Insect pollination of Anacardium occidentale L., Mangifera indica L., Blighia sapida Koenig and Persea americana Mill.
and
Flowers of all four tropical crops studied in Jamaica (cashew, Anacardium occidentale L. mango, Mangifera indica L., akee, Blighia sapida Koenig, and avocado, Persea americana Mill.), were visited by many Polistes wasps but these were not such efficient pollinators as the less numerous honeybees. In Jamaica and Kenya, mango and cashew were often relatively unattractive to honeybees compared with other crops nearby. In Kenya, no wasps but numerous ants visited cashew and mango flowers. Bagging flowers of cashew and mango to prevent insect pollination, diminished set. The proportion of hermaphrodite flowers, yield and set of cashew, mango and akee varied greatly from tree to tree.
