Social parasitism involves one species relying on another to raise its young. Among vertebrates, the best known social parasites are such birds as cuckoos and cowbirds; the female lays egg in a nest belonging to another species and leaves it for the host to rear.

The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores.

In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed-species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases.

The true extent of the Polyergus ants' dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen.

Of the approximately 8,000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants.

What does the author mean by stating that “The dulotic species of ants...are the supreme social parasites” (line5)?

A. The Polyergus are more highly developed than the Formica

B. The Formica have developed specialized roles

C. The Polyergus are heavily dependent on the Formica

D. The Formica do not reproduce rapidly enough to care for themselves

Giải thích: The dulotic species of ants, however, are the supreme social parasites … To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores.

Dịch nghĩa: Các loài kiến, tuy nhiên, là những ký sinh trùng xã hội tối cao ... Để bù đắp cho những thiếu hụt, Polyergus đã trở nên chuyên về lấy những công nhân từ chi liên quan Formica để làm những công việc nhà.

Như vậy có thể suy ra rằng tác giả nói kiến là loài kí sinh tối cao vì loài Polyergus phụ thuộc năng nề vào loài Formica.

Phương án C. The Polyergus are heavily dependent on the Formica = Polyergus phụ thuộc rất nhiều vào Formica; là phương án chính xác nhất.

A. The Polyergus are more highly developed than the Formica = Chi Polyergus đang phát triển cao hơn chi Formica.

All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores

In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed-species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases

The true extent of the Polyergus and dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen

Of the approximately 8000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants

Tạm dịch: Các con bị bắt giữ sau đó được nuôi nấng bởi các con kiến thợ Formica cho tới khi sự xuất hiện của những con nhộng phát triển để thêm vào dân số của Formica, cái duy trì sự hỗn hợp loài. Kiến thợ Formica tìm kiếm đồ ăn và đưa nó cho các thành viên của cả hai loài. Chúng cũng loại bỏ chất thải và đào các buồn mới vì dân số tăng lên.
