“…The introduction of P. boerneri into Africa is believed to have been via pine scions imported into Zimbabwe and Kenya from Australia in 1968 (Odera, 1974), and genetic analysis by Blackman et al (1995) has confirmed an Australian link. Since then, P. boer neri has spread to a further six countries in eastern and southern Africa, mostly by the movement of infested nursery stock (Zwolinski, 1989), and also infests Pinus plantations in Brazil (Oliveira et al, 2008). Adelgids are related closely to aphids and occur only on conifers.…”

“…In the early stages of infestation, or on lightly infested trees, colonies of the adelgid occur under scales of the bud base, on shoots at the base of a needle fascicle, or on needles inside a fascicle (Zwolinski, 1989). Later, the infestation spreads to the new growth and down to the bark of thicker branches and the stem.…”

Since the publication of the first edition of this book in 2001, there have been several significant developments in forestry and forest entomology in the tropics that warranted inclusion in a second edition. One is the emergence of new pest species associated either with the expansion of plantation forestry into new regions or marginal areas, or a gradual adaptation by indigenous species to exotic hosts or the rapid spread of new invasives. The South American carpenterworm, Chilecomadia valdiviana, in Chile, and the South African goat moth, Coryphodema tristis, are examples of emerging indigenous pests associated with the establishment and expansion of exotic Eucalyptus spp. plantations in these countries. The blue gum chalcid, Leptocybe invasa, and the erythrina gall wasp, Quadrastichus erythrinae, are recent examples of the rapid worldwide spread of an invasive insect, similar to that which occurred for the leucaena psyllid, Heteropsylla cubana, in the 1980s and 1990s. The biology, ecology and impact of these, and many additional pest species, are discussed in an expanded Chapter 5.Another development has been the growing awareness of the 'true' global impact of forest invasive species as losses have been better quantified. Damage worldwide has been estimated at several billion US dollars per year, even without taking into account the loss of non-market value, which may well exceed that figure. This has prompted a range of international responses, including the formation of networks and surveillance programmes to provide early warning of incursions of forest invasives and the development of international standards for phytosanitary measures, such as that for wood packaging material, as discussed in Chapter 9. The global increase in self-help schemes such as plant clinics and field schools is also discussed. A range of new technologies has enhanced the accuracy and efficiency of forest health surveys over the past decade. These include the use of geographic information system-global positioning system interface tools and handheld computers to assist navigation and data collection in the field, and the application of digital, remotely sensed imagery to detect and classify damaged forest canopies. There have also been significant advances in the use of semiochemicals, including pheromones, for the detection and monitoring of forest pests and for controlling pest populations by means of mass trapping, lure and kill, lure and infect and mating disruption.One of the fundamental principles underlying this book is that the prevention of problems is far better than attempts at cures. The book is not in any way designed to be a manual of pest management. Instead, it presents concepts and examples of tropical forest viii Preface insects, their ecology, impact and control approaches where appropriate, and we hope that individual readers will make the connection between the generalities in the book and their own situation, socio-economic position and appropriate technologies. Some situations or examples have been revisited...

Summary1 The spatial and temporal distribution of pine woolly aphids, Pineus boerneri (Homoptera: Adelgidae) a pest of exotic pine trees in Malawi, was investigated in 5‐year‐old Pinus kesiya trees.2 Pineus boerneri was generally found to settle and reproduce on the outer shoot‐end sections of young P. kesiya trees. There was no evidence of preference for any particular levels of the tree canopy.3 The study suggests that the biological performance and, by implication, the pest status of P. boerneri in young P. kesiya trees can be influenced by external factors, particularly by the within‐tree and seasonal fluctuations in the level of nitrogen in the host trees, total rainfall and canopy structure.4 These findings are discussed in relation to possible management and control of P. boerneri in Malawi.
