Description
Mass-rearing and augmentative release of hymenopterous parasitoids has been a component of area-wide management programs for several tephritid fruit flies, including pestiferous species of the genus Anastrepha (Cancino & Montoya 2008). Laboratory rearing of Doryctobracon areolatus (Szepligeti), a braconid larval-prepupal parasitoid of Anastrepha fruit flies, was first done in the United States in Florida in the late 1960s as part of an effort to biologically control the Caribbean fruit fly, Anastrepha suspensa (Loew) (Baranowski et al. 1993; Cancino et al. 2008). Although releases of D. areolatus for management of the A. suspensa in Florida have ended, laboratory rearing of D. areolatus is needed to produce parasitoids for establishment in Caribbean locations with pest fruit flies (Holler, unpublished data). The process of rearing, transporting, and releasing parasitoids can be simplified if irradiated fruit fly larvae are used as hosts (Sivinski & Smittle 1990). Larvae irradiated at an appropriate dose will not develop into adult flies, but are capable of supporting the development of a number of fruit fly-specific braconid parasitoids, including Doryctobracon crawfordi (Viereck) (Aluja et al. 2008; Cancino et a1.2008). In addition, parasitoids can be moved as pupae without transferring the pest. Therefore, tests were conducted to determine the effects of gamma irradiation of host larvae at a single dose on D. areolatus production and sex ratio, and on the ability of the host to complete development to adult.
