Abstarct
Laboratory studies were conducted on rearing the parasitoid B.
brevicornis Wesm. on larvae of the alternate host Ephestia kueniella
Zellar, and included the following: 1) Determining the ratio of adult
parasitoid to the number of alternate host 4th instar larvae. 2)
Determining the optimum sex ratio for parasitoid laboratory rearing at the rate
of 15 larvae of alternate host. 3) Extending of the parasitoid storage period to
exceed 45 days by exposing it to cold temperature of 2 ºC under laboratory
conditions or under prevailing cold winter conditions. Data revealed that the
optimum parasitoid/alternate host ratio was pairs of adult parasitoid to larval
host which produced 38 adult parasitoids with 73 male: 27 female ratio.
Moreover, neither storage at low temperature nor exposing to natural conditions
prolonged the parasitoid storage periods more than 45 days. Field release rate
between 100-150 female/donum (2500 m2) have reduced the number of
live larvae at different release locations in Iraq.
