In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation.

拟寄生物 （parasitoid）也称 類寄生生物 、 捕食寄生生物，在 演化生态学 中，是一种以宿主为代价，与宿主密切相关，最终导致宿主死亡的生物。 拟寄生 （parasitoidism）是介于 寄生 和 捕食 之间的一种中间性种间相互关系，其特征是对宿主的致命预后，这使得该策略接近于捕食。 拟寄生物一般仅见于 昆虫，其于幼虫期寄生 宿主 体内，后期将宿主杀死，成虫时自由生活；成蟲多半會利用 產卵管 將卵注入至宿主體內。 寄生蜂 就属于一种拟寄生昆虫 [1]。 拟寄生物可以用来进 …

Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts.

The meaning of PARASITOIDISM is a relation existing between various insect larvae and their hosts in which the larva feeds upon the living host tissues in an orderly sequence such that the host is not killed until the larval development is complete.

2021年3月5日 · Parasitodism is a form of parasitism involving a parasitoid organism. Certain insect species are parasitoids. An example is a wasp ovipositing into the body of an alfalfa aphid. Taking this as an example, the parasitoid wasp requires that its parasitic developmental (larval) stage is spent within the alfalfa aphid host.

2004年6月22日 · It is an insect whose larvae develop by feeding on the bodies of other arthropods; like a parasite they require just a single host to complete their development, but like a predator they invariably kill their host. The female parasitoid never builds a nest or cache, as do some related insects.

Parasitoid, an insect whose larvae feed and develop within or on the bodies of other arthropods. Each parasitoid larva develops on a single individual and eventually kills that host. Most parasitoids are wasps, but some flies and a small number of …

Predation, herbivory, and parasitism are specific types of antagonistic interactions. In predation, one organism kills and consumes another. Predation provides energy to prolong the life and...

兼性寄生虫（facultative parasite）是主要在外界营自生生活，但在某种情况下可侵入宿主营寄生生活的动物。 如 粪类圆线虫 （Strongyloides stercoralis）（成虫）既可寄生于宿主肠道内，也可以在土壤中营自生生活。 兼性寄生虫既可营自生生活，又能营寄生生活，如 粪类圆线虫 （成虫）既可寄生于宿主肠道内，也可以在土壤中营自生生活。 寄生虫指一种生物，将其一生的大多数时间居住在另外一种动物，称为宿主或寄主上，同时，会造成被寄生动物的危害称之。 兼性寄生虫 …

2021年6月11日 · 拟寄生（parasitoidism）是寄生的一种形式。拟寄生者在寄主体上或体内产卵，通常引起寄主死亡。 重寄生现象 hyperparasitism系指寄生物再寄生于寄生物的现象。
