Laboratory test were made to value the validity of a new alternating
method of laboratory at EN 22 about the determination of the curative
action against larvae of Hylotrupes bajulus L. The changes proposed in
the new method affect fundamentaly the kind of wood specimen used in the
test. Greater percentages of mortality were obtained in the alternative
method, because the larvae were subjected to more drastic conditions than
in the original method. Some proposals to solve the defects observed in
the alternative method were explained.  Language SP.█LABORATORIO

Cerambycidae Coleoptera communication through support vibration
morphology and mechanics of the signal. Behav. Processes. 12 (2).
169-186. abstract-- The stridulation of Hylotrupes bajulus (L.) is
examined with respect to ethology and functional morphology. The
morphology outlines a defined species-specific structure. Biophysical
aspects of sound emission are discussed. The sound pattern of
stridulation is described. It time structure is species-specific. Only
the vibrational component of stridulation is an effective signal in the
intraspecific communication of H. bajulus. It is a part of aggressive
behaviour, where it constitutes menacing or impressing elements. It is
also found within the mating behaviour, where it forms a part of the
tactile stimulation of the female by the male beetle. The 'open'
organisation of the behaviour analysed is of interest. This open
arrangement of the behaviour is somewhat surprising in view of the
complex differentiation of the morphology. The specificity of the
ethological structures is discussed. Language EN.█INST

- Experiments were conducted at various locations in a air conditioned
room ( C) and in containers of Al, Cu, thick Fe and MU metal
as well as in a Helmholtz coil which largely compensated the vertical,
component of the geomagnetic field. Determined were: the lifespan of
termites kept without food; the reproduction of groups of Rhinotermitidae
(Microcerotermes championi Snyder, Coptotermes formosanus Shiraki,
Mastotermes darwininiensis Frogatt and Heterotermes indicola (Wasmann))
with neotenic reproductives and their gallery building activity; the
development of incipient colonies of Kalotermitidae (Neotermes jouteli
(Banks) and Incisitermes marginipennis (Latreille)); the number of
imagines and their development period of a Coleoptera (Lyctus africanus
Lesne) and lepidopteran species (Tincola biselliella Hum.) which were
observed from the time of egg laying (taking into accont the location of
the groups as well as the larval development of 2 other coleopteran
species (Stegobium paniceum L. and Hylotrupes bajulus (L.))). Results
differed according to location and metal container. They differed also
with regard to the developmental stages of the insects and the types of
experiments. When the geomagnetic field was changed to reduce its
horizontal component, development and egg production increased. An area
with an enlarged horizontal component and possibly another unknown field
deviation slowed development, and in 2 cases decreased egg production.
A compensation of the vertical component of the geomagnetic field partly
retarded development. An alternating magnetic field in the room
stimulated termite gallery building activity. Al and MU metal shieldings
slowed some developmental processes down. Because the differences in
results between the individual locations in the same room may be
considerable, it is imperative to consider these differences in future
tests. The influence of magnetic and electric fields on insect
development must be thoroughly investigated.  Language GE.█VON-LAUE-STR

a parasite of the old-house borer Hylotrupes bajulus. Z. Angew. Entomol.
88 (5). 520-527. abstract-- R. piceus Marsh. (Hymenoptera, Braconidae)
is a parasite of the old house borer, H. bajulus (L.). The body length
of the males is 1.2-3.5 mm, the females 2.8-4.6 mm and their stinger
2.5-5.5 mm. A female can kill and infest with eggs up to 4 Hylotrupes
larvae, but may paralyze even more individuals. Depending on the
ecological conditions, the lifetime of the females is 1-4 wk. Development
from egg-laying to the appearance of imagines, where time of larval
feeding is less than 1 /3, takes 23 days (average) at C. At
lower temperature it takes longer. The number of progency varies and
depends on the size of the Hylotrupes larva. The ratio of females to
males was 9:1, but may vary. Parthenogenesis produces males. Properties
of the species as a parasite of H. bajulus are discussed.  Language

respiration of old house borer larvae Hylotrupes bajulus Coleoptera:

consumption, growth and respiration by 3 weight classes of Hylotrupes
bajulus larvae, under 5 constant temperatures at constant relative
humidity, were studied. Wood consumption in all larval weight classes was
greatest in the temperature range of to C, and
significantly reduced below and above these temperatures. Growth rates
for small larvae were not significantly different among temperatures.
Medium and large larvae exhibited negative growth rates at and C. The effects of temperature were evident in low and high
respiration values for medium and large larvae at and C. Respiration rates were highest for small larvae.
Developmental rates of H. bajulus larvae are affected by extremes of
temperature; medium and large larvae are affected to a greater extent by
changes in temperature than small larvae. These results are in close
agreement with those obtained for other wood feeding Coleoptera with
similar life histories. Slow growth is associated with low consumption
index (CI) in wood feeding insects which require more than one year to
develop. The CI for H. bajulus larvae, which require 2-11 years to
develop, ranged from 0.042 to 0.600 mg/mg/day. Temperature was a major
factor in determining the CI. The CI values for H. bajulus are low when
compared to leaf feeding Coleoptera (0.97 mg/mg/day) with univoltine life

