GreenLight Biosciences Launches Norroa: A New Era for Beekeeping

In an important development for agriculture and environmental sustainability, GreenLight Biosciences has received approval from the U.S. Environmental Protection Agency (EPA) for Norroa™, the world's first RNA-based treatment targeted at controlling varroa mites, which are notorious for ravaging honey bee populations. This groundbreaking solution is particularly significant as the agricultural landscape faces unprecedented challenges due to declining bee health and colony losses.

The Varroa Mite Crisis

Recent statistics illuminate a critical situation. The Honey Bee Health Coalition reports a staggering 1.7 million honey bee colonies were lost, equating to an average 62% loss among commercial beekeepers between June 2024 and March 2025. This trend has prompted alarm among entomologists and agricultural experts alike. They warn that without significant intervention, such as innovative treatments like Norroa, these losses could escalate to a shocking 70% in the coming year.

The varroa mite, a parasitic arachnid, attaches itself to bees and can reproduce quickly, leading to a cycle of damage and disease within colonies. Traditional chemical miticides are becoming increasingly ineffective as the mites evolve resistance, leading to higher virus loads within the bee populations.

Norroa's Innovative Approach

Norroa is designed to provide beekeepers with a new, environmentally sustainable option to combat varroa mites. Its active ingredient, vadescana, utilizes RNA interference (RNAi), a natural biological process that targets the reproductive capabilities of the mites. This ensures that the treatment is both specific and efficient, reducing the need for harsher chemicals that may harm beneficial insects and the surrounding ecosystem.

GreenLight Biosciences CEO Andrey Zarur emphasized the importance of this product, stating, “Norroa offers a significant advancement for beekeepers in the fight against one of their most formidable foes.” He praised the EPA's thorough examination of this cutting-edge, American-made technology, which aligns with sustainable agricultural practices. The rapid breakdown of vadescana in the environment further enhances Norroa's safety profile, making it a responsible choice for beekeepers.

Proven Efficacy

Extensive field trials across various U.S. regions have demonstrated the effectiveness of Norroa, showing prolongation of mite control for as much as 18 weeks. This evidence suggests that not only does Norroa help maintain healthy bee populations, but it increases the chances of colonies surviving harsh winter conditions, a critical factor for beekeeping success.

Jason Miller, a fifth-generation beekeeper, shared his insights: “I’ve seen firsthand how devastating varroa mites can be. Norroa offers an effective, environmentally responsible alternative that is vital for our operations and the nation's food supply.”

Looking Ahead

As beekeepers adjust to the decreasing efficacy of traditional treatments, Norroa represents a beacon of hope. Mark Singleton, Chief Commercial Officer at GreenLight Bio, noted the urgency among beekeepers for alternatives to mitigate the risks posed by varroa mites. He described Norroa as a “breakthrough” solution that promises extended mite control and ease of use.

This launch is not just a win for beekeepers; it stands as a pivotal moment in the quest to safeguard honey bee populations that play a crucial role in pollinating crops worth over $20 billion annually in the U.S. With Norroa exclusively available through Mann Lake Ltd. and their network, this innovative treatment could significantly transform the landscape of beekeeping.
