“…We did not measure the density of the leaf mines on the trap plants but selected plants with approximately the same number of mines based on a visual estimation of the leaves. In a study examining natural parasitism of leaf‐miners belonging to the genus Calycomyza , the density of leaf mines per plant and per leaf did not affect the rate of parasitism of the leaf‐miner (De Queiroz & Garcia, ). Therefore, we argue that it is unlikely that differences in the trap plants or host density interfered with the host‐locating decisions of the parasitoids in our study.…”

1. In natural ecosystems, plants containing hosts for parasitoids are often embedded within heterogeneous plant communities. These plant communities surrounding host-infested plants may influence the host-finding ability of parasitoids.2. A release-recapture-approach was used to examine whether the diversity and structural complexity of the community surrounding a host-infested plant influences the aggregation behaviour of the leaf-miner parasitoid Dacnusa sibirica Telenga and naturally occurring local leaf-miner parasitoids. Released and locally present parasitoids were collected on potted Jacobaea vulgaris Gaertn.plants infested with the generalist leaf-miner Chromatomyia syngenesiae Hardy. The plants were placed in experimentally established plant communities differing in plant diversity (1-9 species) and habitat complexity (bare ground, mown vegetation, and tall vegetation). Additionally, parasitoids were reared out from host mines on the trap plants.3. Plant diversity did not influence the mean number of recaptured D. sibirica or captures of other locally present parasitoids but the number of recaptured parasitoids was influenced by habitat complexity. No D. sibirica parasitoids were recaptured in the bare ground plots or plots with mown vegetation. The mean number of recaptured D. sibirica generally increased with increasing complexity of the plant community, whereas locally present parasitoids were captured more frequently in communities with more bare ground. There was a unimodal relationship between the number of reared out parasitoids and diversity of the surrounding vegetation with the highest density of emerged parasitoids at intermediate diversity levels.4. The present study adds to the thus far limited body of literature examining the aggregation behaviour of parasitoids in the field and suggests that the preference of parasitoids to aggregate in complex versus simple vegetation is association specific and thus depends on the parasitoid species as well as the identity of the plant community.

“…A larger number of studies correspond to species descriptions and/or deal with economically important organisms (Hespenheide, 1991;Queiroz, 2002;Sinclair and Hughes, 2010). In Brazil, a few studies on the ecology of leaf miners have been published (see D'Araújo and Silva et al,1968;Queiroz, 2002;Queiroz and Garcia, 2009), and a few have dealt with species found at the Restinga biome, for instance Senna appendiculata (Vogel) Wiersema (= S. australis Irwin & Barneby; Leguminosae, Teixeira et al, 1999), Byrsonima sericea DC. (Malpighiaceae, Flinte et al, 2006) and Ouratea cuspidata (A.St.-Hil.)…”

In this study, we describe and present original data on the bionomics and ecology of Tachygonus erythroxyli Hespenheide, New Species, on Erythroxylum subsessile (Mart.). Thirty individuals of E. subsessile were analysed every two months, from October, 2006 to October, 2007 at the National Park of Restinga de Jurubatiba (PNRJ) Carapebus, Rio de Janeiro, Brazil. Females of T. erythroxyli lay their eggs singly on the upper surface of the host's leaves. The mine of T. erythroxyli is expanded with three bubbles, each one representing one larval instar. These mines occur throughout the year in at least half of the host plants and are markedly more abundant in summer. We obtained three parasitoid species, making a total of 53% of the rate of parasitism. Cirrospilus sp. (Eulophidae) was the most prevalent and represented 88% of the parasitoids. The great abundance of Tachygonus mines, their high frequency in their host plant, and local monophagy of this leaf miner weevil suggest a close association between T. erythroxyli and Erythroxylum subsessile.Keywords: Tachygonus erythroxyli, Erythroxylum subsessile, leaf miner, restinga.Mina foliar singular induzida por Tachygonus sp. n. (Coleoptera: Curculionidae: Tachygoninae) em Erythroxylum subsessile (Erythroxylaceae) com descrição da nova espécie ResumoNo presente estudo, foram descritos e apresentados os primeiros dados sobre bionomia e ecologia de Tachygonus erythroxyli Hespenheide, New Species, em Erythroxylum subsessile (Mart.). Trinta indivíduos de E. subsessile foram amostrados a cada dois meses, de outubro de 2006 a outubro de 2007, no Parque Nacional da Restinga de Jurubatiba (PNRJ), Carapebus-Rio de Janeiro, Brasil. Fêmeas de T. erythroxyli colocam ovos isolados na face superior das folhas do seu hospedeiro. A mina de T. erythroxyli é do tipo expandida e apresenta um formato de três bolhas, sendo que cada bolha corresponde a um estádio da larva. Essas minas ocorrem ao longo de todo o ano em pelo menos metade das plantas hospedeiras, sendo marcadamente mais abundantes no verão. Foram obtidas três espécies de parasitoides que, juntas, demonstraram uma taxa de parasitismo de 53%. Cirrospilus sp. (Eulophidae) foi a mais abundante e representou 88% dos parasitoides. A grande abundância de minas de Tachygonus, a alta frequência em seu hospedeiro e a monofagia local desse besouro minador de folhas sugere uma forte associação entre T. erythroxyli e Erythroxylum subsessile.Palavras-chave: Tachygonus erythroxyli, Erythroxylum subsessile, minador foliar, restinga.
