Ladybird propylaeajaponica & harmonia axyridis , ground beetle pseudoophonus griseus and ant lion chrysopidae were dominant natural enemies migrating with insect pests 龟纹瓢虫propylaeajaponica &异色瓢虫harmoniaaxyridis ,步甲pseudoophonusgriseus和草蛉是伴随害虫迁飞的主要天敌。
But it really is doubly and trebly hard to have crowds and multitudes of people turning up after him i could have forgiven him , to take ladybird s affections away from me 可是成群结队的人来找他，要想把小鸟儿的感情从我这儿抢走，的确是令人双倍地难受，三倍地难受，尽管我可以原谅他。 ”
And so with solids such as a shell , a nut , a plum , a pear , a tadpole , a mushroom , a mountain peak , a kidney , a carrot , a tree - trunk , a bird , a bud , a lark , a ladybird , a bulrush , a bone 对于其他实体，如，贝壳、核桃、李子、梨子、蝌蚪、蘑菇、山峰、肾脏、胡萝卜、树干、鸟儿、花蕾、云雀、瓢虫、芦苇以及骨头也应这样来感觉。
Ladybird has learnt to know then that his mind is walking up and down , walking up and down , in his old prison . she hurries to him , and they go on together , walking up and down , walking up and down , until he is composed 后来小鸟儿体会到了他的心还在他当年的牢房里走着，走着，便匆匆赶到他面前，两人一起走，走呀，走呀，直走到他平静下来。
On sundays , miss pross dined at the doctor s table , but on other days persisted in taking her meals at unknown periods , either in the lower regions , or in her own room on the second floor - a blue chamber , to which no one but her ladybird ever gained admittance 星期天普洛丝小姐在医生的桌上用膳，别的日子总坚持在没人知道的时候到底层或二楼她的屋里去吃一一那是个蓝色的房间，除了她的小鸟儿之外谁也不许进入。
Fijiensis and myzus persicae ( sulzer ) . in order to investigate the influence of alternative preys on the ladybird , comparison between its alternative preys and natural prey bemisia tabaci ( gennidius ) was studied in the laboratory , and the results showed that the beetle could not oviposit when feeding exclusively on m . persicae , but the adult longevity was n ' t significantly changed compared with those feeding on natural prey ( 2 )小黑瓢虫分别以三种猎物为食时，均表现为雌虫的寿命大于雄虫的寿命， t测验表明，以蚜虫为猎物时，雌雄成虫寿命之间的差异达到极显著水平；以红蜘蛛为猎物时，雌雄成虫寿命之间无显著差异；以烟粉虱为猎物时，雌雄成虫寿命之间的差异达到显著水平。
The relationship among searching efficiency ( e ) , the prey density ( n ) and the adult ladybird density ( p ) was simulated as e = 0 . 3 1 10 / ( 0 . 7842 + 0 . 000404 n + 0 . 21 58 p ) by beddington ' s model e = at / [ 1 + athn + btw ( p - 1 ) ] , i . e . the searching efficiency declined when the adult ladybird and the prey densities increased . in the single predator - two preys system , the selective predation of the adult female beetle to both eggs of b . tabaci and t . nr . fijiensis was discussed when two preys coexisted 当两种猎物共存时，在不同总猎物密度下，测定了捕食者对各猎物的喜好性和转换行为，分析了两种猎物共存时，小黑瓢虫雌成虫对各猎物的功能反应形式，结果表明:当两种猎物共存时，小黑瓢虫雌成虫对烟粉虱卵在低密度下不表现喜好性，而在中等密度和高密度下表现正喜好性，对红蜘蛛卵在各密度下均不表现喜好性;对烟粉虱卵的转换效应会由于总猎物密度的不同而呈现不同的效应，而对红蜘蛛卵则在各总猎物密度下均呈现负转换效应。
