**赤眼蜂屬**（學名：）是膜翅目細腰亞目寄生蜂下目之下的小蜂总科赤眼蜂科的成員之一，其物種皆為多食性（英语：）的微小拟寄生物，寄生於其牠昆蟲的蟲卵中。赤眼蜂屬是赤眼蜂科約80個屬的其中一個，在全世界包括超過200個物種。成蟲大多小於1毫米，會產卵於宿主卵内，幼蟲取食卵黄、化蛹並引發宿主死亡。成蟲羽化後咬破寄主卵殼而出。

儘管現時在全世界有多種用於生物防治的物種，本屬物種仍然是研究得最詳盡的一類，有超過一千份相關的文獻與本屬物種相關，也是目前世上於生物防治中 最常用的物種。 *Trichogramma* spp. are unique in approaching the size limit of how small an insect can be, which would be determined by how few neurons they can fit in their central nervous systems, yet exhibiting a complex behavior to sustain their lives. These wasps have less than 10,000 neurons, which is 1/100th that of the next smallest insect.

寄生性
---

雌性成虫会通过化学和视觉信号来找到用来作为宿主的卵，比如卵大小和颜色。在她找到合适的卵后，其将会试图通过她的产卵器和对卵壳的敲击来判别这个卵是否之前已经被寄生过了。雌性赤眼蜂也会通过敲击来判别目标被寄生卵的大小和质量以决定赤眼蜂在被寄生卵内的产卵数量。一个雌性赤眼蜂一天最多可以在十个被寄生卵上产卵。

辨識
--

本屬物種體型細小，構造上亦單一，使物種間的分辨頗困難。由于雌性相对来说体型较小，分类学家一般通过辨别雄性触角和生殖器的方式来辨别不同物种。

Charles V. Riley在1871年于北美第一种对赤眼蜂属下的物种进行描述。他将从总督蝶卵中爬出来的小蜂称为*Trichogramma minutum*。在生物分类学中，首个采集的标本是十分重要的，因为其被用作继续描述这个物种的基础，但是它丢失了。Riley后来在1879年又描述了第二种叫做*Trichogramma pretiosum*的赤眼蜂，但是其样本也丢了。为了更正这些错误，昆虫学家返回了Riley原本找到这两个物种的地方并收集了新的范本。现在这些范本被完好地存放在美国史密森尼学会。当前赤眼蜂属的物种超过两百种，但是在1960年的时候只有大概40种赤眼蜂被描述。

赤眼蜂屬物種體內的沃尔巴克氏体
---------------

赤眼蜂屬物種體內有沃尔巴克氏体（*Wolbachia*），是一種分佈廣泛的細菌，專門感染昆蟲的內臟，特別是生殖系統的器官。這些沃尔巴克氏体在感染了昆蟲後，會改變其宿主交配時的成功率。
Through a series of manipulations, *Wolbachia-*infected hosts transmit this intracellular bacterium to uninfected individuals. These manipulations include male killing (increasing ratio of infected females that can reproduce), feminization (males become fertile females), 单性生殖, and cytoplasmic incompatibility（英语：）. Horizontal transfer of parthenogenesis-inducing *Wolbachia*, which has been observed in *Trichogramma* wasps, causes infected females to asexually produce fertile females and nonfunctional males. The effects of this include potential speciation of *Trichogramma*, if *Wolbachia* is maintained long enough for genetic divergence to occur and for a new species of asexual wasps to become reproductively isolated.

Transmission of the bacterium through horizontal transfer has been observed within the same species and among different species of *Trichogramma*, including *T. kaykai*, *T. deion, T. pretiosum,* and *T. atopovirilia*; however, limitations to transmission exist. *In vitro* successful horizontal transfer is uncommon within *Trichogramma*, which suggests that the density of *Wolbachia* must be relatively high inside of the hosts' ovaries. Cytoplasmic incompatibility of the host and bacterium can also be the source of this unsuccessful transfer in-vitro. These limitations *in vitro* suggest that in nature, horizontal transfer by parthenogenesis-inducing *Wolbachia* may be a difficult and rare phenomenon. However, when looking at the *Wolbachia*-host associations, the *Trichogramma-Wolbachia* form a monophyletic group based on several *Wolbachia*-specific genes, which may be explained by horizontal transfer of *Wolbachia* between different species. Therefore, although interspecific horizontal transfer of *Wolbachia* is limited *in vitro*, it is likely to occur quite frequently in nature and is not well understood yet.

