Pod wall trichomes and resistance of two wild cowpea, Vigna vexillata, accessions to Maruca testulalis (Geyer) (Lepidoptera: Pyralidae) and Clavigralla tomentosicollis Stal (Hemiptera: Coreidae)



Pod wall trichomes and resistance of two wild cowpea, Vigna vexillata, accessions to Maruca testulalis (Geyer) (Lepidoptera: Pyralidae) and Clavigralla tomentosicollis Stal (Hemiptera: Coreidae)



Bulletin of Entomological Research, 794: 595-605



Experiments were conducted to investigate the role of pubescence in the resistance of 2 wild cowpea (Vigna vexillata) varieties, TVNu 72 and TVNu 73, to feeding and damage caused by 2 cowpea (V. unguiculata) pests, Maruca testulalis and Clavigralla tomentosicollis. The fine structure of the trichomes was also studied by electron microscopy in order to try to determine the role played by trichomes in the resistance of these varieties to both pests.
