| 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... |

| The goal of this contribution was to study the biology and morphology of all developmental stages of Molippa cruenta (Walker, 1855), a member of Hemileucinae (Saturniidae), endemic to southern Brazil and northeastern Argentina. Daily observations were carried out on individuals reared under controlled temperature (25 ± 1ºC), relative humidity (70 ± 10%) and photophase (14 hours of light). The duration and viability of each developmental phase, as well as morphological and behavioral aspects of each stage, were evaluated. Under laboratory conditions, the life-cycle of M. cruenta was completed in 150 days, with mean periods for egg, larva, pupa and adult phases being 35, 71.95, 37.85, 19.17 and 4.81 days, respectively. The larval phase included six instars,... |
