Field characteristics:
Live adult female elongate oval, slightly convex, cream to tan in colour. Mature adult female produces an elongate white ovisac with 3 shallow longitudinal furrows, which may be straight or curved.
Microscopic diagnosis:
Slide-mounted adult female body elongate oval, remaining membranous at maturity. Stigmatic clefts rather shallow. Anal cleft of moderate depth.
Dorsum
. Derm entirely membranous; dermal areolations usually absent. Setae spiniform, scattered throughout. Pores absent. Preopercular pores oval to circular, present anterior to anal plates. Submarginal duct tubercles present, sometimes numbering 8 or more on each side. Tubular ducts absent. Anal plates together quadrate, each plate with 4 apical setae. Anal ring usually bearing 6 setae.
Margin
. Marginal setae long, acute, fringed or bifid, numerous; with about 20 setae between anterior and posterior stigmatic clefts on each side. Stigmatic clefts distinct but shallow, each containing 3 setae, median seta about 2 times longer than lateral setae.
Venter
. Derm membranous. Pregenital disc-pores mostly each with 7 loculi, present around anogenital fold, and on mediolateral areas of preceding 3 or 4 abdominal segments; a small group also present lateral to each metacoxa and mesocoxa. Spiracular disc-pores each with 5 loculi, present in a narrow band between each spiracle and margin. Microducts present in a broad submarginal band and scattered throughout. Tubular ducts of
3 types
: (i) a duct with short, filamentous inner ductule and minute terminal gland, mainly present in broad submarginal band extending from anal cleft to posterior spiracular disc-pore band, but a few also present on marginal area of head and between spiracular disc pore bands; (ii) a duct rather narrower than
type
(iii), with shallow cup-shaped invagination, long, slender inner ductule, and well-developed terminal gland, present medially on posterior abdominal segments and also in posterior submarginal band intermingled with ducts of
type
(i); and (iii) a duct with a fairly wide inner ductule and well-developed terminal gland, present medially on head, thorax, and first 2 or 3 abdominal segments extending laterally to spiracles. Legs well developed, each with free articulation between tibia and tarsus, and with an articulatory sclerosis; each claw without a denticle; both claw digitules broad and shorter than thin tarsal digitules. Antennae each with 8 segments, with segments
III
and
IV
subequal.
Distribution:
Pulvinaria floccifera
is a cosmopolitan species (
García Morales
et al
. 2016
); in
Iran
, it is found in
Gilan
and
Mazandaran
provinces (
Moghaddam 2013
).
Host-plants:
The species is polyphagous, having been recorded on host-plants belonging to 39 families (
García Morales
et al
. 2016
). In
Iran
, it has been found on
Mespilus germanica
(
Rosaceae
) and
Ilex spinigera
(
Aquifoliaceae
) (
Moghaddam 2013
).
Economic importance:
The species is one of the most important pests of tea (
Camellia sinensis
) gardens in northern
Iran
(
Naeim Amini
et al
. 2010
).
Natural enemies:
The fungal pathogen
Lecanicillium lecanii
(Petch Zare & Gams)
(
Cordycipitaceae
) has been recorded on
P. floccifera
in
Iran
(
Naeim Amini
et al
. 2010
).
