Biological control methods of pest insects in oilseed rape

摘要: Parasitoids, predators, insect pathogenic fungi, nematodes and microsporidia have all shown promise in the biological suppression of key target pest, pollen beetle Meligethes aeneus rapeseed, as well control other rapeseed pests. Under favourable conditions beetles are locally temporarily already under efficient natural by one or several these agents, but overall remains number pest Finland, elsewhere Europe. Conservation to enhance appears most feasible approach solve problem. Field simulation data used demonstrate how a simple change tillage practice may be enough obtain beetle. Several options are, will available, subject successful registration microbial products based on fungi Metarhizium anisopliae Beauveria bassiana, nematode Steinernema feltiae. Strategies methods applying agents been developed facilitate either inundative treatments, ecosystem restoration (re-)establish presence agricultural fields. Critical components identified for maximising within functioning IPM system.
