Oviposition effects

Host marking pheromones are important in many species of parasitic hymen-optera, because they ensure that a female parasitoid focuses on non-parasitized hosts. This, in turn, ensures a more effective use of limited host resources. Marking pheromones can be internal (injected into the host at the time of oviposition) or external (applied to the host during inspection and/or ovipo-sition). The internal markers can be detected by sensory hairs on the parasitoid ovipositor [11]. The internal markers often also delay the development of the host. 

Experimental studies with southern armyworm larvae and thiocyanate — one of the in vivo cyanide metabolites — showed that 5000 mg thiocyanate/kg diet reduced pupation by 77%, completely inhibited oviposition, and reduced adult emergence by 80% (Brattsten et al. 1983), strongly suggesting that thiocyanate poisoning is the primary effect of high dietary cyanide levels in southern army worms.

In angelfish, Pterophyllum scalare, chemical cues from males stimulate and accelerate spawning in the female. Simultaneous chemical and visual cues stimulate oviposition even more, suggesting an additive effect of the two modalities (Chien, 1973).

The insect can be controlled with insecticides applied after oviposition. However, the absence of an economic effect mitigates against their use. There have been no reports of significant damage to Jerusalem artichokes.
