摘要
为优化中华通草蛉室内饲养技术和室内种群复壮,研究了不同植物来源的蜂花粉对中华通草蛉繁殖力及子代种群增长的影响。结果表明:中华通草蛉成虫取食茶花蜂花粉后产卵前期延长至6.00 d,平均单雌产卵总量达到228.30粒,与对照相比(5.00 d和113.90粒)显著增加。取食玉米蜂花粉时,单雌产卵总量平均为216.10粒,与茶花蜂花粉处理差异不显著,但显著高于对照组。而油菜蜂花粉处理则导致雌成虫寿命显著缩短至12.20 d。在子代生长发育方面,三种蜂花粉处理下子代幼虫发育历期均显著缩短,且茶花和玉米蜂花粉处理下的子代茧重显著大于油菜蜂花粉处理。同时,茶花和玉米蜂花粉显著提升子代成虫的产卵总量和寿命。其中,单雌产卵总量由对照的116.80粒分别增加至275.70粒和253.40粒,而雌成虫寿命则由20.45 d延长至23.35 d和25.70 d。此外,茶花和玉米蜂花粉处理后,子代种群的净繁殖率(R_(0))由对照的29.63显著增加至63.42和61.35,内禀增长力(r_(m))和周限增长率(λ)则由对照的0.09、1.10增加至0.12、1.12和0.11、1.12,而种群加倍时间(D_(t))则分别为5.94 d和6.08 d,显著短于对照组7.25 d。综上所述,中华通草蛉成虫期取食玉米蜂花粉和茶花蜂花粉可以促进其生殖力和子代种群增长。研究结果为提升中华通草蛉室内扩繁效率提供了科学依据。
This study examined the impact of different bee pollens on reproductive fitness and offspring population dynamics of Chrysoperla sinica.Results showed that feeding on camellia bee pollen extended the pre-oviposition period of C.sinica adults to 6.00 days and significantly increased the total number of eggs laid to 228.30 per female,compared with the control group(5.00 days and 113.90 eggs).Corn bee pollen led to an average of 216.10 eggs per female,not significantly different from camellia bee pollen,but higher than the control group.However,rape bee pollen reduced female adults’longevity to 12.20 d.All three treatments shortened the larval duration of the offspring significantly.Cocoon weight under camellia and corn bee pollen treatments was significantly higher than that of rape bee pollen treatment.In addition,camellia and corn bee pollen significantly improved the fecundity and longevity of offspring adults.Specifically,the total number of eggs laid per female increased from 116.80 in the control group to 275.70 and 253.40,respectively,while the longevity of female adults was extended from 20.45 d to 23.35 d and 25.70 d,respectively.After being treated with camellia and corn bee pollen,the net reproductive rate(R_(0))of the offspring population significantly increased from 29.63 in the control group to 63.42 and 61.35,respectively.Meanwhile,intrinsic rate of increase(r_(m))and finite rate of increase(λ)also exhibited notable enhancements,rising from 0.09 and 1.10 in the control group to 0.12,1.12,and 0.11,1.12,respectively.The population doubling time(D_(t))was significantly shortened to 5.94 d and 6.08 d,respectively,compared with the control group(7.25 d).In conclusion,feeding C.sinica adults with corn bee pollen and camellia bee pollen can promote their fecundity and offspring population growth.These findings provide scientific basis for improving the indoor breeding efficiency of C.sinica.
