Percepção química e visual de Anastrepha fraterculus (Diptera, Tephritidae) em laboratório

A mosca-das-frutas-sul-americana, Anastrepha fraterculus (Wiedemann, 1830), é uma das principais pragas da fruticultura no Brasil. Durante a alimentação, as larvas fazem galerias nos frutos, alterando o sabor e prejudicando a produção e comercialização dos mesmos. O presente trabalho teve como objetivo estudar fatores envolvidos na escolha do hospedeiro por A. fraterculus. Foram avaliadas as respostas eletroantenográficas de machos e fêmeas a extratos etanólicos de frutos verdes e maduros de pessegueiro - Prunus persica, cultivar Chimarrita (Rosaceae), pitangueira - Eugenia uniflora (Myrtaceae), guabirobeira - Campomanesia xanthocarpa (Myrtaceae) e araçazeiro - Psidium cattleianum (Myrtaceae). Foram também observadas as influências da cor (amarela, verde e vermelha) e da composição do substrato de oviposição (polpas de araçá, guabiroba, pitanga e pêssego) na fecundidade da espécie. As respostas eletroantenográficas de fêmeas foram significativamente distintas para os extratos de guabiroba verde e madura, araçá maduro e pitanga verde. Em antenas de machos, as maiores despolarizações médias foram registradas em resposta aos extratos de guabiroba verde e madura, araçá verde e maduro e pitanga verde. As respostas eletrofisiológicas geradas não diferiram estatisticamente entre os sexos, para todos os tratamentos. A cor do substrato não afetou a oviposição. As fêmeas ovipositaram mais nos substratos contendo polpa de pêssego e de guabiroba, quando comparados aos respectivos controles.

Single period Markowitz portfolio selection, performance gauging and duality: a variation on Luenberger's shortage function

Markowitz portfolio theory (1952) has induced research into the efficiency of portfolio management. This paper studies existing nonparametric efficiency measurement approaches for single period portfolio selection from a theoretical perspective and generalises currently used efficiency measures into the full mean-variance space. Therefore, we introduce the efficiency improvement possibility function (a variation on the shortage function), study its axiomatic properties in the context of Markowitz efficient frontier, and establish a link to the indirect mean-variance utility function. This framework allows distinguishing between portfolio efficiency and allocative efficiency. Furthermore, it permits retrieving information about the revealed risk aversion of investors. The efficiency improvement possibility function thus provides a more general framework for gauging the efficiency of portfolio management using nonparametric frontier envelopment methods based on quadratic optimisation.
