Insect host location: a volatile situation.
Locating a host plant is crucial for a phytophagous (herbivorous) insect to fulfill its nutritional requirements and to find suitable oviposition sites. Insects can locate their hosts even though theExpand

Intercropping increases parasitism of pests
As part of a programme for controlling lepidopteran stem-borers in cereal crops in Africa, we have investigated the effectiveness of combined cropping regimes of cultivatedand wild plants forExpand

Exploiting chemical ecology and species diversity : stem borer and striga control for maize and sorghum in Africa
Stem borers, comprising the larvae of a group of lepidopterous insects, and parasitic witchweeds, particularly Striga hermonthica and S asiatica, cause major yield losses in subsistence cerealExpand

Identification of Semiochemicals Released During Aphid Feeding That Attract Parasitoid Aphidius ervi
Herbivore induced release of plant volatiles mediating the foraging behavior of the aphid parasitoid Aphidius ervi was investigated using the pea aphid, Acyrthosiphon pisum, feeding on broad bean,Expand

The role of volatile semiochemicals in mediating host location and selection by nuisance and disease‐transmitting cattle flies
Abstract.  The role of volatile semiochemicals in mediating the location and selection within herds of Holstein‐Friesian heifers by nuisance and disease‐transmitting cattle flies was investigatedExpand

The Chemical Ecology of Aphids
Insects are sensitive to chemical aspects of their environment, particularly with regard to host and mate location. Aphids can select individual or a few closely related host plant species from aExpand

Aphid alarm pheromone produced by transgenic plants affects aphid and parasitoid behavior
The alarm pheromone for many species of aphids, which causes dispersion in response to attack by predators or parasitoids, consists of the sesquiterpene (E)-β-farnesene (Eβf). We used high levels ofExpand

Control of Witchweed Striga hermonthica by Intercropping with Desmodium spp., and the Mechanism Defined as Allelopathic
During investigations into the control of insect damage to maize crops in subsistence farming in Kenya, which involved intercropping with repellent plants, the fodder legumes silverleaf (DesmodiumExpand

Maize landraces recruit egg and larval parasitoids in response to egg deposition by a herbivore.
Natural enemies respond to herbivore-induced plant volatiles (HIPVs), but an often overlooked aspect is that there may be genotypic variation in these 'indirect' plant defence traits within plantExpand

Integrated pest management: the push–pull approach for controlling insect pests and weeds of cereals, and its potential for other agricultural systems including animal husbandry
This paper describes the ‘push–pull’ or ‘stimulo-deterrent diversionary’ strategy in relation to current and potential examples from our own experiences. The push–pull effect is established byExpand
