Analysis of Volatiles Induced by Oviposition of Elm Leaf Beetle Xanthogaleruca luteola on Ulmus minor
Egg deposition of the elm leaf beetle Xanthogaleruca luteola causes the emission of volatiles from its food plant, Ulmus minor. These volatiles are exploited by the egg parasitoid, Oomyzus gallerucae, to locat...

Chemical Polymorphism of the Cuticular Lipids of the Cabbage White Pieris rapae
The epicuticular composition of different body parts of the Cabbage White, Pieris rapae L., was investigated using GC and GC/MS. The major group of components, hydrocarbons, occurs in two distinct classes, which ...

Chemical Analysis of Volatiles Emitted by Pinus sylvestris After Induction by Insect Oviposition
Gas chromatography – mass spectrometry analyses of the headspace volatiles of Scots pine (Pinus sylvestris) induced by egg deposition of the sawfly Diprion pini were conducted. The odor blend of systemically ovip...

Benzoic Acid Derivatives in a Hypogastrurid Collembolan: Temperature-Dependent Formation and Biological Significance as Deterrents
Two phenolic acids were identified in the collembolan Ceratophysella denticulata: 3-hydroxy-4,5 dimethoxy benzoic acid and 4-hydroxy-3,5-dimethoxybenzoic acid (syringic acid). These are localized on or in the int...

The Chafer Pheromone Buibuilactone and Ant Pyrazines are also Produced by Marine Bacteria
Headspace extracts obtained from agar plate cultures of two marine bacteria from the North Sea (Germany), Loktanella strain BIO-204 and Dinoroseobacter shibae strain DFL-27, were analyzed by GC-MS. Several γ-lact...

(Z)-Pentacos-12-ene, an Oviposition-deterring Pheromone of Cheilomenes sexmaculata
Larvae of the coccinellid beetle Cheilomenes sexmaculata (F.) produce an oviposition-deterring pheromone that inhibits egg laying of conspecific females on oviposition sites walked over by first-instar larvae. By...

Chemical Ecology of Fruit Bat Foraging Behavior in Relation to the Fruit Odors of Two Species of Paleotropical Bat-Dispersed Figs (Ficus hispida and Ficus scortechinii)
We investigated the fruit odors of two bat-dispersed fig species in the Paleotropics, in relation to the foraging behavior of fruit bats, to test the following hypotheses: 1) fruit odor plays a critical role f...

An Antiaphrodisiac in Heliconius melpomene Butterflies
Gilbert (1976) suggested that male-contributed odors of mated females of Heliconius erato could enforce monogamy. We investigated the pheromone system of a relative, Heliconius melpomene, using chemical analysis,...

Fine Tuning of Social Integration by Two Myrmecophiles of the Ponerine Army Ant, Leptogenys distinguenda
Myrmecophiles are animals that live in close association with ants and that frequently develop elaborate mechanisms to infiltrate their well-defended host societies. We compare the social integration strategie...

Defense by Volatiles in Leaf-Mining Insect Larvae
The defense strategy of an insect toward natural enemies can include a trait that appears at first sight to contradict its defensive function. We explored phylogeny, chemistry, and defense efficiency of a pecu...

Pheromone-based Mating and Aggregation in the Sorghum Chafer, Pachnoda interrupta
Adults of the sorghum chafer, Pachnoda interrupta Olivier (Coleoptera: Scarabaeidae: Cetoniinae), form aggregations during the mating period in July, but also in October. The beetles aggregate on food sources, e....

An arthropod deterrent attracts specialised bees to their host plants
Many bee species are adapted to just a few specific plants in order to collect pollen (oligolecty). To reproduce successfully, it is important for oligolectic bees to find and recognise the specific host flowe...
