Effects Of Antimicrobial Agents On The Survival And Development Of Larvae Of Pimpla Turionellae L. (Hymenoptera: Ichneumonidae) Reared On An Artificial Diet, Kemal Büyükgüzel, Şevki̇ Yazgan Jan 2002

Effects Of Antimicrobial Agents On The Survival And Development Of Larvae Of Pimpla Turionellae L. (Hymenoptera: Ichneumonidae) Reared On An Artificial Diet, Kemal Büyükgüzel, Şevki̇ Yazgan

Turkish Journal of Zoology

The effects of 13 antimicrobial agents that have different structures and modes of action, on the survival and development of the hymenopterous endoparasitoid, Pimpla turionellae L., were investigated by rearing the larvae aseptically on chemically defined synthetic diets. These effects varied according to their kind and dietary levels. The agents tested exerted their effects generally during the post-larval development of the insect. The post-larval survival and development were negatively affected by most of the agents tested at certain levels. The antimicrobial agents tested also affected the larval development but had no significant effects on the larval survival of the insect. …

Effects Of Some Dna Gyrase Inhibitors On The Survival And Development Of Pimpla Turionellae (Hymenoptera: Ichneumonidae) Larvae Reared On An Artificial Diet, Kemal Büyükgüzel Jan 2002

Effects Of Some Dna Gyrase Inhibitors On The Survival And Development Of Pimpla Turionellae (Hymenoptera: Ichneumonidae) Larvae Reared On An Artificial Diet, Kemal Büyükgüzel

Turkish Journal of Zoology

The effects of novobiocin, nalidixic and oxolinic acids, which are potent antibacterial agents, on the survival and development of the hymenopterous endoparasitoid Pimpla turionellae L. were investigated alone by rearing the larvae aseptically on chemically defined synthetic diets. The percentage of fifth instar larvae was not significantly affected by the diets with different levels of the antibiotics used in the study. A diet containing the lowest level of novobiocin significantly increased the yields of pupae and adults. This level also significantly shortened the developmental time for fifth instar, but had no significant effect on the complete development of the larvae …

Degradation Products Of Adenine Nucleotide In Rainbow Trout (Oncorhynchus Mykiss) Stored In Ice And In Modified Atmosphere Packaging, Yeşi̇m Özoğul, Fati̇h Özoğul Jan 2002

Degradation Products Of Adenine Nucleotide In Rainbow Trout (Oncorhynchus Mykiss) Stored In Ice And In Modified Atmosphere Packaging, Yeşi̇m Özoğul, Fati̇h Özoğul

Turkish Journal of Zoology

The breakdown products of adenosine triphosphate (ATP) were separated using a rapid HPLC method. The K-value, Ki-value and H-value were also determined as a means of evaluating the quality of rainbow trout held in ice and modified atmosphere packaging comparing with sensory and microbiological analysis in terms of fresh fish quality. Results from the present research indicated that modified atmosphere did not extend the shelf life of trout but inhibited microbial growth compared to ice storage. However, there was no significant difference (P>0.05) between the two conditions. K and Ki-values provided a useful freshness index of fish for both …

Androgenesis: The Best Tool For Manipulation Of Fish Genomes, Minal P. Bhise, Tariq A. Khan Jan 2002

Androgenesis: The Best Tool For Manipulation Of Fish Genomes, Minal P. Bhise, Tariq A. Khan

Turkish Journal of Zoology

Androgenesis involves the development of an organism with only paternal chromosomes. The induction of androgenesis using diploid sperm, highly effective UV-irradiation of egg, dispermy using heterologous eggs, the possibility of producing supermales for all male production and the recovery of cryopreserved sperm are recent technological developments in androgenesis in fish. However, few researchers have successfully produced viable diploid androgens in fish. The authors made an attempt to induce androgenesis in the common carp (Cyprinus carpio L.) and the results are discussed along with the potential applications of androgenesis in conserving fish genomes and current knowledge on inducing androgenesis in fish.
