Resumo: In addition to competing with crops, weeds can provide shelter for arthropods in cropping fields and adjacent areas. This study aimed to investigate the occurrence and population fluctuation of insect pests and their natural enemies associated with hairy fleabane (Conyza spp.), in soybean farming areas. The predominant species were Schizaphis graminum, Taylorilygus apicalis, Empoasca spp. and Nysius simulans. Species that comprise important pest complexes, including stink bugs and caterpillars, can develop on fleabane plants. Among them, the stink bugs Edessa meditabunda, Dichelops spp., Piezodorus guildinii, Nezara viridula and Euschistus heros, as well as the caterpillars Anticarsia gemmatalis, Spodoptera frugiperda, Spodoptera eridania, Chrysodeixis includens and Helicoverpa spp. have prevailed. The most common natural enemies were Orius spp., Eriopis connexa, Cycloneda sanuiinea and Chrysoperla spp. The population fluctuation analysis indicated that hairy fleabane mainly hosted stink bugs at the beginning of the crop cycle and after soybean maturation. The caterpillars, however, use this weed as an alternative host throughout the crop cycle, continuing after soybean maturation and harvesting. For natural enemies species, the population fluctuation depends on the occurrence of insects that serve as a food source for them. Thus, it is possible to conclude that hairy fleabane is an important alternative host for pest insects and their natural enemies in soybean crops.

Objetivou-se estudar a ocorrência e flutuação populacional de insetos-praga e inimigos naturais associados a buva (Conyza spp.), em áreas de cultivo de soja. As espécies predominantes foram Schizaphis graminum, Taylorilygus apicalis, Empoasca spp. e Nysius simulans. Espécies que compreendem complexos importantes de pragas, incluindo percevejos e lagartas, são capazes de se desenvolver sobre plantas dessa espécie daninha. Dentre elas, prevaleceram os percevejos Edessa meditabunda, Dichelops spp., Piezodorus guildinii, Nezara viridula e Euschistus heros, e as lagartas Anticarsia gemmatalis, Spodoptera frugiperda, Spodoptera eridania, Chrysodeixis includens e Helicoverpa spp. Os inimigos naturais mais encontrados foram Orius spp., Eriopis connexa, Cycloneda sanuiinea e Chrysoperla spp. A análise de flutuação populacional indicou a ocorrência de percevejos sobre plantas de buva, sobretudo no período inicial do cultivo e após a maturação da soja. Já as lagartas utilizam esta planta como hospedeiro alternativo durante todo o ciclo da cultura, continuando após a maturação e colheita da soja. Para os inimigos naturais, a flutuação das espécies depende da ocorrência de insetos que lhes servem como fonte de alimento. Logo, é possível concluir que a buva é um importante hospedeiro alternativo de insetos-praga e seus inimigos naturais, em cultivo de soja.Escola de Agronomia - Universidade Federal de Goiás2017-10-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/47348Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 3, Jul./Sep. 2017; 336-344Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 3, jul./set. 2017; 336-344Pesquisa Agropecuária Tropical; v. 47, n. 3, jul./set. 2017; 336-3441983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/47348/24360Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessDalazen, GiliardiBigolin, MaurícioValmorbida, IvairStacke, Regis FelipeCagliari, Deise2020-07-13T18:46:46Zoai:ojs.revistas.ufg.br:article/47348Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:17.437838Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
