Illustrated Redescription of Sugarcane Black Bug Cavelerius sweeti Slater and Miyamoto with Notes on Population Dynamics from Bihar
Black bugs of the genus Cavelerius (Lygaeoidea: Blissidae) are known pests of sugarcane in many parts of South-East Asia. Species Cavelerius sweeti Slater and Miyamoto, 1963, found in Pusa, Bihar, is redescribed here in detail with several digital images. The DNA was extracted and mitochondrial cytochrome oxidase subunit 1 gene was amplified and sequenced. The obtained sequence was compared with other members of Blissidae. Cavelerius sweeti and Cavelerius saccharivorous were clustered together and the other cluster comprised of sister species Cavelerius yuanensis and Cavelerius excavatus. Cavelerius sweeti was 7% divergenet from its sister species Cavelerius saccharivorous. Seasonal population dynamics of this pest in sugarcane plant crop revealed peak population during 20th (5.1 black bugs/plant) and 24th (7.1 black bugs/plant) SMW during the years 2021–22 and 2022–23, respectively. In ratoon crop, the infestation was more severe than plant crop and the peak was observed during the 18th (19.6 black bugs/plant) and 24th (19.8 black bugs/plant) SMW during the same years.
期刊介绍：
The journal Sugar Tech is planned with every aim and objectives to provide a high-profile and updated research publications, comments and reviews on the most innovative, original and rigorous development in agriculture technologies for better crop improvement and production of sugar crops (sugarcane, sugar beet, sweet sorghum, Stevia, palm sugar, etc), sugar processing, bioethanol production, bioenergy, value addition and by-products. Inter-disciplinary studies of fundamental problems on the subjects are also given high priority. Thus, in addition to its full length and short papers on original research, the journal also covers regular feature articles, reviews, comments, scientific correspondence, etc.
