  • morphology of antennal Maxillary Palp and labial Palp sensilla in different larval instars of the asian long horned beetle anoplophora glabripennis motschulsky coleoptera cerambycidae
    Acta Zoologica, 2017
    Co-Authors: Lu Zhang, Yuchao Yang, Lili Ren, Tao Wang, Shixiang Zong
    Abstract:

    The 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, scanning electron microscopy was used to determine the typology, morphology, number and distribution of the sensilla. The antennae had two types of sensilla: the sensilla twig basiconica (s.t.b.) and sensilla basiconica. Three different types of sensilla were observed on the Maxillary Palps, which were the sensilla digitiformia, the sensilla chaetica and the s.t.b. The labial Palps had two types of sensilla: the sensilla chaetica and the s.t.b. The s.t.b. had seven total subtypes, and the sensilla basiconica had two subtypes. The typology, quantity and distribution of sensilla on the antennae, Maxillary Palps and labial Palps remained constant in the five larval instars, but the dimensions of all sensilla types increased throughout the development. We discussed the mechanoreception and the chemoreception of ALB larvae inside the host tree to provide a theoretical understanding and information for further research on the behaviour and the electrophysiology of this devastating forest pest.

    Abstract:

    The 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. In order to clarify the morphology of sensilla on antenna, Maxillary Palp and labial Palp of ALB-W and ALB-Y larvae, we studied the typology, morphology, number and distribution of the sensilla by scanning electron microscopy. The results showed that: (i) the antennae of two biotypes had five types of sensilla, including three types of sensilla basiconica (b.) and two types of sensilla twig basiconica (s.tb); numbers of b.1, b.2, b.3 and s.tb1 on antenna were not significantly different (P > 0.05) between two biotypes, and the numbers of s.tb2 were significantly different (P   0.05) between two biotypes, and the numbers of s.tb1 and s.tb2 were significantly different (P   0.05) between two biotypes. We discuss the relationships between sensilla and damage caused by the larvae inside the host trees.

  • Physiological differences between two sugar-sensitive neurons in the galea and the Maxillary Palp of the spruce budworm larva Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae).
    Journal of insect physiology, 2006
    Co-Authors: V. Hock, P. J. Albert, M. Sandoval
    Abstract:

    The L1 contact-chemoreceptor sensillum on the Maxillary Palp of the spruce budworm larva Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae) was examined electrophysiologically for its responses to stimulation by various pyranose and furanose sugars. The results were compared to those from previous work on the sugar-sensitive neuron of the LST sensillum on the galea. We show that the L1 contact-chemoreceptor sensillum contains one sugar-sensitive neuron with furanose but no pyranose sites. It has response characteristics that differ from those of the sugar-sensitive neuron in the LST. Behavioural 2-choice feeding experiments show that, even with both known sugar-sensitive neurons disabled, larvae can still discriminate between disks treated with either distilled water or α-d-glucose. We conclude that the epipharyngeal sensilla must thus also contain a sugar-sensitive neuron.

  • Electrophysiological responses to sucrose from a gustatory sensillum on the larval Maxillary Palp of the spruce budworm, Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae).
    Journal of insect physiology, 2003
    Co-Authors: P. J. Albert
    Abstract:

    Abstract The tip of the Maxillary Palp in the spruce budworm and other lepidoptera larvae contains a cluster of eight basiconic sensilla. Except for a few electrophysiological recordings from the entire group of these sensilla, no information is available on the response characteristics of any individual one. Using a compound microscope at 320× magnification, with a long working-distance objective, it has been possible to view individual sensilla and to record electrical responses from three of these to some gustatory stimuli in preliminary tests. One of them, sensillum (L1), contains a sugar-sensitive neuron whose responses to a range of sucrose concentrations are reported here. The physiological characteristics of this neuron differ from those of the known sugar-sensitive neuron in the lateral styloconic sensillum on the galea of these same insects. Input of chemosensory information about the same gustatory stimulus by more than one neuron in different mouthpart sensilla is discussed in relation to the feeding habits of the spruce budworm.

  • Gender beyond male and female: Occurrence of a gynandromorph in the Japanese encephalitis vector Culex sitiens (Diptera: Culicidae)
    Acta tropica, 2019
    Co-Authors: Van Lun Low, Meng Li Wong, Jonathan Wee Kent Liew, Sandthya Pramasivan, Nantha Kumar Jeyaprakasam, Indra Vythilingam
    Abstract:

    A gynandromorph of Culex sitiens Wiedemann (Diptera: Culicidae) was attracted to a human during a mosquito surveillance programme conducted in Kuala Lipis, Pahang, Malaysia on July 20, 2019. Gynandromorphism was observed in antennae, Maxillary Palps, legs and wings of the specimen, with distinct male characters on the left and female characters on the right, though the left Maxillary Palp is slightly shorter than the proboscis of a typical male. The abdomen, however, displays well-developed male genitalia. This study represents the first report of oblique gynandromorphism in Cx. sitiens, one of the vectors of Japanese encephalitis in Asia.
