SUMMARYThe longevity of male and female Megaselia haltherata, 75% of parasitised by the nematode Howardula husseyi, was studied for 16 days at 20‐ 21.5 OC. A statistical model fitted to the data indicated that parasitism reduced fly longevity significantly; predicted times to 50% mortality were about 6 days shorter for parasitised males, but only 2 ...

Abstract In this study, prevalence, distribution and seasonal dynamics of Howardula phyllotretae Oldham, parasitic nematode of two flea beetles, Phyllotreta undulata and P. atra in Middle and East Blacksea Region of Turkey were investigated. Nematode infection was observed in all localities investigated during the study.

Summary Deladenus nitobei, a hexatylinid species, is a parasite of the wood wasp Sirex nitobei and a fungal feeder, i.e., the nematode parasitises the wasp to be carried to a new environment (a dead tree) where it propagates after feeding on Amylostereum areolatum, a fungus mutualistically associated with the wasp.

Abstract The dimorphic spermatozoa of the insect-parasitic nematode Deladenus sp. (Tylenchomorpha: Sphaerularioidea: Allantonematidae) were studied for the first time with a transmission electron microscope (TEM). The immature spermatozoa from the testis of mycetophagous males are 10-12 μm diam.

Histological examination of pathogical changes caused by allantonematid nematodes infecting bark beetles was conducted using beetles collected from Nopiming Provincial Park and Belair, Whiteshell, and Agassiz provincial forests in Manitoba. Nematodes were classified into three groups according to the pattern and nature of damage caused to their hosts.

[A new nematode (allantonematidae) parasite of Heliophilus (T diptera, syrphidae)].
Acta tropica, 1976For the second time, the authors have found a new entomophagous nematode parasitic in Syrphidae. The first species, which was described as Syrphonematidae nov. fam., is living in the duct of various aphidophagous species of Syrphidae. This one has been found in the hemocoel of adults of Helophilus trivittatus Fabricius and H.
