蓟马科（Thysanoptera）的许多种类的蓟马形成交配集群，但这些集群的适应意义和雄性和雌性配偶选择的程度知之甚少。我们研究了交配行为的豆花蓟马Megalurothrips sjostedti（Trybom）（Thysanoptera：蓟马科），形成男性聚集，发生在撒哈拉以南非洲。我们测试了男性是否通过女性的年龄或交配状态来选择配偶。无选择交配生物测定与一个男性和一个女性被用来模拟男性通常遇到只有一个女性在聚集在现场的时间。处女女性暴力抵制交配尝试的男性，但我们没有发现令人信服的证据来确定这是否是不分青红皂白或筛选合适的男性。较年轻的雄性（1-2天）不会因年龄（1-2或7-10天）而歧视雌性，但较年长的雄性（7-10天）避免与较年长的雌性交配。任何男性选择女性交配状态（处女或交配）是弱或缺席。本文报道了M. sjostedti与其他形成聚集的蓟马物种具有广泛的相似性，但也显示出一些独特和新颖的差异，这有助于我们理解聚集的适应意义。
Many species of thrips (Thysanoptera) in the family Thripidae form mating aggregations, but the adaptive significance of these aggregations and the extent of male and female mate choice is poorly understood. We studied the mating behaviour of the bean flower thrips Megalurothrips sjostedti (Trybom) (Thysanoptera: Thripidae), which forms male aggregations and occurs across sub-Saharan Africa. We tested whether males choose mates by female age or mating status. No-choice mating bioassays with one male and one female were used to simulate the way males usually encounter only one female at a time in aggregations in the field. Virgin females violently resisted mating attempts by males, but we found no compelling evidence to establish whether this was indiscriminate or was screening suitable males. Younger males (1–2 days old) did not discriminate females by age (1–2 or 7–10 days old), but older males (7–10 days old) avoided mating with older females. Any male choice by female mating status (virgin or mated) was weak or absent. The mating behaviour of M. sjostedti shows broad similarities with that of other thrips species that form aggregations, but also shows some distinct and novel differences, which can help our understanding of the adaptive significance of aggregations.
