Spotted Lanternfly Research and Development Act This bill includes combatting the spotted lanternfly (Lycorma delicatula) as a Department of Agriculture (USDA) high-priority research and extension area. The bill specifically allows grants for developing and disseminating research-based tools and treatments to combat the spotted lanternfly, which is an invasive species native to China that feeds on a wide range of crops and plants (e.g., grapes, apples, hops, walnuts, and hardwood trees). Further, the bill reauthorizes USDA grants to support competitive specialized research and extension activities, including high-priority areas, through FY2028. The bill also specifically reauthorizes through FY2028 the Pulse Crop Health Initiative; the Comprehensive Food Safety Training Network; pollinator protection research and extension grants; increased USDA capacity and infrastructure to address and conduct research on colony collapse disorder and other pollinator issues; and a USDA-conducted nationwide honey bee pest, pathogen, health, and population status surveillance program.
