Public ISBD Titre de série : Samaru Research bulletin Titre : The effect of plant spacing on the number of Aphids trapped over the groundnur crop Type de document : texte imprimé Auteurs : ABrook, J. Année de publication : 1968 ISBN/ISSN/EAN : CI-03126 Note générale : Aphis craccivora, Aphis gossypi and longiumguis were trapped at 3ft above ground more often over widely-spaced groundnuts. A crop height A. craccivora and A. gossypi shaved a simular but greather response to plant spacing. Numbers af phopolosiphum midis and tetranenra Nigriabdominalis caught were not by groundnut spacing differences. All Aphis species studied exept T. Nigriabdominalis responded to yelow, but their sensitivity to colour was less during the dry season. It is suggested that the effect of plant spacing on number caught is not due to color alone, but perhaps, also to be contrasts of plants and soil is widely spaced groundnuts. A crop height an alighting response is shown only by those species that feed on groundnuts. The control of rosette desease of groundnuts by early planting and colose spacing appears to be due the inhibition of the landing responses in A crossivora by the continuous ground cover resulting from thre treatements.
