Ladybird beetles present as key predator of many agricultural pests. Among them, Eriopis connexa stands out due some important traits for pest management programs such as common occurrence, population selected for resistance to pyrethroid insecticides, and possibility to be commercially available by rearing using alternative prey. Despite that, little is known about the role of polyandry and its effect on paternity in this species. Ladybird beetles engage in multiple matings, raising questions about the benefits of polyandry and paternity. We studied the selection of mating pair, sperm precedence, and offspring paternity by performing experiments on (1) the age of sexual maturity, (2) the frequency and refractory mating behavior within a photophase period, (3) the preference of insecticide-susceptible females to mate with either susceptible or resistant male phenotypes; and (4) the effect of multiple matings, on progeny paternity. Sexual maturity in E. connexa was found to begin within 3 days of adult emergence for both sexes, but fully developed after 5 days. The highest frequency of mating exhibited by sexual mature pairs occurred within first hour of pairing and the phenotype for insecticide resistance did not affect the choice of a mating partner. The resistance trait marker in the resistant beetle phenotype indicates that progeny paternity results from a mixture of available sperm and do not depend on mating order. These data suggest that released beetles would have a simple prospect for progeny production for both insecticide resistant and susceptible beetles.

瓢虫甲虫是许多农业害虫的主要捕食者。其中，Eriopis connexa由于害虫管理计划的一些重要特征而脱颖而出，例如常见的发生、选择对拟除虫菊酯杀虫剂具有抗性的种群以及通过使用替代猎物饲养而商业化的可能性。尽管如此，关于一妻多夫的作用及其对该物种的亲子关系的影响知之甚少。瓢虫甲虫进行多次交配，引发了关于一妻多夫和亲子关系的好处的问题。我们通过对 (1) 性成熟年龄，(2) 光相期内的频率和难治性交配行为，(3) 对杀虫剂敏感的偏好进行实验，研究了交配对的选择、精子优先级和后代亲子关系。雌性与易感或抗性雄性表型交配；(4) 多次交配对后代亲子关系的影响。E. connexa被发现在雌雄成虫后 3 天内开始出现，但在 5 天后完全发育。性成熟配对表现出的最高交配频率发生在配对的第一小时内，杀虫剂抗性的表型不影响交配伙伴的选择。抗性甲虫表型中的抗性性状标记表明后代亲子关系是由可用精子的混合物产生的，不依赖于交配顺序。这些数据表明，释放的甲虫对于杀虫剂抗性和易感甲虫的后代生产具有简单的前景。
