Abstract
Development time and life-table parameters of Frankliniella bispinosa were determined using pollen from four plant species as food sources at 25 °C. The average length of combined larval (I + II) development was 5.47 ± 0.13 days, 4.77 ± 0.08 days, 4.88 ± 0.07 days, and 3.85 ± 0.06 days when pollen from Spanish needle (Bidens pinosa), cattail (Typha domingensis), pygmy date palm (Phoenix roebelenii), and slash pine (Pinus elliotii var. densa), respectively, were provided as food. The average length of pupal development on these pollens was 5.09 ± 0.15 days, 4.11 ± 0.13 days, 4.04 ± 0.13 days, and 4.21 ± 0.17 days. No significant difference in female longevity was observed when pollen from cattail, Spanish needle, and slash pine were provided as a single food source. When thrips were reared on cattail pollen, egg production was significantly higher than when reared on pollen from the other three species. The highest net reproductive rate (79.88 ± 12.78) and estimate of intrinsic rate of increase (0.171) were obtained when thrips were reared on cattail pollen as compared with the life-table parameters derived from the other three pollen sources.
