Abstract

Summary: The sap beetles of the genus Nitops (Nitidulidae, Coleoptera) are often found in flowers of columnar cacti like Pilosocereus (Cactaceae). Little is known about the conditions in which these infestations occur and their effects on cacti. The first record of the genus Nitops in northeastern Brazil is presented and different aspects of the ecological interaction between the beetle and columnar cacti of the region are analysed. Quantitative analyses of infestations were performed on 141 samples of flowers, fruits and flower buds collected in the field. A single species of sap beetle, Nitops aff. pilosocerei, was observed in 33% of the flowers (fruits and flower buds did not present infestation). The number of beetles per flower varied from 1 to 126 (average: 12.9 beetles/flower). The male to female ratio was approximately 1:1. Several beetles were found with pollen attached to their exoskeleton. The number of beetles per flower reported is up to 3–4 times greater than other records in the literature. The ecological interaction between beetle and plant is discussed.

巴西东北部树液甲虫与仙人掌科Pilosocereus Byles&Rowley的生态关系

摘要：Nitops属（Nitidulidae，鞘翅目）的树液甲虫经常出现在柱状仙人掌类Pilosocereus（仙人掌科）的花中。人们对这些侵扰发生的条件及其对仙人掌的影响知之甚少。介绍了巴西东北部Nitops属的第一个记录，并分析了该地区甲虫和柱状仙人掌之间生态相互作用的不同方面。对田间采集的141个花朵、果实和花蕾样本进行了虫害定量分析。一种树液甲虫，Nitops aff。在33%的花（果实和花蕾没有受到侵扰）中观察到了毛滴虫。每朵花的甲虫数量从1到126只不等（平均每朵花12.9只）。男女比例约为1:1。有几只甲虫的外骨骼上附着着花粉。据报道，每朵花的甲虫数量是文献中其他记录的3-4倍。讨论了甲虫与植物之间的生态相互作用。
