摘要
瓢虫 Cheilomenes sexmaculata 和 Propylea dissecta 是有效的生物控制剂,它们捕食蚜虫种群,从而减轻对植物的损害。这两种甲虫共存,并表现出不同的繁殖策略。以前的研究发现,雌雄异性交配现象十分普遍,并记录了异性雄性 C. sexmaculata 对雌性 P. dissecta 的生殖产量的影响。鉴于这些观察结果,我们进行了一项实验,研究异种雄性的年龄对解剖蟾蜍生殖产量的影响。这项研究涉及三个年龄组的雄性:(a)幼年(10-20 天)、(b)中期(30-40 天)和(c)老年(50-60 天)。这些雄性被引入培养皿中,与同种交配的剖腹鹦鹉一起生活。在所有实验处理中,我们考察了三种不同年龄组的 C. sexmaculata 雄性对解剖蟾蜍交配和繁殖属性的影响。我们的研究结果表明,在同种虫交配过程中,年龄较大的异种雄性比年龄较小的雄性的生殖干扰程度更高,它们的选择性降低,活动量增加。此外,在交配后与年轻的异种雄性相遇会导致雌性虫孔蛙的生殖产量下降。这项研究获得的启示对于理解在同一农田中释放多种瓢虫的可行性具有重要意义。了解物种间的相互作用及其后果对于优化害虫综合治理战略至关重要。
Heterospecific mating interference in ladybird beetles: age dependent patterns and consequences
The ladybird beetles Cheilomenes sexmaculata and Propylea dissecta serve as effective bio-control agents, preying upon aphid populations and thereby mitigating plant damage. These beetles coexist together and show different reproductive strategies. Previous studies have found prevalent heterospecific mating between C. sexmaculata male and P. dissecta female, documenting the effects of heterospecific male C. sexmaculata on the reproductive output of P. dissecta female. In light of these observations, we conducted an experiment examining the influence of heterospecific male age on the reproductive output of P. dissecta. This study involved three age groups of male: (a) young (10–20 days), (b) middle (30–40 days), and (c) old (50–60 days). These males were introduced into Petri dishes with conspecific mates of P. dissecta. Across all experimental treatments, we examined the impact of three different age cohorts of C. sexmaculata males on the mating and reproductive attributes of P. dissecta. Our findings unveiled that older heterospecific males, which displayed reduced choosiness and heightened activity, engaged in reproductive interference to a greater degree than younger C. sexmaculata males during conspecific P. dissecta mating. Further, post-mating encounters with young heterospecific males led to a reduction in the reproductive output of female P. dissecta. The insights gained from this study hold significant implications for comprehending the feasibility of releasing multiple species of ladybird beetles within the same agricultural field. Such understanding of interspecies interactions and their consequences is vital for optimizing integrated pest management strategies.
期刊介绍:
acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals.
The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics.
acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
