Abstract

The role of visit of pollinator insect(Chalicodoma cincta) on the production of Bean (Phaseolus vulgaris, Rose variety),were studied at Sarh in September 2021 and 2022. The experiments were made on four treatments. The activity behavior of Chalicodoma cincta on the flower were appreciated to determinate is impact on the yield. Results indicate that among seven insect species recorded on flowers, C. cincta ranked first (31.41%) and harvested nectar. Throughout the importance of the flower visit, this insect provoked a significant increase of the podding rate (30.45 %), the mean number of seeds per pod (22.42 %) and the percentage of normal seeds (32.81%). The conservation and installation of C. cincta nests close the plantation fields is recommended to improve pod production.
