Abstract

A previous study indicated that Eumegachile pugnata may be managed for pollination of sunflower. Additional field studies show that females prefer to nest in deep holes along the margins of nesting units (wooden blocks with holes containing drinking straws). More nests were made in units placed in dense rows of unthinned sunflower plants than were made in units placed at the field margin. An 8-fold increase in the field population was obtained in hybrid plantings and less than 1% of the bee cells were destroyed by nest associates. Mortality of immature stages differed within nesting units; egg mortality in nests constructed near edges exposed to long periods of sunlight was higher than in nests made in protected areas of the unit.
