ABSTRACT Phylogenetic analyses, from polymerase chain reaction (PCR)-amplified 12S rRNA and 18S rRNAgene sequences from cochineal insects of the genus Dactylopius present in Mexico, showed that D. ceylonicus, D. confusus, and D. opuntiae are closely related. D. coccus constitutes a separate clade, and D. tomentosus is the most distantly related. Bacterial 16S rRNA sequences from all the Dactylopius species sampled showed a common &bgr;-proteobacteria, related to Azoarcus, also found in eggs… Expand
Fungal Community Associated with Dactylopius (Hemiptera: Coccoidea: Dactylopiidae) and Its Role in Uric Acid Metabolism
TLDR
The presence of fungal genes involved in UA catabolism is confirmed, suggesting that fungi help in the nitrogen recycling process in Dactylopius by uricolysis. Expand
Functional genomics of a Spiroplasma associated with the carmine cochineals Dactylopius coccus and Dactylopius opuntiae
TLDR
Three Spiroplasma genomes independently recovered from metagenomes of adult males and females of D. coccus and D. opuntiae are presented and it is proposed that there is a strong interaction and molecular signaling in the symbiosis between S. ixodetis and the Dactylopius cells. Expand
Evolutionary relationships of flavobacterial and enterobacterial endosymbionts with their scale insect hosts (Hemiptera: Coccoidea)
TLDR
The authors' analyses suggest that Enterobacteriaceae underwent more evolutionary events (losses, duplications and host switches), and their phylogenies showed a lower proportion of congruent nodes between host and bacteria, indicating a more relaxed relationship with scale insects compared with Flavobacteria. Expand
Metatranscriptomic Analysis of the Bacterial Symbiont Dactylopiibacterium carminicum from the Carmine Cochineal Dactylopius coccus (Hemiptera: Coccoidea: Dactylopiidae)
TLDR
In most insects, nitrogen-fixing bacteria are found in the gut, but in this study they are shown to occur in the hemolymph, probably delivering essential amino acids and riboflavin to the host from nitrogen substrates derived from nitrogen fixation. Expand
Candidatus Dactylopiibacterium carminicum, a Nitrogen-Fixing Symbiont of Dactylopius Cochineal Insects (Hemiptera: Coccoidea: Dactylopiidae)
TLDR
Dactylopiibacterium symbionts may compensate for the nitrogen deficiency in the cochineal diet, and may provide essential amino acids, recycle uric acid, and increase the coChineal life span. Expand
Addressing the red flags in cochineal identification: The use of molecular techniques to identify cochineal insects that are used as biological control agents for invasive alien cacti
TLDR
Using the methods developed in this study, biological control practitioners can ensure that the most effective agent species and lineages are used for each cactus target weed, thus maximizing the level of control. Expand
Coexistence of novel gammaproteobacterial and Arsenophonus symbionts in the scale insect Greenisca brachypodii (Hemiptera, Coccomorpha: Eriococcidae)
TLDR
These findings provide evidence for a polyphyletic origin of symbionts of Eriococcidae, and propose the name 'Candidatus Kotejella greeniscae' for its tentative classification. Expand
Genetic variation amongst biotypes of Dactylopius tomentosus
TLDR
This study is the first molecular characterization of cochineal biotypes that, together with Wolbachia sequences, contribute to the better identification of the biotypes of co chineal insects and to the biological control of cacti using host‐specific biotype of the scale. Expand
Genetic variability of Dactylopius opuntiae (Hemiptera, Dactylopiidae) on forage cactus in northeast Brazil.
TLDR
The low genetic variability demonstrates a high degree of relatedness among these D. opuntiae populations, and underpins morphological characterization and supports the monitoring of populations in integrated management programs designed to control this pest. Expand
Range Wide Phylogeography of Dactylopius coccus (Hemiptera: Dactylopiidae)
TLDR
The center of origin of D. coccus is found to be Oaxaca Mexico based on mtDNA data and climate niche modeling and further meta-genomic data are needed to rule out selective sweeps from past and present endosymbionts. Expand

TLDR
The proposed name "Candidatus Uzinura diaspidicola" is proposed for the primary endosymbionts of armored scale insects, which are closely related to bacteria associated with eriococcid and margarodid scale Insects, to cockroach and auchenorrynchan endosYmbiontes and with other similar sequences identified by BLAST searches.

The Opuntia (Cactaceae) and Dactylopius (Hemiptera: Dactylopiidae) in Mexico: a historical perspective of use, interaction and distribution
TLDR
Strategies for in situ conservation combined with re-established use and cochineal production may enhance conservation policies of Dactylopius and Opuntia species. Expand

TLDR
Transmission electron microscopy and in situ hybridization with fluorescently labeled oligonucleotide probes revealed a homogeneous population of symbionts intimately associated with the endothelium of the hepatopancreas, which apparently interact with the microvilli of the brush border by means of a stalk-like cytoplasmic appendage.
