“…Previous works showed that, in different groups of the Pentatomoidea, g-proteobactertial gut symbionts are vertically transmitted through host generations (Schorr, 1957;Abe et al, 1995;Hosokawa et al, 2005;Prado et al, 2006;Kikuchi et al, 2009;Prado and Almeida, 2009b;Kaiwa et al, 2010). In this study, inspection of eggs of lygaeoid and coreoid stinkbugs revealed no stable vertical transmission of the Burkholderia symbionts to their eggs (Table 3).…”

“…In the families Pentatomidae, Plataspidae, Acanthosomatidae, Scutelleridae and Parastrachiidae, their gut symbionts belong to distinct lineages in the g-Proteobacteia, indicating multiple evolutionary origins of the symbiotic associations (Fukatsu and Hosokawa, 2002;Hosokawa et al, 2006Hosokawa et al, , 2010Prado et al, 2006;Kikuchi et al, 2009;Prado and Almeida, 2009a, b;Kaiwa et al, 2010). In several species of the families Pentatomidae, Plataspidae, Acanthosomatidae, Parastrachiidae and Cydnidae, symbiont-free insects suffered retarded growth and/or nymphal mortality, suggesting mutualistic nature of the symbiotic associations (Mü ller, 1956;Huber-Schneider, 1957;Schorr, 1957;Abe et al, 1995;Fukatsu and Hosokawa, 2002;Hosokawa et al, 2006;Kashima et al, 2006;Kikuchi et al, 2009;Prado and Almeida, 2009b).…”

“…All these gut symbionts are vertically transmitted through host generations either via egg smearing in the Pentatomidae, Acanthosomatidae and Scutelleridae (Abe et al, 1995;Prado et al, 2006;Kikuchi et al, 2009;Prado and Almeida, 2009b;Kaiwa et al, 2010), via coprophagy in the Cydnidae (Schorr, 1957), or via capsule transmission in the Plataspidae (Hosokawa et al, 2005).…”

An ancient but promiscuous host–symbiont association between Burkholderia gut symbionts and their heteropteran hosts

Here, we investigated 124 stinkbug species representing 20 families and 5 superfamilies for their Burkholderia gut symbionts, of which 39 species representing 6 families of the superfamilies Lygaeoidea and Coreoidea were Burkholderia-positive. Diagnostic PCR surveys revealed high frequencies of Burkholderia infection in natural populations of the stinkbugs, and substantial absence of vertical transmission of Burkholderia infection to their eggs. In situ hybridization confirmed localization of the Burkholderia in their midgut crypts. In the lygaeoid and coreoid stinkbugs, development of midgut crypts in their alimentary tract was coincident with the Burkholderia infection, suggesting that the specialized morphological configuration is pivotal for establishment and maintenance of the symbiotic association. The Burkholderia symbionts were easily isolated as pure culture on standard microbiological media, indicating the ability of the gut symbionts to survive outside the host insects. Molecular phylogenetic analysis showed that the gut symbionts of the lygaeoid and coreoid stinkbugs belong to a b-proteobacterial clade together with Burkholderia isolates from soil environments and Burkholderia species that induce plant galls. On the phylogeny, the stinkbug-associated, environmental and gall-forming Burkholderia strains did not form coherent groups, indicating host-symbiont promiscuity among these stinkbugs. Symbiont culturing revealed that slightly different Burkholderia genotypes often coexist in the same insects, which is also suggestive of host-symbiont promiscuity. All these results strongly suggest an ancient but promiscuous host-symbiont relationship between the lygaeoid/coreoid stinkbugs and the Burkholderia gut symbionts. Possible mechanisms as to how the environmentally transmitted promiscuous symbiotic association has been stably maintained in the evolutionary course are discussed.

“…1D), their lumen filled with a number of specific bacterial symbionts (22,33,44,64). In some stinkbug species, elimination of the symbiont causes retarded growth and nymphal mortality of the hosts (1,38,48,53,54,65,66,82,93,105), indicating pivotal roles of the symbionts for the host insects. Probably because of their extracellular associations, almost all stinkbugs have evolved postnatal mechanisms for symbiont transmission (see below), unlike the intracellular symbiosis established through prenatal transmission (e.g.…”

Endosymbiotic Bacteria in Insects: Their Diversity and Culturability

Many animals and plants possess symbiotic microorganisms inside their body, wherein intimate interactions occur between the partners. The Insecta, often rated as the most diverse animal group, show various types of endosymbiotic associations, ranging from obligate mutualism to facultative parasitism. Although technological advancements in culture-independent molecular techniques, such as quantitative PCR, molecular phylogeny and in situ hybridization, as well as genomic and metagenomic analyses, have allowed us to directly observe endosymbiotic associations in vivo, the molecular mechanisms underlying insect-microbe interactions are not well understood, because most of these insect endosymbionts are neither culturable nor genetically manipulatable. However, recent studies have succeeded in the isolation of several facultative symbionts by using insect cell lines or axenic media, revolutionizing studies of insect endosymbiosis. This article reviews the amazing diversity of bacterial endosymbiosis in insects, focusing on several model systems with culturable endosymbionts, which provide a new perspective towards understanding how intimate symbiotic associations may have evolved and how they are maintained within insects.

“…Seed-feeding Brachypelta (Cydnidae) and Oncopehus (Lygaeidae) may extract water from succulent parts of the host-plant, and from a wide variety of non-hosts. Water-uptake from these plants is not induced by specific attractants as is food-uptake (SCHORR, 1957;EGGERMANN & BONGERS, 1971). The ability of seed-sucking bugs to perceive various secondary plant substances dissolved in water, might have provided a regulatory cue to them when they were sucking on non-host plants for water (SCHOONHOVEN & DERKSEN-KOP-PERS, 1973).…”
