Many wasps foraged for several hours on only one or two female flowers, repelling other wasps or honeybees that tried to visit them; hence their behaviour discouraged cross-pollination. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating. The male flowers has six thin yellow parianth leaves surrounding, six stamens and three nectors glands at the center. Both wind and insects are considered to be the main pollinating agents, among them baees are important. When the flower is developed, these ridges split open exposing the sticky surface of the stigma which is extended as three erect teeth. 2 This study was carried out from 1999 to 2001 in coconut plantations represented by five coconut ecotypes commonly found in Mexico. In dwarf palms and hybrids, the interval between the two phases is either nil or negligible, thereby increasing the chances for self-pollination.
