report of Bondar's Nesting Whitefly, Paraleyrodes bondari, in the Cotton environment of Tamil Nadu, India, is of its emergence and infestation. Eggs (7.7±0.16 days), I nymphal instars (3.5±0.44 days), II and III nymphal instars (7.4±0.20 days), IV instars (4.5±0.21 days), and adults (16.7±0.38 days) were the life stages recorded from egg to adult. The entire life cycle ranges is retraced. To confirm the pest, morphological and molecular taxonomic characterizations were performed. An "X"-marking on the adult forewing, as well as a little powdery covering across the wings and body. The flower-petal shaped ovoid cells on abdomen compound pores confirmed the immature stage of taxonomic character. A 658 bp COI sequence amplified and deposited in the NCBI was used for molecular confirmation at Barcode Biosciences Pvt. Ltd., Bengaluru.
