Aspectos biológicos de Cycloneda sanguínea (Coleóptera: Coccinellidae) alimentadas con pulgones criados en algodón transgénico Bollgard I

Cycloneda sanguinea is an important biological control agent of aphid cotton. The objective of this study was to evaluate the biological aspects of C. sanguinea fed with nymphs and adults of Aphis gossypii reared in DeltaOPAL and NuOPAL cultivars (Bollgard I). The experiment was conducted in the laboratory under controlled temperature (25 +/- 1 degrees C), humidity (70 +/- 10%) and photophase (12 hours). The experimental design was completely randomized, and treatments aphids fed on the two cultivars, and replicates 40 individuals. Each larva was individually until adult emergence of the predator in Petri dishes of 9 cm in diameter with moistened filter paper. For evaluation of individual adults were five couples newly emerged in plastic pots 12 cm in diameter and 9 cm tall, with filter paper for oviposition. The parameters evaluated were: duration and viability of the larval stage, pupal stage duration and survival, adult longevity, reproductive period, post-reproductive and total number of eggs per female. The duration of the larval stage of C. sanguinea was lower when fed aphids reared on the cultivar NuOPAL, while adult longevity and the reproductive period were higher. The female fertility and egg viability were also lower.

Influencia del nivel de inserción ósea del diente soporte en el desplazamiento de PPR de extremidad libre mandibular asociada al implante oseointegrado

The rehabilitation with mandibular distal extension removable partial dentures (DERPD) is complex and the use of implants has been improving the functioning of this approach. The insertion bony level around of the last support tooth is an aggravating factor, since it can harm the longevity of the treatment. Thus, the aim of this research was to evaluate the displacement tendency of a mandibular DERPD associated to an implant, with different insertion bony levels and different connections between the RPD and the support tooth, by finite element analysis. Eight models were made: MA - DERPD, incisal rest, no bony loss; MB - DERPD, distal plate, no bony loss; MC - DERPD, incisal rest, no bony loss, with implant and ERA system; MD - DERPD, distal plate, no bony loss, with implant and ERA system; ME - DERPD, incisal rest, bony loss; MF - DERPD, distal plate, bony loss; MG - DERPD, incisal rest, bony loss, with implant and ERA system; MH - DERPD, distal plate, bony loss, with implant and ERA system. Loads of 50 N in each peak were applied. Displacement maps were obtained and showed that implant favors this association and the bony loss harms the prognostic of the prosthesis. It is concluded that: the introduction of the implant with ERA system reduced the displacement tendency of the tooth and supporting structures; introduction of distal plate reduced the movement tendency of the support tooth; the decrease of the periodontal support didn't influence significantly the displacement tendency of the models with distal plate distal, but it influenced the models with distal incisal rest.
