ever, this may merely be a reflection of the extent to which the cuticle has been reabsorbed at the t ime of fixation since the cuticles of all these Lts are part ial ly reabsorbed dur ing moult ing. Also, the cuticle of the L~ of O. phyllobia appears to be structurally more complex than that of A. agrostis since it has a distinct striated basal layer (Fig. 1A, D) which is reabsorbed at a later...
متن کاملActivity and Survival of Orrina phyllobia: Preliminary Investigations on the Effects of Solutes.
The motility and survival of Orrina phyllobia fourth-stage juveniles (J4) were examined in NaCl, sucrose, and synthetic soil solutions. Synthetic soil solutions (SSSs) contained Na, K, Ca(2), Mg(2), Cl, and NO at relative concentrations identical to those in a known agronomic soil. Nematode activity was dependent on solute composition and on water potential. In all solutions, motility ceased at...

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...
متن کاملObservations on development of the gonad and on reproduction in Aphelenchus avenae.
Nuclear changes occurring in male and female gonads of Aphelenchus avenae during postembryogenesis were studied in relation to time and feeding periods on Rhizoetonia solani. Development of the female gonad was similar to that in other nematode species, but development of the male gonad followed the growth pattern of female rather than male gonads. This deviation was explained by the assumption...
متن کاملChanges in External Egg Traits of Chickens during Pre- and Post-Molting Periods
481 fresh fertilized eggs of three Kurdish local chickens (Black with brown neck, White with shank feathering, and White with non-feathering shank) were collected at pre-molting (355 eggs) and post-molting (126 eggs) stages to evaluate external egg traits. A venine caliper was used to determine the length and breadth of eggs to calculate Shape index. Results indicated that egg weight increased ...
