| 7. | 9 . the foraging behavior of e . balteatus de geer larvae changes gradually at different aphid densities . when the aphid density changed from low to high , the 在猎物密度低时,搜索活动提高,处置时间较高;在猎物密度高时,搜索活动则下降,处置时间较低。 |

| 9. | 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。 |
| 10. | It is believed that the search behavior of the third instar larva of e . balteatus de geer is extensive search before feeding , and is area - concentrated search after feeding . 8 . contacting with aphid , eating an aphid and contacting with agar block with aphid body fluid on it can arouse searching behavior of e . balteatus de geer larva from extensive search to area - concentrated search , and contacting with agar block can not 8 .明确了和蚜虫接触、完全取食1头蚜虫及和沾有蚜虫体液的琼脂块接触等食物刺激均可激发黑带食蚜蝇幼虫搜索行为由广域型转换为地域集中型,而和琼脂块接触则不能刺激其搜索行为转换。 |
