Faunistic Survey and New Records of Cicadellidae (Hemiptera) Species on Grapevine in Semi-Arid Regions

Abstract

Faunistic survey and new records of Cicadellidae (Hemiptera) species on grapevine in semi-arid regions were conducted to document species diversity, distribution patterns, and potential new host associations. Field sampling was carried out in major grape-growing semi-arid zones, and leafhopper populations were collected using sweep netting, yellow sticky traps, and direct leaf examination. Specimens were identified based on external morphological characters including head shape, wing venation, coloration patterns, and male genitalia structures using standard taxonomic keys. Results revealed a diverse assemblage of cicadellid species associated with grapevine, including several taxa previously unreported from the surveyed regions, indicating new distributional records. Species composition varied across locations, influenced by climatic conditions, vineyard management practices, and surrounding vegetation diversity. Higher abundance was observed during warm and dry periods, which favored rapid population buildup and dispersal. Certain species showed strong host association with grapevine, while others appeared as occasional or transient visitors from surrounding vegetation. The faunistic analysis highlights the ecological adaptability of Cicadellidae in semi-arid agroecosystems and their potential role in grapevine health, including direct feeding damage and possible vectoring of plant pathogens. The study emphasizes the importance of continuous monitoring to update regional biodiversity records and assess pest risk in grape production systems.
