Abstract

Native bee pollinators were collected and observed on cultivated blueberry, raspberry, and cranberry and on natural non-cultivated plants such as blackberry, buttercup, fireweed, thistle, and hairy cat's ear. Higher abundance and diversity of native bees were found on natural vegetation than on berry crops. Native bee populations on berry crops increased from 1981 to 1982, although diversity was similar. Native bees were not abundant enough to ensure adequate pollination of berry crops, and therefore, the use of managed honey bees is advisable. Pesticide impact, competition with managed honey bees, and habitat destruction have probably decreased native bee populations in agricultural areas of the Fraser Valley.

The use of a standard measure of native pollinator abundance, bees observed/min/m2, is recommended for future studies of this kind.

Résumé

Les abeilles pollinisatrices sauvages ont été prélevées et observées sur des cultures de bleuets, de framboisiers et de canneberges, ainsi que sur des plantes non cultivées dont le mûrier, le bouton d'or, l'épilobe, le chardon et l'oreille de chat. La densité et la diversité des abeilles sauvages étaient plus élevées sur la végétation naturelle que sur les cultures de petits fruits. Les populations d'abeilles sauvages sur les petits fruits ont augmenté de 1981 à 1982, quoique la diversité était similaire. Les abeilles sauvages n'étaient pas assez abondantes pour assurer une pollinisation adéquate des cultures de petits fruits de sorte que l'utilisation d'abeilles domestiques est à conseiller. Les effets des pesticides, de la concurrence par les abeilles domestiques et de la destruction des habitats ont probablement réduit les populations naturelles d'abeilles dans les régions agricoles de la Vallée du Fraser.

L'utilisation d'une mesure standard de l'abondance des pollinisateurs naturels, exprimée en abeilles/min./m2, est recommandée pour les futures études de ce genre.
