Abstract(s)
Following a previous survey of oophagous parasitoids at Ribeira do Guilherme, São Miguel, Açores, a two-year trial for Lepidoptera eggs was undertaken in order to study their dynamics. Between Novemher
1991 and November 1993 only two parasitoids were discovered: Telenomus sp. (Scelionidae) and T. cordubensis. During winter no eggs parasitized by Trichogramma were collected. From April to November 1992 and June to Novemher 1993, eggs parasitized by Telenomus sp. and T. cordubensis were detected in the field. Telenomus sp. always appeared earlier in the season than Trichogramma. In the
present paper, the plant/host/parasitoid interactions are discussed and a comparative analysis is made between the two-year field data.
