Teaching Weed
Biocontrol
This
excellent book* was produced following many requests for copies of the lecture notes
handed out to participants of the International Courses in the Biological Control of
Tropical Weeds run by CTPM (the Cooperative Research Centre for Tropical Pest Management,
Queensland, Australia). The CTPM course was designed for scientists and managers involved
in the regulation, management or implementation of the biological control of weeds but
with limited experience in the area. The main aims of the courses are to give participants
a balanced understanding of the theory of weed biological control and practical exposure
to the procedures followed in a weed biological control programme.
The book is a
modified and extended version of the lecture notes, and provides an overview of biological
control of weeds and how to go about it. It includes useful reference lists for each
topic. It begins by considering how to define and measure success and failure in
biological control of weeds. A history of the biological control of weeds is given,
followed by introductions to weed science and population ecology in the context of the
biological control of weeds. The importance of taxonomy in biological control studies is
also dealt with. The stages of a project, procedures, methods and techniques, are covered
in detail, from the beginning of a project to evaluating its impact. Some sections
describe methodology and others case studies. Topics covered include: exploration for
biological control agents, and prioritzing those found; climate matching using the CLIMEX
program; protocols and quarantine procedures for importation and release of agents;
compiling a plant list for testing the host range of potential biological control agents;
plant (including aquatic plant) propagation and culture for host range testing; methods
for host range testing, and decision-making based on test results; mass rearing,
distribution and establishment of insect agents; participatory approaches to biological
control of weed programmes; measuring the impact of biological control agents on weeds,
and cost-benefit analysis for biological control projects. There are sections dealing with
plant pathogens as classical biological control agents, bioherbicides, and the mass
production of fungi for biopesticides. A set of 38 slides providing a precis of weed
biological control, reproduced in the book as colour prints, are also available.
Although this
book deals principally with weeds and biological control in the Asia-Pacific region, it
originated from training material and, as a well-organized and clearly written work, will
have universal appeal in this context.

Insect Biocontrol in Southeast Asia
This book*
summarizes current knowledge on natural enemies (principally the parasitoids) of 16 major
exotic insect pests of Southeast Asia, and estimates the prospects for their biological
control. The aim of the book is to facilitate, for the countries of the region, the
selection of promising priority insect pest targets, and to provide donor agencies with a
readily accessible overview of the region's major exotic pest problems and an evaluation,
where possible, of prospects for their amelioration using biological control.
Of the 16
pests dealt with, 13 have had biological control programmes against them in one or more
regions of the world, and substantial or partial success has been achieved, in one or more
countries, for eight of these. Evidence is put forward to support the argument that there
are good-to-excellent prospects for reducing damage, at least in some parts of Southeast
Asia, from Leucinodes orbonalis, Nezara viridula, Ophiomyia phaseoli and Planococcus
citri. Evidence is also provided to support the argument that there will prove to be
valuable natural enemies for Agrius convolvuli, Anomis flava, Aphis craccivora, Aphis
gossypii, Diaphorina citri, Dysmicoccus brevipes, Hypothenemus hampei, Phyllocnistis
citrella and Trichoplusia ni. It is suggested that there is little prospect for
the classical biological control of Dysdercus cingulatus, while too little is known
about Deanolis sublimbalis. Propects for control of Cosmopolites sordidus are
described as unclear, but its lack of pest status in Myanmar is noted.

Ethical Issues
This special
journal issue* includes ten articles that explore the consequences of different strategies
of biological control, their effectiveness and their ethical implications. In his opening
article, Lockwood summarizes the issues dealt with, and outlines the major ethical
questions raised. Issues of safety are dealt with first. R. G. Van Driesche & M.
Hoddle consider how to conduct and interpret host range testing to safeguard non-target
organisms. J. J. Duan & R. H. Messing explore the complexity of assessing
environmental impact, using the biological control of fruit flies in Hawaii as a case
study. R. R. James explores ethical issues in the context of transgenic insect-resistant
trees. J. L. Ricard & T. J. Ricard present arguments for and against the view that
fungal agents in fruit production present little risk to the environment. Next, B. H.
Jennings describes political , economic and cultural obstacles to alternative pest
management strategies. R. Wilkinson & G. Fitzgerald discuss the distribution of the
decision-making powers in the context of the biological control of rabbits in New Zealand.
J. W. Bentley & R. J. O'Neill explore issues relating to the non-industrial world,
where maintaining agricultural food production is essential for the human population, and
the argument is one of chemicals vs biologicals. P. M. Rosset discusses the effects of the
Cuban agricultural and economic crisis [also see Biorational, this issue], and argues that
the apparent ability of Cuba to overcome a food crisis without significant use of
pesticides helps to refute the commonly used argument that pesticides are necessary to
`feed the hungry'. Finally, M. A. Altieri, P. M. Rosset & C. I. Nicholls challenge the
view of biological control as a technical substitute for agrochemicals, and also deal with
the moral issue of biological control technology as a net transfer of resources from poor
to rich nations with little/no payment.

A number of
national organizations already have seasoned websites with a lot of useful information and
services for biocontrol researchers and practitioners worldwide. One such is the
EMBRAPA/Base de Dados Tropical site at
http://www.bdt.org.br/bdt/biocontrol/
This
biological control information system has a number of databases, including an increasingly
important one on `Who is who in risk analysis of the use of biocontrol agents' [see BNI
18(2)]. To add your name to this list or get further information, contact Email: ainfo@cnpma.embrapa.br. The site also has
information on the current status of legislation relating to biocontrol in South America,
and it also hosts the email biocontrol discussion list, Biocontrol-L. For readers not
familiar with this list, you can subscribe to this list [send the message "Subscribe
