Local host plant specialization in an
insect herbivore may be caused by numerous
factors, including host-specific
natural enemy pressures or a local lack
of suitable host-plant choices that are
available elsewhere in its range. Such
local specialization or "ecological monophagy",
for whatever reason, may reflect
reduced ability to behaviourally
accept or physiologically utilize other
allopatric hosts that are naturally used
elsewhere by the species. We tested this
feeding specialization hypothesis using
the Tasmanian subspecies of Macleay's
swallowtail butterfly, Graphium macleayanum
moggana (Papilionidae),
which uses only a single host-plant species,
Antherosperma moschatum (southern
sassafras, of the Monimiaceae). Further
north, this same butterfly species (G.
m. macleayanum) uses at least 13 hostplant
species from seven genera and four
families (Lauraceae, Rutaceae, Winteraceae,
and Monimiaceae). Our larval
feeding assays with G. m. moggana
from Tasmania showed that certain
Magnoliaceae and Lauraceae could support
some larval growth to pupation.
However, such growth was slower and
survival was lower than observed on
their normal southern sassafras host
(Monimiaceae). We also found that toxicity
of particular plant species varied
tremendously within plant families (for
both the Magnoliceae and the
Monimiaceae).

蜻 蜓 的 化 石 卵 : 回 顾 和 阐 释 = Fossil
ovipositions of dragonflies: Review and
interpretation. ( 英 文 ). Vasilenko D V;

2007, 41(11): 1156-1161 2 图 版 .
The paper deals with the stratigraphic
range and morphology of fossil formations
on plants interpreted as insect ovipositions.
Our analysis of the insect fossil
record has shown that the endophytic
ovipositions probably belong to the
Kennedyina and Triadophlebiina (in the
Paleozoic and Lower Mesozoic) and to
the Calopterygina (in the Upper Mesozoic
and Cenozoic).

Eodiscina 亚 目 = Trilobites of the suborder
Eodiscina from the Lower Cambrian
of the northeastern Siberian platform
(Khorbosuonka River section). ( 英

Journal, 2007, 41(6): 614-620 3 图 版 .
Trilobites of the suborder Eodiscina
from the Lower Cambrian section of the
Khorbosuonka River (Siberian Platform,
Olenek Uplift) are studied. The stratigraphic
distribution of these forms in the
section is shown Two new species, Hebediscus
sublongus sp. nov. and
Korobovia khorbosuonica sp. nov., are
described. This is the first occurrence of
the genus Korobovia on the Siberian
Platform. The new record provides additional
data on morphology and expands
the paleogeographic range of the genera
represented by the newly described species.
