Red Wax Scale, Ceroplastes rubens Maskell (Insecta: Homoptera: Coccidae)

A facultative association between Plebeia droryana (Friese, 1900) (Hymenoptera: Apidae: Meliponini) and a wax scale insect, Ceroplastes janeirensis (Hemiptera: Coccoidea: Coccidae).

Ants and bees (Hymenoptera) are frequently associated with scale insects (Hemiptera: Coccoidea) and other Sternorrhyncha in a mutualistic relationship. Associations with ants are best known, and they tend to clean, protect and even transport these insects in exchange for honeydew (Way, 1963). Studies between coccoids and bees are less common, although in some regions of Europe the associations ...

A new genus and species of Chamaemyiidae (Diptera: Lauxanioidea) from South America feeding on Ceroplastes wax scales (Hemiptera: Coccidae), and status of the genus Ortalidina as a chamaemyiid

A new genus and species of Chamaemyiidae (Diptera: Lauxanioidea) is described and illustrated, namely Chamaeleucopis, gen. nov. (type species Chamaeleucopis trevas, sp. nov.), a predator of Ceroplastes wax scales on guava from Brazil. In addition, the previously unrecognized genus Ortalidina Blanchard 1852 (type species Ortalidina cellularis Blanchard 1852), mainly from the Neotropics, is recog...

Spiroplasma symbiont of the pea aphid, Acyrthosiphon pisum (Insecta: Homoptera).

From a laboratory strain of the pea aphid, Acyrthosiphon pisum, we discovered a previously unknown facultative endosymbiotic bacterium. Molecular phylogenetic analysis based on 16S ribosomal DNA revealed that the bacterium is a member of the genus Spiroplasma. The Spiroplasma organism showed stable vertical transmission through successive generations of the host. Injection of hemolymph from inf...

Cloning and Expression Analysis of Four Heat Shock Protein Genes in Ericerus pela (Homoptera: Coccidae)

To explore the function of small heat shock protein genes (shsps) and hsp70 in Ericerus pela, we cloned the full-length cDNA sequences of hsp21.5, hsp21.7, hsp70, and hsc70 and the genomic sequence of hsc70. Open reading frames of the four hsps were 570, 564, 1,908, and 1,962 base pairs (bp), respectively, which encode proteins with calculated molecular mass of 21.5, 21.7, 69.8, and 71.6 kDa. A...
