Domesticated squash produces fewer bee-attracting scents due to breeding, potentially harming pollination.
Domestication of squash has reduced overall floral volatile organic compounds (VOCs) that attract specialist bee pollinators, altering chemical signals bees use to find flowers, according to a study led by Penn State’s Margarita López-Uribe.
While some VOCs, like 1,4-dimethoxybenzene, remain in domesticated varieties and still attract bees, overall changes may affect pollination efficiency.
The research suggests that selective breeding for agricultural traits has unintentionally disrupted plant-pollinator interactions, highlighting the need to consider ecological impacts in crop development.
