The fig weevil Kȏno, 1933 (Coleoptera: ) is an invasive fig tree pest recently introduced in southern Europe. Reported for the first time in France in 1997 as , and then in Italy in 2005 as sp. cf. , is currently threatening fig nurseries, orchards, and wild plants. To date, no control methods have proven to be effective against . Although some attempts have been made to describe the insect's biology and behavior, such information is limited to that obtained from adult samples collected in the field. In particular, because of their xylophagous behavior, scarce information is available on the larval stages of the species. The aim of this study, therefore, was to fill these information gaps on the insect biology and behavior by setting up a laboratory protocol suitable for the rearing of . Using the developed rearing protocol, we assessed the main fitness parameters of the species including oviposition rate, egg hatchability, embryonic, larval and pupal duration and development, immature survival, pupation behavior, pupal weight, emergence, sex ratio and adult morphological parameters. The proposed rearing procedure allowed us to obtain new information on the main features of the insect's biology that may be useful for setting up strategies for its control.
无花果象甲Kȏno,1933年(鞘翅目: )是一种最近被引入南欧的入侵性无花果害虫。1997年在法国首次被报道为 ,随后于2005年在意大利被报道为 sp. cf. ,目前正威胁着无花果苗圃、果园和野生植物。迄今为止,尚无已证明对 有效的防治方法。尽管已有人尝试描述这种昆虫的生物学特性和行为,但此类信息仅限于从野外采集的成虫样本中获得的信息。特别是,由于其蛀木行为,关于该物种幼虫阶段的信息很少。因此,本研究的目的是通过建立适合饲养 的实验室方案来填补这些关于昆虫生物学和行为的信息空白。利用所制定的饲养方案,我们评估了该物种的主要适合度参数,包括产卵率、卵孵化率、胚胎、幼虫和蛹的持续时间及发育、未成熟个体的存活率、化蛹行为、蛹重、羽化、性别比和成虫形态参数。所提出的饲养程序使我们能够获得有关该昆虫生物学主要特征的新信息,这可能有助于制定其防治策略。
