Última Description of the larva and pupa of the papaw borer weevil Pseudopiazurus papayanus (Marshall) (Coleoptera, Curculionidae, Piazurini) Rev. Bras. entomol. Sousa,Wesley Oliveira de; Rosado-Neto,Germano H.; Moreira,Marcos A. B.; Zarbin,Paulo H. G.. Larvae, pupae and adults of the piazurine weevil Pseudopiazurus papayanus (Marshall, 1922) are associated with Carica papaya Linnaeus,1753 (Caricaceae). The larval and pupal stages are described and illustrated. The sexual differences in the last abdominal segments of the pupae are also illustrated.

Bras. entomol. Sousa,Wesley Oliveira de; Rosado-Neto,Germano Henrique; Marques,Marinêz Isaac. The plastron theory was tested in adults of Neochetina eichhorniae Warner, 1970, through the analysis of the structure that coats these insects' integument and also through submersion laboratorial experiments. The tegument processes were recognized in three types: agglutinated scales with large perforations, plumose scales of varied sizes and shapes, and hairs. The experiments were carried out on 264 adult individuals which were kept submerged at different time intervals (n = 11) and in two types of treatment, natural non-aerated water and previously boiled water, with four repetitions for each treatment. The tests showed a maximum mortality after 24 hours of immersion in the previously boiled water treatment. The survival of the adults was negative and...

Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0085-56262012000300012 Surface swimming behavior of the curculionid Ochetina uniformis Pascoe (Erirhininae, Stenopelmini) and Ludovix fasciatus (Gyllenhal) (Curculioninae, Erodiscini) Rev. Bras. entomol. Sousa,Wesley Oliveira de; Marques,Marinêz Isaac; Rosado-Neto,Germano Henrique; Adis,Joachim. The swimming behavior exhibited by specimens of L. fasciatus and O. uniformis was analyzed frame-by-frame with video observation recorded with a digital camera, attached to a stereomicroscope. Adults of O. uniformis, an aquatic insect, swim with all three pairs of legs. During the process of swimming the majority of the abdomen and rostrum remain submerged, part of the fore and hind tibiae remain above the surface, while the mid tibiae remain submerged. The mesothoracic legs, during the power-stroke stage, provide the greatest thrust while the metathoracic legs provide the least forward propulsion. The prothoracic legs, extended forward, help to direct the swimming. The semi-aquatic specie L. fasciatus shows the same swimming style as O. uniformis, that...

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0085-56262007000100015 Weevils associated with Pistia stratiotes L. (Araceae) in the Central Amazon Region, with new records for Argentinorhynchus Brèthes (Coleoptera, Curculionidae) Biota Neotropica Sousa,Wesley Oliveira de; Rosado-Neto,Germano Henrique; Marques,Marinêz Isaac; Adis,Joachim. Data on the occurrence of ten weevils species associated with Pistia stratiotes L. (Araceae), from Ilha de Marchantaria, Manaus (Amazonas, Brazil) are presented for the first time. During the period from March to August 2005, 809 weevils specimens were sampled on P. stratiotes, distributed across nine species allocated in five genera of Stenopelmini, in addition to one unidentified species in the Cryptorhynchinae. Among the Stenopelmini, Argentinorhynchus breyeri Brèthes, 1910 (N = 665) was the dominant species, with the highest abundance in July (N = 189) and the lowest in August (N = 11), while Ochetina uniformis Pascoe, 1881 (N = 63), Neochetina bruchi Hustache, 1926 (N = 45), Neohydronomus pulchellus Hustache, 1926 (N = 15), Neohydronomus affinis...
