Tessaratoma javanica (Thunberg) (Hemiptera: Tessaratomidae) an important sucking pest of litchi is studied for supplementing information on its biology, morphometrics of life stages and mtCOI (DNA barcodes). More details generated on the study add to the description of stages namely egg, 1st to 5th nymphal instars and adults. The evaluation of morphometrics of the life stages reveal that the progression of growth is more during 2nd to 3rd nymphal stages, and these are critical as far as the growth and development is concerned. The life cycle takes about 141.7±4.25 days; eggs last for 12.81±1.4 days with 97.14±2.86% hatchability; and duration of 1st , 2nd, 3rd, 4th and 5th nymphal instars were 11.69±0.58, 7.23±0.2, 8.63±0.55, 13.04±0.55 and 26.31±0.97 days, respectively. In addition mtCOI analyses have been done employing standard 658 bp barcode fragments facilitating molecular diagnostics of the adults and other life stages and the phylogenetic tree with available sequence in the GenBank.
爪哇巨蝽（Tessaratoma javanica (Thunberg)）（半翅目：巨蝽科）是荔枝的一种重要刺吸式害虫，本研究旨在补充其生物学、各虫态形态测量学以及线粒体细胞色素氧化酶亚基I（mtCOI，DNA条形码）方面的信息。该研究产生的更多细节补充了卵、1至5龄若虫和成虫等虫态的描述。对各虫态形态测量学的评估表明，若虫第2至3龄阶段的生长进程更快，就生长发育而言，这些阶段至关重要。其生命周期约为141.7±4.25天；卵期持续12.81±1.4天，孵化率为97.14±2.86%；1龄、2龄、3龄、4龄和5龄若虫的历期分别为11.69±0.58天、7.23±0.2天、8.63±0.55天、13.04±0.55天和26.31±0.97天。此外，已采用标准的658 bp条形码片段进行mtCOI分析，这有助于对成虫和其他虫态进行分子诊断，并构建了包含GenBank中可用序列的系统发育树。
