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. | As a consequense of eutrophication , chironomid larvae excessively propagates in water sources , such as reservoir and fresh lake , which induced the 1st instar larvae of chironomid in source water to enter drinking water treatment system
水体富营养化使得摇蚊幼虫在水库、湖泊类水源中大量孳生繁殖,直接导致其可以在给水处理系统中出现。 |
| 9. | 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。 |
| 10. | In the laboratory when the first - instar larvae , third - instar larvae , and fifth - instar larvae of cotton bollworm fet with all kinds of tissues of transgenic bt cotton , the result showed that transgenic bt cotton can easily cause death to low - instar larvae and this effect deteriorates on high - instar larvae
转bt基因棉对棉铃虫幼虫的行为活动有较大的影响，表现为取食时间明显减少，静息、吐丝下垂和爬行时间明显延长。棉铃虫幼虫取食转bt基因棉后，发育速度的减慢导致其生育期的延长。 |
