Some factors affecting the efficiency of sticky board traps for capturing the carrot fly, Psila rosae (Diptera: Psilidae)
Bulletin of Entomological Research 80 (2), 153-158
Abstract: The relative attractiveness of coloured sticky board traps to the carrot fly (Psila rosae (Fabricius)) is described by a model in which fly catch is related positively to the amount of light reflected from the trap in the green-yellow (550-570 nm) band of the spectrum and negatively to the amount reflected in the violet-green (390-550 nm) band. The model allows the performance of new coloured traps to be predicted solely from spectral reflectivity measurements. Similar numbers of carrot flies were caught/unit area on traps varying in size from 150 cm² to 4800 cm². Most flies were caught on traps resting on the ground. The number of flies caught was reduced by 0.84% for each cm the trap was raised above 10 cm from the ground. One-sided sticky traps angled at 45° to the vertical doubled the numbers of carrot flies caught/unit trapping area and reduced by 90% the numbers of non-target species caught.
