Immature Stages
of Diapriidae
Detailed information on immature
stages of Diapriidae is being acquired.
However, Clausen (1940) noted that the 1st instar larva (Fig. 117) is
robust in form and of the mandibulate type.
The head is very large, a bit flattened, and heavily sclerotized. It bears a pair of very large curved
mandibles. There are 12 body
segments; the last segment bears a pair of terminal lobes that have a number
of setae. Otherwise there are no
integument spines or setae. The 2nd instar larva (Fig. 117)
lacks the large, heavily sclerotized head of the preceding instar and is of
normal form. Neither this nor the 1st
instar possesses a tracheal system.
The supposed 3rd and final instar larva is elongated, with 12 body
segments, and possesses a complete tracheal system with 3 pairs of large
spiracles on the thoracic segments.
The contents of the host puparium are entirely consumed. The meconium is case by the prepupa, and
after the final molt the pupa lies with its head at the anterior end of the
puparium. Please CLICK on picture to view details:
