CiteScore: ℹ CiteScore: CiteScore measures the average citations received per document published in this title. CiteScore values are based on citation counts in a given year (e.g. ) to documents published in three previous calendar years (e.g. – 14), divided by the number of documents in these three previous years (e.g. – 14). The cost of developing and conducting a biological control program varies with the target weed and the strategy selected. On average, a biological control program will cost about $4 million. But every dollar spent in development returns at least $50 in benefit. Biological control of weeds will not eliminate the need to use chemical herbicides.
This book follows on from a previous volume 'Biological Control Programmes against Insects and Weeds in Canada, ' published in It includes chapters written by well known scientists involved in work on biological control between and The work reported provides models that will be applicable in many other countries. Biological control of weeds has been practised for over years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many by:

In this comprehensive textbook, with 8 sect. and 24 chapt., written principally by members of the Dept of Biological Control, Univ. Calif., Berkeley and Riverside, reference is made to fungus diseases of insects () and to the possible use of plant pathogenic fungi in the control of weeds ().Cited by: Biological Control of Weeds.
by Professor Alan Watson Department of Plant Science. Introduction. Biological control of weeds is the deliberate use of natural enemies to reduce the density of a purticular weed to a tolerable level The objective of biological weed control is not eradication but simply the reduction of the weed population to an economically low level In fact for biological.
Biological control attempts primarily to reduce weed population to a density that will not cause economic damage. By nature biological control organisms are selective in their food preferences and cannot provide broadspectrum control that is achievable with other methods.

Farnham Royal, Eng., Commonwealth Agricultural Bureaux . ▪ Abstract Classical biological control, i.e. the introduction and release of exotic insects, mites, or pathogens to give permanent control, is the predominant method in weed biocontrol.
Inundative releases of predators and integrated pest management are less widely used.

Similarly, insects frequently have been instruments of biological control for other insects or invasive weeds (see Chapter 17). Thomson and Hoffman () reported that biological control of insect pests was enhanced when vinyards were surrounded by natural remnant forest or planted woody vegetation, compared to no woody vegetation.
Although prerelease studies in general, and host range testing in particular, only recently have begun to be part of biological control programs against insect pests, they have a long-standing tradition in the classical biological control of weeds.

and B. McGugan and H. Coppel. THE BIOLOGICAL CONTROL OF WEEDS BOOK November TE WHAKAPAU TARU – ISBN 0 – – – 3 WHAT IS BIOLOGICAL CONTROL OF WEEDS. What is a weed. A weed is a plant that grows so well it becomes a nuisance, for example by displacing other more desirable plants, reducing primary production, or our enjoyment of the environment.
Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors.
Biological control agents of plant diseases are most often referred to as antagonists. Biological control agents of weeds include seed predators, herbivores and plant pathogens.
As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. The Future of Biological Control of Weeds with Insects: No More ‘Paranoia’, No More ‘Honeymoon’ R.

S. Kelleher.Introduction The recorded history of biological control may be considered as dating from Egyptian records of 4, years ago, where domestic cats were depicted as useful in rodent control.
Insect Predation was recognized at an early date, but the significance of entomophagy and exploitation was lost except for a few early human populations in Asia where a sophisticated agriculture had developed.
