Since 1986, the suppression strategies implemented
against Ceratitis capitata
through the National Fruit Fly Control and Eradication Program in the province
of San Juan (ProCEM San Juan), have been based on integrated use of SIT,
cultural and chemical controls, plus a quarantine system. In April/2008, the
Biological Control has been incorporated into control activities of the ProCEM
San Juan. The first step was the establishment of a colony of the parasitoid Diachasmimorpha longicaudata on
third-instar larvae of tsl C. capitata
strain VIENNA 8 at the San
Juan facility. The rearing cages of D. longicaudata were held in a rearing 5% RH, and
12:12 (L:D) h photoperiod.± 1 ºC,
65 ±room
with 24 This parasitoid colony was derived from a strain previously
reared on late-third instar Anastrephafraterculus larvae at the
Insectary of PROIMI-CONICET, Biological Control Division, located in San
Miguel de Tucumán, Argentina.
However, the colony of D. longicaudata
introduced to Argentina was obtained
from a strain already adapted to laboratory conditions using Anastrepha ludens (Loew) larvae as a host
in the Biological Control Laboratory of the Mexicos
Moscamed-Moscafrut National Program in Metapa
de Dominguez, Chiapas, México.
Financial support to introduction and establishment of D. longicaudata in Argentina
was provided by the Agencia Nacional de Promoción Científica y Tecnológica,
Ministerio de Ciencia, Tecnología e Innovación Productiva de Argentina (Grants
PICT/97 n° 01236 and PICTO/02 n° 12909). Currently, quality control parameters
for D. longicaudata reared on
tsl C. capitata strain is being analyzed in order to evaluate the
rearing process and the final product. In a second phase, is planned a mass
rearing of D. longicaudata to
reach a weekly production of 5 million parasitoids. In a third phase, the
parasitoids will be released in some ecologically isolated fruit-growing areas
of San Juan in combination with sterile Medfly releases in order to evaluate
parasitoid efficiency once released in the field. Medfly eradication might be
reached in those areas with the use of environment-friendly technologies such
as SIT and Biological Control.
