Abstract
An entomophilic nematode, Thripinema nicklewoodii (Tylenchida: Allantonematidae) and an endoparasitic wasp, Ceranisus sp. (Hymenoptera: Eulophidae) were recently recovered from western flower thrips (WFT) in California. Observations suggest nematode transmission into WFT occurs while the thrips feed on the plant. Females parasitized by the nematode appear to be reproductively sterile. The parasitic wasp was collected in samples of thrips-infested alfalfa and garden roses. Under laboratory conditions it predominantly oviposited into first instars, resulting in WFT death at the pre-pupal stage. Host-feeding was common. Identification of the wasp to the species level remains undetermined.
