温度对锯谷盗成虫水平和垂直运动分布的影响
Influence of temperature on moving and distribution of Oryzaephilus surinamensis (Linnaeus) adults on flat surface and in vertical wheat column
摘要
Abstract
To make sure the movement of Oryzaephilus surinamensis on flat solid surface and vertical grain column with different temperature,the moving speed of O.surinamensis adults was monitored and observed on flat surface of paper and wheat bulk as well as in wheat column.And the movement and distribution were checked in wheat column in which temperature was in several ranges from 40 to 13 ℃separately.The results indicate that the initial moving temperature of O.surinamensis adults was 12 ℃both on flat surface of paper and wheat bulk.And then the moving speed increased with the temperature going up.The regression equation between moving speed and temperature was y =13.09x-18.79for the adult crawling on paper surface.That regression equation was y =3.939x-5.307 for the insect walking on the wheat surface.The adults walked faster on paper than on the wheat bulk.The adult movement in vertical wheat column was also related to temperature.There was a little insect moving when the temperature was below 11 ℃.Above 15 ℃ the moving speed went up with the temperature increasing.The moving up speed of the insect in uniform temperature grain column was faster than that of moving down of that.The distributed individuals of adult in the column with temperature gradient was concentrated in the part of wheat where temperature was 22 to 34 ℃.There was no distinct difference in moving speed in the range of 19 to 34 ℃.There was observably slower speed of ()(d)t moving when the temperature was above 37 ℃ and less than 19 ℃.关键词
