Resumo: | This work aimed to study the damage, make-decision system, control of Pseudophilothrips sp. (Thysanoptera: Phlaeothripidae) and its relationship with fungic lesions on guava fruits. The thrips Pseudophilothrips sp (Thysanoptera: Phlaeothripidae) and the fungi Collethotricum gloesporiodes and Pestalotia sp were observed on fruits with lesions. The number of lesions/fruit increased in function of the numbers of nymphs and adults of thrips/fruit. The most effective insecticides were carbaryl, cypermethrin, dichlorvos, ethion, fenpropathrin, fenitrothion, fention, lambdacyhalothrin, metamidofos, methyl parathion, permethrin, triclorfon, and vamidothion. The thrips sampling should be done by evaluation of the percentage of young attacked fruit (1.5 to 3 cm of diameter) by nymphs and adults of thrips. The sampling plan should be composed by evaluation of four fruits/plant on nine plants/field. The average of the economic thresholds for red guava cultivars were 0.70% (tractor insecticide application) and 1.82% (conventional knapsack sprayer) of infested guava fruits. The average of economic thresholds for white guava cultivars were 1.15% (tractor insecticide application) and 2.96% (conventional knapsack sprayer) of fruits with Pseudophilothrips sp. |

(Thysanoptera: Phlaeothripidae) e sua relação com lesões fúngicas em frutos de goiaba. O tripes presente nos frutos lesionados foi Pseudophilothrips sp. (Thysanoptera: Phlaeothripidae). Os fungos isolados nas lesões foram Collethotricum gloesporiodes e Pestalotia sp. Verificou-se aumento do número de lesões fúngicas nos frutos em função de maiores densidades do tripes. Os inseticidas mais eficazes no controle do tripes foram: carbaril, cipermetrina, diclorvós, etiom, fempropatrina, fenitrotiom, fentiom, lambdacialotrina, metamidofós, paratiom metílico, permetrina, triclorfom e vamidotiom. A amostragem desse tripes deve ser realizada avaliando-se a percentagem de frutos verdes (diâmetro entre 1,5 a 3 cm) atacados pelo tripes. O plano de amostragem deve ser composto pela avaliação de quatro frutos/planta em nove plantas/talhão. O nível econômico de dano médio para Pseudophilothrips sp. em cultivares com frutos de polpa vermelha é 0,70 (pulverização tratorizada) e 1,82% (pulverização manual) de frutos atacados. Para cultivares com frutos de polpa branca o nível econômico de dano médio é 1,15% (pulverização tratorizada) e 2,96% (pulverização manual) de frutos atacados.Universidade Estadual de Maringá2008-04-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/267510.4025/actasciagron.v25i1.2675Acta Scientiarum.
