| 中文摘要: |
| 调查发现我国雷州半岛菠萝洁粉蚧Dysmicoccus brevipes的天敌有4科8种，其中香港角毛瓢虫Horniolus hisamatsui Miyatake、丽草蛉Chrysopa formosa Brauer及一种瘿蚊Aphidoletes sp是优势天敌。香港角毛瓢虫Hhisamatsui、细毛小瓢虫Scymnus (Pullus) syoitii Sasaji为广东新记录种。香港角毛瓢虫Hhisamatsui捕食菠萝洁粉蚧的量随猎物密度的增大而增加，且随着龄次的增加而增加，但当猎物密度达到一定程度后，其增长率就随猎物密度的增大逐渐减缓，即捕食量与猎物密度为逆密度制约关系，呈负加速曲线，以Holling(1959）圆盘方程进行模拟的结果是属于Holling-Ⅱ型。香港角毛瓢虫1龄、2龄、3龄、4龄幼虫和成虫对菠萝洁粉蚧2 龄若虫的理论最大捕食量分别为1153头/天、2611头/天、6173头/天、7042头/天、7407头/天。 |
| 英文摘要: |
| There are more than 8 species of natural enemies of Dysmicoccus brevipes in Leizhou Peninsula, and the main natural enemies are Chrysopa formosa Brauer, Horniolus hisamatsui Miyatake, Scymnus(Pullus)tenuis Yang and Aphidoletes sp, and Hhisamatsui & S(P)syoitii are reported the first time in Gunagdong provinceThe functional and interfering response of Horniolus hisamatsui Miyatake to Dbrevipes was carried out in condition of laboratoryThe simulated result of disk equation showed that their functional response is fit to HollingⅡtypeThe predating number increased with the density of the Dbrevipes and the maximal predation numbers of 1st, 2nd, 3rd, 4th instar larva and adult of Hhisamatsui were 1153, 2611, 6173, 7042, and 7407 per day respectivelyThe searching efficiency decreased as the beetle density increased |
