目前，紅火蟻已傳播至我國12個(gè)省份，435個(gè)縣市區(qū)，尤其是近5年來新增紅火蟻發(fā)生縣級(jí)行政區(qū)191個(gè)，較2016年增長了一倍。紅火蟻是全球公認(rèn)的百種最具危險(xiǎn)的入侵物種之一，攻擊性強(qiáng)和叮咬毒性大是它的主要特點(diǎn)。

At present, RIFA has spread to 12 provinces, 435 counties and municipalities in my country, especially 191 county-level administrative districts with newly-increased RIFA occurrences in the past 5 years, which has doubled compared with 2016. The red fire ant is recognized as one of the hundred most dangerous invasive species in the world. Its main characteristics are its aggressiveness and biting toxicity.

據(jù)悉，紅火蟻對(duì)人的殺傷力源自它的攻擊性和反復(fù)蜇刺的能力。紅火蟻四肢有力，可支撐高于體重?cái)?shù)倍的重量，當(dāng)上顎鉗住人的皮膚后，單手很難將其甩掉，紅火蟻趁機(jī)用腹尾的螯針連續(xù)發(fā)起進(jìn)攻。每次叮刺腹部時(shí)，毒囊釋放出毒液。

It is reported that the red fire ant's lethality to humans comes from its aggressiveness and ability to sting repeatedly. The RIFA has powerful limbs and can support a weight several times higher than its body weight. When the upper jaw clamps on the human skin, it is difficult to shake it off with one hand. The RIFA took the opportunity to continuously attack with the pincers on the belly tail. Each time it stabbed the abdomen, the venom sac released venom.

央視報(bào)道稱，紅火蟻攻擊性強(qiáng)，不少居民家中的豬、雞鴨、狗等都會(huì)被咬，人在野外活動(dòng)也容易被紅火蟻咬到，除了瘙癢疼痛之外，有些人還會(huì)過敏，建議馬上去看醫(yī)生，大家要注意。

CCTV reported that red fire ants are highly aggressive. Many residents’ pigs, chickens, ducks, and dogs will be bitten. People are also prone to be bitten by red fire ants in outdoor activities. In addition to itching and pain, some people are also allergic. It is recommended to see a doctor immediately, everyone should pay attention.

相關(guān)專家表示，紅火蟻的入侵的區(qū)域在持續(xù)擴(kuò)大，不斷地向更北、更西的地區(qū)擴(kuò)張，目前已經(jīng)入侵到浙江的杭州、湖北孝感、重慶渝中、四川廣元等一線，最北已接近秦嶺地區(qū)了。關(guān)于紅火蟻對(duì)農(nóng)林業(yè)生產(chǎn)的影響主要體現(xiàn)在三個(gè)方面，第一個(gè)，直接地取食作物的根、莖、葉、果實(shí)、地下部分等等造成危害，比如說直接取食導(dǎo)致甘薯產(chǎn)量降低30%；第二個(gè)，入侵各種農(nóng)業(yè)區(qū)域以后，導(dǎo)致下地干活的農(nóng)民操作很不方便，受傷害的幾率相當(dāng)高，所以導(dǎo)致一些丟荒；第三個(gè)，紅火蟻發(fā)生以后，導(dǎo)致一些病蟲害發(fā)生比以前嚴(yán)重多了，比紅火蟻沒有發(fā)生區(qū)嚴(yán)重了可能50%-80%。

Relevant experts said that the area where the red imported fire ants invaded is continuing to expand, expanding further to the north and west. It has now invaded Hangzhou in Zhejiang, Xiaogan in Hubei, Yuzhong in Chongqing, and Guangyuan in Sichuan. The northernmost area is close to the Qinling Mountains. Area. Regarding the impact of RIFA on agricultural and forestry production, it is mainly reflected in three aspects. The first is to directly feed on the roots, stems, leaves, fruits, and underground parts of crops to cause harm. For example, direct feeding leads to a decrease in sweet potato production. 30%; second, after invading various agricultural areas, it is very inconvenient for farmers to work in the land, and the probability of being injured is quite high, which leads to some wasteland; third, after the occurrence of red fire ants, it causes some pests and diseases The occurrence is much more serious than before, and it may be 50%-80% more serious than the area where the RIFA did not occur.

農(nóng)業(yè)農(nóng)村部種植業(yè)管理司有關(guān)負(fù)責(zé)人表示，針對(duì)近年來紅火蟻在部分省份加快傳播蔓延的形勢(shì)，要強(qiáng)化部門協(xié)作，加強(qiáng)檢疫監(jiān)管和監(jiān)測調(diào)查，抓住春秋兩季紅火蟻活躍期組織開展集中防控，為糧食連年增產(chǎn)和種植業(yè)持續(xù)穩(wěn)定發(fā)展提供重要保障。

The relevant person in charge of the Planting Management Department of the Ministry of Agriculture and Rural Affairs stated that in response to the accelerated spread of RIFA in some provinces in recent years, it is necessary to strengthen departmental collaboration, strengthen quarantine supervision and monitoring and investigation, and organize the concentration of RIFA during the active period of spring and autumn. Prevention and control provide an important guarantee for the continuous increase in grain production and the sustained and stable development of the planting industry.
