Alternative Host Plants of Clavigralla tomentosicollis Stal(Hemiptera:Coreidae), the Pod Sucking Bug of Cowpea in the Sahelian Zone of Burkina Faso

Abstract:
Refuge plants, by offering egg laying and feeding substratum to bugs could be potential reservoirs from where adult bugs responsible of primary infestation in cowpea fields would spread in rainy season. Studies were carried out in the three phytogeographic zones of Burkina Faso to identify host plants of Clavigralla tomenstosicollis populations, the pest of cultivated cowpea, in dry season. Theses studies in the residual herbaceous, shrubby and arboreal vegetation enabled the identification of 24 herbaceous plants hosting at least one of the development stages (eggs, larvae, adults) of the bug in dry season. These plants are divided into eleven families, the Fabaceae family being the most important. However, six legume species, Cajanus cajan (L.), crotalatia retusa (L.), crotalaria sp., Rhynchosia memnonia (Del.), R. minima and R. orthobothrya seem to be the most frequent alternative hosts. Throughout the dry season, bug eggs and/or larvae or adults were observed, indicating a likely continuous insect reproduction in the absence of cowpea. This study discusses the importance of knowing the plants on which bug residual populations spend dry season for the appropriate development of an integrated control method.
