Diagnosis.
Ulobaris loricata
(
Fig. 16
) can be recognized by flat, fringed fore legs and a small third tarsite.
Distribution.
The species has been known from Central Asia, SE Europe and
Mongolia
(
Prena 2011
) and is reported here for the first time from
China
(Gansu, Inner
Mongolia
, Ningxia, Xinjiang) (
Fig. 19
).
Biology.
Larva and adult are oligophagous on a range of
Amaranthaceae
, including
Amaranthus albus
,
A. blithoides
,
A. retroflexus
,
Atriplex sibirica
,
Bassia hyssopifolia
,
B. scoparia
,
Beta vulgaris
,
Ceratocarpus arenarius
and
Kali turgidus
(
Kabakhchi 1938
;
Aleeva 1953
;
Brunner 1957
;
Korotyaev
et al
. 2005
; unpubl. label data).
Aleeva (1953)
considered
U. loricata
as one of the three main pests of sugar beet in
Kazakhstan
, particularly on dry, sandy soil. The latter habitat is needed because the weevil digs more than
20 cm
deep into the ground, vertically along the root, to avoid high daytime temperatures. It feeds mostly on the root during the day and mostly on the stalk at night. Eggs are laid in the root between late May and early September. Even though some beet roots may have over
100 larvae
, infestations are not obvious at least in the beginning. Larvae and already eclosed adults overwinter in the root and the new generation starts to emerge in late April. Pteromalid wasps of the genera
Anisopteromalus
Ruschka
and
Stenoselma
Delucchi
parasitize the larva (M. N. Nikolskaja in
Aleeva 1953
;
Dzhanokmen & Ertevtsyan 1990
).
