The growing unpredictability of causal allergens has been ascribed partly to the prevalence of different biological entities with allergenic potential in the atmosphere. A group among the multiple aeroplankton recovered in aerobiology but mostly ignored is arthropod particles. To evaluate the concentration and distribution of these arthropod parts, an aero-sampler (Gbenga-2) placed on a 2m high location was used to collect aeroplankton at Ayetoro-Itele Ota, Southwest Nigeria from January 2015 - November 2015, straddling the wet and dry seasons. Using acetolysis method, arthropod particles were recovered from the trap solution and were analysed palynologically. Microscopic analysis revealed the recovery of 179 aeroplankton out of which 129 were arthropod related elements while fungal hyphae and some pollen constituted the remaining components. Insect legs and hairs were the most abundant while mouthparts and antennae were the least recorded. Arthropod particles were compared with meteorological parameters including rainfall, wind speed, relative humidity, and temperature. There were noticeable monthly fluctuations in the quantity of arthropod particles recovered. Statistical analysis showed significant correlations between relative humidity and insect hairs and wings; rainfall and insect legs and antennae; and temperature and wings. No significant correlation between wind speed and any arthropod particles. These results indicate that there is need for a more comprehensive investigation of these microscopic arthropod particles with respect to their allergenicity upon appropriate identification using molecular technology.
