Cane, Daniel Schiffhauer, Linda J. Kervin] The leaf-cutting bee Megachile addenda Cresson is an effective and potentially manageable pollinator of cultivated cranberries, Vaccinium macrocarpon Aiton. This facultatively gregarious, univoltine bee excavates shallow subterranean nests in the dikes and periodically flooded sand beds of commercial cranberries in southern New Jersey. Females provision 1—2 leaf-lined nest cells per day, each containing 3.9—5.4 million pollen tetrads (1992 and 1993 means, respectively) collected from a calculated minimum of 1,076—1,207 cranberry flowers. Using their middle and hind legs, pollen-foraging females repeatedly stroked the 8 poricidal anthers of a virgin cranberry flower, removing 71% of the pollen while leaving an average stigmatic load of 28 tetrads (0.6% of pollen harvested). An estimated 1,291—1,440 berries should result from the daily foraging activity of a female, calculated using either pollen or time as currencies. In weather favorable for bee activity, an estimated 1,114 nesting females per hectare of cranberry bed could suffice to produce a commercial fruit set. Management of M. addenda for cranberry pollination must include control of its cleptoparasite Coelioxys immaculata Cockerell, which can parasitize >90% of nest cells when abundant. © 1996 Entomological Society of America Ecology and Population Biology nationallicence Megachile nationallicence cranberry nationallicence pollination nationallicence nesting biology nationallicence foraging nationallicence Cane James H. aut Schiffhauer Daniel Ocean Spray Cranberries, Chatsworth, NJ 080.19. aut Kervin Linda J. aut Annals of the Entomological Society of America Oxford University Press 89/3(1996-05-01), 361-367 0013-8746 89:3<361 1996 89 aesa https://doi.org/10.1093/aesa/89.3.361 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/aesa/89.3.361 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Cane James H. aut NATIONALLICENCE 700 1- Schiffhauer Daniel Ocean Spray Cranberries, Chatsworth, NJ 080.19 aut NATIONALLICENCE 700 1- Kervin Linda J. aut NATIONALLICENCE 773 0- Annals of the Entomological Society of America Oxford University Press 89/3(1996-05-01), 361-367 0013-8746 89:3<361 1996 89 aesa Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
