External Morphology and Development of Immature Stages of Elachertus Scutellatus (hymenoptera: Eulophidae) in Florida: the First North American Record

چکیده

The first North American record for Elachertus scutellatus , a parasitoid of Calpodes ethlius Stoll, occurred August 1999, in Florida. A simple rearing protocol was established to allow the morphology and development of this wasp to be examined. The egg and larval morphology and development of E. scutellatus resemble other Elachertus species. The freshlyecdysed pupa, on the other hand, is rare among parasitoids in that it secretes a fluid from its anus which, when dry, fastens the pupa to its substrate. The death of the colony after eight months has many possible explanations including a laboratory-induced castration, inappropriate food source(s), and pathogenic infection.
