Resumo: The Psyllidae are sap-suckers insects, highly host and food specific, found mainly in sprouts, and are considered important guava pests. Large populations of these insects can be hazardous, since they cause plant weakness by the toxic action of the saliva injected during their feeding process. The objective of this work was to verify the population fluctuation of the psyllidae Trizoida limbata in guava trees in Londrina, Paraná, Brazil. The monitoring of an adult T.limbata population was carried out in areas of wild guava trees, using 10 yellow adhesive traps, 30 m far from each other. Collection took place monthly from March 2002 to May 2003. T.limbata populations were found during every month of the year, reaching their peak in October. Average and maximum temperatures showed a significant correlation with the psyllidae population fluctuation, affecting it positively. Heavy rain periods and low temperatures were not restricting, but they caused a reduction in population

Altas populações podem tornar-se nocivas, pois provocam depauperamento das plantas pela ação tóxica da saliva injetada durante sua alimentação. O objetivo deste trabalho foi conhecer a flutuação populacional do psilídeo Triozoida limbata em goiabeiras na região de Londrina, Paraná. Em áreas de ocorrência natural de plantas de goiaba foi realizado o monitoramento da população de adultos utilizando-se 10 armadilhas adesivas amarelas, colocadas uma por planta, distanciadas cerca de 30 metros entre si. As coletas foram realizadas mensalmente de março de 2002 a maio de 2003. Populações de T. limbata ocorreram durante todos os meses do ano, com pico em outubro. Temperaturas médias e máximas apresentaram correlação significativa com a população do psilídeos, afetando-a positivamente. Períodos com alta pluviosidade ou baixas temperaturas não foram limitantes, mas causaram redução na população.UEL2004-05-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/221910.5433/1679-0359.2004v25n2p87Semina: Ciências Agrárias; Vol. 25 No. 2 (2004); 87-92Semina: Ciências Agrárias; v. 25 n. 2 (2004); 87-921679-03591676-546Xreponame:Semina.