The effects of *Wolbachia* in *Trichogramma* have several evolutionary implications. Commonly, uninfected wasps are unable to breed with infected wasps. Many generations of reproductive isolation of these different groups may result in speciation. In addition, some hosts can evolve with a dependency on *Wolbachia* for core reproductive functions, such as 卵子生成, so that eventually an infection is a requirement for successful reproduction. Finally, *Wolbachia* can influence gender determination in its hosts so that more females are successfully born. This results in a reversal in 性選擇, where females must compete for male mates, which has evolutionary implications as it exposes different phenotypes to natural selection.

Biological control
------------------

*Trichogramma* spp. have been used for control of lepidopteran pests for many years. They can be considered the *Drosophila* of the parasitoid world, as they have been used for inundative releases and much understanding today comes from experiments with these wasps.

Entomologists in the early 1900s began to rear *Trichogramma* spp. for biological control. *T. minutum* is one of the most commonly found species in Europe and was first mass reared in 1926 on eggs of *Sitotroga cerealella（英语：）*. *T. minutum* has been investigated as a method of biological control of the *Choristoneura fumiferana*, a major pest of spruce and fir forests.

Nine species of *Trichogramma* are produced commercially in insectaries around the world, with 30 countries releasing them. *Trichogramma* wasps are used for control on numerous crops and plants; these include cotton, sugarcane, vegetables, sugarbeets, orchards, and forests. Some of the pests controlled include cotton bollworm (*Helicoverpa armigera（英语：）*), codling moth (*Cydia pomonella*), lightbrown apple moth (*Epiphyas postvittana（英语：）*), and European corn borer (*Ostrinia nubilalis（英语：）*).

*Trichogramma* species vary in their host specificity. This can lead to nontarget hosts being parasitized. This, in turn, can cause problems by reducing the amount of parasitism of the target host, and depending on the rate of parasitism, nontarget effects could be significant on nontarget host populations. Research is being done on the use of *Trichogramma* wasps to control populations of spruce bud moth (*Zeiraphera canadensis（英语：）)*, which damages white spruce trees.

### Species used

The most commonly used species for biological control are *T. atopovirilia*, *T. brevicapillum*, *T. deion*, *T. exiguum*, *T. fuentesi*, *T. minutum*, *T. nubilale*, *T. platneri*, *T. pretiosum*, and *T. thalense*.

*T. pretiosum*
--------------

*T. pretiosum* is the most widely distributed species in North America. It is a more generalized parasitoid, able to parasitise a range of different species. It has been the focus of many research studies and has been successfully reared on 18 genera of Lepidoptera. *T. pretiosum* was introduced into Australia in the 1970s as part of the Ord River Irrigation Area IPM scheme.

*T. carverae*
-------------

*Trichogramma carverae* is mainly used for light brown apple moth and codling moth control, and is predominately used in orchards. In Australia, *T. carverae* is used for biological control of light brown apple moth in vineyards. Though Australia has its own native *Trichogramma* species, not much work has been undertaken to use them commercially for biological control within Australia.

Light brown apple moth is common throughout Australia and is polyphagous on more than 80 native and introduced species. The larvae cause the most damage, especially to grape berries, as their feeding provides sites for bunch rot to occur. Losses in the crops can amount up to $2000/ha in one season. It is very predominant in areas such as the 雅拉河谷. Insecticide use is not a choice method for most growers, who prefer a more natural means of controlling pests. As a result, *Trichogramma* wasps were considered a good candidate for biological control, even more so as the moth larvae are difficult to control with insecticide. Moreover, light brown apple moths are relatively vulnerable to egg parasitism, with their eggs being laid in masses of 20-50 on the upper surfaces of basal leaves in grapevines.
