象甲以物种特有的方式操纵寄主植物的特定结构，例如，剪枝、剪叶、卷叶或构造复杂的卷叶，想必是为了确保卵或幼虫的生存。为了描述该科母体植物操纵行为和幼虫取食策略的进化史，通过对核18S和28S核糖体DNA以及线粒体细胞色素氧化酶亚基I基因的测序，进行了分子系统发育分析。我们的分析表明，象甲形成了一个单系群，母体割草行为起源于象甲的一个共同祖先，但后来在几个谱系中消失了。Atelabinae亚科的单系也在高支持度下恢复，但Rhynitinae亚科的单系没有恢复为单系。通过采用基于最大似然法的祖先状态重建，幼虫的叶片取食被推断为从对切梢/叶柄的钻探进化而来。此外，母体卷叶行为可能独立地起源于Attelabinae和Byctiscini谱系，以及几个Deporaini谱系。由于构成卷叶的复杂行为只起源于一次，并且没有从谱系中消失，这些复杂和创新的行为可能有助于谱系的成功和多样化。(C)2012 Elsevier Inc.保留所有权利。
Attelabid weevils manipulate specific structures of their host plants in a species-specific manner, e.g., cutting a shoot, cutting a leaf, rolling a leaf, or constructing sophisticated wrapped leaf rolls, presumably to secure the survivorship of eggs or larvae. To depict the evolutionary history of maternal plant-manipulation behaviours and larval feeding strategies of the family Attelabidae, molecular phylogenetic analyses were conducted by sequencing the nuclear 18S and 28S ribosomal DNA and the mitochondrial cytochrome oxidase subunit I genes. Our analyses indicated that the attelabid weevils form a monophyletic group, and that maternal plant-cutting behaviour originated in a common ancestor of Attelabidae, but was subsequently lost in several lineages. Monophyly of the subfamily Attelabinae was also recovered with high support, but the subfamily Rhynchitinae was not recovered as monophyletic. By employing maximum-likelihood-based ancestral state reconstructions, larval leaf-blade feeding was inferred to have evolved from boring of cut shoots/petioles. Moreover, maternal leaf-rolling behaviours likely originated independently in the Attelabinae and Byctiscini lineages, and in several Deporaini lineages. As the sophisticated behaviours constructing wrapped leaf rolls of Attelabinae originated only once and has not been lost from the lineage, these complex and innovative behaviours may have contributed to the success and diversification of the lineage.
