Abstract Context Understanding the movement of bioaerosols, such as spores and pollen, through atmosphere is important for a broad spectrum landscape research, including agricultural fungal outbreaks pollen threats to public health. As can be transported in air over large distances, use aircraft has historically played role detecting mapping their presence lower atmosphere. Objectives We present simple alternative costly specialized associated equipment that are typically used study Methods 3D printable components common lab supplies mounted on an uncrewed (UA). Conveniently, this setup does not require additional electronic control collection during flight, using UA landing gear mechanism instead. Results demonstrate apparatus collect describe potential impacts by environment experimental protocol efficiency. These include effects of: (1) competing airflows from rotors, flight trajectories, wind, (2) altitude, (3) particle size Petri dish medium.
