Life cycle and host range of the gall-forming moth, Meskea horor (Lep.: Thyrididae), and its suitability as a biological control agent for Sida acuta and S. rhombifolia (Malvaceae)
Entomophaga 42 (3), 393-403
Abstract: The life cycle of the moth, Meskea horor Dyar and its host specificity to Sida acuta and S. rhombifolia were investigated. Moths emerge early in the morning and are usually inactive during the day. Feeding by the adults in the field was not observed. However, those in the laboratory fed on flowers of S. acuta, S. rhombifolia and Hibiscus sabdarifa, and drank water or dilute honey solution. Eggs are mainly laid on the underside of leaves. Larvae of M. horor form galls in the stems of S. acuta and S. rhombifolia which retard plant growth and flowering. Pupation occurs within the gall. The development time from egg to adult was 192 days and the adults lived for 11 to 14 days. Forty-eight plant species were tested to determine the host range of M. horor. Adults emerged from seven species of plants in the family Malvaceae and larvae formed galls but died before pupating on a further 17 species. M. horor is considered to have too broad a host range to be used as a biological control agent for S. acuta and S. rhombifolia.
