“…4). Transitions to vertically transmitted symbionts have been suggested to be driven by evolutionary pressures tied to specialization (35,66), but many heteropteran plant specialists retain environmentally acquired symbioses (6,67), suggesting a more nuanced evolutionary explanation. Comparative approaches focused on sister groups with different transmission strategies in the Heteroptera may yield useful biological correlations, although many additional phylogenetic and biological data will be required.…”

The insect order Hemiptera, one of the best-studied insect lineages with respect to bacterial symbioses, still contains major branches that lack comprehensive characterization of associated bacterial symbionts. The Pyrrhocoroidea (Largidae [220 species] and Pyrrhocoridae [ϳ300 species]) is a clade of the hemipteran infraorder Pentatomomorpha. Studies on bacterial symbionts of this group have focused on members of Pyrrhocoridae, but recent examination of species of two genera of Largidae demonstrated divergent symbiotic complexes in these putative sister families. We surveyed the associated bacterial diversity of this group using paired-end Illumina sequencing and targeted Sanger sequencing of bacterial 16S rRNA amplicons of 30 pyrrhocoroid taxa, including 17 species of Largidae, in order to determine bacterial associates and the similarity of associated microbial communities among species. We also used molecular data (4,800 bp in 5 loci, for 57 ingroup and 12 outgroup taxa) to infer a phylogeny of the host superfamily, in order to trace the evolution of symbiotic complexes among Pentatomomorpha species. We undertook multiple lines of investigation (i.e., experimental rearing, fluorescence in situ hybridization microscopy, and phylogenetic and coevolutionary analyses) to elucidate potential transmission routes for largid symbionts. We found a prevalent and specific association of Largidae with Burkholderia strains of the plant-associated beneficial and environmental clade, housed in midgut tubules. As in other distantly related Heteroptera, symbiotic bacteria seem to be acquired from the environment every generation. We review the current understanding of symbiotic complexes within Pentatomomorpha and discuss means to further investigate the evolution and function of these symbioses. IMPORTANCEObligate symbioses with bacteria are common in insects, particularly Hemiptera, in which various forms of symbiosis occur. However, knowledge regarding symbionts remains incomplete for major hemipteran lineages. Thus, an accurate understanding of how these partnerships evolved and changed over millions of years is not yet achievable. We contribute to our understanding of the evolution of symbiotic complexes in Hemiptera by characterizing bacterial associates of Pyrrhocoroidea, focusing on the family Largidae. Members of Largidae are associated with specific symbiotic Burkholderia strains from a different clade than Burkholderia symbionts in other Burkholderia-associated Hemiptera. Evidence suggests that species of Largidae reacquire specific symbiotic bacteria from the environment every generation, which is a rare strategy for insects, with potentially volatile evolutionary ramifications, but one that must have persisted in Largidae and related lineages since their origin in the Cretaceous Period.

“…Several species are considered to be major agricultural pests (Mitchell, 2000), for example the bean bug, Riptortus pedestris, which is also a model organism for symbiont research (Mitchell, 2000;Takeshita & Kikuchi, 2017). Members of this superfamily also include some of the largest, robust, terrestrial heteropterans and several brightly coloured species (Fernandes, Mitchell, Livermore, & Nikunlassi, 2015;Schuh & Slater, 1995). Within this group, there is also diversity of body forms, varying from slender and elongate to large, foliaceous or winglike expansions on the body and/ or legs (Schuh & Slater, 1995).…”

Phylogenomic analysis suggests Coreidae and Alydidae (Hemiptera: Heteroptera) are not monophyletic

Next‐generation sequencing technologies (NGS) allow systematists to amass a wealth of genomic data from non‐model species for phylogenetic resolution at various temporal scales. However, phylogenetic inference for many lineages dominated by non‐model species has not yet benefited from NGS, which can complement Sanger sequencing studies. One such lineage, whose phylogenetic relationships remain uncertain, is the diverse, agriculturally important and charismatic Coreoidea (Hemiptera: Heteroptera). Given the lack of consensus on higher‐level relationships and the importance of a robust phylogeny for evolutionary hypothesis testing, we use a large data set comprised of hundreds of ultraconserved element (UCE) loci to infer the phylogeny of Coreoidea (excluding Stenocephalidae and Hyocephalidae), with emphasis on the families Coreidae and Alydidae. We generated three data sets by including alignments that contained loci sampled for at least 50%, 60%, or 70% of the total taxa, and inferred phylogeny using maximum likelihood and summary coalescent methods. Twenty‐six external morphological features used in relatively comprehensive phylogenetic analyses of coreoids were also re‐evaluated within our molecular phylogenetic framework. We recovered 439–970 loci per species (16%–36% of loci targeted) and combined this with previously generated UCE data for 12 taxa. All data sets, regardless of analytical approach, yielded topologically similar and strongly supported trees, with the exception of outgroup relationships and the position of Hydarinae. We recovered a monophyletic Coreoidea, with Rhopalidae highly supported as the sister group to Alydidae + Coreidae. Neither Alydidae nor Coreidae were monophyletic; the coreid subfamilies Hydarinae and Pseudophloeinae were recovered as more closely related to Alydidae than to other coreid subfamilies. Coreinae were paraphyletic with respect to Meropachyinae. Most morphological traits were homoplastic with several clades defined by few, if any, synapomorphies. Our results demonstrate the utility of phylogenomic approaches in generating robust hypotheses for taxa with long‐standing phylogenetic problems and highlight that novel insights may come from such approaches.

Como alternativa al descenso en la rentabilidad del cultivo de café, principal fuente económica en el municipio de Inzá (Cauca, Colombia), se establecieron cultivos de pitaya amarilla sin conocer las limitantes fitosanitarias para este cultivo en esta zona. Este trabajo presenta la entomofauna asociada a cultivos de pitaya amarilla en tres predios productivos de Inzá, contrastantes por sus características agronómicas y de paisaje. Se realizó muestreo directo de insectos sobre cada estructura de la planta, muestreo con pases dobles de red entomológica a 50 cm de distancia de la planta y se consideraron factores abióticos e índices de diversidad ecológica. Con muestreo directo se reconocieron 58 familias, prevaleciendo Formicidae (n = 22), Coreidae (n = 11) y Lonchaeidae (n = 7). Con red entomológica se recolectaron cinco órdenes y 56 familias de insectos. Las plantas con mayor densidad de cladodios favorecieron a las familias Lonchaeidae (τ = 1,0; P = 0,00), Formicidae (τ = 1,00; P = 0,007) y Cicadellidae (τ = 1,00; P = 0,00). La precipitación (τ = 1,00; P = 0,00) y la temperatura (τ = 1,00; P = 0,00) se correlacionaron positivamente beneficiando a Lonchaeidae. No se encontraron daños asociados a Dasiops spp. (Diptera). No se confirmó la presencia de D. saltans porque todos los especímenes correspondieron a machos. Los índices de diversidad de Margalef (DMg) = 7,42; Shannon-Wiener (H’) = 3,217 (Alfa) y Whittaker (βw) = 1,0; y Routledge (βr) = 0,25 (Beta) representados principalmente por gran variedad de familias de insectos benéficos. Debe establecerse un sistema de vigilancia entomológica regular y acompañamiento técnico a los productores con miras al sostenimiento económico a largo plazo para este cultivo en el municipio.
