Dusona juvenilis is a species of parasitic wasp belonging to the family Ichneumonidae, subfamily Campopleginae. [1] It is a parasitoid of Eupithecia haworthiata larvae. [2]
Head, antennae and thorax black. Second abodominal segment red on the posterior 0.1 – 0.3, third segment extensively red and forth segment black but rarely marked red laterally, gaster otherwise black. legs varying between yellow and black, front and middle legs usually brighter. Maxillary palps yellow or yellowish red. Mandibles marked with yellow. Epiplueron of the third tergite not separated by a crease. Size 7–9 mm, 26–28 flagellomeres in females, 28–31 in males. Ovipositor index 1.3. Dusona juvenilis can be distinguished from the very similar species D. aemula by the length of the ovipositor and that pleural part of the epicnemial carina being almost completely obliterated, usually with only some wrinkles present medially and/or subdorsally. [3] [4]
Dusona juvenilis is univoltine. It is associated with Clematis vitalba since this is the host plant to the host. Flight period is between June and September. [2]
Dusona juvenilis is known from a large portion of the Palearctic region: Austria, Belarus, Bulgaria, Finland, France, Germany, Georgia, Greece, Italy, Netherlands, Norway, Poland, Russia (including Siberia), Spain, Sweden, Turkey, Ukraine and United Kingdom. [2]
Sawflies are wasp-like insects that are in the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
The Ichneumonidae, also known as ichneumon wasps, ichneumonid wasps, ichneumonids, or Darwin wasps, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species described as of 2016. However, this likely represents less than a quarter of their true richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, distribution, and evolution. It is estimated that there are more species in this family than there are species of birds and mammals combined. Ichneumonid wasps, with very few exceptions, attack the immature stages of holometabolous insects and spiders, eventually killing their hosts. They thus fulfill an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control.
Campopleginae is a large subfamily of the parasitoid wasp family Ichneumonidae with a world-wide distribution. Species in this subfamily have been used in the biological control of the alfalfa weevil, clover weevil, various species of Heliothis, oriental army worm, European corn borer, larch sawfly, and others.
