“…This can be explained by the fact that T. triangulare is a self-pollinated crop but there is the tendency of the population to be heterogenous due to their floral propensity for insect pollinations (Gill, 1988). In habitats where pollinators are available, the species is likely to show mixed mating system involving both cross-pollination as a result of floral visitors and autogamy by perianth closing (Shivanna, 2019). Such a mechanism gives the species resilience under pollinator constraint as a means of reproductive assurance (Kalisz and Vogler, 2003;Eckert et al, 2006Eckert et al, , 2010Shivanna, 2014Shivanna, , 2015 Flowers of T. triangulare are actinomorphic and of open type; any floral visitor is able to harvest the reward (Pellmyr, 2002).…”

Talinum triangulare is an herbaceous succulent plant eaten as a vegetable throughout the tropics including many countries in West and Central Africa and are an essential ingredient in traditional dishes. Experiments were made on the plant to examine the influence of foraging behavior of flowering insect on pollination and yields of this plant species in 2018 and 2019 at Bafut. Observations were made on 1615 to 4055 flowers per treatment. The treatments included unlimited floral access by visitors and bagged flowers to deny all visits. The study focused on the foraging behavior of flowering insects and their pollination activity (fruiting rate). The results show that 14 insect species visited waterleaf flowers and Camponotus flavomarginatus was the most frequent (33.20%). Insects foraged throughout the day light period. Their activity was highest between 10 am and 12 pm. Insect species foraged the flowers for pollen and nectar. The fructification rate of unrestricted floral access was significantly high than that of protected flowers to deny all visits. The maintenance of insect nest close to T. triangulare field is recommended to improve it fruits production.
