| The life-history and biology of Dirphia araucariae Jones, 1908, including its life fertility table, are here described. Moths were reared in the laboratory under controlled conditions on their host plant, Araucaria angustifolia (Bertoloni) O. Kuntze - Araucariaceae. We describe several life-history traits of the species, namely: developmental period, survival rate, growth rate, fertility, fecundity, sex ratio, cephalic capsule width, and pupal weight. Mean duration of life stages were: egg = 26.78 days; larva = 61.78 days; prepupa = 6.85 days; pupa = 62.46 days; adult = 8.37 days. We found statistically significant differences between sexes for adult, larval and pupal stage duration; larval stage was longer in females while pupal stage was longer in males.... |

| This study describes the life cycle of Agrotis malefida Guenée, 1852 (Noctuidae: Noctuinae) under laboratory conditions. The insects were reared in a controlled environment (25 ± 1ºC, 70 ± 10% RH and 14 hours photo phase) and observed daily. The larvae were fed Greene's artificial diet and adults were offered a 10% sucrose solution. The viability and duration of immature stages were assessed. The experiment initiated with 2,410 eggs. Larvae were isolated shortly after hatching. Longevity, pre-, post- and oviposition, fecundity and fertility of 13 adult couples were also evaluated. The viability of eggs, larvae, pupae and pre-pupae was 96.72, 91.25, 78.37 and 95.26%, respectively. The average duration of egg, larva, pre-pupa, pupa and adult was 7.93, 54.26,... |

| The goal of this work was to describe aspects of the biology and morphology of Leucanella viridescens (Walker, 1855), a polyphytophagous species that is a pest to several crops of economical interest and whose larvae may cause erucism. Biological parameters were obtained under controlled conditions: temperature of 25 ± 1ºC, relative humidity of 70 ± 10%, and a 14 h photophase. Morphological and behavioral aspects were analyzed in each developmental phase. The larval stage had six instars, with an average growth rate of 1.396. A high degree of polyphytophagy was observed, including over 49 host plant species belonging to 25 families, especially Leguminosae, Solanaceae and Salicaceae. The considerable chromatic variability of the adults obtained from the... |
