Abstract

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.

比哈尔邦甘蔗黑蝽（Cavelerius sweeti Slater and Miyamoto）的图解再述及种群动态注释

黑蝽属（黑蝽总科：黑蝽科）是东南亚许多地区已知的甘蔗害虫。1963年在比哈尔邦普萨发现的cavvelerius sweeti Slater和Miyamoto物种在这里用几张数字图像详细地重新描述了。提取DNA，扩增线粒体细胞色素氧化酶亚基1基因并测序。得到的序列与其他成员进行了比较。sweet Cavelerius和saccharivorous Cavelerius聚在一起，另一个聚类由姐妹种Cavelerius yuanensis和cavvelerius excavatus组成。甜牛角龙与其姊妹种食糖牛角龙有7%的分化。甘蔗植株的季节性种群动态显示，第20期（5.1只/株）和第24期（7.1只/株）分别在2021-22年和2022-23年达到高峰。青枯病的危害以青枯病为主，高峰出现在同期第18期（19.6只/株）和第24期（19.8只/株）。

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.
