Immature Stages of Signiphoridae
Detailed information on immature stages of Signiphoridae is being
acquired. However, Clausen (1940)
noted that the egg of Thysanus
elongatus Gir, a external
hyperparasitoid of Pseudococcus
maritimus Erichson, is 0.22
mm. Long X 0.07 mm. in max. Width, elongated oval in form, and slightly
curved. They bear a distinct peduncle
at the anterior end. The egg is very
large in relation to the size of the parent female, which measures only 0.7
to 0.9 mm. In length. The meconium is
case upon completion of larval feeding, and a portion of it serves to attach
the tip of the abdomen of the pupa to the wall of the cell. References: Please refer to <biology.ref.htm> [Additional
