ALGUNS ARTRÓPODES VENENOSOS
ARTRÓPODES – ARANHAS
Aranha armadeira: as aranhas armadeiras possuem esse nome porque quando ameaçadas assumem uma postura ameaçadora, apoiando-se com as patas traseiras e mantendo as duas dianteiras levantadas, numa posição de bote. Pode ser encontrada em lugares escuros, cachos de bananas, sapatos, vegetação, etc. Pode ser reconhecida pela sua cor cinza ou castanho escuro, corpo e pernas com pêlos curtos, perto dos ferrões os pêlos são vermelhos e atingem até 17cm de comprimento quando adultas (incluindo as pernas). Aranha marrom: atingem cerca de 3 a 4 cm, com cor amarelada. É uma aranha que vive em teias irregulares (parecidas com um lençol de algodão) construídas em tijolos, telhas, barrancos, cantos de parede, etc. Os acidentes são raros, porém geralmente são graves, com formação de ferida no local da picada e sensação de queimadura.
Aranha de grama: possuem cor acizentada ou marrom, com pêlos vermelhos perto dos ferrões e uma mancha escura em forma de flecha sobre o corpo. Vive em gramados e residências. São freqüentes os acidentes mas não são graves.
Aranha caranguejeira: São aranhas grandes (podendo chegar a 9cm só de corpo). São vários os gêneros, porém o mais perigoso no Brasil é o do Trechona, que ocorre desde o norte até o sul do país. As aranhas desse gênero possuem um veneno neurotóxico, porém sem risco de morte para o acidentado, não necessitando a aplicação de soro.
Aranha viúva-negra: são aranhas pretas com manchas vermelhas no abdômem. As fêmeas têm de 2,5 a 3 cm e os machos podem ser de 3 a 4 vezes maior. Vivem em teias construídas em vegetações rasteiras, arbustos, barrancos, etc. Para as espécies brasileiras de viúva negra, não são produzidos soros pois os acidentes são raros e geralmente são de média ou pouca gravidade.
ARTRÓPODES - LACRAIAS
As lacraias podem ser encontradas em qualquer lugar. Possui ferrões na parte debaixo da cabeça, e não nos últimos segmentos (muitos acham que o ferrão está na parte de trás do corpo porque a lacraia levanta o mesmo quando ameaçada). Os acidentes são raros e geralmente de baixa gravidade, não sendo necessário a produção de soro.
ARTRÓPODES - INSETOS
Lonomia obliqua: Esta taturana tem o corpo coberto por pêlos espinhosos que soltam um veneno poderoso. A substância inibe a coagulação do sangue das vítimas e causa hemorragias que podem levar à morte. O bicho é comum no Brasil, principalmente nas regiões Sul e Sudeste.Apis mellifera: As populares abelhas parecem inofensivas, mas são perigosas porque, além de irritadiças, costumam atacar em bando. Quando alguém recebe várias picadas, o excesso de veneno pode causar insuficiência renal e anemia aguda. Quanto mais ferroadas, maior o risco de morte.
ARTRÓPODES - ESCORPIÕES
Escorpião amarelo: podem ser encontrados desde a margem direita do rio São Francisco até a fronteira Paraná – Santa Catarina. É muito comum em Minas Gerais (especialmente em Belo Horizonte). No Estado de São Paulo, poderá ser encontrada na região do Vale do Paraíba, Rio Preto e vizinhanças e em focos isolados na Capital. É um escorpião que poderá ser encontrada facilmente em ambientes urbanos.Escorpião marrom: é um escorpião muito comum, sendo encontrado nos mesmos locais do escorpião amarelo, além de ser encontrado também em algumas regiões de Mato Grosso e de Santa Catarina. É o mais comum em São Paulo. Pode ser encontrado nas regiões do Morumbi, Pacaembu e ao longo do Rio Pinheiros. É encontrado em campos e matas ralas, procurando refúgios em cupinzeiros, debaixo de pedras, fendas de barrancos, etc.
Hábitos dos escorpiões: são animais que caçam a noite. Durante o dia, procuram esconderijos, como por exemplo tronco de árvores, frestas nas paredes, sapatos, toalhas, etc. Não são considerados animais violentos.
Efeitos do veneno no homem
O veneno dos escorpiões é neurotóxico, obedecendo aos seguintes critérios de gravidade: casos benignos (apenas dor moderada); casos médios (dor intensa no local e sudorese); casos graves (dor muito intensa, hipotermia, sudorese, aumento da pressão sangüínea, náuseas e vômitos).
CONTROLE E PREVENÇÃO DOS ARTRÓPODES VENENOSOS
* Manter limpos quintais, jardins e terrenos baldios, não acumulando entulho e lixo doméstico.
* Aparar a grama e recolher as folhas caídas.
* Vedar soleiras de portas com saquinhos de areia ou frisos de borracha. Colocar telas nas janelas, vedar ralos de pia, tanque e de chão.
* Colocar o lixo em sacos plásticos, que devem ser mantidos fechados.
* Examinar roupas, calçados e toalhas antes de usá-los.
* Andar sempre calçado.
* Usar luva de raspa de couro ao trabalhar com materiais de construção.
* Inseticida NÃO resolve o problema.
