Ants are the most common insects on the planet, the largest number of insect species. Because of various kinds of ants are social life groups, in ancient times known as "ants". According tothe modern form of scientific classification, ants can be divided into two populations: ants andtermites
Some insects are harmless to human! Some ants! Even can do science experiments and can also make medicine!
Because ant species, is the largest number of insect species. Only China has identified the ant species are more than 600 kinds of.
The "notorious repute" termites are pests, as everyone knows the "thousands of miles of dikes, collapse in Yixue!" mainly refers to the termites, termite also damage trees and wood products.
In general, common indoor ants have a dozen, which is with the rapid development of city construction, change the original living conditions of ants, so that gradually adapt to the dense buildings, densely populated city environment, often invade inside buildings, foraging and damage. The harm of different ants, although each has its characteristics, but the ants are generally in our reproductive duty cave, is a cave, in search of food hazards.
Ant harm can be summarized as bite disturbance human, spreading germs, pollute the environment, damage to buildings.
Mainly displays in 2 aspects: one is the direct economic losses caused by grazing damage and pollution, two is transmitted by a variety of diseases and damage the indirect loss caused to human health.
Thus, some food in a certain ants eat, judge the ants to simple is the "benefit" and "harm" is not scientific, not enough to go upon, also not because of some ants have a certain effect on the said she was beneficial to mankind, it is necessary to analyze the.
We often see in the outdoor black ants, but also the biological chain is important one annulus,we discarded food garbage, debris, dead insect bodies and so on, if further digested without ants and other insects, our living environment will soon become rancid.
蚂蚁是地球上最常见的昆虫，数量最多的昆虫种类。由于各种蚂蚁都是社会性生活的群体，在古代通称“蚁”。据现代形态科学分类，蚁可分两大种群：蚂蚁类和白蚁类有的对人类是害虫!有的蚂蚁却无害!甚至可以做科学实验!还有的还可以做药材! 因为蚂蚁的种类繁多，是数量最多的昆虫种类。仅我国国内已确定的蚂蚁种类就有600多种。 其中“臭名昭著”的白蚁是大害虫，众所周知的“千里之堤，溃于蚁穴!”主要是指白蚁，白蚁还破坏树木及木制品。 一般在室内常见的蚂蚁有十几种，这也是随着城市建设的迅速发展,改变了蚂蚁原有的生存条件,使之逐渐适应了建筑密集、人口稠密的城市环境,常侵入建筑物内部觅食和为害。不同蚂蚁的危害虽各有其特点,但蚁后一般都深居穴内司繁殖之职,主要是工蚁出穴寻食造成危害。 蚂蚁的危害可总结为咬扰人体、传播病菌、污染环境、损坏建筑。 主要表现在2个方面:一是因食害和污染所造成的直接经济损失,二是由传播多种疾病和危害人类健康所导致的间接损失。 由此可见，以某一种蚂蚁吃的某种食物，来简单的判断蚂蚁是“益”或“害”是不科学的，不足为据的，同样也不能因为某种蚂蚁有一定的药效就说她对人类有益，应该具体分析。 我们经常在户外见到的小黑蚂蚁，也是我们所处的生物链中较重要一环，我们丢弃的食物垃圾、碎渣、死去的昆虫尸体等等，如果没有蚂蚁等昆虫的进一步消化，我们所生活的环境很快就会变得腐臭不堪。
