摘要

Bitter gourd is a prominent vegetable known for its nutritional and medicinal value. However, various factors contribute to its lower production, including attacks by several pests such as the red pumpkin beetle, fruit fly, jassids, aphids, and whitefly, affecting different stages (seedling, vegetative, and reproductive) and parts (stem, leaves, flowers, and fruits) of the plant. Arthropod collections were conducted weekly from February to July 2023 across four bitter gourd field locations in Tamil Nadu using various sampling techniques, including sweep nets, traps, and active searching. 12,481 individual arthropods belonging to 80 species from 45 families, 74 genera, and 10 orders, were documented in the bitter gourd ecosystem across two classes (Insecta and Arachnida). The order Coleoptera was the most diverse, with 22 species from 8 families, followed by Hymenoptera with 15 species from eight families, Lepidoptera (10 species, 4 families), Hemiptera (9 species, 7 families), Diptera (8 species, 8 families), Odonata (5 species, 2 families), Orthoptera (3 species, 2 families), Mantodea (2 species, 1 family), and Thysanoptera (1 species, 1 family). Additionally, 5 spider species from 5 genera and 4 families were recorded. Among the arthropods, predators represented the largest group with 34 species, followed by pests (22 species), pollinators (19 species), parasitoids (2 species), and tourists (3 species). The highest species diversity and richness were recorded in Narasipuram, with a Shannon-Weiner diversity index of 3.268, followed by TNAU Orchard (3.182), and Thondamuthur (2.914). Pollachi exhibited the lowest diversity (2.681).
