Experiments Hope to Bolster Nematodes’ Killer Instincts to Protect Crops
At a Glance
-
An ISS National Lab investigation from biotechnology startup Pheronym, in collaboration with the USDA, will examine how microgravity affects beneficial nematodes—tiny worms with bacteria in their gut that kill crop-harming insects.
-
A recent study found nematodes exposed to Pheronym’s patented pheromone extract were 28 percent to 78 percent more effective in controlling pecan weevils and black soldier flies than nonexposed nematodes.
-
Improving the pheromone’s efficacy could give growers a better tool to protect crops while reducing broad-spectrum chemical insecticide use.
-
In addition to benefitting crops on Earth, these environmentally safe worms could aid future crops grown in space.
