Investigation on Species of Hemiptera Pests Attacking Mulberry in Guangdong and Their Damage

【Objective】In recent years, Hemiptera pests are the main pests in mulberry planting area in Guangdong, which cause great economic losses to sericulture production every year. However, there is no relevant research on the systematic identification of Hemiptera mulberry pests and damage investigation of such pests in Guangdong. Therefore, it is of great significance to systematically investigate and study the Hemiptera mulberry pests in Guangdong Province, so as to provide theoretical basis for further formulating effective control measures and carrying out relevant research. 【Method】 The investigation and identification of seven Lepidoptera pests in mulberry orchard was systematically conducted by morphology and molecular characteristics (cytochrome oxidase subunit Ⅰ gene, mtCO Ⅰ ).【Result】Seven species of Hemiptera pests were identified, i.e., Ferrisia virgata Cockerell, Anomoneura mori Schwarz, Erythroneura mori Matsumura, Aphrophora sp., Nezara viridula Linnaeus, Acanthocoris scaber Linnaeus, Dysdercus cingulatus Fabricius. Ferrisia virgata Cockerel. 【Conclusion】Among the seven identified Hemiptera pests, Aphrophora sp. and Dysdercus cingulatus Fabricius were first reported to attack mulberry in Guangdong.
