| 1. | 7 . the searching behavior of the third instar larva of e . balteatus has been studied
黑带食蚜蝇幼虫的捕食行为过程一般是：搜索?捕捉?取食?清洁?休息?搜索。 |
| 2. | The predaceous syrphid fly , episyrphus balteatus de geer is one of the significant predators for the control of aphides
黑带食蚜蝇episyrphusbalteatusdegeer幼虫是控制多种蚜虫的主要天敌之一。 |
| 3. | At present , the mainly studying of foraging behavioural ecology is about ladybird and lacewing , and less about aphidophagous hoverfly
目前，对捕食性昆虫捕食行为生态学的研究主要集中在瓢虫和草蛉，而有关捕食性食蚜蝇捕食行为生态学的报道几乎没有。 |
| 4. | The total rectilinear distance from food to stops is significantly longer and the searching area covered by the larvae is 3 - 12 times larger before feeding than after feeding
黑带食蚜蝇幼虫取食后的搜索速度、直线距离和领域范围搜索面积均显著小于取食前。 |
| 5. | The daily maximum number of m . avenae preyed theoretically by the first , second and third instar larva of e . balteatus are 5 . 13 , 26 . 00 and 119 . 26 aphids respectively . 2
黑带食蚜蝇1龄、 2龄和3龄幼虫对麦长管蚜的日最大捕食量分别为5 . 13头、 26 . 00头和119 . 26头。 |
| 6. | The functional response of the first , second and third instar larvae of e . balteatus preying on macrosiphum avenae ( f . ) show the rolling ii type with better fitting
黑带食蚜蝇各龄幼虫对麦长管蚜macrosiphumavenae ( f . )的捕食功能反应用holling ?型和新holling ?型功能反应模型拟合均较好。 |
| 7. | There are mutual interference among the third instar larvae of episyrphus balteatus de geer , and the searching efficiency decreases and the intensity of scrambling competition increases with increase of its density
黑带食蚜蝇3龄幼虫存在着种内干扰，其寻找效应随着自身密度的增加而降低，其分摊竞争强度随着自身密度的增加而增加。 |
| 8. | The searching speed in 0 - 15 , 15 - 30 , 30 - 45 , 45 - 60 and 60 - 75 seconds before feeding is 1 - 4 times quicker than that after feeding , which varies very little before feeding , but the longer the time is after feeding , the quicker the searching speed is
确定了黑带食蚜蝇幼虫的搜索行为可由取食前的广域型搜索向取食后的地域集中型搜索转换。 |
| 9. | In this paper , predation , starvation endurance ability , foraging behavior of e . balteatus and the effect of different aphides on its growth and development , have been studied . the main results are as follows : 1
本文研究了黑带食蚜蝇的捕食行为、搜索行为及激发因子、饥饿耐受性、功能反应、捕食作用及影响因素、不同猎物对黑带食蚜蝇生长发育的影响等。 |
| 10. | The best searching densities of the first , second and third instar larva of e . balteatus are 6 . 73 , 10 . 09 and 44 . 03 aphids respectively . 3 . the predation ratio of e . balteatus is the lowest at 14 ? and the predation ratio at 18 c , 22 c , 26 c and 30 c are not different
黑带食蚜蝇1龄、 2龄和3龄幼虫对麦长管蚜的最佳寻找密度分别为6 . 73头、 10 . 09头、 44 . 03头，这对田间利用黑带食蚜蝇幼虫防治麦长管蚜有一定参考价值。 |
