Yeast biocontrol agents that were applied to 'Bose' and 'Anjou' pears in the field up to three weeks prior to harvest were found to survive on the fruit at high population levels on both pear varieties. Cryptococcus infirmo-miniatus, Cryptococcus laurentii, and Rhodotorula glutinis maintained populations averaging 5 x 10⁶ cfu/fruit...
The biology and behavior of the codling moth, Cydia pomonella (L.), was studied to
determine factors responsible for differences in susceptibility to moth damage among apple
and pear cultivars.
In release experiments, codling moth adults were intercepted in significantly greater
numbers in host (apple, pear) than in non-host (maple) trees,...
There was a linear relationship of [alpha]-amylase activity
from 2 to 12 hours incubation in both freeze-dried and fresh
'd'Anjou' pear fruit tissue. Activity was greater, however,
in fresh as compared with freeze-dried tissues. [alpha]-Amylase
activity from both types of samples was not detected until
60 minutes incubation. After 90...
