This study aimed to assess insect pollinator diversity in pumpkin (Cucurbita pepo L.) and evaluate the bio-efficacy of botanicals for pest management while considering their impact on pollinators. Seven pollinator species were identified, with Hymenopterans, particularly honey bees, dominating. Apis dorsata (67.40%) was the most common pollinator, followed by Apis florea (14.28%). Other pollinators included species from Halictidae, Sphecidae, Syrphidae, and Pieridae families. Among the botanicals tested, Azadirachtin seed kernel extract (5%) and leaf extract (10%) effectively managed the red pumpkin beetle (Raphidopalpa foveicollis) with minimal harm to pollinators. Post-application, pollinator activity slightly increased after three to five days. The study highlights the effectiveness of neem-based botanicals in reducing pest populations while conserving pollinators, emphasizing the value of eco-friendly pest control in promoting sustainable pumpkin farming, improving both yield and crop quality.
