The bee mites Varroa jacobsoni Oudemaris and Euvarroa
sinhai Delfinado and Baker (Family Varroidae) are reported
for the first time from Thailand. V. jacobsoni was found
parasitizing colonies of Apis cerana indica F. and A. mellifera
L., E. sinhai was observed in association with drones
of A. florea F.

'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...
Workers in colonies of European honey bees Apis mellifera L. clean their
nestmate's body by allogrooming behavior. This behavior may be initiated by
either grooming dancers or by the allogroomers themselves. The first occurs
less frequently (ca. 17 %) than the later (83 %). By using the inner edge of...
The early stages of secondary succession of the
McDonald and Paul Dunn State Forests, Corvallis, Oregon,
were grouped into three stages; herb, herb-shrub, and
shrub, based on vegetation types. Flowers of herbaceous
species and residual shrubs dominated in the early years
after clear-cutting. Woody plants became increasing
abundant in the...
The biology of the two external Acarapis mites of honey bees,
Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler
was studied. It was observed that both Acarapis species have similar
developmental period (8-9 days) with males emerging earlier than
females.
Mite load and infestation rate of A. dorsalis decreased as bees...
Aspects concerning the bionomics of the parasitic honey bee brood mite, Varroa
jacobsoni Oudemans were investigated. Mite mortality is great during the winter season
when the host colony is not rearing brood, appearing to be independent of the mortality of
its host. In winter period, no significant association between the...
Honey bees mark artificial flowers with scents that
advertise about the previous history of the flower to
subsequent foragers. Unrewarding flowers are marked with a
scent, after a single visit, that makes the flower less
attractive to subsequent foragers. Previously rewarding
flowers are initially less attractive than unvisited
flowers but...
