First global record of Podisus nigrispinus (Hemiptera: Pentatomidae) as predator of Gonipterus platensis (Coleoptera: Curculionidae) larvae and adults
Keywords:
Eucalyptus, biological control, integrated management, Brazil,Abstract
Summary
Native to Australia Gonipterus platensis Marelli (Coleoptera: Curculionidae) is the main beetle defoliator of eucalyptus worldwide, causing damage in various regions in which it was introduced, where its management relies mostly on biological control with the parasitoid Anaphes nitens (Girault) (Hymenoptera: Mymaridae). In this report, we present the first laboratory evidence of efficient predation by Podisus nigrispinus Dallas (Hemiptera: Pentatomidae) on G. platensis larvae. This predatory species is native to Brazil and a promising biological control agent for use in the integrated pest management of G. platensis.
Sumário
Nativo da Austrália Gonipterus platensis Marelli (Coleoptera: Curculionidae) é o principal besouro desfolhador do eucalipto no mundo, causando danos em diferentes regiões em que foi introduzido, locais onde seu manejo integrado é predominantemente biológicamente com o parastióide de ovos Anaphes nitens (Girault) (Hymenoptera: Mymaridae). No presente trabalho apresentamos a primeira evidência de campo e estimative da eficiência laboratorial do predador Podisus nigrispinus Dallas (Hemiptera: Pentatomidae) predando larvas de G. platensis. Este predador é nativo do Brasil e promissor para ser usando no controle biológico da praga dentro do manejo integrado de G. platensis.
