Physiological Indices of Maricultured Mussel Mytilus galloprovincialis Lamarck, 1819 in Istria,Croatia: Seasonal and Transplantation Effect          下载免费PDF全文

Transplantation of mussels to new aquaculture sites is currently being undertaken in Istria (Croatia) to increase production, minimize potential seasonal urban contamination, and secure safer seafood products. The purpose of this study was to determine the effects of season and transplantation on physiological indices (condition index and meat yield) of mussels, Mytilus galloprovincialis. Mussels were obtained from five aquaculture areas in Istria (central Lim Bay, Ra?a, Budava, Vabriga, and Pomer) and moved to a reference site in inner Lim Bay from April to July. Results showed that both season and transplantation affected physiological indices of mussels. Higher physiological indices were found in cultivated mussels from all areas in summer compared to spring, except in mussels from Vabriga and Pomer. In addition, higher physiological indices were found in mussels transplanted from central Lim Bay to the reference site in inner Lim Bay. Transplantation negatively affected physiological indices of mussels from Vabriga and Pomer, with no change in mussels from Ra?a and Budava. In conclusion, mussels from all areas exhibit satisfactory commercial results (≥15%) during the peak summer harvesting season. For most transplanted mussels, transplantation itself represents additional stress, bringing into focus adaptation processes, stock genetics, and favorable ecological conditions.  相似文献   

The occurrence and distribution of potato cyst nematodes in Croatia     

Dinka Grubišić  Ljerka Oštrec  Tanja Gotlin Čuljak  Sylvia Blümel 《Journal of pest science》2007,80(1):21-27

Potato cyst nematodes (PCN) Globodera rostochiensis (Wollenweber, 1923) Behrens, 1975 and Globodera pallida (Stone, 1973) Behrens, 1975 are the most troublesome pests of potatoes worldwide. Since 1968 there have been no investigations of the presence of PCN in ware potato lands in Croatia although these pests were recognised as an A1 plant-health quarantine species. After the first discovery of G. rostochiensis in the locality of Belica (Medjimurska County) in 2001, intensive monitoring of the distribution of PCN in Croatia started. In 2001 G. rostochiensis was detected in 55% of soil samples taken in ware potato lands. In 2002 G. rostochiensis was detected in 4.1% of soil samples and in 0.08% of soil samples in mixed populations with G. pallida. The pathotype Ro1 was found in all tested populations and Ro1 and Pa 2/3 were detected in populations from localities Vidovec, Ivanovec and Sivice. In 2003 G. rostochiensis was detected in 1.03% of soil samples, and also in 12.8% of soil samples collected in 2004. In 2003 cysts of G. rostochiensis were detected in several seed potato fields. These results indicate the urgent need for the application of further control measures to determine the presence and distribution of PCN in ware and seed potato lands in Croatia, in order to prevent the spread of PCN to non-infested areas. Integrated management strategies, neglected until 2001, have now been implemented and will prevent the build-up of infestation and replace the previous practices of monoculture, the use of short rotations and growing susceptible cultivars.  相似文献   

Effects of seed potato tuber treatment with imidacloprid on some soil and foliar insects in Croatia     

J. Igrc-Barčić  R. Dobrinčić  M. Maceljski  J. Barčić 《Journal of pest science》2000,73(2):41-48

The treatment of seed potato tubers by imidacloprid, as well as the standard granular insecticides applied in the furrow, did not, in four years of trials, sufficiently prevent damage from wireworms, noctuid larvae and mole crickets to potato tubers. The main reason for this failure is the spatial and temporal distance between the application of insecticides and the moment when their action is needed. On the other hand, the effects of imidacloprid applied as seed tuber treatment on the larvae of the Colorado potato beetle was very good: depending upon conditions, it lasted from at least 55, to 70 days at the most. It protected the foliage from any substantial damage from the entire first generation, and ensured high yields. Therefore a decision on seed tuber treatment with imidacloprid in Croatia should primarily depend upon the cost/benefit calculation based on damage expected from the CPB (or aphids), and not from soil insect pests.  相似文献   

Distribution and abundance of small rodents in Croatian forests     

J. Margaletić  M. Božić  M. Grubešić  M. Glavaš  W. Bäumler 《Journal of pest science》2005,78(2):99-103

The relative abundance and the population development of small rodents were investigated on 17 sites in Croatian forests from September 1999 through June 2003. Common snap traps were set for two or three nights along transect lines in different forest types. In 27,598 trap–nights, 2,151 specimens were trapped. Small rodents were present in up to 45% of the traps in pedunculate oak forests dominated by Quercus robur L. In common beech forests with a predominance of Fagus sylvatica L., the percentage of occupied traps reached 59%. At most sites the following species were dominant:Clethrionomys glareolus Schr., Apodemus agrarius Pall. and A. flavicollis Melch. Additionally, in a forest community of Carpino betuli-Quercetum roboris typicum R., the absolute number of small rodents was calculated by means of the standard minimum method. The minimum rodent density was observed in April 2003 with 11.63 n/ha (number of specimens per hectare). The maximum was reached in March 2001 with 82.03 n/ha. Near the same site, the absolute number of the small rodent population was estimated using the Y method in spring 2001 as approximately 101.34 n/ha. In general, the abundance of small rodents was dependent on the forest seed crop.  相似文献

Larssoniella duplicati n.sp. (Microsporidia, Unikaryonidae), a newly described pathogen infecting the double-spined spruce bark beetle, Ips duplicatus (Coleoptera, Scolytidae) in the Czech Republic     

J. Weiser  J. Holuša  Z. Žižka 《Journal of pest science》2006,79(3):127-135

Larssoniella duplicati n.sp. infects the midgut muscularis, the Malpighian tubules, and the ovaries of adult Ips duplicatus (Sahlb.) in the Czech Republic. The microsporidian attacks up to 50% of the population. Oval spores of two sizes, 3–3.5×1.5–2 and 2–2.5×1.5 μm have the polar filament coiled in 6/7 coils, representing primary and environmental spores, respectively. In early sporogony the young spores produce long electron dense threads and tubules of secretions, which remain fixed around the spore and avoid their free release during dissection of infected hosts. The microsporidian was not found in associated bark beetles such as Ips typographus (L.), or I. amitinus (Eichh.) and others.  相似文献
