Culex quinquefasciatus, the southern house mosquito, is highly dependent on its olfactory system for vector-related activities such as host seeking and oviposition. The antennae are the primary olfactory organs in mosquitoes. We describe 5 morphological types of sensilla on the antenna of C. quinquefasciatus: 1) a pair of sensilla coeloconica located at the distal tip, 2) long and short sensill...

Parasitoid wasps of the genus Sclerodermus (Hymenoptera: Bethylidae) are an important natural enemy of the Japanese pine sawyer beetle Monochamus alternatus Hope (Coleoptera: Cerambycidae). In this study, we used scanning electron microscopy to examine the external morphology of the antennal sensilla of Sclerodermus sp. Antennae of females and males comprised the scape, pedicel, and 11 flagello...

The oriental armyworm, Mythimna separata (Walk), is one of the most serious pests of cereals in Asia and Australasia. The structure and distribution of the antennal sensilla of M. separata were studied by scanning electron microscopy and transmission electron microscopy. The results showed that antennae of both female and male M. separata are filiform in shape. Three groups and seven morphologi...

Antennal sensilla of some forensically important fly species in the families Calliphoridae (Chrysomya megacephala, Chrysomya rufifacies, Chrysomya nigripes and Lucilia cuprina), Sarcophagidae (Parasarcophaga dux) and Muscidae (Musca domestica) were studied using scanning electron microscopy. Five types of sensilla were observed: trichoid, basiconic, coeloconic, styloconic and sensory pit. Only ...

The antennal sensilla of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), were examined using scanning and transmission electron microscopy. Male and female antennae have a scape, pedicel, and nine ßagellomeres. Both male and female antennae share Þve sensillum types: sensilla chaetica (mechanoreceptors), three types of sensilla basiconica (olfactory), and uniporo...

BACKGROUND & OBJECTIVES The sensilla and sensory mechanism play a significant role in hostseeking and oviposition behaviour of mosquitoes, which enable them to transmit various diseases to humans. Aedes albopictus (Skuse) has emerged as a major vector of Chikungunya virus in the recent epidemics in most parts of southern India. Studies on the sensory structures of dengue vector, Aedes aegypti (...

Adult Lepidoptera use their antennae to probe their distant and proximate environment with sensory organs which detect volatile and contact chemicals. In this work, we have investigated the role and the sensitivity of antennal contact chemoreceptors of Spodoptera littoralis. Adults of both sexes have long and filiform antennae composed of about 70 flagellomeres. Each flagellomere bears six tast...

Antennal sensilla are important functional elements of sensory systems in insects. This study aimed to determine the morphology and structure two species genus Hoplopyga. Adults Hoplopyga liturata (Olivier, 1789) were collected traps with sugarcane juice as an attractant. Thereafter, larvae albiventris (Gory Percheron, 1833) mounds termites (Cornitermes cumulans (Kollar, 1832) Isoptera). Then, ...

Extreme miniaturization implies a high degree of optimization, rendering the retention non-functional organs almost impossible. Two unique non-porous placoid sensilla on antennae females Megaphragma were described in literature. Placoid Hymenoptera have an olfactory function and always bear pores; apparent absence pores therefore raises questions whether such are functional their surface sculpt...

Proboscis structure and sensilla types are important morphological characters for the systematic analysis of Lepidoptera families. There is no study on proboscis Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae) despite fact that it an pest. For this purpose, A. were investigated by using stereomicroscope scanning electron microscope in detail. The results show has three sensillum (sensi...
