Statistical Inference for Olfactometer Data
SummaryOlfactometer experiments are used to determine the effect of odours on the behaviour of organisms such as insects or nematodes, and typically result in data comprising many groups of small overdispersed counts. We develop a non-homogeneous Markov chain model for data from olfactometer experiments with parasitoid wasps and discuss a relation with

Testing Performances of a Newly Designed Olfactometer [PDF]
Dynamic dilution olfactometry as regulated by EN 13725 requires instrumentation of adequate technology and in order to spread the use of Dynamic Olfactometry high usability of the device is a must.

Host-associated chemical cues mediating host-finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis. [PDF]
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...

Host plant-specific volatiles of Beauveria bassiana-colonized plants initiate trophic plant-aphid-predator cascades. [PDF]
Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

From Factory to Field: Sex Pheromone of Plutella xylostella Produced in Yeast Cell-Factories Validated in Laboratory and Field Trials [PDF]
Plutella xylostella (L.) (Lepidoptera: Plutellidae), the diamondback moth (DBM), is a cosmopolitan pest of brassicas. To validate and compare the performance of yeast-derived sex pheromone components with chemically synthesized ones, we studied the ...

Herbivore-induced volatiles were extracted from fresh healthy jasmine plants (Jasminum sambac L.) and infested jasmine plants damaged by two-spotted spider mite, Tetranychus urticae and analyzed through Gas Chromatography-Mass spectrometry (GC-MS) to ...

Several types of olfactometers have been used to evaluate mosquito responses to agents that mimic natural volatiles that repel or attract. The Y-tube olfactometer has been widely used to study repellents and attractants, while the high-throughput ...

Natural Repellents as a Method of Preventing Ant Damage to Microirrigation Systems
Ants are important because they damage agricultural equipment, including microirrigation systems. The aim of this research was to assess the efficiency of the incorporation of repellents in drip irrigation tubing as a method of protection against ant ...

Volatile cues can play a significant role in the location and discrimination of food resources by insects. Dung beetles have been reported to discriminate among dung types produced by different species, thereby exhibiting behavioral preferences. However,

The pentatomid bug Bagrada hilaris is a key pest of brassicaceous crops in several areas of the world. Previous studies suggest that mate location of this species is mediated by volatile chemicals produced by males, among which the main compound is (E)-2-