abstract-- The occurrence of a female sex pheromone in the house longhorn
beetle, H. bajulus (L.), was demonstrated in laboratory bioassays. Male
beetles recognized female wings within the close range of olfactory
orientation. After dorsal contact of virgin females of 3 days, pine wood
substrates proved to be scent-marked, as indicated by more frequent and
prolonged beetle visits. Tests based on male beetles without antennae
showed no corresponding bioactivity. The pheromone elicited
characteristic a behavior by the male, consisting of excited searching
as well as occasional copulation attempts with single wings.  Language

bajulus (L.) (Coleoptera: Cerambycidae): Identification and female
response. Experientia 51 (3). 270-277. Issn 0014-4754. abstract-- We
report here the identification of the long-range, male-produced sex
pheromone of the Old house borer Hylotrupes bajulus. Chemical analysis
of hexane extracts obtained by surface extraction from dissected
prothoracic glands and from headspace samples of the two sexes, revealed
male-specific compounds: (3R)-3-hydroxy-2-hexanone, 2-hydroxy-3-hexanone,
the diastereomeric diols (2R,3R)-2,3-hexanediol and
(2S,3R)-2,3-hexanediol, 2,3-hexanedione, as well as 1-butanol. In wind
tunnel bioassays we tested the influence of these male-specific compounds
from the prothoracal glands on the behaviour of unmated and mated
females. Specific behavioural sequences of the tested females (activity,
running behaviour, searching, cleaning, flying, extension of ovipositor)
were recorded. Unmated females were attracted by male beetles, headspace
extracts of males, synthetic blends of the major pheromone compounds as
well as by the components (3R)-3-hydroxy-2-hexanone, and the
diastereomeric diols. Hexane, female beetles and 2,3-hexanedione did not
attract unmated females. The reactions of mated females to male beetles
and headspace samples did not differ significantly from those of the
controls. The results of the bioassays show that the two-stage premating
behaviour is initiated by emission of a long-range sex pheromone from the
male prothoracal glands, which functions as an activator, attractant, and
possibly aphrodisiac for unmated females.  Language EN.█Lehrstuhl

- With decreasing vitality of the trees an increasing resistance of the
construction timber of spruce (Picea abies (L.) Karst.) and fir (Abies
alba Mill.) against house longhorn beetles can be considered which, at
least, manifests itself in a retardation of the development of larvae.
The conditions for the development of newly hatched larvae in supporting
construction elements can further be worsened by using spruce rather than
fir and, in general, by a sawcut which removes bast and outer,
nutrient-rich sapwood from the construction element. This measure is
particularly appropriate for the evidently still more susceptible pine

function of the ovipositor of Hylotrupes bajulus L. Coleoptera:
Cerambycidae. Mater. Org. (berl) 21 (1). 15-30. abstract-- The female
Hylotrupes bajulus has an elongated ovipositor comprised of the modified
abdominal segments 8 and 9, intersegmental membrane 8 /9, and a pair of
distal gonostyli. When not in use, the ovipositor is retracted within
abdominal segment 7. The 8th abdominal segment forms the proximal end of
the ovipositor. An internal apodeme attached to the base of the 8th
sternite allows for extension and retraction of the ovipositor. The
intersegmental membrane 8/9 can be elongated up to more than 24 mm and
allows egg-laying in cracks more than 30 mm deep. The 9th sternum is
split along the midline to form a pair of hemisternites. The gonostyli
are comprised of basal coxies and apical styli. Several types of sensory
receptors are located on the ovipositor. Segment 8 has long tactile hairs
and short trichoid sensilla; intersegmental membrane 8/9 has no visible
sensory receptors; segment 9 has campaniform sensilla and short trichoid
sensilla. The gonostyli have several types of sensory receptors,
including long tactile hairs, medium trichoid sensilla, short trichoid
sensilla, and basiconic sensilla. The general orientation of the female
before oviposition is guided by light and the odor of bicyclic terpenes.
On a suitable surface the cracks are probed with mechanoreceptors of the
9th segment. Cracks with rough surfaces are preferred which are 0.25 mm
to 0.16 mm wide at a depth of 20 mm. During oviposition, usually only the
intersegmental membrane and the 9th segment are in the crack. The tactile
hairs of the styli apparently control the placement of the eggs in the
crack. The eggs pass down the ovipositor in 3.3 to 11 seconds. The
ovipositor can be extended to a length of 35 mm.  Language EN.█DEP

