Biological aspects of Tiracola grandirena (Herrich-Schäffer, 1868) (Lepidoptera: Noctuidae): a polyphagous armyworm

Abstract

We studied the biology of Tiracola grandirena (Herrich-Schäffer, 1868) (Lepidoptera: Noctuidae: Hadeninae) at 25 ± 1 °C, 70 ± 10% RH and 14 hours of photo phase. Three experiments, using 150 larvae each, were conducted for the larval stage. In the first, used to assess the duration and survival of all stages, insects were reared individually and fed an artificial diet (Grenee). In the second, individuals were also reared separately, but were fed leaves of 10 plants from different families. In the third, the larvae were not individualised, the food plants were rotated such as to provide three plant species every 48 hours. In the first experiment, the viability of the eggs, larvae, pupae and prepupae was 91.9, 94.7, 32.49 and 43.5%, respectively. The average duration of the egg, larvae, prepupae, pupae and adult were 6.0, 25.3, 25.7, 21.4 and 12.7 days, respectively. The prolonged prepupal period indicates that T. grandirena can develop larval (prepupal) diapause. The results of the experiments with different host plants showed that T. grandirena is polyphagous at species, population and individual level.Keywords: caterpillar, developmental biology, prepupal diapause, Hadeninae.

Green cutworm Anicla ignicans (Lepidoptera: Noctuidae): Identity, geographical distribution, immature morphology, host plants and biology in controlled conditions

“…Regarding the duration of instars (Table 2), as observed for most representatives of Noctuidae (Montezano et al 2016(Montezano et al , 2019bSpecht et al 2014Specht et al , 2020, it was found that the first instar (where the larva hatches, uses up its 'yolk' reserves, feeds on the eggshell and then begins feeding on the host plant tissue or artificial diet [Adler & Dial 1989]) is relatively longer than the others, where it is observed a progressive increase in development periods until the last (sixth instar), longest of all, which still presents, at its end, the prepupae period (Table 2).…”

Diversity of insects associated with the fruits of four tree species of Lauraceae from Los Tuxtlas region, Mexico: an annotated and illustrated taxonomic list

“…To our knowledge, most of the insects that feed on Lauraceae and are parasitized by tachinids belong to Lepidoptera. The tachinid parasitoid reports include lepidoptera hosts found in fruits of Cinnamomum (Kan et al, 2003), feeding on leaves of Ocotea veraguensis (Corrales & Epstein, 1997), Nectandra megapotamica (Specht et al, 2014), Nectandra sinuata (Myshondt, 1975), and feeding on unspecified structures of avocado (González-Herrera & Soto-Rodríguez, 1998). Furthermore, tachinids have also been reported as floral visitors of several Lauraceae including avocado (Carabalí-Banguero et al, 2018;Castañeda-Vildózola et al, 1999;Wysoki et al, 2002), Sassafras albidum (Tooker et al, 2006), and Ocotea catarinensis (Montana, 2018).…”
