毒液之力

蜇伤

毒液通过蜇刺出来。

它的毒液会造成什么？

The venom works on the cockroach's nervous system. The first sting causes short paralysis of the front legs, and the second sting, into the brain, stops the cockroach from escaping and makes it groom and move sluggishly. The effect lasts for about 72 hours.1

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

如果它蜇人

刮掉蜜蜂的蜇针，冷敷患处。
如果这个人呼吸困难、脸或喉咙肿胀，或感觉要晕倒，这是过敏急症：拨打急救电话，如果他们有肾上腺素笔就使用。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

The wasp stings a cockroach twice, aiming for specific nerve clusters in its body and head, rather than just injecting venom at random.1

After stinging, the wasp leads the cockroach to its burrow by pulling on one of its antennae, like a leash, even though the wasp is too small to carry it.1

The stung cockroach can still walk, swim and flip over, but it loses its normal urge to escape.1

The larva eats the cockroach's internal organs over about 8 days, and the adult wasp later emerges from the dead cockroach's body.1

A single mating is enough for a female to parasitise several dozen cockroaches.1

The wasp was brought to Hawaii in 1941 as a biological control, but this did not work well because of the wasp's territorial behaviour and the small scale on which it hunts.1
