The greater rice weevil, Sitophilus zeamais, is a serious pest of stored grain. It chews a hole in the grain and deposits an egg inside. For the purpose of excavating a tunnel, these weevils are equipped with effective mandibulate mouthparts for penetrating and boring holes. The mouthparts of the weevil are a long slender snout, which consist of a labrum, a pair of mandibles, a pair of maxillae and a labium. Mothparts exhibit typical morphology of phytophagous coleopteran beetles and have… Expand
Fine Structure and Sensory Apparatus of the Mouthparts of the Maize Weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionoidea: Dryophthoridae)
The evolution of the mouthpart morphology and the putative functional significance of their sensilla are discussed, providing insight into the feeding mechanism. Expand
Functional morphology of the mouthparts of lady beetle Coccinella transversoguttata (Coccinellidae, Coleoptera), with reference to their feeding mechanism
The functional morphology of mouthparts was studied, with special attention to the fine morphology of each part of mouthpart and various kinds of sensilla, to lay a solid foundation for understanding the feeding mechanism of lady beetles. Expand
Functional morphology of the mouthparts of lady beetle Hippodamia variegata (Coleoptera: Coccinellidae), with reference to their feeding mechanism
It is found that the basic components of the mouthpart of H. variegata are the same as those in other lady beetles, which are labrum, mandible, maxillae, labium, and hypopharynx and the morphologies are also quite similar to other species. Expand
Structural comparison of the rostra of two species of weevils coexisting on Ailanthus altissima: the response to ecological demands of egg deposition
Structural differences in the rostra of E. scrobiculatus and E. brandti reflect the functional potential ovipositional tactics of rostra, and provide new insights into the coexistence of two weevil species in the same host A. altissima. Expand
Insights into the Functional Potential of rhe Rice Weevil RostrumBased on Microstructure.
Rstrum could be used as a morphological marker key in differentiating males and females in S. oryzae and this species nearly shares common morphological features of rostrum with S. zeamais and S. granarius, indicating its functional potential in infestation/ovipositional tactics. Expand

Deltamethrin- and spinosad-mediated survival, activity and avoidance of the grain weevils Sitophilus granarius and S. zeamais
Bothspinosad and deltamethrin were able to effectively control the insects, although the latter caused a faster mortality than the former, and spinosad is not as easily recognizable as deltAMethrin by S. zeamais and S. granarius, remaining effective against both species without minimizing as much the potential exposure as delTamsin.

Varietal Resistance Of Wheat To The Rice Weevil (Sitophilous Oryzae) Under Stored Condition
To evaluate the level of resistance of five wheat varieties: Achyut, N.L.971, Bijaya, N.L.297 and Gautam against Sitophilus oryzae (L.), research was carried out at the Entomology laboratory of NepalExpand
Microstructure and mechanical properties of rostrum in Cyrtotrachelus longimanus (Coleoptera: Curculionidae)
The rostrum of Cyrtotrachelus longimanus (JHC Fabre) has high-specific strength and is almost the same as that of the stainless steel, which may provide a biological template to inspire biomimetic lightweight structure design. Expand

The fine structural aspects of the mouthpart using the field emission scanning electron microscopy (FESEM) to reveal its mechano‐dynamic characteristics of this ambrosia beetle are analyzed. Expand
Mouthparts of the bark beetle (Ips acuminatus) as a possible carrier of pathogenic microorganisms
Detailed observation of the cuticular structure of the mouthpart using the field emission scanning electron microscopy (FESEM) is reported for the purpose of demonstrating its possible implication to act as external carriers of pathogenic microorganisms. Expand
Elongated mouthparts of nectar-feeding Meloidae (Coleoptera)
Morphological and anatomical results yield new insights into the functional aspects of proboscides in nectar-feeding Meloidae that probably evolved at least two times convergently, that is, by elongation of the maxillary palps or the galeae. Expand

Sexual dimorphism in head structures of the weevil Rhopalapion longirostre (Olivier 1807) (Coleoptera: Curculionoidea): a response to ecological demands of egg deposition
The present study reveals that the evolutionary emergence of elongated rostra was a key event in the adaptive radiation of weevils, enabling females to bore long channels for egg deposition into various parts of host plants. Expand
