什么是蠓蝇-你如何控制它们?

You’ve probably experienced hopelessly swatting at a swarm of flies while trying to enjoy a sunny day outside, 而且你远不是唯一一个. Each summer – or even year-round if you’re in a warmer climate such as Texas or Florida – midge flies can become a major nuisance wreaking havoc on property and recreational time and driving residents away from outdoor resources.

但是，什么是蚊子苍蝇? 你怎样才能在你的财产上减少它们?

什么是蚊蛉或“盲蚊”?

蠓是指几种小型的非蚊类苍蝇. 更具体地说，最常见的蠓包括蚊科 Chironomidae (虫), 幽蚊科 (幻蚊)在这个顺序 双翅目 (指所有苍蝇).

现在, 换一种更有用的说法, 蠓很小, dainty flies (although some species can be bulkier) with one pair of long, 狭窄的翅膀, 和长, 瘦腿. Males tend to have feathery antennae used to hear the high-pitched sounds emitted by the female’s wings.

While midges are usually found near naturally occurring lakes and 池塘 in small, 所的水平, the abundance of nutrients within stormwater systems acts as a beacon to breeding midges and they can reproduce in vast quantities. 这就是他们成为社区问题的时候.

蠓和蚊子有什么区别?

蠓和蚊子经常被误认为是同类, 这说得通，因为它们都属于同一阶 双翅目 (尽管它们的幼虫控制是 非常不同的). The largest difference between the two is that mosquitoes have a 长鼻, 口器用来咬和吸血的口器. 蠓不会，也不会咬人.

Otherwise, most of the differences visible to the eye are found in the fine details.

蠓有以下特点:

• When landed, fold their first leg pair in a ‘prayer’ position (which can be mistaken for antennae)
• 长期以来, 睑板 前腿的足部
• 翅膀上没有鳞片，使它们光滑

蚊子 具有以下特点:

• 落地后，将第二腿/后腿举在空中
• 有鳞片状的翅膀，翅尖上有淡淡的流苏
• 通常不会形成蜂群

哪里可以找到蠓?

Midges deposit their eggs near waterbodies, often stillwater boggy marshes or stormwater 池塘. Because of this, their adult counterparts are generally also found in these same areas.

It’s also common to see midges in big swarms or ‘clouds’ in the air, often around dusk (some people in the south refer to these as ‘gnat-balls’). This can be when a lot of people 或社区 residents become irritated or frustrated by their presence.

In terms of geography, midge flies can be found almost any在哪里. 但是在南方的一些州, 比如佛罗里达或德克萨斯, 它们温暖的气候使种群全年繁荣.

蠓会咬人吗?

值得庆幸的是, 事实上，蠓并不叮咬人类, they only live for a few weeks at most and thus rarely eat anything in their adult stage beyond nectar, 果汁或糖水. They can land and crawl around the skin, which many find irritating and unwanted.

为什么蚊子不断出现?

Part of what makes midges so difficult to control is their ongoing lifecycle that starts in 池塘, 湖泊，雨水系统和陆地末端. 蠓的生命周期分为四个阶段, starting as eggs laid on a waterbody’s surface before sinking into the muck. 这些卵孵化成幼虫, 取决于物种, either borrow further into the sediment or swim freely through the water. The larvae develop into pupae before emerging as fully formed, flying adults. 这个持续的过程可能只需要两到三周.

That means that if you’re trying to control midges by just combating the adult ones flying around, 鸡蛋里还有很多, 幼虫和蛹阶段, 准备好继续这个循环了.

如何控制蚊蚋?

T在这里 are plenty of reasons to get rid of or control the midge flies in your area. Not only are they annoying when they swarm around waterfronts, 池塘, 湖滨, 或码头, but they can also cause property damage on painted or wooden surfaces.

Most bug sprays don’t go far in terms of keeping individual midge flies away, and they certainly are powerless against swarms or heavily populated areas near waterfronts, 船, 或海岸线. 虽然有助于暂时减轻蠓的数量, pesticides alone won’t solve the problem in the long term as midges continuously breed and migrate from nearby waterbodies.

而不是, 在乐虎网, 我们建议采用一种综合的方法，结合化学, 生物, and preventative methods to keep midges away while also working to control the population. 要了解更多乐虎网我们如何处理下面的问题，请点击 在这里.

1. 监测 – take samples of midges to identify which are present and estimate their population levels (as well as to figure 在哪里 他们来自).
2. 减轻营养 – midges are attracted to stormwater 池塘 in particular as they have tons of weeds and algae as well as nutrient-rich waters from runoff – things larvae feed on. 但是有一些方法可以安全地减少这些, as well as making sure water stays circulating rather than still and stagnant.
   1. 曝气系统，以保持水的不断运动
   2. 沿海/岸线种植以吸收流失的养分
   3. 控制藻类，改善整体水质
3. 生物防治 – sometimes the addition of certain fish, which feed on the midges, can act as a natural control. Make sure that this fish species and the amount is estimated by someone with experience – adding the wrong fish, 数量错误, 或者添加到错误的水体中可能会产生不利影响.
4. 化学防治 – done mainly to reduce annoyance; these may include larvicides applied to waterbodies, ULV adulticide, 壁板和树叶的屏障处理, 或更多的.
