Hoverfly locomotor activity is resilient to external influence and intrinsic factors

摘要: Hoverflies are found across the globe, with approximately 6000 species described worldwide. Many hoverflies being used in agriculture and some emerging as model for laboratory experiments. As such it is valuable to know more about their activity. Like many other dipteran flies, Eristalis have been suggested be strongly diurnal, but this based on qualitative visualization by human observers. To quantify how hoverfly activity depends internal external factors, we here utilize a locomotor monitoring system. We show that active during entire light period when exposed 12 h light:12 dark cycle, lower if night. hoverflies' stable over lifetime does not depend diet provided. Surprisingly, find no difference between males females, significantly affected sex of an accompanying conspecific. Finally, female resilient starvation than males. In summary, range supporting use long-term
