Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

Ecological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

Ecological Entomology, EarlyView.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

Detection of Volatile Constituents from Food Lures by Tephritid Fruit Flies

Insects, 2018
Tephritid fruit flies require protein for sexual and gonotrophic development. Food-based lures are therefore widely used in strategies to detect and control fruit flies in the Tephritidae family.

Mate choice by males: glass Y-olfactometer.

, 2013
A male was given a simultaneous choice between two cockroaches in retention, one in each small vial placed at the extremities of the olfactometer. A pump drew clean controlled air through a large vial containing calling females (emitting volatile sex ...

Oviposition Behaviour, Nymphal Development and Below‐Ground Olfactory Preference of Pentastiridius leporinus on 12 Beta vulgaris Genotypes

Journal of Applied Entomology, EarlyView.
ABSTRACT The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the primary vector of two phloem‐restricted prokaryotes, which can cause the disease syndrome de basses richesses (SBR) in sugar beet (Beta vulgaris L.). Heavy infestations of this insect have contributed to significant yield losses in Central Europe, but little is known about ...

Reactivating a Relaxation Exercise During Sleep to Influence Cortical Hyperarousal in Individuals With Frequent Nightmares

Journal of Sleep Research, EarlyView.
ABSTRACT High‐frequency EEG activity during sleep, reflecting cortical hyperarousal, has recently been incorporated into aetiology models of nightmares. However, its precise role remains insufficiently understood because experimental approaches to manipulate hyperarousal during sleep are limited.

Differential behaviour of Anopheles gambiae sensu stricto (Diptera: Culicidae) to human and cow odours in the laboratory. [PDF]

, 2001
A dual port olfactometer was used to study the response of Anopheles gambiae Giles sensu stricto to odours of human and animal origin. Human odour consisted of human skin emanations collected on a nylon stocking, which was worn for 24 h.

Rhizobacterial Modulation of Maize Defense Alters Herbivore Performance and Parasitoid Behavior

Plant, Cell &Environment, EarlyView.
ABSTRACT The association between plants and beneficial soil microorganisms can profoundly influence aboveground trophic interactions, yet these effects are often context‐dependent. Although plant growth‐promoting rhizobacteria (PGPR) are increasingly used in maize production, little is known about how these microorganisms affect maize defenses against ...

Chemosensory Event-Related Potentials in Response to Nasal Propylene Glycol Stimulation

Frontiers in Human Neuroscience, 2019
Propylene glycol, also denoted as 1.2 propanediol (C3H8O2), often serves as a solvent for dilution of olfactory stimuli. It is supposed to serve as a neutral substance and has been used in many behavioral and electrophysiological studies to dilute pure ...
