<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Insect morphology, as an important branch of entomology, focuses on the study of insect structure and function, including comparative morphology, functional morphology, and developmental morphology. This paper reviews the development of insect morphological research, highlighting the current research hotspots and technological advances, such as scanning electron microscopy, micro-computer tomography (micro-CT), and geometric morphometric analysis. The paper also discusses how those technology has driven the development of fields such as insect taxonomy, evolutionary biology, and ecology, and foresees the possible future research directions, including interdisciplinary integration and the application of artificial intelligence technology. The paper aims to elucidate the important role of insect morphology in the field of entomology and provide suggestions for future research.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study, the morphology and ultrastructure of the compound eye of L. lewisii were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), micro-computed tomography (μCT), and 3D reconstruction. The compound eye of L. lewisii was of the apposition type, with an average of 121.88 ± 7.64 ommatidia in males and 119.00 ± 4.71 ommatidia in females. Each ommatidium was composed of a biconvex cornea, an acone consisting of four cone cells, eight retinular cells along with the rhabdom, two primary pigment cells, and numerous secondary pigment cells. The open type of rhabdom in L. lewisii consists of six peripheral rhabdomeres contributed by the six peripheral retinular cells (R1~R6) and two vertically attached central rhabdomeres contributed by R7 and R8 respectively. The orientation of microvilli suggested a weak sensitivity to polarized light perception.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The original or primitive venation of mayflies was not presented clearly upon living materials before, this mostly results from the deform of mayfly imaginal wingbase. Some nymphs of large mayflies of China, like Siphluriscus chinensis, Ephemera pictipennis and Siphlonurus davidi, however, show some clues. Together, they demonstrate that in mayflies, subcostal brace maybe originated from longitudinal vein Anterior Subcostal (ScA), stems of Radius (R) and Media (M) are always fused at base, Media Posterior (MP) leave them first, then the branch of Rs (Radial Section)+MA (Media Anterior), Cubitus (Cu) disconnected to any other veins. Additionally, all longitudinal veins of mayflies fused with their sclerotized base respectively but without any moveable sclerite. Instead, base of R+M of mayflies sclerotized into a single one big plate, and all sclerites of wingbase are fused together rigidly by sclerotized wingbase, which disables any possible folding of mayfly wings. Phylogenetically, in the order Ephemeroptera, the different positions of ScA and Cu leaded to different and diverse venations and lineages of Ephemeroptera. In the Pterygota, the Ephemeroptera has the same fused pattern of R+M and three axillary sclerites as the Neoptera while the Odonata has the fused Cu+M, which disproves the monophyly of Paleoptera.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The infection process of Beauveria bassiana strain B1 on the body wall of adult Sitona callosus were observed using SEM and TEM to elucidate the pathogenic mechanism. Following inoculation, B. bassiana conidia adhered to the rough areas and concave regions of S. callosus. Germination occurred between two ommatidium depressions 12 hours post-inoculation, initiating invasion into the body wall through mechanical pressure and enzymatic action. Infiltration of B. bassiana was observed in the digitus 48 hours after inoculation, establishing a parasitic relationship with the host organism. At 72 hours post-inoculation, the epidermal layer undergoes deformation, while the endothelium layer initiates separation. The adipose tissue and muscular fibers undergo destruction. Mycelium spread throughout elytron and penetrated setal alveolus. By 96 hours post-inoculation, mycelial growth continued to invade other tissues until complete colonization occurred along with spore formation resulting in host mortality. At 120 hours, mycelium emerged from the host's body enveloping its corpse while the apoptosis of mycelium was observed at 144 h in vitro. The attachment of B. bassiana was influenced by the physical structure of S. callosus. The conidia parasitize S. callosus 96 hours post-inoculation, leading to the onset of disease and subsequent mortality in the host, demonstrating a high degree of pathogenicity.]]></description>

<link><![CDATA[http://hjkcxb.alljournals.net/hjkcxben/ch/reader/view_abstract.aspx?file_no=202406010&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Tessaratoma papillosa is a pest on litchi (Litchi chinensis) and longan (Euphoria longan). Both adults and nymphs feed on the tender buds, flowers and fruits of the host plant. This study used scanning electron microscope to observe the selected structures of sensilla on the surface of female and male adults of the T. papillosa, including antennae, labium, tarsi (forelegs, midlegs, hindlegs) and abdomen. A total of 7 types of sensilla were observed, including sensilla trichodea, sensilla chaetica, sensilla basiconica, sensilla coeloconic, sensilla ampullacea, sensilla campaniformia and trichobothria. Among them, 5 subtypes of sensilla trichodea were observed; 2 subtypes were observed for both sensilla chaetica and sensilla basiconica. The types, morphology and distribution of sensilla are consistent between female and male adults. Among the observed structures, the types of sensilla on the antennae are the most abundant, with all types of sensilla except for trichobothria; 5 types of sensilla were observed on the labium except for sensilla coeloconic and trichobothria; sensilla chaetica and sensilla ampullacea were observed on the tarsi of each leg; trichobothria was observed on the abdomen; sensilla trichodea and sensilla ampullacea were observed at the ostiole and evaporatorium of metathoracic scent gland. This research provides a morphological basis for exploring the relationship between the sensilla on the surface and behavioral responses of T. papillosa, as well as the mechanisms of signal perception and response, thus providing a scientific basis for further research on behavioral regulation based prevention and control strategies.]]></description>
