Eficácia de diferentes insecticidas no combate à Cryptotermes brevis

Abstract

Foram realizados testes laboratoriais e alguns testes em estruturas com seis insecticidas contra a térmita de madeira seca Cryptotermes brevis. Os seis produtos utilizados foram o XILOFENE, TERMINATE, TERMIDOR, XT-2000, WOCOSEN e BOROWOOD. Várias experiências em laboratório foram realizadas com o objectivo de comparar os produtos, usando diferentes critérios. Os testes de contacto e vapor foram realizados com térmitas colocadas em papel de filtro em caixas de Petri. Os testes de difusão e repelência foram efectuados em blocos de madeira tratados. Os critérios designados por “escapabilidade” e “afastamento” foram efectuados num bloco de madeira com cinco câmaras. Todos os produtos, com excepção do BOROWOOD, mataram 100% das térmitas em 24 h., no teste de contacto. No teste de vapor, o XT-2000 provocou a mortalidade mais elevada. No teste de difusão, o TERMIDOR provocou a mortalidade mais elevada. No teste de repelência, o TERMINATE e o XILOFENE produziram elevada mortalidade, mesmo nas térmitas libertadas no extremo do bloco não tratado. No teste do bloco de madeira com cinco câmaras, no extremo tratado, todos os produtos, com excepção do BOROWOOD, mataram 100% das térmitas em 24 h., pelo que as térmitas não “escapam” a nenhum dos produtos, i.e., “não escapável”. No entanto, os produtos variaram bastante em termos do efeito “afastamento”, medido com base na mortalidade retardada das térmitas colocadas no extremo não tratado. O XT-2000 estabeleceu uma elevada repelência, tendo as térmitas evitado aproximar-se. Em contraste, o TERMIDOR, o XILOFENE, o TERMINATE e o WOCOSEN exibiram uma menor repelência e, consequentemente, as térmitas aproximaram-se mais, havendo uma mortalidade retardada das térmitas na extremidade não tratada. O XILOFENE foi o produto menos repelente e foi aquele que induziu a mortalidade mais elevada nas térmitas localizadas no extremo não tratado. Experiências de campo com o XT-2000 resultaram numa taxa de redução na produção de partículas fecais de cerca de 85% em cerca de oito meses. ABSTRACT: Laboratory tests and some structural trials were conducted on six insecticide products against the West Indies drywood termite, Cryptotermes brevis. The products included Xilofene, Terminate, Termidor, XT-2000, Wocosen, and Borowood. Several different laboratory tests were conducted to compare the products by different criteria. Contact and vapor tests were conducted with termites on filter paper in Petri dishes. Diffusion and repellency tests were conducted on treated wood blocks. Criteria called “escapability” and “avoidability” were tested in a five-chambered wood block. All of the products except Borowood killed 100% of the termites within 24 hours in the contact test. In the vapor test, XT-2000 produced the highest mortality. In the diffusion test, Termidor produced the highest mortality. In the repellency tests, Terminate and Xilofene both induced high mortality even among those termites released on the untreated side of the wood block. In the five chambered tests, complete or nearly complete mortality occurred on the treated side within 24 hours for all products except Borowood, so it appeared that none of the products was escapable. However the products varied markedly in avoidability as reflected by delayed mortality among termites introduced on the untreated side. XT-2000 exhibited high repellency and very high avoidability by termites on the untreated side. In contrast, Termidor, Xilofene, Terminate and Wocosen all exhibited less repellency and therefore less avoidability, eventually leading to a gradual increase in delayed mortality. In both the repellency test and the five chamber test, Xilofene was evidently least repellent and thus least avoidable and induced the highest mortality among termites introduced on the untreated side. Field trials with XT-2000 resulted in a 100% to 82% reduction in pellet production over an eight month post-treatment period.
