Morphological and molecular confirmation of occurrence of neotropical invasive Bondar’s Nesting Whitefly, Paraleyrodes bondari Peracchi (Hemiptera, Aleyrodidae) in sugarcane and its seasonal dynamics B. Bhavani, P.K. Varma, G.V. Krishna, Ch. Mukunda Rao Journal of Environmental Biology, 2026 Aim: The present study was undertaken to identify and confirm the neotropical invasive whitefly species infesting sugarcane through morphological and molecular characterization, and to assess its seasonal incidence and associated natural enemies. Methodology: The invasive whitefly infesting the sugarcane leaves was identified and confirmed through morphological and molecular characterization. Field and laboratory studies were undertaken to document its biology, seasonal incidence in relation to prevailing weather conditions, and associated natural enemies. Results: The present study confirms the occurrence of the neotropical invasive whitefly, Bondar’s Nesting Whitefly (BNW), Paraleyrodes bondari Peracchi (Hemiptera: Aleyrodidae), on sugarcane representing the first documented report of P. bondari infesting sugarcane in Andhra Pradesh. Adults formed characteristic woolly wax nests on the underside of sugarcane leaves and exhibited oblique greyish wing bands arranged in an ‘X’ pattern. Molecular characterization of partial mitochondrial COI gene revealed 100% nucleotide identity with P. bondari sequences previously reported from coconut, and the sequence was deposited in NCBI GenBank under Accession No. PA234076.1. Interpretation: Detection of BNW on sugarcane in North Coastal Andhra Pradesh is a potential emerging threat for sugarcane cultivation due to its wide host range and rapid spread; understanding its biology and impact is essential for effective management. Key words: Bondar's nesting whitefly, Molecular characterization, Paraleyrodes bondari, Sugarcane
Identification of resistance to Sugarcane mosaic virus, Sugarcane streak mosaic virus, and Sugarcane bacilliform virus in new elite sugarcane accessions in India G. Vamsi Krishna, V. Manoj Kumar, P. Kishore Varma, B. Bhavani, G. Vijaya Kumar Frontiers in Microbiology, 2023 Sugarcane mosaic and leaf fleck diseases are significant viral diseases affecting sugarcane crops in India. The use of resistant sugarcane varieties is considered the most economical and effective approach to manage viral diseases, especially in vegetatively propagated crops such as sugarcane. Sugarcane mosaic virus (SCMV) and Sugarcane streak mosaic virus (SCSMV) are the primary pathogens responsible for mosaic disease in sugarcane-growing regions of India. Sugarcane bacilliform virus (SCBV), causing leaf fleck disease, is also often found in mixed infections with mosaic symptoms. The study aimed to identify new sources of resistance by screening sugarcane germplasm for resistance to SCMV, SCSMV, and SCBV. The screening was carried out under high inoculum using the infector row method in both plant and ratoon crops. Out of 129 genotypes tested, only 8 were found to be free of mosaic viruses, indicating a rare occurrence of resistant sources. The study revealed that mosaic disease is widespread, with nearly 95% of tested varieties/genotypes being infected with mosaic viruses. SCMV, SCSMV, and SCBV were detected in 121 out of 129 genotypes using the RT-PCR and PCR assays. Based on their response to the viruses, the tested genotypes were categorized into different resistance grades: highly resistant (grade 1), resistant (grade 2), moderately resistant (grade 3), susceptible (grade 4), and highly susceptible (grade 5). The results of the study provide valuable information about elite resistance resources that can be used for the prevention and control of mosaic disease. These resistant genotypes could also serve as potential donors for mosaic and leaf fleck disease resistance in breeding programs.
Effect of inundative releases of trichogramma chilonis in sugarcane M. VISALAKSHI, B. BHAVAN, and Journal of Biological Control, 2020 Studies on effect of inundative releases of Trichogramma chilonis in sugarcane revealed that the frequency and rate of T. chilonis release had played a significant role in the management of sugarcane shoot borers. Early shoot borer and internode borer incidence was low in T. chilonis @ 75,000/ha/release, 6 times (6.54% and 2.27% ; 3.92% and 5.85%) followed by T. chilonis @ 50,000/ha/release, 6 times (7.9% and 4.26%) whereas untreated control recorded high incidence of early shoot borer and internode borer (10.94% and 15.95 %; 5.12% and 18.25 %) during 2015 and 2016. The sustainability of inundative releases of T. chilonis with highest per cent field recovery was recorded in T. chilonis release @75,000/ha/release, 6 times during monsoon period (68.63% and 20% ) and post monsoon period (29.55% and 37.59 %) as compared to pre monsoon period (12.1% and 9.27 %) of 2015 and 2016. Cane yields recorded in plant crop, 2015 (52.42 t/ha) and ratoon crop, 2016 (47.95 t/ha) revealed that high rate of T. chilonis @ 75,000/ha/release resulted in increased yields (21.77 % and 24.64 %) over untreated control.
