Electrophysiological recordings from the labial and maxillary palps of the Asian longhorned beetle, Anoplophora glabripennis, revealed their ability to detect several volatile chemicals, including water vapor and acetic acid. The results indicate that these appendages may play a large role in this beetle's assessment of its immediate environment.

AbstractThe various sensilla on the antennae and on the labial and maxillary palps of Blattella germanica (L.) were studied. Thick‐walled chemoreceptors with fluted shafts and articulated bases are located on the antennae and on the labial and maxillary palps. Thin‐walled chemoreceptors, without fluted shafts or articulated bases, are restricted to the

AbstractCallosobruchus chinensis(Coleoptera: Bruchidae) is the main pest of mungbean (Vigna radiata) especially during seed storage. To provide background information for chemical ecology studies, we examined the externalmorphology of the antennal, maxillary palp and labial palp sensilla of this insect with scanning electron microscopy. The antennae of

Abstract Cryptorrhynchus lapathi (Linnaeus) (Coleoptera: Curculionidae) is an important cosmopolitan wood-boring insect pest. Its larval stages damage salicaceous plants and thereby cause serious economic losses to the forest industry. In this study, we used scanning electron microscopy to record the number, typology, morphology, and distribution of ...

AbstractThe Asian long‐horned beetle (ALB) is one of the most important international trunk‐boring insect pests of forest trees, which has caused enormous losses in the forests of China, the USA and some countries in Europe. To investigate the morphology of the antennal, maxillary palp and labial palp sensilla in the five larval instars of the ALB ...

AbstractEucryptorrhynchus scrobiculatus (Olivier) and E. brandti (Harold) are two wood boring pests of Ailanthus altissima (Mill.) Swingle (tree of heaven) and the variety Ailanthus altissima var. Qiantouchun. These beetles attack healthy trees and bore into roots and trunks during the larval stage.

In insects, pheromones are detected by olfactory sensory neurons (OSNs) of the antennae that co-express pheromone receptors (PRs) and the "sensory neuron membrane protein 1" (SNMP1). Beyond its relevance for pheromone detection via the antenna, little is known about a potential expression and functional role of SNMP1 in cells of other chemosensory ...

THE ROLE OF THE MAXILLARY AND LABIAL PALPS IN THE FEEDING BEHAVIOUR OF SCHISTOCERCA GREGARIA
Entomologia Experimentalis et Applicata, 1979The role of the maxillary and labial palps in the initiation and maintenance of feeding has been analysed in female fifth‐instar nymphs of Schistocerca gregaria. The ability to perceive single chemicals prior to feeding and to feed to repletion on them is markedly reduced in the absence of the palps.

AbstractThe Asian long‐horned beetle (ALB) is one of the most important wood‐boring insects worldwide that damages broad‐leaved trees, primarily poplar, willow, elm and maple. Based on the color of the spots on the elytra, the beetles are separated into white‐spotted (ALB‐W) and yellow‐spotted (ALB‐Y) Asian long‐horned beetles.

The labial and maxillary palps of the bark beetle, Ips typographus, possess a diversified array of sensilla. There are four types of sensilla possessing a single tubular body indicating a mechanoreceptive function. The variation of the associated cuticular structures of these sensillar types ranges from long bristles to cavities within the cuticle ...
