Özet

The efficacy of phosphine gas as an alternative to methyl bromide for the dried fig production in Turkey was evaluated under laboratory conditions. For this purpose, 0-24, 24-48 and 48-72 h old pupae of Carpophilus hemipterus were exposed to 200 ppm phosphine at 15, 20, 25 degrees C and 75% r.h. for 2-24 h of exposure periods. Phosphine treatments were performed in gas washing bottles of 500 mL-volume. The mortality rates for different exposure periods were subjected to probit analysis, and LT50 values were calculated. The highest LT50 value was recorded as to be 12 hours on 0-24 h-old pupae at 15 degrees C. In this research, 0-24 -hours-old pupae were the most tolerant than the others at all temperatures. Increase in temperature shortens the time needed for complete mortality. These results are of importance for developing effective treatment schedules for disinfestation of dried figs on a commercial scale.
