Nesting rate of Osmia conifrons was most effective in case of using 1,000 bamboo tubes trap with 1,000 individuals of Osmia conifrons. This result shows using pollinating insect, Osmia conifrons, directly to increase the multiplication rate in field condition is more effective than other method not using it. General type of nest is lower in efficacy of nesting rate than specific type of nest designed with dark thick cover in apple orchards. But its result needs some further examination in same condition.
