Fruits of Nectandra megapotamica Mez and Cinnamomum camphora (L.) (Lauraceae) were collected in Rio Grande do Sul, Brazil, in 2004. Species of five families of insects were found inside the fruits: two fly 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 identified 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 identified.
2004年，在巴西南里奥格兰德州采集了大果楠（Nectandra megapotamica Mez）和樟树（Cinnamomum camphora (L.)）（樟科）的果实。在果实内发现了五个昆虫科的物种：两种蝇类（双翅目：果蝇科：果蝇属）、六种甲虫、Heilipus属、Conotrachelus属（象甲科）、Hypothenemus属（小蠹科）以及三种Carpophilus属（露尾甲科），还有蛾类（鳞翅目：细蛾科）。蛾类标本被鉴定为鳄梨蛀果蛾（Stenoma catenifer Walsingham）。该蛾类的出现从4月初到5月中旬占主导。自然幼虫侵染水平较低。确定了该害虫的两种新寄主植物。
