Abstract:
... The insect cuticle is a composite structure that can further be divided into a few sub-structural layers. Its large moiety comprises a lattice of chitin fibrils and structural proteins, both of which are stabilized by covalent bonding among them. The cuticle covers the whole surface of insect body, and thus has long been suggested for the involvement in defense against entomopathogens, especially ...

In the insect cuticle tanning pathway (sclerotization and pigmentation), the enzyme arylalkylamine N-acetyltransferase (AANAT) catalyzes the acetylation of dopamine to form N-acetyldopamine (NADA), which is one of the major precursors for quinone-mediated tanning. In this study we characterized and investigated the function of TcAANAT1 in cuticle pigmentation of the red flour beetle, Tribolium cas ...

Abstract:
... Within the beetle family Anthicidae or ant-like flower beetles the canthariphilous species Notoxus monoceros shows a pair of notch-like structures on the apices of male elytra. A reservoir- like swelling at the apex of each elytron contains a bilobed gland. Its glandular tubules run into the sclerotized notch. Gaschromatographic investigations of elytral notches and the testes of cantharidin-fed a ...

Abstract:
... A new species, Distenia orientalis sp. n. is described from Southeastern China. It was misidentified as Distenia gracilis (Blessig, 1872) but can be separated from the latter by the color of antennae and legs, structure differences on scape, maxillary palp, pronotum, tibiae, punctures on elytra, etc. Three related species are carefully diagnosed and treated. ...

The elytro-tergal type of the stridulatory apparatus is found in P. jezoensis. The structure involved in acoustic communication of P. jezoensis is present only in males. The plectrum of P. proximus males is re-described. Similarly to that in P. jezoensis, it is formed by two tuber ...

Here we evaluate the expression of sexual dimorphism, the allometric effect on shape variation, and the morphological integration of 2 body structures (elytra and pronotum) in Xyleborus affin ...

Abstract:
... Ceratocystis fimbriata plays a significant role in the initiation of the tree decline disease in mango (Mangifera indica L.), which can kill the plant. The C. fimbriata infection is linked with the presence of the beetle Hypocryphalus mangiferae (Curculionidae: Scolytinae). However, it is unknown how H. mangiferae aids in the transport of the fungus between mango trees. The present study aimed to ...

Abstract:
... We compared the postabdominal architecture of Mastigini with extremely long (Stenomastigus) or short (Palaeostigus) aedeagus. A novel mode of copulation was discovered: males of Stenomastigus insert a paramere between the female's abdomen and elytra, and the intromission is stabilized by several structures of both sexes. The intrinsic aedeagal mechanism is indicated as responsible for inflating th ...

Because the trabecular structure is distributed at the ends of the honeycomb walls, the proposed structure is named an end-trabecular beetle elytron plate crash box, or EBEP crash box for simplification. A comparison between the EBEP crash box and conv ...

Two anterior axillaries (Ax1, Ax2) fuse together; they are hinged to the third axillary plate (Ax3). In turn, Ax3 is hinged with the elytron. During takeoff, a beetle abducts and highly elevates its elytra ( ...
