Diagnosis
.
–
A large species; face fulvous with a pair of medium sized circular black spots; postpronotal lobes and notopleura yellow; scutum shining black; lateral and medial postsutural vittae present; mesopleural stripe reaching midway between anterior margin of notopleuron and anterior
npl.
seta; scutellum yellow with a black apical spot; wing with a narrow fuscous costal band confluent with R
2+3
and remaining narrow beyond apex of this vein before expanding across apex of R
4+5
, a broad fuscous cubital streak, pale fuscous along dm-cu crossvein; cells bc and c colourless; microtrichia in outer corner of cell c only; abdominal terga III-V each with a dark fuscous to black ‘T’ pattern.
Attractant. –
Cue lure.
Distribution.
–
Distributed across subtropical southeast Asia. New record for
Bhutan
.
Hosts.
–
Flowers of species in the Family
Cucurbitaceae
(see
Allwood et al., 1999
).
Remarks
.
–
Bactrocera (Zeugodacus) scutellata
(Hendel)
is a large species readily distinguished by the shining black scutum, lateral and medial postsutural vittae broader than in
B. scutellaris
(Bezzi)
, face with circular black spots, scutellum yellow with a black apical spot, femora entirely fulvous, 4
sc
. setae, wing with a strong supernumerary lobe and broad cubital streak, costal band confluent with R
2+3
and remaining narrow beyond apex of R
2+3
before widening gradually across apex of R
4+5
, abdominal terga III-V each with a separate general ‘T’ pattern. As for
B. diversa
(Coquillett)
and
B. scutellaris
,
B. scutellata
attacks flowers of some
Cucurbitaceae
species so may have pest status but no quarantine significance for export trade.
