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...

Experiments were conducted to determine the effects of plant confinement, soil type, watering practices, stage of seed germination, inoculum level, and method of applying inoculum on stem nematode (Ditylenchus dipsaci) infection of alfalfa (Medicago sativa) seedlings grown in soil. Results indicated that (i) confining seedlings together with the nematodes in small vials offered no advantage ove...

spective haptenic sugars prevented their adsorption by the gelatinous nlatrix or the egg shells, whereas incubation with sugars other than the correct hapten inhibitor did not interfere with binding of the lectins. These last findings lend support to the idea that the described lectin-binding pat tern was not a result of nonspecific adsorption or uptake by the gelatinous matr ix or the egg shel...
