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 production 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 methods are available against bugs. In this study we have tried a cultural control method (mowing of groundcover) 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...

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.

Pilot field studies on insect pathogenic fungi to control mirid pests of apples in Norway Organic Eprints
Jaastad, G.; Klingen, I.; Westrum, K.; Hovland, B..
In a pilot field study conducted in an apple orchard in Hardanger (Western Norway) in two succesive years both Beauveria bassiana and Metarhizium anisopliae were applied to apple trees just after hatching of mirid nymphs in spring. Both predatory, omnivorous and principally plant-pathogenic species of mirids were collected, and all groups of species were infected by B. bassiana or M. ansiopliae in treated plots. B. bassiana and M. anisopliae were also found on some individuals in non treated control plots the second year. M. anisopliae was more predominant in 2006, B. bassiana in 2007. Mirids were also observed for natural occurrence of parasitoids, and parasitoids were found both years.

Kaolin as a possible treatment against lepidopteran larvae and mites in organic fruit production Organic Eprints
Jaastad, G.; Røen, D.; Helgheim, Å-M.; Hovland, B.; Opedal, O..
Few control methods are available in Norwegian organic fruit production that can prevent damage by early and late larvae. Also phytophagous mites are difficult to control without harming the beneficial mites. Processed kaolin function by coating trees and thus creating a physical barrier to infestation, impeding movement, feeding and egg-laying. Kaolin may reduce feeding and movement of over-wintering tortricide larvae and other larvae that hatch early in spring and have a repellent effect against egg-laying tortricide females in summer. Kaolin may also have a control effect against mites as it clings to the body and reduce feeding. Trials with kaolin were conducted in 2003, 2004 and 2005 in plum and apple orchards. Results show that kaolin reduces...
