Field experiments to evaluate four different coloured sticky traps for monitoring beneficial insects were conducted on Braeburn apple blocks in four commercial orchards situated in the Motueka region Traps used were white yellow and blue Corflute sheets and a clear Mylar sheet all coated on one side with adhesive (Tactrap) The sticky traps were deployed between 27 February and 24 March 2006 Each colour sticky trap was hung vertically from a branch within the tree and traps were replaced and rerandomised two times during the trapping period Beneficial insects monitored included Aphelinus mali Platygaster demades Anagrus sp Stethorus bifidus and Encarsia spp Results indicated that yellow was the best trap colour for catching A mali Stethorus and Encarsia and a clear trap was best for Anagrus sp Trap colour did not have a significant impact on the catch of P demades

AbstractOvex, tetradifon, and chlorbenside which are largely innocuous, and parathion which is more harmful, to beneficial insects and predaceous mites, have been used in apple orchards in Nova Scotia to control outbreaks of phytophagous mites. Dicofol is used at present but it is toxic to predaceous mites. Animert V-101 is effective against Panonychus ulmi (Koch) but is ineffective on most beneficial species. Dicofol and Animert V-101 initially reduced a high population of P. ulmi but were equally ineffective on predaceous insects. The latter chemical was innocuous to Typhlodromus pyri Scheuten and Vasates schlechtendali (Nal.) but gave partial control of P. ulmi. A similar high population of P. ulmi was reduced to a low level on a comparative untreated plot where a high number of predators was present. This reduction was evident 1 month later than on the treated plots. The overwintering numbers of P. ulmi in 1966 were below a commercially tolerable level on the three plots.
