Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Haukeland Solveig and Sundbye Anette The slug parasitic nematode Phasmarhabditis hermaphrodita is commercially available for slug control in many European countries and is mainly used in home gardens against the grey field slug Deroceras reticulatum. In some European countries it is used against the invasive slug pest Arion lusitanicus. The standard application method for using P. hermaphrodita is by surface application at a rate of 300 000 nematodes per square meter. Several studies have shown that A. lusitanicus individuals above 1 gram are not affected by P. hermaphrodita and field experiments indicate that this standard application method does not significantly reduce slug populations. Traditional molluscicides include an attractant, often wheat based packed around an active chemical ingredient. A slug baiting method, using P. hermaphrodita as the active ingredient, might be a better approach for biological control of slugs rather than surface application. We therefore decided to test the effect of P. hermaphrodita treated baits in laboratory and field studies. Laboratory experiments suggest this approach as promising, also against slugs above 1 gram. Results from ongoing field experiments will be presented and discussed.

Box 3005 Morogoro, Tanzania. Yonna Kalinga, kalingaye@yahoo.co.uk, Maulid Mwatawala, mwatawala@yahoo.com and Amon Maerere, maerere@yahoo.co.uk Among the most important insect pests in fruit production in Tanzania are fruit flies (Diptera: Tephritidae) these include Bactrocera spp., Ceratitis spp. and Dacus spp. that can significantly reduce yield and fruit quality. Management of fruit flies include cultural control measures such as collecting and destroying infected host fruits, regulatory control (quarantine) and the use of insecticide baits. The best approach for control of fruit flies is to develop an IPM system that include several strategies to reduce the build up of damaging pest populations. Biological control agents such as entomopathogenic nematodes (EPN) are potential candidates within such a system. Naturally occurring EPN isolates in the genera Steinernema and Heterorhabditis have been isolated from a fruit growing area in the Morogoro region in Tanzania. Selected EPN isolates have been tested against larval and pupal stages of three important fruit fly species, Bactrocera invadence, B. cucurbitae and Dacus bivittatus. Results are promising and show that several isolates caused 70% to 90% mortality of larvae for all three fruit fly species. Laboratory studies on the ecological characteristics of selected EPN were also conducted using Galleria mellonella as host.
