They occupy a very similar ecological niche, and thus compete for resources. By having a strong population of natives and EHs, the resources for AH are restricted, and makes their establishment more difficult.How are they a defence? Native wasps will be consumed by AHs, and the EHs will stay out of their way. Can't see any native insects are in a position to even slightly bother an AH.
Which is why by-catch is a problem, and a non-trapping wick bait is preferable.
