(1963) and Krombein et al. (1979) for the
tessellated scale.
REMARKS: Young females of this scale insect
can be confused with brown soft scale. However,
the tessellations appear early in the last instar,
and this is distinctive (Ferris in Zimmerman
1948). According to Gill et al. (1977), the curved
dorsal setae of E. tessellatus are distinctive from
those of C. hesperidum, which are spinelike.

tubercles (Fig. 41, E) number 10-12. A small
cluster of disc pores (Fig. 41, G) anterior to anal
plates. The combined anal plates nearly form a
square. VENTER-Derm membranous. Antennae
(Fig. 41, K) normally 7 or 8-segmented. Legs
well developed with tibiotarsal scleroses.
Multilocular pores (Fig. 41, N) in vulvar area,
each with 5-8 loculi. Spiracular furrows narrow,
usually one pore wide, occasionally 2 pores wide.
MARGIN-Marginal setae (Fig. 41, B) small,
slender, sometimes bifid apically, longer at
posterior end of abdomen. Spiracular setae (Fig.
41, D) 3 at each spiracular cleft with median seta
ca. 2X length of laterals.

whose original home was probably the
Neotropical' region (Borchsenius 1957).

Madeira, Mauritius, North Africa, Samoa,
Seychelles, Solomon Islands, Sri Lanka, Taiwan,

BIOLOGY: Qne or 2 generations occur per year
and in greenhouses generations will overlap.
Found on leaves and stems. On leaves, in-
dividuals 'will frequently be asymmetrical
because of their position near leaf veins. This
species isovoviviparous.
ECONOMIC IMPORTANCE: A minor pest in
south Florida when commercial nurseries neglect
control programs (Dekle 1973). *

Compere is the only parasite listed by both Peck
