Parasitoid wasps like Trichogramma nubilale show varied host-finding efficiency based on surface complexity. This behavior has a genetic component, influenced by maternal or dominance effects, impacting foraging evolution.

Area of Science:

  • Behavioral Ecology
  • Insect Behavior
  • Evolutionary Biology

Background:

  • Surface structural complexity significantly impacts host-finding efficiency in parasitoids.
  • Parasitoid behavior is crucial for biological control and pest management strategies.

Purpose of the Study:

  • To investigate host-finding efficiency of Trichogramma nubilale on simple versus complex surfaces.
  • To evaluate the genetic basis of variation in host-finding behavior using a quantitative genetics approach.

Main Methods:

  • A full-sib/half-sib mating design was employed to assess genetic variation.
  • Parasitism rates on simple and complex surfaces were recorded for Trichogramma nubilale.
  • Repeatability and genetic variances (additive, maternal, dominance) were estimated.

Main Results:

  • Trichogramma nubilale parasitized 63.8% of egg masses on simple surfaces versus 36.2% on complex surfaces.
  • Significant repeatable variation in host-finding efficiency among females was observed (repeatability = 0.59).
  • Additive genetic variance was not significant, but maternal plus dominance variance was significant (P<0.036), accounting for 48.8% of total phenotypic variance.

Conclusions:

  • Structural complexity influences parasitoid host-finding, reinforcing previous findings.
  • Maternal or dominance effects play a significant role in the inheritance of host-finding behavior.
  • These genetic effects can lead to complex evolutionary consequences for foraging traits in parasitoids.
