초록
The pear sucker (Cacopsylla pyricola) is the most important insect pest in Korea. The hatching rates of overwintered adults laid eggs were observed at 10, 13, 18, and 22℃. The liner model was draw as Y=0.00277X+0.00146(Y=developmental rate, X=temperature) about temperature and developmental rate to eggs. The developmental threshold temperature to eggs was assumed about -0.83℃. The egg hatching timing over 50% as the accumulated temperature by day maximum temperature 6℃ over from 1st February in 2008, 2009 and 2011 was 429.7, 417.6, and 424.3 degree ℃, respectively, was 3 to 7days before full blooming in pear orchard. On the other hand, the abamectin 1.8EC, lime sulfer, machine oil and 13 kinds of eco-friendly materials were not shown the control effect to the eggs. To mixed stage of pear sucker, the eco-friendly materials over 90% control value were 4 kinds such as a mixture of Azadiractin A+B, Nimbin, Salanin, Meliantriol and Vepol after twice application as 21st May and 5th June in pear growing season, in 2012.
Abstract

The liner model was draw as Y=0.00277X+0.00146(Y=developmental rate, X=temperature) about temperature and developmental rate to eggs. The developmental threshold temperature to eggs was assumed about -0.83℃. The egg hatching timing over 50% as the accumulated temperature by day maximum temperature 6℃ over from 1st February in 2008, 2009 and 2011 was 429.7, 417.6, and 424.3 degree ℃, respectively, was 3 to 7days before full blooming in pear orchard.
