cots in the family Commeliaceae. The basic morphology of these plants appears to favor root-knot nematode development in aboveground plant parts. Leaves of both plants develop in the crown near the soil; they are large, 20-30 cm long, and densely arranged so that nematodes on younger leaves are protected from direct solar irradiation. The dense pubescent foliage, especially the convoluted young...

Calorie values for a wide biological selection of nematodes, determined with a microbomb calorimeter, ranged from 3.86 to 6.85 Kcal/g. The mean of 5.095 Kcal from 16 species was lower than means recorded in three previous studies of other invertebrate groups. The nematode values were skewed to the lowest limit. Larvae of Ditylenchus dipsaci showed lower calorie values after storage, and the cal...

White flagging of alfalfa, Medicago sativa 'Ranger, found associated with Ditylenchus dipsaci in the Columbia River Basin was observed in northern Utah during 1971. This is a report on chloroplast changes, induced by D. dipsaci in alfalfa leaves, as observed with an electron microscope. Leaves from alfalfa plants infected with D. dipsaci were either devoid of normal pigmentation or displayed va...

In this study, we aimed to determine the nematode diversity in soils from olive orchards İzmir, Manisa, Çanakkale, and Balıkesir provinces. For purpose, a survey was carried out 2021-2022; each orchard, soil samples were collected 0-60 cm depth, nematodes extracted by modified Baermann Funnel method. Thirty-seven genera of (Achromodora, Acrobeles, Acrobeloides, Alaimus, Aphelenchus, Aphelenchoi...
