Effects of Azadirachtin and the natural pesticides Spinosad and Avermectin on the leafminer Liriomyza sativae (Diptera: Agromyzidae) and its parasitoids on tomatoes under protected cultivation in the humid tropics Von der Naturwissenschaftlichen Fakult?t der Universit t Hannover zur Erlangung des Grades Doktor der Gartenbauwissenschaften - Dr. rer. hort. - genehmigte Dissertation von M.Sc Mohammad Babul Hossain geboren am 05.12.1964 in Bagerhat, Bangladeah 2005Referent: Professor Dr. Hans-Michael Poehling Korreferent: Dr. Rainer Meyh?fer Tag der Promotion: 08.02.2006 Sumary ISummary Among the economic important Liriomyza spp., Liriomyza sativae causes substantial damage to tomatoes for instance infestation strongly reduces the photosynthetic activities resulting in high yield losses. The studies were ficonducted to investigate the effects of biopesticides (NeemAzal -U and fiNeemAzal -T/S) and biorational pesticides (Spinosad and Abamectin) on L. sativae and its two parasitoids, Opius (Opiothorax) chromatomyiae and Neochrysocharis formosa both under laboratory and greenhouse conditions. fiAll tested NeemAzal -U (17% Azadirachtin) concentrations applied as solutions to the substrate of potted tomatoes had very low effects on oviposition and egg hatch.
