• Diadromus

  pupal parasitoid wasps

  Diadromus is a genus of ichneumonid wasps comprising over two dozen species distributed across Europe and North America. Species in this genus are endoparasitoids, primarily attacking lepidopteran hosts at the pupal stage. Several species, notably D. pulchellus and D. collaris, have been extensively studied for their biological control potential against agricultural pests including leek moth and diamondback moth. The genus exhibits complex host-finding behaviors mediated by volatile chemical cues and shows variable relationships with symbiotic viruses.
