Zusammenfassung: | Sarta longhorned beetle (SLB),
Aeolesthes sarta
Solsky, is an economically important pest of fruit and shade trees in central and east Asia. Choice, no-choice, and larval insertion experiments were conducted to determine SLB oviposition preference and larval host suitability on six hardwood tree species including
Ulmus carpinifolia
Borkh.,
Ulmus carpinifolia
var.
umbraculifera
Rehd.,
Platanus orientalis
L.,
Populus alba
L.,
Salix alba
L., and
Fraxinus rotundifolia
Miller subsp.
persica
(Boiss.), under laboratory conditions. In the choice and no-choice experiments, significantly greater numbers of eggs and living larvae, and greater mass of living larvae were found on
U. carpinifolia
and
U. carpinifolia
var.
umbraculifera
compared to those on the other tree species. In the choice experiment, oviposition did not occur on
F. rotundifolia
subsp.
persica
. There were a few eggs on
P. alba
but no living larvae. The mean mass of living larvae was lowest on
P. orientalis
. In addition, in the no-choice experiment significantly fewer numbers and mass of living larvae were found in
P. alba
and
F. rotundifolia
subsp.
persica
. In the larval insertion experiment, more larvae survived on
U. carpinifolia
and
U. carpinifolia
var.
umbraculifera
compared to the other trees. Larvae recovered from
U. carpinifolia
and
U. carpinifolia
var.
umbraculifera
weighed significantly more than larvae from the other trees. These results suggest that
U. carpinifolia
and
U.
carpinifolia
var.
umbraculifera
are the most preferred and suitable hosts for SLB adults and larvae.
Salix alba
is an acceptable host for adult oviposition and a potentially suitable host for larval development.
Platanus orientalis
and
P. alba
are less suitable, and
F. rotundifolia
subsp.
persica
appeared to be unsuitable as a host for SLB. |
