Family Parasitylenchidae

                                 Revised 01/22/26

Classification:

Phylum Nematoda

  Class Chromadorea

    Subclass Chromadoria

Rhabditida

 Tylenchina

Sphaerularioidea

A family of insect-parasitic nematodes, especially parasites of beetles and flies.

Damage to Hosts:

The most obvious effect of parasitism of bark beetles by Parasitylenchus spp is the reduction in egg production, presumably by damage to the female gonad. There does not appear to be similar damage to the male gonad (Massey, 1974).

Females of the face fly, Musca autunmalis visited both dung and cattle when infected, or lighly infected with Heterotylenchus autumnalis, however, they were found mainly in dung when heavily infected and wete less likely to visit cattle (Kaya et al., 1979).
