ABSTRACTObligate symbiotic associations are present in a wide variety of animals with a nutrient-restricted diet. Aphids (hemiptera: Aphididae) almost-universally hostBuchnera aphidicolabacteria in a specialised organs (called bacteriomes). These bacteria supply the aphid with essential nutrients lacking from their diet (i.e. essential amino acids and some B vitamins). Some aphid lineages, such as species from the Lacninae subfamily, have evolved co-obligate associations with secondary endosymbionts, deriving from a loss of biotin-and riboflavin-biosynthetic genes. In this study I re-analyse previously published sequencing data from the banana aphidPentalonia nigronervosa. I show that the metabolic inference results from De Clercket al.(2015) are incorrect and possibly arise from the use of inadequate methods. Additionally, I discuss how the biased interpretation of their antibiotic treatment analyses together with the incorrect metabolic inference resulted in the erroneous suggestion “that a co-obligatory symbiosis betweenB. aphidicolaandWolbachiaoccurs in the banana aphid”.

Aphids associated with papaya plants were collected from two sites in Puerto Rico (Isabela and Corozal) and three farms in Homestead, Florida. Between the two regions, Florida and Puerto Rico, twenty-one species of aphids from 12 genera were identified: Aphis sp., Aphis illinoisensis Shimer, Aphis spiraecola Patch, Aphis gossypii Glover, Aphis craccivora Koch, Aphis iddletonii (Thomas), Aphis nerii Boyer de Fonscolombe, Hyperomyzus carduellinus (Theobald), Hysteroneura setariae (Thomas), Lipaphis pseudobrassicae (Davis), Picturaphis sp., Pentalonia nigronervosa Coquerel, Schizaphis graminum (Rondani), Sarucallis kahawaluokalani (Kirkaldy), Shinjia orientalis (Mordvilko), Schizaphis rotundiventris (Signoret), Toxoptera citricida (Kilkardy), Toxoptera aurantii (Boyer de Fonscolombe), Tetraneura nigriabdominalis (Sasaki), Uroleucon ambrosiae (Thomas), and Uroleucon pseudoambrosiae (Olive). The number of species was greater in Florida (n = 14) than in Puerto Rico (n = 11). Differences among species were also found between sites in Puerto Rico, with 10 species in Corozal and six in Isabela. Only one species, A. illinoisensis, was common at all sites sampled, whereas three additional species, A. spiraecola, A. gossypii, and A. craccivora were collected in both the Corozal, Puerto Rico, and the Florida areas. The difference in species composition between Puerto Rican sites (Corozal and Isabela) and between localities (Florida and Puerto Rico) is probably associated with differences in agricultural crops or weeds present in each region.

AbstractThe banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae), is a major pest of cultivated bananas (Musa spp., order Zingiberales), primarily due to its role as a vector of Banana bunchy top virus (BBTV), the most severe viral disease of banana worldwide. Here, we generated a highly complete genome assembly of P. nigronervosa using a single PCR-free Illumina sequencing library. Using the same sequence data, we also generated complete genome assemblies of the P. nigronervosa symbiotic bacteria Buchnera aphidicola and Wolbachia. To improve our initial assembly of P. nigronervos a we developed a k-mer based deduplication pipeline to remove genomic scaffolds derived from the assembly of haplotigs (allelic variants assembled as separate scaffolds). To demonstrate the usefulness of this pipeline, we applied it to the recently generated assembly of the aphid Myzus cerasi, reducing the duplication of conserved BUSCO genes by 25%. Phylogenomic analysis of P. nigronervos a, our improved M. cerasi assembly, and seven previously published aphid genomes, spanning three aphid tribes and two subfamilies, reveals that P. nigronervos a falls within the tribe Macrosiphini, but is an outgroup to other Macrosiphini sequenced so far. As such, the genomic resources reported here will be useful for understanding both the evolution of Macrosphini and for the study of P. nigronervosa. Furthermore, our approach using low cost, high-quality, Illumina short-reads to generate complete genome assemblies of understudied aphid species will help to fill in genomic black spots in the diverse aphid tree of life.

É relatada a ocorrência de Aphis spiraecola Patch, 1914 (Hemiptera: Aphididae: Aphidini) e Pentalonia nigronervosa Coquerel, 1859 (Hemiptera: Aphididae: Macrosiphini) atacando Xanthosoma sagittifolium (L.) Schott (Alismatales: Araceae) no Brasil. Devido ao ataque dos pulgões, as folhas da planta ornamental apresentaram áreas esbranquiçadas, principalmente ao redor da nervura central, e amplas áreas cobertas com secreção açucarada liberada pelos insetos. Junto com os pulgões foram identificados um predador, Cycloneda sanguinea (L., 1763) (Coleoptera: Coccinellidae), um parasitoide, Aphidius colemani Viereck, 1912 (Hymenoptera: Braconidae), e um hiperparasitoide, Syrphophagus aphidivorus (Mayr, 1876) (Hymenoptera: Encyrtidae). Este é o primeiro registro de associação hospedeira entre X. sagittifolium e A. spiraecola no mundo.

A combined computational and experimental analysis of metabolism in the symbiosis between the pea aphid and its obligate endosymbiont Buchnera aphidicola redefines existing notions of symbiotic nitrogen recycling. As a consequence of metabolic pathways shared between the partners, the insect recycles waste ammonia into essential amino acids (EAAs) that are lacking in its diet of sugar-rich but nitrogen-poor plant phloem sap.
