“…Like other agricultural plants, sweet basil is vulnerable to being infected with various species of insects, causing substantial losses (Golan et al 2019). Piercing-sucking insects are among the insect pests that exert noticeable damage to sweet basil plants (Ismail 2006, El-Ghanam 2017, Osman et al 2017, Abou El-Saad 2018, Kumar et al 2022. Whiteflies, cotton aphids, plant bugs, leafhoppers, and thrips are the most abundant and destructive insects on sweet basil (Sathe et al 2014, Namvong and Chongrattanameteekul, 2015, Abou El-Saad 2018.…”

Piercing-sucking insects are notorious devastating insects that cause substantial damage to crops and yield losses due to the direct feeding by both nymphs and adults furthermore through the transmission of viruses and diseases. Field experiments were conducted during the two growing summer seasons of 2021 and 2022 at Zagazig district, Sharkia Governorate, Egypt to assess the seasonal abundance of the major piercing-sucking insects and their associated natural enemies on sweet basil plants. Five piercing-sucking insect species were surveyed; Bemisia tabaci (Genn.), Aphis gossypii Glover, Nezara viridula L., Empoasca decipiens (Paoli), and Thrips tabaci Lind. Also, six predatory species were recorded; Coccinella undecimpunctata L., Chrysoperla carnea (Steph.), Orius sp., Paederus alfierii (Koch), Metasyrphus corollae (Fabr.) and Scymnus sp., and three parasitoid species were observed; Aphidius colemani (Viereck) as a primary parasitoid, Alloxysta sp. as a hyperparasitoid on A. gossypii and Trissolcus megalocephalus (Ashmead) as a parasitoid of N. viridula eggs. Our observations about the main piercing-insects and their natural enemies on sweet basil could be considered as a part of their control plan.
