ABSTRACT
Insect galls of restinga areas of Ilha da Marambaia, Rio de Janeiro, Brazil. This study carried out an insect gall inventory in restinga areas of Ilha da Marambaia, in the municipality of Mangaratiba, Rio de Janeiro, Brazil. Sampling was carried out monthly from April 2010 to March 2011 along the full extension of seven beaches. A total number of 147 gall morphotypes associated with 70 plant species were found, distributed in 33 plant families, and at least 54 genera. Myrtaceae was the botanical family with the highest richness of gall morphotypes and host species, followed by Bignoniaceae, Fabaceae, Asteraceae, Euphorbiaceae, Sapindaceae, and Malpighiaceae. Most of the gall morphotypes occurred in leaves (78 morphotypes), 38 in stems, 14 in flowers, eight in buds and fruits, and one in adventitious roots. The galling insects belong to the five orders: Diptera, Coleoptera, Hemiptera, Lepidoptera, and Thysanoptera. Cecidomyiidae (Diptera) was the most common galling taxon (78 morphotypes), represented by 87 species, being 78 gallers, seven inquilines and two predators. In addition to the gallers, parasitoids, inquilines, and predators were also found.
ABSTRACT
Foi estudada a biologia e preferência alimentar do curuquerê-da-couve, Ascia monuste orseis (Latreille) na planta invasora R. raphanistrum L. Ovos de A. monuste orseis foram coletados nas plantas de couve manteiga da fazenda da Universidade Estadual de Londrina (UEL), PR. As lagartas foram individualizadas, recebendo folhas de nabiça diariamente, observando-se os ínstares e registrando-se a mortalidade. A duração média da fase larval foi de 12,9 (± 0,08) dias, com mortalidade de 42,0 por cento; a duração média da fase pupal foi 6,7 (±0,13) dias e a mortalidade de 38,4 por cento. O curuquerê preferiu alimentar-se de nabiça, comparativamente com a couve manteiga, Brassica oleracea var. acephala.
The biology and feeding preference of the kale leafworm, Ascia monuste orseis (Latreille) on the weed Raphanus raphanistrum Godart was studied. Eggs were collected on plants at the farm of the Universidade Estadual de Londrina (UEL), PR, Brazil. Neonate caterpillars were individualized and were daily fed on leaves of R. raphanistrum; instar duration and mortality were recorded. Mean duration of the larval stage was 12.9 (± 0.08) days and mortality was 42.0 percent. Mean duration of the pupal stage was 6.7 (± 0.13) days, and mortality was 38.4 percent. A. monuste orseis prefered feeding on leaves of R. raphanistrum, than leaves of kale Brassica oleracea var. acephala.
