“…A espécie P. obesulus foi a mais abundante e ocorreu durante todo o período de levantamento. De acordo com Ferreira et al (1997) este inseto é considerado praga severa para o coqueiro anão verde, pois as larvas provocam a queda dos frutos nos primeiros estágios de seu desenvolvimento; entretanto, estudos desenvolvidos em campo e laboratório mostraram que este inseto ataca somente frutos em processo de abortamento, não constituindo praga para o coqueiro (Moura & Vilela, 1998;Moura et al, 2009).…”

O objetivo deste estudo foi determinar as espécies de curculionídeos que ocorrem associadas a um cultivo de coqueiro anão verde, Cocos nucifera L., no município de Linhares, ES. Para a amostragem dos insetos foram utilizadas armadilhas amarelas tipo Moericke. O levantamento foi realizado semanalmente, no período de março/2008 a fevereiro/2009. Foi coletado um total de 952 exemplares pertencentes a 11 espécies: Parisoschoenus obesulus (409 exemplares), Andranthobius bondari (293), Metamasius hemipterus (88), Apion sp. (65), Baris sp. (41), Sibariops sp. (14), Conotrachelus sp. (13), Auletobius sp. (13), Sithopilus zeamais (10), Sibinia sp. (3) e Anthonomus sp. (3). Destas, somente as espécies P. obesulus, A. bondari e M. hemipterus são registradas na literatura associadas ao coqueiro anão verde.

“…Visitors were partly observed and collected during blocks of 30 minutes at different times of the day to obtain a more equilibrated picture of occurrence of insects on this palm during whole days. Additional and complementing observations on this species occurred in the years 1977, 1980, 1983, 1989, 1990, 2007and 2009. For studies of S. petraea in Botucatu in 1980, 1981, 1983, 1985and 1990 flowering individuals were selected and investigated at the same site as for B. paraguayensis.…”

The two cerrado palms Butia paraguayensis and Syagrus petraea were studied with regard to parasitizing and pollinating insects that visit their reproductive organs. At the study site in Botucatu, São Paulo State, both species occurred together, while at the study site in Indianópolis, Minas Gerais state, only S. petraea was growing. Bees of the subfamily Meliponinae and Halictinae were the main pollinators of B. paraguayensis and several beetles and flies were additional pollinators. The visiting beetles divided up in more exclusive parasites, such as the weevils Tripusus leiospathae and Petalochilus lineolatus, and the Colydiidae Bitoma palmarum, which bored and oviposited the closed spathe and whose larvae fed on the flower buds, as well as species of the weevil Microstrates, which bred in staminate flowers. Differently, the curculionids Anchylorhynchus bicolor, Parisoschoenus sp., Dialomia sp., and species of Mystrops (Nitidulididae) behaved as parasites and pollinators. On the other hand, S. petraea shows more evident adaptations for pollination by beetles. This species has Trigona spinipes as prominent bee pollinator, but otherwise beetles dominated as visitors, being them either parasites, pollinators or both. Although several identical beetle genera occur on both palms, at the species level they are different, as for example Anchylorhynchus camposi on S. petraea. At the two distant study sites of S. petraea in Botucatu and Indianópolis, several species, especially of the parasitic insects, are identical, indicating that parasitism is a stronger bond than pollination in this species which is characterized by a generalist pollination mode.
