Barley exposed to aerial allelopathy from thistles (Cirsium spp.) becomes less acceptable to aphids
Abstract.  1. Recent studies have shown that plant–plant interaction via chemicals (allelopathy) can affect insects. Here the effects on aphid acceptance of barley after exposure to volatiles andExpand

Airborne interactions between undamaged plants of different cultivars affect insect herbivores and natural enemies
This study investigated the effects of airborne interaction between different barley cultivars on the behaviour of bird cherry-oat aphid Rhopalosiphum padi, the ladybird Coccinella septempunctata andExpand

Herbivory by a Phloem-Feeding Insect Inhibits Floral Volatile Production
There is extensive knowledge on the effects of insect herbivory on volatile emission from vegetative tissue, but little is known about its impact on floral volatiles. We show that herbivory byExpand

Chemical interaction between undamaged plants--effects on herbivores and natural enemies.
Most research on plant-plant chemical interactions has focussed on events following herbivore or pathogen attack. However, undamaged plants also interact chemically as a natural facet of theirExpand

Olfactory learning of plant genotypes by a polyphagous insect predator
Olfactory learning may allow insects to forage optimally by more efficiently finding and using favourable food sources. Although olfactory learning has been shown in bees, insect herbivores andExpand

Infection with an insect virus affects olfactory behaviour and interactions with host plant and natural enemies in an aphid
Aphid ecology and population dynamics are affected by a series of factors including behavioural responses to ecologically relevant chemical cues, capacity for population growth, and interactions withExpand

Test of semiochemicals and a resistant wheat variety for Russian wheat aphid management in South Africa
Abstract:  Aphid behaviour‐modifying semiochemicals were tested against Russian wheat aphid Diuraphis noxia in South African wheat. Volatile substances from plant essential oils, methyl salicylate,Expand

Multivariate statistics coupled to generalized linear models reveal complex use of chemical cues by a parasitoid
Understanding how animals integrate multiple cues, in particular complex mixtures of volatile chemicals, is a subject of current interest. Insect behavioural responses to volatile blends haveExpand

Volatile Exchange between Undamaged Plants - a New Mechanism Affecting Insect Orientation in Intercropping
Changes in plant volatile emission can be induced by exposure to volatiles from neighbouring insect-attacked plants. However, plants are also exposed to volatiles from unattacked neighbours, and theExpand

Identification of mosquito repellent odours from Ocimum forskolei
BackgroundNative mosquito repellent plants have a good potential for integrated mosquito control in local settings. Ocimum forskolei, Lamiaceae, is used in Eritrea as a spatial mosquito repellentExpand
