摘要

The use of a double-sided self-adhesive tape for pollen trapping could offer some advantages over traditional adhesives, manually applied to the Melinex tape of a Hirst-type spore trap, since variation in terms of adhesive application is nil and additional effort in applying the adhesive is avoided. Nevertheless, its efficiency with respect to the standard adhesives must be tested. In Cordoba (southwest Spain), the Spanish Aerobiology Network Centre performed a series of comparative studies and recommended the use of a silicone fluid as an adhesive. This paper compares the efficiency of a double-sided self-adhesive tape (3M) with silicone fluid as adhesive. Sampling was carried out using a Hirst type 7-day spore trap located 15 m above ground level. A Melinex tape coated with silicone fluid covered one half of the weekly drum; the other half was covered with 3M tape that included the adhesive. It is widely reported that the physical characteristics of silicone fluid do not vary with temperature (Galan and Dommguez-Vilches, 1997), but this study showed that 3M efficiency did vary with temperature. The results revealed that 3M tape was less efficacious at low temperatures, while at high temperatures it becomes stickier. In contrast, silicone fluid does not vary with temperature. The efficiency of 3M tape also seems to be negatively influenced by rain.
