Biology and thermal requirements of Utetheisa ornatrix (L.) (Lepidoptera: Arctiidae) reared on artificial diet

Abstract: 18, 20, 22, 25, 28, 30, and 32ºC 70±20% RH, . Lower threshold temperatures (TT) and thermal constants (K) for the egg, larval and pupal stages were 12.7ºC and 51.2 GDD, 13.5ºC and 290.9 GDD, 13.8ºC and 108.4 GDD, respectively; TT and K values for the biological cycle were 13.8ºC and 436.3 GDD.

“…To illustrate these developments, we will analyze the occurrence data for the tiger moth Utetheisa ornatrix (Linnaeus, 1758) (Lepidoptera, Arctiidae). The larvae of this Neotropical moth feed mainly on non-ripened pods and developing seeds of Fabaceae shrubs of the genus Crotalaria (Ferro et al 2006;Signoretti et al 2008). The larvae sequestrate pyrrolizidine alkaloids from their host plants and use them as a defense mechanism and the precursors of sexual pheromones.…”

“…A longevidade de machos e fêmeas foi de 21,9±7,9 e 21,8±6,1 dias, respectivamente, e a razão sexual foi 0,5±0,1. Os dados de longevidade e fecundidade de H. indecisa foram próximos aos de outras espécies de Arctiidae, como Halysidota caryae Harris (Lawrence, 1992), Amsacta moorei Butler (Saini, 1993) e Utetheisa ornatrix (L.) (Signoretti et al, 2008). Tais diferenças podem ser atribuídas à dieta utilizada no desenvolvimento da fase larval e à própria espécie, uma vez que essas variáveis biológicas são características de cada organismo.…”

“…Pelo menos 21 espécies associadas ao milho (Zea mays L.) são conhecidas, distribuídas nas famílias Cosmopterigidae, Crambidae, Noctuidae, Pyralidae, Saturnidae e Arctiidae, e esta última é representada pela espécie Hypercompe indecisa (Walker, 1855) (Silva et al, 1968;Sanchez Soto & Nakano, 2003).…”
