Tabelas de Vida de Fertilidade de Brevicoryne brassicae (L.) (Hemiptera: Aphididae) em Condições de Campo

Abstract: -Studies related with life tables are fundamental for the understanding of the population dynamics of insects. In this work, Brevicoryne brassicae (L.) was studied during spring, summer, fall and winter through age-specific life tables aiming to evaluate the influence of temperature on its population dynamic. The experiments were carried out observing B. brassicae enclosed in leaf cages fixed in kale, Brassica oleracea L. var. acephala DC. The age-specific life table parameters, computed on a degree-day time s… Show more

“…Increases in temperature favor B. tabaci and T. tabaci populations while heavy rain and high humidity are deleterious to these insects (Horowitz, 1986;Lorini & Dezordi, 1990;Horowitz et al, 1994;Gonçalves, 1997;Leite et al, 2002a). On the other hand, high temperatures and rainfall are important mortality factors of aphids in field (Nakata, 1995;Cividanes, 2002;Cividanes & Santos, 2003).…”

“…Com base em dados de Cividanes (2002b), determinou-se a regressão linear entre a taxa de mortalidade diária de B. brassicae, em plantas de couve, e a média das temperaturas mínimas dos sete dias anteriores ao dia da constatação da mortalidade, entre 8 e 23 de maio de 1999. (Figuras 2 e 3).…”

“…La construcción de tablas de vida y fertilidad permiten comprender la dinámica poblacional, las tasas de supervivencia y reproducción (Carey, 1993;Cividanes, 2002), así como estudiar aspectos de la biología de una especie, tales como tiempo de desarrollo y fecundidad (Kazak et al, 2002). Las tablas de vida representan de manera sintética y numérica las principales características concernientes a la población en estudio (Rabinovich, 1978) y constituyen una herramienta básica para elaborar estrategias de control (Southwood & Henderson, 2000) permitiendo estudiar el impacto de los enemigos naturales sobre una población en programas de control biológico.…”