use, the ovipositor is retracted within abdominal segment 7. An internal
apodeme attached to the base of the 8th sternite allows for extension and
retraction of the ovipositor. Intersegmental membrane 8/9 makes up half
the length of the ovipositor. The 9th sternum is split along the midline
to form a pair of hemisternites. The gonostyli comprise basal coxites and
apical styli. Segment 8 has long tactile hairs and short trichoid
sensilla; intersegmental membrane 8/9 has no visible sensory receptors;
segment 9 has campaniform sensilla and short trichoid sensilla. Gonostyli
have several types of sensory receptors, including long tactile hairs,
medium trichoid sensilla, short trichoid sensilla, and basiconic
sensilla. Long tactile hairs and campaniform sensilla are innervated by
a single dendrite, thus functioning as mechanoreceptors. Medium trichoid
sensilla are innervated by three dendrites, two of which extend into the
lumen of the receptor. Short trichoid sensilla are innervated by five
sensory neurons. Basiconic sensilla are innervated by 1-3 dendrites,
depending on type and location of the receptor. All three types of
sensilla function as contact chemoreceptors, and may provide information
on suitability of the oviposition substrate.  Language EN.█MOBAY CHEMICAL

entire prothorax is internally lined with a glandular matrix composed of
numerous heap-like complex glands. Each gland is divided into several
subunits ("pore field units"), which in turn are composed of a varying
number of glandular units. The glandular unit comprises a distal
voluminous glandular cell, a medial (intercalary) canal cell I, and a
minute canal cell II near the cuticle. The spindle-like, basally
constricted receiving canal of the gland cell leads into the long,
non-porous conducting canal, which, by a single cuticle canal, opens in
an external pore field, an aggregate of orifices of other such cuticle
canals. In varying numbers, these randomly arranged pore fields are
located in superficial pits that are distributed over nearly the entire
prothorax. The structure of these male sex pheromone glands is discussed

treatment insecticides in structural softwoods part i. chlorpyrifos.
Mater. Org. (berl) 26 (2). 81-93. abstract-- Rough-surfaced versus
smooth-surfaced wood has a significant effect on uptake and absorption
of chlorpyrifos (Dursban TC), with rough surfaces tending to absorb
liquid more readily. The effect of wood surface orientation may or may
not have a significant effect at reducing penetration of liquid
insecticides, excluding the possibility of direct runoff or dripping of
the liquid. Penetration of chlorpyrifos after 24 hours is significantly
greater in southern yellow pine than in northern hard pine, spruce, or
fir. Initial surface concentrations, vulnerable to volatile loss over
time, are lower in southern yellow pine; whereas concentrations below the
surface remain more stable for up to 52 months. Initial high surface
concentrations of less permeable woods, i.e. northern hard pine, spruce
and fir, are also lost by volatilization or chemical breakdown.
Below-surface concentrations in these woods generally start out at a low
level and remain low after six months. Two aspects of the biology of
Hylotrupes bajulus are considered when selecting a surface application
of an emulsion formulation of insecticide for treatment of limited
infestations. Because pine is a preferred food for H. bajulus larvae, and
because infestations are frequently not discovered until larvae are two
to three years old, remedial treatment of pine with a surface-applied
emulsion formulation of chlorpyrifos can remain effective until adult
emergence. Treatment of less permeable types of wood indicate an
effective control period of much shorter duration.  Language EN.█VA

borer (H. bajulus) is an important structural insect pest in eastern USA.
The larval stages of this longhorned beetle feed on the softwoods (pine,
fir and spruce) commonly used in building construction. This insect
spends several years in the larval stage. Adults emerge from infested
wood in early June and continue into July. Soon after mating the female
deposits several batches of eggs. The number of eggs laid per female is
about 175. The eggs hatch in about 9 days, and 1st-instar larvae
immediately bore into the wood. Larvae feed in the wood for 2-6 yr. The
pupal stage is initiated by a cool period. The full-grown larva tunnels
to the surface of the wood and cuts an oval hole, then retreats back into
the tunnel. The pupal period lasts 3-6 wk. The known distribution in
Pennsylvania shows numerous records in the eastern counties, and only a
few for central and western counties. The adult and immature stages are

Isatis tinctoria. Zeitschrift Fuer Naturforschung Section C Biosciences
49 (1-2). 44-48. abstract-- Tryptanthrin (1), indole-3-acetonitrile (2)
and p-coumaric acid methylester (3) were isolated from the aerial parts
of Isatis tinctoria L. The compounds show insecticidal and antifeedant
activity against termites (Reticulitermis santonensis), insect preventive
and control activity against larvae of the house longhorn beetle
(Hylotrupes bajulus) and fungicidal activity against the brown-rot fungus
(Coniophora puteana).  Language EN.█Lehrstuhl Org Chem I/2 NW II, Univ

Stengard, & Hansen, L. 1990. The effect of cold treatment conditions on
the pupation and emergence of the house longhorn beetle Hylotrupes
bajulus L. Coleoptera: Cerambycidae. J. Appl. Entomol. 109 (3). 243-246.
abstract-- The induction of metamorphosis in Hylotrupes bajulus by cold
treatment was investigated. Large larvae (weight 200-500 mg) were kept
under the following conditions: group A: 100 days at C; group
B: 56 days at C. Group A larvae emerged in shorter time after
the termination of the cold treatment period and showed greater
uniformity in emergence time as well as a higher proportion of
metamorphosis. A greater proportion of the large larvae (> 400 mg)
underwent metamorphosis. Female larvae were significantly larger than
male larvae of the same age. In terms of mass rearing efficiency, cold
treatment at C for 100 days is the preferred method.  Language
