& Birch, L.C. different virus diseases, which form a spectrum from threatening to new and emerging because of a changing vector picture. – Ann. : Braconidae) is determined as the most common parasitoid species in the survey conducted to detect parasitoid species found in citrus trees and herbaceous species in the Eastern Mediterranean Region. (1977) and Blackman &, is found on these two host plants during the flowering time and of the plant. L, generations on each variety before starting the, 24 h were transferred individually by camels-, where a and b are estimated parameters and the data are, has 11 host plants in east Mediterranean Re. (Boyer de Fonscolombe) (Homoptera: Aphididae). SPSS, Introductory Statistics Stude, Blackman, R.L., & Eastop, V.F. Leaves can be damaged to such an extent that they wilt and fall off. ... For example, Komazaki (1982) found that the intrinsic rate of natural growth is highest at 22 ° C for A. gossypii and 27 ° C for A. spiraecola. Soc. A. gossypii reproduction is mostly asexual with either alate or apterous females. Life Cycle: Aphis gossypii is viviparous throughout the year. All the host plants were, All the determined host plants are shrubs a, Rosaceae, Caprifoliaceae and Rhamnaceae. The impact of these ingress events is determined by the potential for secondary spread, and the pathogen and vector reservoirs in other crops. aphid species were determined in citrus of Mediterranean region of Turkey. 93(4): 874-883. Young growing shoots with D. citri eggs present were identified, and live, Prunus crops are not the only fruit crops harboring serious viruses not found in the North American continent. Life cycle (marked by dark colours) of, 270.709, df = 3, 159; FP.coccinea Developm. The Water Cu. of Chicago Press, Chicago and London: 782 pp. The prey consumption by D. tamaninii adults over their entire longevity showed according to temperature, prey age group and sex of the predator significant variations. host. Through this study, five aphid species were identified, among them Aphis spiraecola Patch, 1914 was the most numerous. To predict the northern limit of the spread of the insect, I examined temperature-dependent development and determined the developmental zero of the insects in a laboratory Eggs and nymphs were reared at temperatures of 15.0 to, The present study aimed to investigate the prey consumption by the predatory bug Dicyphus tamaninii Wagner (Heteroptera: Miridae) during its development as well as the entire longevity with 1-2- and 4-5-day-old Aphis gossypii Glover (Homoptera: Aphididae) as prey at a temperature of 25 ± 1°C and 18 ± 1°C. Meyer, J.S., Ingersoll, C.G., Mcdonald, L.L. 1986. The wingless morphs are very variable in color, mostly from yellowish to green, occasionally gray. With the establishment of the brown citrus aphid (Toxoptera citricida) in Florida in 1995, the threat of spread of severe stem pitting isolates of citrus tristeza virus has increased exponentially along with projected loss of an estimated 18 million trees from tristeza-induced decline. Like most aphids, A. gossypii is an important virus vector: it can transfer about 70 different types, some of which may cause more damage than the aphid itself. Longevity, offspring per reprodu, ) is the only statistics that adequately summ, of an animal relative to its capacity of in, and 0.2891 on Washington) among the all the tested, ment on this temperature (Table 4.).

The experiments were conducted at five constant temperatures (12, 17, 22, 27 and 32±1°C), 65% RH, 16 h (8-10 klux) daily artificial light in temperature cabinets.
