Biological Control
KLAMATH WEED (= ST. JOHN'S WORT) Hypericum perforatum L. – Hypericaceae Dr. E. Fred Legner, University of California Retrieved from: http://faculty.ucr.edu/~legneref/biotact/ch-66.htm This weed is of European origin, and was first reported as a pest in northern California near the Klamath River. It increased and spread rapidly and by 1944 had occupied over two million acres of rangeland in thirty counties of California. Not only were food forage plants greatly reduced but cattle and sheep lost weight when eating the weed because of its toxic effect, sensitizing them to sunlight. This resulted in such a great decrease in land values that it became almost impossible for ranchers to borrow money for development (DeBach 1974). Chemical herbicides were available but not practical because of cost and the inaccessibility of most of the infested land. Dr. Harry S. Smith, head of biological control work in California, proposed the importation of insects that attacked the weed as early as 1922, but the thought of deliberately introducing a plant feeding insect was not acceptable at that time. At the same time, in Australia phytophagous insects to control Klamath weed were being introduced from England and Europe beginning in 1929, and Dr. Smith in California followed the progress there with great interest through correspondence with Dr. A. J. Nicholson, Chief Entomologist for the Commonwealth Scientific and Industrial Research Organization (CSIRO). Authorization was finally obtained in 1944 to import three species of beetles that showed promise against the weed in Australia. It was not possible then to consider importations from Europe because of World War II, but rather simple to bring material from Australia through the cooperation of the United States Army Transport Command.

An Alternative Perspective for the Theory of Biological Control
insects Perspective An Alternative Perspective for the Theory of Biological Control Nicholas J. Mills Department of Environmental Science, Policy and Management, University of California, Berkeley, CA 94720-3114, USA; [email protected]; Tel.: +1-510-642-1711 Received: 12 September 2018; Accepted: 29 September 2018; Published: 2 October 2018 Abstract: Importation biological control represents the planned introduction of a specialist natural enemy from the region of origin of an invasive pest or weed. For this study, the author considered why attempts to develop a predictive theory for biological control have been misguided and what future directions might be more promising and effective. Despite considerable interest in the theory of consumer–resource population dynamics, such theory has contributed little to improvements in the success of biological control due to a focus on persistence and equilibrium dynamics rather than establishment and impact. A broader consideration of invasion biology in addition to population ecology offers new opportunities for a more inclusive theory of biological control that incorporates the demographic and genetic processes that more speciﬁcally address the establishment and impact of introduced natural enemies. The importance of propagule size and genetic variance for successful establishment, and of contributions to host population growth, relative population growth rates, interaction strength, and coevolution for suppression of host abundance are discussed as promising future directions for a theory of biological control. Keywords: pest; weed; importation; establishment; impact; demography; genetics 1. Introduction Biological control is an ecosystem service in which a pest or weed is effectively controlled through interactions with its natural enemies, and in many cases the natural enemies are insects [1].

Species Pairs for the Biological Control of Weeds: Advantageous Or Unnecessary?
Species pairs for the biological control of weeds: advantageous or unnecessary? C.A.R. Jackson and J.H. Myers Summary Two or more species of insects in the same genera have been introduced in some weed biological control programs, either by accident or on purpose, to increase the climatic range distribution of the agents. If the species are ecological equivalents, the introduction of both species will be unnecessary and may be detrimental if competition reduces their overall impacts. If however the species vary in the type of attack or their distributions, the introduction of congeners can be advantageous. In this paper, we review the following cases of species pair releases in the biological control of weeds in North America: the beetles Chrysolina quadrigemina (Suffrian) and Chrysolina hyperici (Forster) for St. Johnswort (Hypericum perforatum L.); the gallflies Urophora affinis Frfld. and Urophora quadrifasciata (Meig.) for knapweed (Centaurea) species; the weevils Neochetina bruchi Hustache and Neochetina eichhorniae Warner for water hyacinth [Eichhornia crassipes (Mart.) Solms] and the beetles Galerucella pusilla Duftschmidt and Galerucella calmariensis L. for purple loosestrife (Lythrum salicaria L.). In the cases of Chrysolina and Galerucella, the species pairs appear to be complementary for control of the target weeds, with each species providing good control in slightly different habitats and coexisting at some sites. With the Urophora gallflies, one species is more ef- fective than the other, but overall, seed reduction is greater when both agents are present in combi- nation (although this seed reduction is insufficient for a reduction of the target weed). In the case of the Neochetina beetles, a difference in the ability of the two species to kill plants was apparent, but whether they differed in habitat preferences was less clear.
