Elsevier BIOBASE is a comprehensive database of worldwide biological
research. The file is very current with many records available
online within three weeks after receipt of the original journal.
Each document is indexed using a unique versatile classification
scheme which is updated annually to adapt to changing research
trends. Approximately 273,000 records are added each year, 70% of
which contain an abstract.
ELBI covers the following areas:
- Applied microbiology and biotechnology
- Cancer research
- Cell & developmental biology
- Clinical chemistry
- Ecological & environmental sciences
- Endocrinology and metabolism
- Genetics and molecular biology
- Immunology and infectious diseases
- Neuroscience
- Plant science
- Protein biochemistry
- Toxicology
Use ELBI to answer questions such as:
- what is the role of neuropeptides in the migration of
adenocarcinoma cells in vitro and in vivo?
- how does fever affect sleep?
- what is published on the genetic modification of wheat?
- how are bacteria used to clean contaminated soil?
- what techniques are there for identifying abnormalities in
chromosome morphology?
- how is malolactic fermentation stabilised in the production of
wine?

Abstract
1.Chrysophtharta bimaculata is a native chrysomelid species
that can cause chronic defoliation of plantation and regrowth
Eucalyptus forests in Tasmania, Australia. Knowledge of the
dispersion pattern of C. bimaculata was needed in order to
assess the efficiency of an integrated pest management (IPM)
programme currently used for its control. 2. Using data from
yellow flight traps, local populations of C. bimaculata adults
were monitored over a season at spatial scales relevant to
commercial forestry: within a 50-ha operational management
unit (a forestry 'coupe') and between coupes. In addition,
oviposition was monitored over a season at a subset of the
between-coupe sites. 3. Dispersion indices (Taylor's Power
Law and Iwao's Mean Crowding regression method) demonstrated
that C. bimaculata adults were spatially aggregated within
and between coupes, although the number of egg-batches laid at
the between-coupe scale was uniform. Spatial autocorrelation
analysis showed that trap-catches at the within-coupe level
were similar (positively autocorrelated) to a radius distance
of approximately 110 m, and then dissimilar (negatively
autocorrelated) at approximately 250 m. At the between-coupe
scale, no repeatable spatial autocorrelation patterns were
observed. 4. For any individual site, rapid changes in beetle
density were observed to the associated with loosely
aggregated flights of beetles into and out of that site. Peak
adult catches (> the weekly mean plus standard deviation trap-
catch) for a site occurred for a period of 2.0 +/- 0.22 weeks
at a time (n = 37), with normally only one or two peaks per
site per season. Peak oviposition events for a site occurred
on average 1.4 +/- 0.11 times per season and lasted 1.5 +/-
0.12 weeks. 5. Analysis of an extensive data set (n = 417)
demonstrated that adult abundance at a site was positively
correlated with egg density, but negatively correlated with
tree damage (caused by conspecifics) and the presence of
conspecific larvae. There was no relationship between adult
abundance and a visual estimate of the amount of young foliage
on trees. 6. Adults of C. bimaculata are shown to occur in
relatively small, mobile aggregations. This means that pest
surveys must be both regular (less than 2 weeks apart) and
intensive (with sampling points no more than 150 m apart) if
beetle populations are to be monitored with confidence.
Further refinement of the current IPM strategy must recognize
the problems posed by this temporal and spatial patchiness,
particularly with regard to the use of biological insecticides
such as Bacillus thuringiensis, for which only a very short
operational window exists.
