| description | <i>Sclerodermus sichuanensis</i>, a parasitic wasp, plays a significant role in wood-boring forest pest control in China. Research has shown that the photoperiod significantly affects the development and reproduction of parasitic wasps. However, the effects of the photoperiod on <i>S. sichuanensis</i> have not yet been reported. This study investigates the impact of different photoperiods on the developmental duration and reproduction of <i>S. sichuanensis</i>. The wasps were reared under four photoperiod conditions: 0L:24D, 8L:16D, 16L:8D, and 24L:0D. The results show that increased light duration shortened the egg, larval, and pupal stages, with the total developmental period decreasing by up to 17 days. The number of offspring was highest in the 8L:16D and 16L:8D treatments, while constant light (24L:0D) led to a significant decrease in offspring numbers. The parasitism rate and pre-oviposition period were also affected by light exposure, with the longest pre-oviposition period observed in complete darkness. These findings indicate that the photoperiod plays a crucial role in regulating the development and reproductive efficiency of <i>S. sichuanensis</i>, suggesting that appropriate light conditions could enhance the efficiency of its use in pest control. |
