Özet

In the trials, the influence of photoperiod on the development time, sex ratio,and fecundity of Acanthoscelides obtectus were examined. The trials werecarried out in five different photoperiod regimes including 0L:24D [continuousdarkness (CD)], 6L:18D (6 hours of light, 18 hours of dark), 12L:12D (12 hoursof light, 12 hours of dark), 18L:6D (18 hours of light, 6 hours of dark), 24L:0D[continuous light (CL)] with a temperature of 25±2 ºC and 60±5% relativehumidity. The shortest pre-adult development time was determined under CDconditions. While the development period lasted 26.33±0.88 days under CDconditions, it lasted for 35.33±0.66 days under CL conditions. Although thesex ratio did not differ much, CL conditions were in favor of males. The lowestfemale fecundity was determined under CL and 18L:6D conditions. Fecunditydid not differ significantly under CD and 6L:18D, while it decreased significantlyunder 12L:12D, 18L:6D, and CL conditions. Especially, when CL and CD werecompared with each other, statistically significant difference was observed.
