Different alternative hosts can reduce or even avoid pre-imaginal conditioning of parasitoids in mass production programs. Spodoptera cosmioides(Walker) (Lepidoptera: Noctuidae) may be an alternative host for mass rearing the parasitoid Palmistichus elaeisisDelvare & LaSalle (Hymenoptera: Eulophidae). The objective of this study was to evaluate the parasitism, emergence, egg-to-adult period, progeny size, sex ratio, and consumption of host tissue per individual of P. elaeisisproduced using S. cosmioidespupae in the laboratory. Newly formed S. cosmioidespupae were weighed, individualized in glass tubes and each one was exposed to six newly emerged P. elaeisisfemales during 48 h. These pupae were transferred to plastic pots until the emergence of P. elaeisisadults. Palmistichus elaeisisparasitized and emerged from 100.0 % and 87.5 % of the S. cosmioidespupae, respectively. The egg-to-adult period of P. elaeisiswas 24.28 ± 0.18 days, with 109 ± 2 individuals emerging per host pupae. Mass consumption of the host was 2.56 ± 0.01 mg per parasitoid emerged. This is the first report of P. elaeisisparasitizing and developing in S. cosmioidespupae. The ease of rearing S. cosmioideswith an artificial diet, and the high parasitism, emergence, and progeny size of P. elaeisissupport the suitability of this alternative host to mass-rearing this parasitoid. |
