IPM for Home Gardeners
Pest problems in the garden usually arise either because the plants chosen are poorly adapted to the site (and hence under stress), or because inadequate attention is being paid to maintaining plant health through proper care and maintenance. Following the principles of IPM outlined in the guide below can help prevent pest outbreaks in the garden and benefit a surprising diversity of wildlife - both large and small. The larva on the right, for example, eventually turns into a beautiful Black Swallowtail butterfly - an addition to the garden that is well worth the sacrifice of a few of your dill plants, which will usually re-grow anyway.
An important component of IPM is the suite of naturally occurring biological control agents (predators and parasites) that can help keep potential pests under control. Some of these beneficial insects are illustrated in the guide in the second link below.
