2 Terms and definitions

The following terms and definitions are applicable to this document.

2.1

Scale

The protective structure of scale insect of diaspididae, which is independent from polypide;

is worn on the back or ventral side or dorsal ventral side of polypide; and is bonded by

gland secreta, anus colloid excrement on the pygidium AND ecdysis of nymph.

2.2

Prosoma

The front part of polypide of scale insect of diaspididae. It is usually formed by

coalescence of head, protothorax and mesothorax, without any merogenesis.

2.3

Postsoma

The rear part of polypide of scale insect of diaspididae. It usually consists of metathorax

and several uromeres of abdomen, with un-obvious merogenesis.

2.4

Pygidium

The tabular body formed by coalescence and sclerotization of several joints at end of

abdomen. It is related to formation of scale of diaspididae.

2.5

Pygidial lobes

The characteristics are as follows.

— Polypide is covered with wax scale. There are spots formed by ecdysis of first and

second instar nymph on scale, in long shape or round shape;

— Polypide somites are reduced. Several rear somites at abdomen turn into hardened

pygidium. Accessory structures such as pygidial lobes, pygidial plates and

paraphyses in different shape, distribution and quantity exist at edges of pygidium;

— Tentacle degenerates into tubercle-type substance, without merogenesis, with one

to several long hairs at its ends, in front of mouthpart. Mouthpart is in middle of

segmental venter of prosoma. Beak substrate is strong, in form of one joint, usually

in round;
