“…The detection of symbionts in reproductive tissues (especially ovaries) indicates their maternal transmission. Indeed, symbionts like Wolbachia and Cardinium are vertically transmitted among rice planthoppers (Bing et al, 2019). The bacterial abundance was similar among different tissues in L. striatellus and S. furcifera, while the fungal abundance was significantly different.…”

“…Cardinium appears to have no effect on the fecundity of females, but hastens nymphal development (Zhang et al, 2012b). Importantly, Cardinium induces CI and is the leading factor of CI in S. furcifera when co-infected with Wolbachia (Nakamura et al, 2012;Zhang et al, 2012a;Bing et al, 2019). Intracellular symbionts influence the rest of the microbiome (Fromont et al, 2019).…”

“…Like most plant sap-feeding Hemipteran insects, rice planthoppers are associated with diverse symbionts, including intracellular bacterial symbionts and yeast-like symbionts (YLS) (Noda, 1974;Chen et al, 1981;Tang et al, 2010;Zhang et al, 2010;Bing et al, 2019). Rice planthoppers are used as powerful insect models for research on host-microbe interactions (Huo et al, 2018).…”

Rice planthoppers are notorious plant sap‐feeding pests which cause serious damage. While several microbes in rice planthoppers have been broadly characterized, the abundance and diversity of bacteria and fungi in field planthoppers are largely unknown. This study investigated the bacterial and fungal community compositions of Chinese wild rice planthoppers Laodelphax striatellus and Sogatella furcifera using parallel 16S rRNA gene amplicon and internal transcribed space region sequencing. The bacteria varied significantly between the species and were partitioned significantly by sex, tissues and host environments in each species. The majority of bacteria were affiliated with the genera Wolbachia, Cardinium, Rickettsia and Pantoea. The abundance of Wolbachia was negatively correlated with that of Cardinium in both planthopper species. Compared with bacteria, the abundance and diversity of fungi did not differ between sexes but both were enriched in the gut. The bacterial community as a whole showed no significant correlation with the fungal community. The majority of fungi were related to Sarocladium, Alternaria, Malassezia, Aspergillus and Curvularia. A phylogenetic analysis revealed that these fungi were closely related to botanic symbionts or pathogens. Our results provide novel insights into the bacteria and fungi of rice planthoppers.

“…Although Wolbachia is a reproductive symbiont in the insects (Stouthamer et al, 1999). However, high relative abundance of Arsenophonus might play a role in killing males (Bing et al, 2019), leading to the high ratio of female/male in the Kaifeng populations. These bacteria may promote insect growth and reproduction by influencing the different metabolic functions that the insects need to survive in the local environment.…”

Almost all insects harbor commensal bacteria in the alimentary canal lumen or within cells and often play a pivotal role in their host's development, evolution, and environmental adaptation. However, little is known about the alimentary canal microbiota and their functions in sap-sucking insect pests of crops, which can damage plants by removing plant sap and by transmitting various plant viruses, especially in the small brown planthopper, Laodelphax striatellus. In this study, we characterized the alimentary canal microbiota of L. striatellus collected from seven regions in China by sequencing 16S rDNA. The insects harbored a rich diversity of microbes, mainly consisted of bacteria from phyla Proteobacteria, Actinobacteria, Firmicutes, Bacteroidetes, and Tenericutes. The composition and abundance of microbiota were more similar as the geographic distance decreased between the populations and clustered by geographic location into three groups: temperate, subtropical, and tropical populations. Although the abundance and species of microbes differed among the populations, the various major microbes for each population performed similar functions based on a clusters of orthologous group analysis. Greater diversity in ecological factors in different regions might lead to higher microbial diversity, thus enabling L. striatellus to adapt or tolerate various extreme environments to avoid the cost of long-distance migration. Moreover, the abundance of various metabolic functions in the Kaifeng populations might contribute to higher fecundity in L. striatellus.

“…Previous studies have shown that endosymbiotic bacteria can manipulate reproduction in other leafhoppers and planthoppers. In the planthoppers Laodelphax striatellus (Fallen, 1826) and Sogatella furcifera (Horvath, 1899) (Hemiptera: Delphacidae), Wolbachia and Cardinium induce cytoplasmic incompatibility between infected and uninfected hosts (Noda 1984, Hoshizaki and Shimada 1995, Noda et al 2001, Nakamura et al 2012, Zhang et al 2012, Bing et al 2019. In leafhoppers of the genus Zyginidia Haupt, 1929 (Hemiptera: Cicadellidae), Wolbachia can skew sex ratio toward females by feminizing genetically determined males (Negri et al 2006) and may be responsible for the production of intersex individuals in Eupteryx Curtis 1829 leafhoppers (Hemiptera: Cicadellidae) (Henke et al 2013).…”

Endosymbiotic bacteria can induce parthenogenesis in many haplo-diploid species, but little is known about their role in asexual reproduction in diplodiploids. Bacteria are essential for reproduction in the asexual lineages of springtails and booklice, and possibly some weevils, but whether they are the causative agent of parthenogenesis remains to be proven. This would require comparing unisexual forms and their closely related bisexual species, but such model species are very rare. Empoasca leafhoppers from the Madeira Archipelago provide an excellent case to test whether bacterial infections can cause parthenogenesis. Here we examined the diversity of the sex-distorting bacteria, Wolbachia, Cardinium, Rickettsia, and Arsenophonus, in three apomictic morphotypes (A, B, C) and three bisexual relatives of Empoasca. Wolbachia of group B was present in all unisexual and bisexual species. Rickettsia were the only bacteria restricted to the three unisexual forms, suggesting an association between infection and asexual reproduction. In addition, we found Asaia for the third time in the Cicadellidae, although this may have little to do with the reproductive mode of its host. Adult females of morphotype C reared on plants watered with tetracycline solution did not result in the production of male offspring. To our knowledge, this is the first study to suggest a possible association between bacterial infection and parthenogenesis in apomictic XO/XX diplodiploid bisexual species based on a range of sex ratio-distorting bacteria.
