چکیده
A new species of Dactylopius Costa (Dactylopius gracilipilus Van Dam & May) is described and illustrated. It is morphologically similar to Dactylopius tomentosus (Lamarck), but has more gracile truncate setae, abundant simple pores dorsally, and appears to be host-restricted to Corynopuntia Knuth (Cactaceae: Opuntioidea).

Fungal Community Associated with Dactylopius (Hemiptera: Coccoidea: Dactylopiidae) and Its Role in Uric Acid Metabolism
We studied fungal species associated with the carmine cochineal Dactylopius coccus and other non-domesticated Dactylopius species using culture-dependent and -independent methods. Thirty seven fungi were isolated in various culture media from insect males and females from different developmental stages and Dactylopius species. 26S rRNA genes and ITS sequences, from cultured fungal isolates reve...

The ovaries of the adult cochineal scale insect, Dactylopius coccus Costa (Hemiptera: Coccoidea: Dactylopiidae) are made up of more than 400 short ovarioles of the telotrophic type. The ovarioles develop asynchronously. The ovarioles consist of a germarium with six or seven nurse cells, a vitellarium with an oocyte, and pedicel. A terminal filament is lacking. A maturing oocyte was attached to ...

The genus Dactylopius is the only genus at present in the family Dactylopiidae. Since the name Dactylopius was proposed in 1829, however, numerous other species names belonging to different families of scale insects have been combined with it and these are also listed. The present status and the family placement are also given for each species.

Phylogenetic analyses, from polymerase chain reaction (PCR)-amplified 12S rRNA and 18S rRNA gene 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 sp...
