Integrated pest management
An environmentally friendly alternative to pesticides is integrated pest management (IPM), which is usually available to home gardeners only by mail order. Certain insects are mass bred for their natural predatory habits and then released so they can seek out and attack their target prey. Some of the beneficial predators include predatory mites and lacewing.
Phytoseiulus persimilis is a predatory mite used to control two-spotted mites (or spider mites). These mites suck the sap from hop and rose leaves, causing them to mottle, yellow and die.
The Australian pear-shaped mite [Typhlodromips montdorensis) preys on most thrip larvae. Adult thrips create curling, deformed leaves or leave silvery-brown damage, deform fruit and leave pale feeding damage in flowers. This mite can be used for herbs that are susceptible to thrips, such as thyme and rosemary.
Green lacewing is employed to target thrips, mealybugs, greenhouse whitefly, small caterpillars and two-spotted mites and moth eggs.
