Ovipositional decisions in herbivorous insects may be affected by social information from conspecifics. Social facilitation of oviposition has been suggested for the onion fly Delia antiqua. In the current study, we found that D. antiqua oviposition was unequal between paired oviposition stations of equal quality and that more eggs were laid on an oviposition station baited with decoy flies than on the control. The increased oviposition toward the decoys continued over time >8 h. When decoys were placed upside down, the number of eggs laid did not differ between the decoy and control sides of oviposition stations, suggesting that social facilitation of oviposition is mediated by visual cues. Based on these findings, mechanisms of social facilitation of oviposition in D. antiqua were discussed.

洋葱蝇 Delia antiqua (Diptera: Anthomyiidae) 的产卵在社会上受到视觉线索的促进

草食性昆虫的产卵决定可能会受到来自同种的社会信息的影响。有人建议洋葱蝇产卵的社会促进作用迪莉娅古董. 在目前的研究中,我们发现D. 古董相同质量的成对产卵站之间的产卵量是不相等的,并且在用诱饵苍蝇诱饵的产卵站上产的卵比在对照上的多。随着时间的推移> 8 小时,诱饵的产卵量增加。当诱饵被倒置时,产卵站的诱饵和对照侧的产卵数量没有差异,这表明产卵的社会促进是由视觉线索介导的。基于这些发现,社会促进产卵的机制D. 古董进行了讨论。
