Abstract

The Asian corn borer, Ostrinia furnacalis (Guenée), is one of the most destructive lepidopteran pests affecting maize in Asia. Previous research on the feeding behavior of O. furnacalis has mostly focused on larvae, but the adult feeding preference has been unclear hitherto. In this study, we investigated the ultramorphology of the proboscis and sensilla of O. furnacalis using scanning electron microscopy and made morphological comparisons between the sexes, attempting to make predictions on the food preference and feeding behavior of the adults. The proboscis of O. furnacalis is divided into zones 1 and 2 with three types of sensilla, namely chaetica, basiconica, and styloconica. The entire proboscis and zone 2 of the females are significantly longer than those of the males. The main sexual difference in the sensilla is shown in the number of sensilla styloconica, which are eight in females but nine in males. The feeding preference of adult O. furnacalis is discussed based on the morphology of the proboscis and sensilla.

亚洲玉米螟 Ostrinia furnacalis（鳞翅目：玉米螟科）长鼻和感觉器的超形态学研究

亚洲玉米螟（Ostrinia furnacalis (Guenée)）是影响亚洲玉米的最具破坏性的鳞翅目害虫之一。以往对 O. furnacalis 取食行为的研究主要集中于幼虫，但迄今为止成虫的取食偏好尚不清楚。在这项研究中，我们利用扫描电子显微镜研究了O. furnacalis的探针和感觉器的超形态，并对其雌雄进行了形态学比较，试图对成虫的食物偏好和取食行为做出预测。O.furnacalis的长鼻分为1区和2区，有三种类型的感觉器，即chaetica、basiconica和styloconica。雌性的整个长鼻和第 2 区明显长于雄性。感觉器的主要性别差异表现在雌性感觉器的数量上，雌性为 8 个，而雄性为 9 个。根据长鼻和感觉器的形态，讨论了成虫 O. furnacalis 的取食偏好。

期刊介绍： Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
