Última Control methods against bugs (Hemiptera; Heteroptera) in organic apple and pear production Organic Eprints Jaastad, G.; Trandem, N.; Hovland, B.; Opedal, O.; Mogan, S.; Røen, D.; Sørum, O.; Bjotveit, E.. True bugs (Hemiptera; Heteroptera) are important pests in fruit production in Norway. In organic fruit pro-duction they may damage up to 40% of the crop. Several of the Heteropteran species attacking apple and pear are polyphagous, with many other hostplants than pome fruit. In organic production few control meth-ods are available against bugs. In this study we have tried a cultural control method (mowing of ground-cover) as well as spray applications of various biological insecticides against bugs. Spray application of azadirachtin (NeemAzal), rape oil and garlic extract (Ecoguard) were tested. Results indicate that the effect of mowing groundcover inside the orchard is variable and small. Applying NeemAzal reduced the number of bugs and damage. Oil and... Tipo: Conference paper, poster, etc. Palavras-chave: Crop health; Quality; Protection Fruit and berries. Ano: 2006 URL: http://orgprints.org/8817/1/ecofruit_12th_10.pdf A survey of natural parasitism of mirid bugs by parasitoids on apples and pears in Norway Organic Eprints Jaastad, G.; Trandem, N.; Hovland, B.; Djønne, R. T.. Mirid bugs are important pests in both integrated and organic fruit production. In a survey in 2006 the proportion of mirids parasitized by parasitoids was investigated in 18 Norwegian orchards. More than 50 beating samples were collected from apple and pear orchards under integrated and organic management in different areas of Norway. About 30% of nymphs of the most abundant mirid bug species, Lygocoris pabulinus, Ortholylus marginalis and Psallus ambiguus, were parasitized. Important factors for enhancing biological control in organic fruit production are discussed. Tipo: Conference paper, poster, etc. Palavras-chave: Crop health; Quality; Protection Fruit and berries.
