Identificação de plantas hospedeiras da broca do abacate, Stenoma catenifer Walsingham (Lepidoptera: Elachistidae) no Rio Grande do Sul

Abstract

Identifi cation of Host Plants of the Avocado Borer, Stenoma catenifer Walsingham (Lepidoptera: Elachistidae) in Rio Grande do Sul ABSTRACT-Fruits of Nectandra megapotamica Mez and Cinnamomum camphora (L.) (Lauraceae) were collected in Rio Grande do Sul, Brazil, in 2004. Species of fi ve families of insects were found inside the fruits: two fl y species (Diptera: Drosophilidae: Drosophila spp.), six beetle species, Heilipus sp., Conotrachelus sp. (Curculionidae), Hypothenemus sp. (Scolytidae) and three species of Carpophilus (Nitidulidae), and moths (Lepidoptera: Elachistidae). The moth especimes were identifi ed as Stenoma catenifer Walsingham, the avocado borer. The occurrence of the moth was predominant from early April until middle May. The natural larval infestation level was low. Two new host plant of the pest were identifi ed.

New Record of Stenoma Catenifer1 at Hueytamalco, Puebla, Mexico

“…Larvae feed on the pulp and seed, inducing premature fruit drop and causing as much as 80% crop loss (Nava et al 2005). S. catenifer causes damage from Mexico to South America (Hoddle and Parra 2013) to plants of the Lauraceae family (Cervantes-Peredo et al 1999), including P. americana (avocado) and Persea schiedeana Nees (chinina) (Link and Link 2018). Both avocado species are of economic and regional importance.…”
