Top 20 environmental weeds for classical biological control in Europe: a review of opportunities, regulations and other barriers to adoption   总被引：4，自引：3，他引：4

Classical biological control remains the only tool available for permanent ecological and economic management of invasive alien species that flourish through absence of their co‐evolved natural enemies. As such, this approach is recognized as a key tool for alien species management by the Convention on Biological Diversity (CBD), the European and Mediterranean Plant Protection Organization (EPPO) and the European Strategy on Invasive Alien Species (ESIAS). Successful classical biological control programmes abound around the world, despite disproportionate attention being given to occasional and predictable non‐target impacts. Despite more than 130 case histories in Europe against insect pests, no exotic classical biological control agent has been released in the EU against an alien invasive weed. This dearth has occurred in the face of increasing numbers of exotic invasive plants being imported and taking over National Parks, forests and amenity areas in this region, as well as a global increase in the use of classical biological control around the world. This paper reviews potential European weed targets for classical biological control from ecological and socioeconomic perspectives using the criteria of historical biological control success, taxonomic isolation from European native flora, likely availability of biological control agents, invasiveness outside Europe and value to primary industry and horticulture (potential for conflicts of interest). We also review why classical biological control of European exotic plants remains untested, considering problems of funding and public perception. Finally, we consider the regulatory framework that surrounds such biological control activities within constituent countries of the EU to suggest how this approach may be adopted in the future for managing invasive exotic weeds in Europe.  相似文献

Pharmacokinetics of probenecid in sheep     

V. H. GUERRINI  L. J. FILIPPICH  P. B. ENGLISH  JENNY SCHNEIDER  G. R. CAO  D. W. A. BOURNE 《Journal of veterinary pharmacology and therapeutics》1985,8(2):128-135

Six Merino ewes were given 1 g (27 g/kg) probenecid by the intravenous (i.v.), intramuscular (i.m.) and subcutaneous (s.c.) routes. After i.v. injection, the biological half-life was 1.55 h and apparent volume of distribution at the steady state (Vdss) 0.18 l/kg. Body clearance (ClB) and renal clearance (ClR) were 0.12 l/h/kg and 0.03 l/h/kg, respectively. Approximately 28% of unchanged probenecid was excreted in urine. Plasma probenecid concentrations after i.v., i.m. and s.c. injections were 133, 37, and 31 micrograms/ml, respectively, at 15 min; 76, 36, and 34 micrograms/ml at 1 h; and 43, 23 and 34 micrograms/ml at 2 h. The average bioavailability of probenecid given by i.m. and s.c. injection was 46% and 34%, respectively. However, after 2 h, probenecid plasma concentrations remained higher when it was given subcutaneously than when it was given intramuscularly. Urine output was correlated positively (P less than 0.05) with kel and ClB. Urine pH increased significantly (P less than 0.01) for the first 2 h, and then steadily declined over the subsequent 6 h. The results suggested that probenecid in sheep was rapidly eliminated because it was rapidly excreted in the normal but alkaline urine. Subcutaneous administration of probenecid in animals may be a useful alternative to oral or i.v. administration.  相似文献

Conception rates in European fallow does (Dama dama dama) following intrauterine insemination with frozen-thawed semen from Mesopotamian fallow (Dama dama mesopotamica) and crossbred (Dama dama dama x Dama dama mesopotamica) bucks     

GE MYLREA  G. EVANS†  AW ENGLISH 《Australian veterinary journal》1991,68(9):294-295

Ninety eight parous fallow does received laparoscopic intrauterine insemination of frozen-thawed semen at one of 2 fixed intervals following oestrus synchronisation treatment. Semen was collected from a Mesopotamian (Dama dama mesopotamica) and a crossbred (F1) (Dama dama dama x Dama dama mesopotamica) fallow buck. Does were inseminated at either 56 or 66 hours after the removal of an intravaginal controlled internal drug releasing device. Eighty eight does received a single straw of frozen-thawed semen containing a total of 50 x 10(6) spermatozoa, while the remaining 10 received split straws containing 25 x 10(6) spermatozoa. Overall, the use of F1 semen containing 50 x 10(6) spermatozoa resulted in a 68% (17/25) conception rate compared with the Mesopotamian semen, which resulted in a 41% (26/63) conception rate. Conceptions were also achieved using 25 x 10(6) spermatozoa of either Mesopotamian or F1 semen (3/8 versus 2/2, respectively). Overall, the conception rate was higher for F1 than Mesopotamian semen (P less than 0.025) and there was a significant interaction with time of insemination (P less than 0.05); for F1 semen there was no difference in conception rate at the 2 insemination times, but for Mesopotamian semen conception was significantly higher (P less than 0.005) following insemination at 66 hours than at 56 hours.  相似文献

Pharmacokinetics of cefotaxime and probenecid in sheep with normal and reduced renal function     

V. H. GUERRINI  L.J. FILIPPICH  P. B. ENGLISH  G. R. CAO  D. W. A. BOURNE 《Journal of veterinary pharmacology and therapeutics》1984,7(4):283-291

The pharmacokinetics of cefotaxime and probenecid, given by intravenous injection, were determined in six Merino ewes which had been subjected to a 75% reduction in renal mass. These results were compared with results previously determined in sheep with normal renal function. In the sheep with reduced renal mass, the following significant changes in parameter values for cefotaxime were observed. The elimination rate constant (kel) decreased by 47%, the apparent volume of the central compartment (Vc) decreased by 59%, the steady state volume (Vss) decreased by 50%, and the total body clearance (ClB) decreased by 78%. The rate constant for distribution of drug into tissues (k12) increased 6.9 times, the rate constant for distribution out of tissues (k21) increased 3.7 times, and the area under the plasma concentration-time curve (AUC) increased by a factor of 4.9. The parameter values, determined in sheep with reduced renal mass, for probenecid plasma half-life, Vss and the rate constants k12, k21, and kel were not significantly different from the values obtained previously in sheep with normal renal mass. However, the rate constant for renal excretion of probenecid (ke), renal clearance (ClR), ClB and Vc decreased by 79, 90, 54 and 36%, respectively. The results indicate that reduced renal mass increased the plasma half-life for cefotaxime as well as increasing its diffusion into tissue. In the case of probenecid the overall distribution and elimination kinetics were not altered by reduced renal mass; however, the rate of urinary excretion of the drug was reduced.  相似文献
