[Structural characteristics of arthropod community in grapery]

Area of Science:

• Agricultural Entomology
• Ecology
• Biodiversity Studies

Background:

• Arthropod communities play vital roles in vineyard ecosystems, influencing pest control and plant health.
• Understanding the characteristic parameters of these communities is essential for effective vineyard management.

Purpose of the Study:

• To analyze the characteristic parameters of the overall arthropod community, as well as its phytophagous and predacious sub-communities in a vineyard setting.
• To identify the key metrics contributing to the structure and diversity of these arthropod groups.

Main Methods:

• Principal Component Analysis (PCA) was employed to analyze the collected data.
• Characteristic parameters including species number (N), Hill diversity indices (N1, N2), McIntosh index (Dmc), Shannon-Wiener diversity index (H'), and abundance (R) were assessed.

Main Results:

• The first principal component explained a significant portion of the variance for the arthropod community (66.70%), phytophagous sub-community (73.39%), and predacious sub-community (54.17%).
• For the overall arthropod community, individuals' number (N), Hill diversity indices (N1, N2), and McIntosh index (Dmc) showed the largest contributions.
• Phytophagous sub-communities were primarily influenced by N, N1, N2, and total species (S), while predacious sub-communities were characterized by N1, N2, Shannon-Wiener diversity index (H'), and abundance (R).

Conclusions:

• Hill diversity indices N1 and N2 were consistently significant contributors across the arthropod community and its sub-communities in vineyards.
• These findings highlight the importance of species diversity and abundance metrics in characterizing vineyard arthropod ecosystems.
• The study provides valuable insights for ecological monitoring and management strategies in viticulture.
