Record of tritrophic relationship between Syagrus coronata (Martius) Beccari (Arecaceae), Pachymerus nucleorum Fabricius (Coleoptera: Chrysomelidae: Bruchinae) and Heterospilus sp. (Hymenoptera: Braconidae) in the State of Alagoas, northeastern Brazil

Some conservation units in Brazil border urban areas, like the Catolé and Fernão Velho Environmental Protection Area (EPA) State of Alagoas.

Females usually lay eggs on surface fallen fruits immatures feed seed under drupe endocarp; larvae, even protected by hard could be preyed skilled parasitoid wasps. Here, record tritrophic relationship between S. coronata, P. nucleorum, wasp genus Heterospilus (Hymenoptera: Braconidae) an urbanized region Alagoas, to remnant EPA communicated. Fruits were collected soil canopy Licuri palms “Universidade Federal de Alagoas” A. C. Simões Campus transported laboratory monitoring. Either adults wasps beetles recorded. The specimens had seeds upon Forest. involving seems indicate tenacity natural biological control.
