Conteúdo: 	This study aimed to evaluate the amount of visits of the main insect
pollinators during flowering period in orchards of three Japanese pear cultivars and
at two different locations and years with different climates in southern Brazil:
Caçador (CD) and São Joaquim (SJ). During the flowering period, at 9 am and
3 pm, three trees of each cultivar were randomly chosen and the number of
potentially pollinating insects per tree was quantified for a period of 3 min. In
Caçador, the number of bees was also quantified on the ruderal plants inside the
orchard. The highest numbers of flower visits were observed in the afternoon
(3 pm), although the amount of pollinating insects in pear, both in the warmer
climate region (CD) as in the colder climate region (SJ), is considered low according
to the literature. Ruderal plants (white clover and dandelion, among others) with
high sugar content in nectar and which grow between the tree rows attract more
honey bees than pear tree flowers. In São Joaquim, in the first evaluation year, we
did not detect significant nectar secretion and pollinating insects were only attracted
to flowers by its pollen. It is necessary to install a larger number of honey bee hives
per area to improve adequate pollination in pear orchards.
