Influence Of Temperature On Life Table Parameters Of The Predaceous Mite Euseius Finlandicus (Oudemans) (Acari: Phytoseiidae), İsmai̇l Kasap Jan 2009

Influence Of Temperature On Life Table Parameters Of The Predaceous Mite Euseius Finlandicus (Oudemans) (Acari: Phytoseiidae), İsmai̇l Kasap

Turkish Journal of Agriculture and Forestry

This study determined the differences in development time, survival, and fecundity of Euseius finlandicus (Oudemans) (Acari: Phytoseiidae) when feeding on Tetranychus urticae (Koch) (Acari: Tetranychidae) together with birch pollen at 16, 20, 25, and 30 ± 1 °C, 65 ± 10% RH, and 16:8 photoperiod under laboratory conditions. Total development times for E. finlandicus were 29.48, 18.15, 7.28, and 5.90 days for females and 28.16, 17.54, 7.03, and 5.81 days for males at 16, 20, 25, and 30 ± 1 °C, respectively. Total egg production was highest (30.53 eggs) at 25 °C, whereas daily egg production was highest (1.80 eggs) …


The Effect Of Different Temperatures On Autolysis Of Baker’S Yeast For The Production Of Yeast Extract, Hasan Tangüler, Hüseyi̇n Erten Jan 2009

The Effect Of Different Temperatures On Autolysis Of Baker’S Yeast For The Production Of Yeast Extract, Hasan Tangüler, Hüseyi̇n Erten

Turkish Journal of Agriculture and Forestry

This study aimed to determine the optimum autolysis conditions for the production of yeast extract, which is used to give a meaty flavor to food products and to increase their nutritional value. Autolysis was induced by incubating baker’s yeast cell suspensions at different temperatures (45, 50, 55, and 60 °C) with a reaction time ranging from 8 to 72 h. Content and yield of total solids, \alpha-amino nitrogen (\alpha-AN), and protein were determined. Yeast extract powder was obtained by drying liquid yeast extract in a pilot scale spray drier. Sensory analysis was performed by adding the yeast extract powder at …


The Effects Of Different Temperatures And Diets On The Biology Of Cales Noacki Howard (Hymenoptera: Aphelinidae), A Parasitoid Of The Citrus Woolly Whitefly, Gonca Vatansever Saki̇n, M. Rifat Ulusoy Jan 2009

The Effects Of Different Temperatures And Diets On The Biology Of Cales Noacki Howard (Hymenoptera: Aphelinidae), A Parasitoid Of The Citrus Woolly Whitefly, Gonca Vatansever Saki̇n, M. Rifat Ulusoy

Turkish Journal of Agriculture and Forestry

The biology of Cales noacki Howard (Hymenoptera: Aphelinidae), a particular parasitoid of the woolly whitefly, Aleurothrixus floccosus Maskell (Homoptera: Aleyrodidae), was investigated under laboratory conditions, where the effects of different temperatures [18, 22, 26, 30, 34, 18/26, 26/34 °C] and the longevity of adults on different diets [sugar water (10%), water with honey (10%), water, honeydew of A. floccosus, 1^{st} instar larvae of A. floccosus, or no food] were observed. The longest developmental time of C. noacki was identified at 18 °C (F: 49.0 and M: 48.5 days) and the shortest time was at 26 and 30 °C constant temperatures …
