Insect host location: a volatile situation.
TLDR
Paired or clustered olfactory receptor neurons might enable fine-scale spatio-temporal resolution of the complex signals encountered when ubiquitous compounds are used.
Exploiting chemical ecology and species diversity : stem borer and striga control for maize and sorghum in Africa
TLDR
There has been considerable take-up of the system within the communities where farmer-managed trials have been carried out, particularly in the Trans Nzoia and Suba districts of Kenya, and the programme is set to expand throughout and beyond Kenya.
Identification of Semiochemicals Released During Aphid Feeding That Attract Parasitoid Aphidius ervi
TLDR
Volatiles obtained by air entrainment of aphid infested plants were more attractive to A. ervi than those from uninfested plants, in both behavioral bioassays and activity of pure compounds, which significantly increased parasitoid responses to these compounds.
Identification of Human-Derived Volatile Chemicals that Interfere with Attraction of Aedes aegypti Mosquitoes
TLDR
The results indicated that higher levels of specific compounds may be responsible for decreased “attractiveness” of individuals, and unattractiveness of individuals may result from a repellent, or attractant “masking,” mechanism.
Habitat Management Strategies for the Control of Cereal Stemborers and Striga in Maize in Kenya
TLDR
The integrated ’push-pull’ strategies were shown to increase parasitism of stemborers through attraction of parasitoids to one of the intercrops, molasses grass, which drastically reduced damage to maize by the parasitic weed, striga.
The role of volatile semiochemicals in mediating host location and selection by nuisance and disease‐transmitting cattle flies
TLDR
Evidence is provided for the hypothesis that the natural differential attractiveness within herds of Holstein‐Freisian heifers, i.e. a single host species, for cattle flies is partly due to differences in volatile semiochemicals emitted from the host.
Control of Witchweed Striga hermonthica by Intercropping with Desmodium spp., and the Mechanism Defined as Allelopathic
TLDR
During investigations into the control of insect damage to maize crops in subsistence farming in Kenya, the fodder legumes silverleaf (Desmodium uncinatum) and greenleaf were found to reduce dramatically the infestation of maize by parasitic witchweeds such as Striga hermonthica.
The Chemical Ecology of Aphids
TLDR
Study of aphid chemical ecology involving volatile semiochemicals, particularly pheromones, has been greatly enhanced by the development of electrophysiological rccordings from aphid antennae, using the electroan­ tennograph (EAG) and single-cell recording (SCR) methods.
Aphid alarm pheromone produced by transgenic plants affects aphid and parasitoid behavior
TLDR
The transformation of a plant to produce an insect pheromone is reported and it is demonstrated that the resulting emission affects behavioral responses at two trophic levels.
Response of economically important aphids to components of Hemizygia petiolata essential oil.
TLDR
It was shown that minor components in the oil caused inhibition of the alarm response for M. persicae and A. pisum, and the grain aphid, Sitobion avenae F, was not only repelled by (E)-beta-farnesene but also by (-)-germacrene D.
