But such predators as adults commonly migrate between nearby plants to feed and lay eggs and can be important in the biological control of pests on those other hosts, such as aphids. The extensive Eucalyptus plantations created in many countries have so far suffered relatively little from attack by insects or diseases, and even such damage as has been caused has apparently been generally insignificant. But it is evident that the establishment of pure Eucalyptus plantations on a large scale creates a risk of possible serious attacks that could result in a dangerous setback to the economic use of these quick-yielding species. Although these genera are present in nearly all areas, they seem to be less prevalent in low sandy or permanently cultivated lands. Do not wait until pest infestations or damage symptoms are severe to monitor trees because cultural controls such as providing sufficient soil moisture (generally by irrigation) and avoiding any nitrogen application to host tree's root zone are primarily preventive and must be practiced early.
