oa Journal of the Entomological Society of Southern Africa - Investigations into the use of a trap crop to protect cotton from attack by Lygus vosseleri (Heteroptera: Miridae)

Four known favoured host plants of Lygus vosseleri were considered as possible trap crops to protect cotton from this pest. In three successive years field trials were done using Cissus adenocaulis as the trap crop. When treated with insecticide to prevent the development of a Lygus population on it, this plant gave considerable protection to the cotton. For various reasons sorghum and Pseudarthria hookeri were considered to be unsuitable. Salvia coccinae was used in a small field trial for protection against nymphal damage. The results obtained did not warrant further investigation.
