Abstract:
Plodia interpunctella (hubner) the Indian meal moth was used in this research. İn our study were examined effects of photoperiod and nutrient variety on the preadult developmental time of Plodia interpunctella. Experiments were carried out in laboratory conditions with the temperature of 26 ± 1 ᵒ C and 60% moisture proportion. Corn flour and bran were used for P. interpuncella as nutrient. For the photoperiods, five photoperiods were studied as following; CD (continuous daylight), CD (continuous darkness), 18L:6D (18 hours of daylight, 6 hours of darkness) 12L:12D (12 hours of daylight, 12 hours of darkness) 6L:18D (6 hours of daylight, 18 hours of darkness) regimes.. In our study, shortest preadult developmental time is in CL photoperiod condition. we found developmental time of the Indian meal moth was significantly influenced by the different diets and photoperiod. P. İnterpunctella develop fastest as pre-adults under CLcycles compared to short day lengths corn flour is the most efficient nutrient compared to all conditions. As the daylight period increases, preadult developmental time decreases. As the daylight increases at different photoperiods, development period become shorter. Development of both nutritient was fastest under CL cycles.
