Description
Summary:The objective of this research was to describe the biological and morphometric aspects of the parica tree defoliator, Syssphinx molina (Cramer), and make recommendations about the insect rearing. The life cycle was 62.9 days with mean periods for the egg, larval, pre-pupal and pupal stages of 5.6, 31.1, 2.2 and 16.6 days respectively. The pupal viability was 60.5% for females and 48.6% for males. The sexual ratio was 0.5 with mean production of 182.3 ± 2.2 eggs per female and egg viability of 24.3%. The mean longevity was 7.9 ± 2 and 8.1 ± 3 days for females and males respectively. Other parameters were also observed and compared with description of other Saturniidae species.O objetivo desse trabalho foi descrever os aspectos biológicos e morfométricos da lagarta desfolhadora do paricá, Syssphinx molina (Cramer), e fazer recomendações para a criação do inseto. O ciclo de vida foi de 62,9 dias com períodos médios para as fases de ovo, lagarta, pré-pupa e pupa de 5,6; 31,1; 2,2 e 16,6 dias, respectivamente. A viabilidade das pupas foi de 60,5% para fêmeas e 48,6% nos machos. A razão sexual foi de 0,5 e a produção média de 182,3 ± 2,2 ovos por fêmea com viabilidade de ovos de 24,3%. A longevidade média foi de 7,9 ± 2 e 8,1 ± 3 dias para fêmeas e machos, respectivamente. Outros parâmetros foram igualmente observados e comparados com a descrição de outras espécies de Saturniidae.
