Scale insects of the families Coccidae
and Pseudococcidae (Hemiptera) and thrips Frankliniella schulzei (Trybon) (Thysanoptera: Thripidae) were observed in D.
Other common families were Psocidae (common barklice), Sciaridae (dark winged fungus gnats), Formicidae (ants) and Coccidae
(scales) (Table 2).
There are 22 families--with more than 7,300 species--the largest and most common being Diaspididae, or armored scales; Coccidae
, or soft scales; and Pseudococcidae, commonly known as mealybugs.
The first survey, conducted in 2009, revealed the presence of 11 species of scale insects (Hemiptera: Coccoidea): Stictococcidae (2 species), Coccidae
(1 species) and Pseudococcidae (8 species) (N'Guessan 2013).
Soft scales of the family Coccidae
(Hemiptera: Coccoidea) are phytophagous insects that infest leaves, branches and fruits of various plants.

The family Aphelinidae in these mountain localities therefore has 3 groups of hosts: Aleyrodidae (12 parasitoid species, 65% of all the Aphelinidae species), Coccidae
(1 species, 5%) and Diaspididae (5 species, 25%).

tepicana nests, that adults present subapterism, and that ant hosts are not associated with Aphididae or Coccidae
(Wheeler 1907), such an association is unlikely to be only circumstancial; however, a primary parasitic relationship was never proved and the wasp developmental stages remained unknown.
