摘要
【目的】探明暗期不同LED光转换处理对斜纹夜蛾Spodoptera litura生长发育及繁殖的影响。【方法】试验组斜纹夜蛾幼虫、蛹和成虫于暗期分别接受2种LED光转换处理,共计6个处理(分别是L_(1)、L_(2)、P_(1)、P_(2)、A_(1)和A_(2)),对照组在14L︰10D条件下培养,观察其生长发育和繁殖情况。【结果】LED光转换处理对斜纹夜蛾化蛹率无显著影响(P>0.05);P_(1)处理组的成虫羽化率(66.2%,P<0.05)显著低于L_(1)和L_(2)处理组。L_(1)处理组幼虫期(雌雄分别为15.8和16.4 d)和雌蛹期(9.8 d)显著缩短(P<0.05),P_(1)和P_(2)处理组雄蛹期(分别为11.9和11.8 d)则显著延长(P<0.05);除L_(2)处理组雌蛹外,其他试验组蛹重显著低于对照组(P<0.05);P_(2)处理组雄成虫寿命(7.5 d)显著短于对照组(12.2 d,P<0.05),A_(2)处理组产卵前期(3.4 d)显著长于L_(2)和A_(1)组(P<0.05)。L_(1)、P_(1)和P_(2)处理组单雌产卵量均显著低于对照组(1427.7粒)(P<0.05)。【结论】暗期LED光转换处理对斜纹夜蛾生长发育和繁殖均有影响,且因虫态和LED光转换处理方式不同而异。
[Objectives]To understand the effects of exposure to different LED lights on the growth,development and reproduction of Spodoptera litura.[Methods]Larvae,pupae and adults of S.litura were randomly assigned to different LED light treatment groups:L_(1),L_(2),P_(1),P_(2),A_(1)and A_(2),whereas those assigned to the control group were kept under a photoperiod of 14L□10D.[Results]Exposure to LED light had no significant effect on the pupation rate compared to the control group(P>0.05).The adult eclosion rate of the P_(1)group(66.2%)was significantly lower than that of the L_(1)and L_(2)groups(P<0.05).The L_(1)group had a significantly shorter larval(♀:15.8 d,♂:16.4 d)and female pupal,periods(9.8 d,P<0.05)than the control group.The P_(1)and P_(2)groups had a significantly longer male pupal period(11.9 and 11.8 d,respectively,P<0.05).With the exception of female pupae in L_(2)group,all treatment groups had significantly lower pupal weights(P<0.05)than the control group.Adult male longevity in the P_(2)group(7.5 d)was significantly less than that of the control group(12.2 d,P<0.05),and the pre-oviposition period of the A_(2)group(3.4 d)was significantly longer than in the L_(2)and A_(1)groups(P<0.05).Females in the L_(1),P_(1)and P_(2)groups laid fewer eggs per female than those in the control group(P<0.05).[Conclusion]Exposure to different LED lights during the scotophase has significant effects on the growth,development and reproduction of S.litura.These effects vary with developmental stage and the type of LED light.
