“…Their results corroborate our findings that higher humidity levels lengthen the larval period of A. malefida. The occurrence of prepupal diapause in A. malefida (BENTANCOURT & SCATONI 2006) has already been reported for some noctuid species in other genera, such as in Xestia c-nigrum (Linnaeus, 1758) (HONÌK 1979, OKU 1984, Helicoverpa armigera (Hübner, [1809]) (WILSON et al 1979, QURESHI et al 2000, FENG et al 2010, and S. nonagrioides (FANTINOU et al 1996, GADENNE et al 1997, EIZAGUIRRE et al 2008. However, larval and pupal diapause were not expected to occur in A. malefida under the rearing conditions of our experiment (25 ± 1°C, 70 ± 10% RH and 14 hours photoperiod).…”

“…A visible characteristic of arrested development in diapausing pupae was the prolonged presence of pigmented ocelli (Phillips & Newsom 1966). Wilson et al (1979), in Australia, found that time taken to terminate diapause varied considerably between individual pupae.…”

Heliothis armiger confertus (Walker) (Lepidoptera: Noctuidae) was reared on an artificial diet in the laboratory. Larvae and pupae were reared at 25±1°C and 18:6 (LID) photoperiod, and adults were mated at an average of 20°C under natural light conditions. The average generation time was 38 days, with larval period 17.3 days, prepupal period 3.6 days, and pupal period 14.5 days. Other data are: average pupal weight -'( 401.5 mg, o 392.0 mg; average survival to pupa 84.9%; average survival to adult 65.4%; pre-oviposition period 2.7 days; fecundity 973 ± 121 eggs per female; adult lifespan approximately 12 days. The parasitoid Apanteles kazak (Telenga) (Hymenoptera: Braconidae) was reared for several generations using H. a. confertus larvae as hosts. It took, on average, 19.3 days from oviposition to cocoon formation, and 26.8 and 29.0 days for adult male and female emergence respectively. Only 25.9% of the host larvae produced parasite cocoons, and 74.1 % of these produced adult parasitoids. Two Heliothis viruses were produced, with maximum yields for granulosis virus of 40 mg per larva and for nuclear polyhedrosis virus of 11.5 mg per larva.

“…Helicoverpa armigera enters into facultative diapause at the pupal stage (Fitt, 1989). In the field, subtropical populations of the species are capable of overwintering in a state of pupal diapause in Africa and Australia (Roome, 1979;Wilson et al, 1979). In Australia, a HEAPS model has been developed based on the local field information and is being used to predict the number of overwintering pupae of Helicoverpa moths (Dillon, 1998).…”

The timing of diapause induction and overwintering success in the cotton bollworm Helicoverpa armigera were studied outdoors in Chiba (35°N, 140°E) and Kyoto (35°N, 135°E) prefectures, Japan, using local populations collected from Chiba and Mie (34°N, 136°E) Prefectures, respectively. For comparison, a similar experiment was performed in Chiba using a closely related species, H. assulta. Diapause induction in H. armigera was stimulated by low temperatures in autumn, and the incidence of pupal diapause increased sharply with little change in photoperiod. In Kyoto, pupae of H. armigera overwintered successfully in a state of diapause. However, larvae that had hatched from eggs deposited in late autumn suffered high mortality, presumably from the cold; therefore, the pattern of temperature change in autumn credibly affects overwintering success in H. armigera. In contrast, a considerable number of H. assulta pupae entered diapause well before autumn, even though those individuals had hatched from eggs deposited during the mid-summer. Thus, H. assulta appeared to prepare for overwintering earlier and more successfully than did H. armigera in this temperate zone. Differences in diapause induction between the sexes revealed in laboratory experiments with H. armigera were not detected under outdoor conditions.
