Controlled pollination in field cages is used at the United States Department of Agriculture - Agricultural Research Service North Central Regional Plane Introduction Station (NCRPIS) for seed increase of several plane species. Honey bees, Apis mellifera L., have been used almost exclusively for several years. Recently we began investigating other pollinating insects for controlled pollination. 0smia cornifrons (Radoszkowski), a solitary bee imported from Japan, has been an excellent early-season pollinator. We placed domiciles of these bees in backyards of the NCRPIS staff to aid us in providing adequate numbers of bees for use in field cages the following growing season. …

Pollination of species of Brassicaceae for seed increase at the USDA-ARS North Central Regional Plant Introduction Station (NCRPIS) has been accomplished for several years by using nucleus hives of honey bees, Apis mellifera L., in field cages. Brassicaceae are cool season crops that need pollination from late April to early June in the north temperate zone. Overwintered hives of honey bees need time to strengthen (i.e., increase their numbers) and thus it is difficult to make enough nuclei to meet our early season pollinations needs. Purchasmg package bees from suppliers in the southern U.S. is an expensive alternative. In this …
