Impact of interspecific interactions among parasitoids on inoculative biological control of leafminers attacking chrysanthemum
… natural enemies occur within field grown crops at varying densities dependent upon a variety of other biotic and abiotic parameters. This natural control often does not provide adequate suppression, which results in the application of other remedial pest management solutions including …
