Abstract

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is a polyphagous agricultural pest recorded in Europe, Asia, Africa, Oceania, and recently South America. Larvae of H. armigera are recorded from over 67 host families, including Asteraceae, Fabaceae, Malvaceae, Poaceae, and Solanaceae. This study documents for the first time H. armigera larvae feeding on inflorescences of “boldo-rasteiro” Plectranthus neochilus Schltr. (Lamiales: Lamiaceae). The species was identified according to external and internal characteristics of adults, morphology of eggs, and by molecular characterization.

 

Sumário

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) é uma praga agrícola polífaga com distribuição geográfica registrada na Europa, Ásia, África, Oceania e, recentemente, na América do Sul. Devido à sua distribuição mundial, suas larvas foram relatados em cerca de 67 famílias, incluindo Asteraceae, Fabaceae, Malvaceae, Poaceae e Solanaceae. Com o recente registro de sua ocorrência no Brasil, novas espécies de plantas hospedeiras tem sido registradas. Portanto, este estudo relata a primeira ocorrência de lagartas de H. armigera atacando inflorescências de “boldo-rasteiro” Plectranthus neochilus Schltr. (Lamiales: Lamiaceae). A espécie foi identificada de acordo com as características externas e internas, morfologia dos ovos e também por caracterização molecular.
