In the presence of potato plants cv. Golden Wonder, Globodera pallida exhibited delayed in-soil hatch compared to that of G. rostochiensis, with significantly fewer G. pallida second-stage juvenile nematodes hatching in the first two weeks, though the difference disappeared after four weeks. Inoculation of potato plants with arbuscular mycorrhizal fungi eliminated this delay in G. pallida hatch...

It is recognized that cool egg storage for 8 d or longer, commonly employed in broiler parent and commercial layer production, reduces hatchability. In this study, we investigated the efficacy of short periods of incubation during egg storage (SPIDES) in the restoration of hatchability of broiler hatching eggs stored for 21 d. Prolonged cool storage reduced hatchability of untreated eggs from 9...

Variations in otolith patterns, sizes and body morphometrics of jack mackerel Trachurus japonicus juveniles were investigated. Under transmitted light, translucent (W(t)) and opaque otoliths (W(o)) were detected in juveniles collected from Wakasa Bay between July 2005 and April 2006, whereas only opaque otoliths (G(o)) were detected in Goto-nada Sea individuals between May and June 2006. Three ...

J. Entomol. Sci. 43(1): 86-94 (January 2008) Abstract Addition of 3 DNA-gyrase inhibitors (i.e., novobiocin, nalidixic acid and oxolinic acid) individually to the NI (New and Improved) oligidic diet for plant bugs was investigated to assess their effect on the biological fitness of Lygus hesperus Knight (Heteroptera: Miridae). Biological fitness was measured by the number, biomass, sex ratio, d...

Eggs, either dispersed or in masses, and second-stage juveniles (J2) of Meloidogyne incognita were exposed to different concentrations of ammonium ions in a nutrient agar medium upon which excised tomato roots were growing. Egg hatch and J2 penetration of the roots was slowed or inhibited at high (54 and 324 mg/liter) but not at low (1.5 and 9 mg/liter) concentrations of ammonium nitrate. The e...

A B S T R A C T The role of glucagon in the metabolic adaptation to prolonged fasting in man has been examined. Plasma immunoreactive glucagon was determined during 6-wk fasts and during infusion of exogenous glucagon using an assay which minimized nonpancreatic immunoreactivity. Plasma glucagon concentrations rose twofold to a peak on the 3rd day of fasting and then declined thereafter to a le...
