Target pest: Paropsis charybdis (Coleoptera: Chrysomelidae), eucalyptus tortoise beetle
Agent introduced: Froggattimyia spp. (Diptera: Tachinidae)
1934?, 1935?, 1964
Cameron et al. (1989) â€“ in February 1934 a small number of late instar larvae of various Paropsis species were imported from, Australia, which yielded â€˜a quantity of tachinid pupariaâ€™. In March 1934, 24 tachinid puparia were received from Australia, and another 29 in January 1935. Apparently two distinct species were present in all three consignments. A number of tachinids were reared but there were no field releases. In February 1964 a small consignment of Froggattimyia spp. pupae, bred from Chrysophtharta bimaculata, was received from Canberra, Australia; they were heavily hyperparasitised and it is not recorded if any tachinids emerged.
Cameron et al. (1989) - not released.
