Physical Basis of Insect Repellency [PDF]
Nature, 1956 THE physical basis of insect repellency being unknown, the search for new repellents has had to be conducted on an essentially hit-or-miss basis. With the accumulation of evidence that the odours of substances may be correlated with the low-frequency, fundamental vibrations of their molecules1, it seemed worth while to examine the absorption of some ...

Host choice and host leaving in Rhopalosiphum padi (Hemiptera: Aphididae) emigrants and repellency of aphid colonies on the winter host [PDF]
, 2000 Host choice and winter-host leaving in emigrants of bird cherry–oat aphid, Rhopalosiphum padi (Linnaeus), were investigated in the laboratory. In settling choice tests, emigrants collected from the winter host, Prunus padus, preferred this plant over ...

Pest Management Science, EarlyView.Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

Microclimate modification and insect pest exclusion using agronet improve pod yield and quality of french bean [PDF]
, 2014 French bean [Phaseolus vulgaris (L.)] is among the leading export vegetable in Africa, mostly produced by small-scale farmers. Unfavorable environmental conditions and heavy infestations by insect pests are among the major constraints limiting production

Pest Management Science, EarlyView.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 ...

Pest Management Science, EarlyView.Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

Intercropping mitigates incidence of the oilseed rape insect pest complex
Pest Management Science, EarlyView.Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.
