Marelli (Coleoptera: Curculionidae) is the main defoliating beetle of L'Hér. (Myrtaceae) plants worldwide. The suitability of to this pest varies among host plant genotypes. The objective of this study was to evaluate the development, reproduction, and survival of on species and hybrids to assess their suitability to this insect pest in Brazil.
The survival, development, and reproduction parameters were evaluated with feeding leaves of Dehnh., W. Hill., S.T. Blake and on the hybrids of × 'H13' and 'VR3748' in the laboratory.
The duration of the larval stage of was shorter on The pupal stage and the period from larva to adult were equally shorter on and . The viability of instars of this insect was low on both and . The complete lifespan, oviposition period and reproduction parameters of were greater on , lower on and , and intermediate on both hybrids tested.
is the most suitable host for survival, development, and reproduction, while and are the least suitable.
马雷利（鞘翅目：象甲科）是世界范围内造成 L’Hér.（桃金娘科）植物落叶的主要甲虫。 对这种害虫的适宜性因宿主植物基因型而异。本研究的目的是评估 在巴西的 物种和杂种上的发育、繁殖和生存能力，以评估它们对这种昆虫的适宜性。
用 Dehnh.、W. Hill.、S.T. Blake 的叶片以及 'H13' 和 'VR3748' 的杂种来饲养 ，评估其在实验室中的取食、发育和繁殖参数。
在 上的幼虫期持续时间更短。在 和 上，蛹期和从幼虫到成虫的阶段同样更短。这一昆虫各龄期的存活率在 和 上都较低。 在 上，该昆虫的整个寿命、产卵期和繁殖参数较大，在 和 上较低，在两个测试的杂种上则处于中间水平。
是 生存、发育和繁殖最适宜的宿主，而 和 则最不适宜。
