| The Kenya Agricultural Research Institute (KARI) imported 12 800 curculionid weevils (Neochetina spp.) from Benin, Uganda, South Africa and Australia for biological control of water hyacinth between 1993 and1998. In 1996, KARI’s rearing and quarantine facility at the National Agricultural Research Centre, Muguga, provided initial “breeding stock” to another rearing facility at the National Fibre Research Centre, Kibos, near Lake Victoria. To date, 36 500 weevils and 42 000 weevil eggs have been produced from Kibos. About 2000 weevils were produced each month from plants grown in plastic basins, galvanized corrugated iron sheet tanks and a polypropylene rearing pool. Between January 1997 and August 1998, KARI released 36 250 Neochetina weevils at 27 sites... |

| The inventory of the alien Acari of Europe includes 96 species alien to Europe and 5 cryptogenic species. Among the alien species, 87 are mites and 9 tick species. Besides ticks which are obligate ectoparasites, 14 mite species belong to the parasitic/predator regime. Among these species, some invaded Europe with rodents (8 spp.) and others are parasitic to birds (2 spp). Th e remaining 77 mite species are all phytophagous and among these 40% belong to the Eriophyidae (37 spp.) and 29% to the Tetranychidae (27 spp.) families. Th ese two families include the most signifi cant agricultural pest. Th e rate of introductions has exponentially increased within the 20th century, the amplifi cation of plant trade and agricultural commodities movements being the... |

| Candidate insect pathogens were fed at various levels to honey bees (Apis mellifera) either in small cages or in observation hives. The pathogens tested included two polyhedrosis viruses, a granulosis virus, a commercial preparation of Bacillus thuringiensis var. thuringiensis, spores, crystals, and the exotoxin of this variety, plus the crystals of varieties alesti and sotto. No mortality was recorded as a result of treatment with any of these pathogens except with the highest level of the exotoxin of B. thuringiensis. |

| Soilless cultures were originally developed to control soilborne diseases. Soilless cultures provide several advantages for growers such as greater production of crops, reduced energy consumption, better control of growth and independence of soil quality. However, diseases specific to hydroponics have been reported. For instance, zoospore-producing microorganisms such as Pythium and Phytophthora spp. are particularly well adapted to aquatic environments. Their growth in soilless substrates is favoured by the recirculation of the nutrient solution. These pathogenic microorganisms are usually controlled by disinfection methods but such methods are only effective as a preventive measure. Contrary to biofiltration, active treatments such as UV, heat and... |
