Diversity pattern of insects from Macao based on an updated species checklist after 25 years.

Background: Insects represent one of the most diverse groups in the organism world with extremely rich species and morphological diversity, playing important roles in natural and city ecosystems. Regional compilation of insect species lists helps to clarify the richness of insect species in a region, enhances our understanding the structure and function of a local ecosystem and promotes the protection and development of insect resources. Moreover, it also serves as a valuable reference for cities with small area, large population and high urbanisation like Macao.

Different roles of host and habitat in determining the microbial communities of plant-feeding true bugs.

Background: The true bugs (Heteroptera) occupy nearly all of the known ecological niches of insects. Among them, as a group containing more than 30,000 species, the phytophagous true bugs are making increasing impacts on agricultural and forestry ecosystems. Previous studies proved that symbiotic bacteria play important roles in these insects in fitting various habitats.

300 Million years of coral treaders (Insecta: Heteroptera: Hermatobatidae) back to the ocean in the phylogenetic context of Arthropoda.

Among hundreds of insect families, Hermatobatidae (commonly known as coral treaders) is one of the most unique. They are small, wingless predaceous bugs in the suborder Heteroptera. Adults are almost black in colour, measuring about 5 mm in body length and 3 mm in width.

Symbiotic Microorganisms and Their Different Association Types in Aquatic and Semiaquatic Bugs.

True bugs (Hemiptera, suborder Heteroptera) constitute the largest suborder of nonholometabolous insects and occupy a wide range of habitats various from terrestrial to semiaquatic to aquatic niches. The transition and occupation of these diverse habitats impose various challenges to true bugs, including access to oxygen for the aquatic species and plant defense for the terrestrial phytophagans. Although numerous studies have demonstrated that microorganisms can provide multiple benefits to terrestrial host insects, a systematic study with comprehensive higher taxa sampling that represents aquatic and semiaquatic habitats is still lacking.

Stage correlation of symbiotic bacterial community and function in the development of litchi bugs (Hemiptera: Tessaratomidae).

Bacterial symbionts of insects have been shown to play important roles in host fitness. However, little is known about the bacterial community of Tessaratoma papillosa which is one of the most destructive pests of the well-known fruits Litchi chinensis Sonn and Dimocarpus longan Lour in Oriental Region, especially in South-east Asia and adjacent areas. In this study, we surveyed the bacterial community diversity and dynamics of T.

First record of the cimicomorphan family Plokiophilidae (Hemiptera, Heteroptera) from China, with description of a new species of .

, is described from Xishuangbanna, Yunnan Province, representing the first record of the family Plokiophilidae from China. The new species also represents the first record of the genus in the Oriental Region, a second zoogeographical region besides the Afrotropical Region. Photographs of the live individuals inhabiting a spider web within natural habitats, male and female habitus, wings of adult, male genitalic structures, female abdomen structures and scanning electron micrographs of forewing, head, thorax and legs are provided.

Evaluation of Sample Preservation Approaches for Better Insect Microbiome Research According to Next-Generation and Third-Generation Sequencing.

The microbial communities associated with insects play critical roles in many physiological functions such as digestion, nutrition, and defense. Meanwhile, with the development of sequencing technology, more and more studies begin to focus on broader biodiversity of insects and the corresponding mechanisms of insect microbial symbiosis, which need longer time collecting in the field. However, few studies have evaluated the effect of insect microbiome sample preservation approaches especially in different time durations or have assessed whether these approaches are appropriate for both next-generation sequencing (NGS) and third-generation sequencing (TGS) technologies.

First record of Hermatobatidae from China, with description of Hermatobates lingyangjiaoensis sp. n. (Hemiptera: Heteroptera).

The family Hermatobatidae Poisson, 1965 is recorded for the first time from China and Hermatobates lingyangjiaoensis sp. n. is described.

When did the ancestor of true bugs become stinky? Disentangling the phylogenomics of Hemiptera-Heteroptera.

The phylogeny of true bugs (Hemiptera: Heteroptera), one of the most diverse insect groups in terms of morphology and ecology, has been the focus of attention for decades with respect to several deep nodes between the suborders of Hemiptera and the infraorders of Heteroptera. Here, we assembled a phylogenomic data set of 53 taxa and 3102 orthologous genes to investigate the phylogeny of Hemiptera-Heteroptera, and both concatenation and coalescent methods were used. A binode-control approach for data filtering was introduced to reduce the incongruence between different genes, which can improve the performance of phylogenetic reconstruction.

Phylogeny and the colourful history of jewel bugs (Insecta: Hemiptera: Scutelleridae).

Members of the family Scutelleridae (Heteroptera: Pentatomomorpha: Pentatomoidea) are also called shield bugs because of the greatly enlarged scutellum, or jewel bugs because of the brilliant colours of many species. All scutellerids are phytophagous, feeding on various parts of their host plants. Due to lack of obvious synapomorphies and the failure to apply rigorous phylogenetic methods, the higher classification of Scutelleridae has been disputed for more than 150 years.
