Life cycle and reproductive patterns of Triatoma rubrovaria (Blanchard, 1843) (Hemiptera: Reduviidae) under constant and fluctuating conditions of temperature and humidity

The aim of this study was to evaluate the temperature and relative humidity influence in the life cycle, mortality and fecundity patterns of Triatoma rubrovaria. Four cohorts with 60 recently laid eggs each were conformed. The cohorts were divided into two groups. In the controlled conditions group insects were maintained in a dark climatic chamber under constant temperature and humidity, whereas triatomines of the ambiental temperature group were maintained at room temperature. Average incubation time was 15.6 days in the controlled conditions group and 19.1 days in the ambiental temperature. In group controlled conditions the time from egg to adult development lasted 10 months while group ambiental temperature took four months longer. Egg eclosion rate was 99.1% and 98.3% in controlled conditions and ambiental temperature, respectively. Total nymphal mortality in controlled conditions was 52.6% whereas in ambiental temperature was 51.8%. Mean number of eggs/female was 817.6 controlled conditions and 837.1 ambiental temperature. Fluctuating temperature and humidity promoted changes in the life cycle duration and in the reproductive performance of this species, although not in the species mortality.

Owner portraits and heraldry in the "Lamoignon Hours"

Because of the distance in time and the lack of testifying documents, one should be extremely careful when labelling portraits in medieval books of hours as donor portraits or owner portraits. There are, however, manuscripts that reveal their first owner within their decorative programme, and the Lamoignon Hours (Lisbon, Gulbenkian, ms LA 237) is one of these. This article aims to discuss the iconography of the three portraits found on f.165v, f.202v and f.286v, as well as the relevance of portraiture and heraldic insignia in books of hours and the significance of such content to the original owner and to those who possessed the book afterwards.

Combate ao ácaro rajado Tetranychus urticae Koch, 1836 e ao bicudo do algodão Anthonomus grandis grandis Boheman, 1843

Este trabalho tem o objetivo de dar continuidade às pesquisas que visam o combate ao ácaro rajado do algodoeiro Tetranychus urticae. Koch, 1836. Para tal objetivo, em oito tratamentos foram utilizados seis produtos:fempropatrina(300 g/ha), binapacril (400g/ha) , flubenzimina (600g/ha) , carbamato UC 81341 (150 g IA/ha), clofentezina em dois tratamentos (150 g/ha repetidas em três aplicações e 375 g/ha) e bifentrina (70g/ha). A conclusão, extraída da análise dos resultados, permite verificar que os seguintes tratamentos agiram consideravel mente sobre a população do àcaro: ciofentezina em três aplicações e bifentrina. No final do ensaio, procedeu-se à avaliação dos danos ocasionados pelo bicudo do algodoeiro Anthonomus grandis grandis às maçãs. A infestação foi semelhante em todos os tratamentos.
