“…Here again, the actual introduction was considered successful but not effective, as C. synchophanta failed to control its target (Munroe 1971). Subsequent work has shown that C. concinnata, likely introduced to Canada during these early Tothill releases, is one of the main causes for collapse of browntail moth populations across eastern North America (Elkinton and Boettner 2012). The initiatives of Hewitt and Tothill greatly accelerated biological control in Canada, launching programmes against at least 12 targets between 1925and 1940 (Fig.…”

Abstract-Biological control has been an important tactic in the management of Canadian forests for over a century, but one that has had varied success. Here, we review the history of biological control programmes using vertebrate and invertebrate parasitoids and predators against insects in Canadian forests. Since roughly 1882, 41 insect species have been the target of biological control, with approximately equal numbers of both native and non-native species targeted. A total of 161 species of biological control agents have been released in Canadian forests, spanning most major orders of insects, as well as mites and mammals. Biological control has resulted in the successful suppression of nine pest species, and aided in the control of an additional six species. In this review, we outline the chronological history of major projects across Canadian forests, focussing on those that have had significant influence for the development of biological control. The historical data clearly illustrate a rise and fall in the use of biological control as a tactic for managing forest pests, from its dominance in the 1940s and 1950s to its current low level. The strategic implementation of these biological control programmes, their degree of success, and the challenges faced are discussed, along with the discipline's shifting relationship to basic science and the environmental viewpoints surrounding its use.

“…An example of this can be seen with C. concinnata. Evidence from the North American use of C. concinnata as an introduced biocontrol agent for gypsy and brown-tail moths suggests that this species also has a very wide host range (Strazanac et al 2001;Elkinton & Boettner 2012), and that it is generally ineffective at preventing the spread of the two main target species because of low parasitism levels. This species was also detected at very low levels in UK OPM, but whether these were accidental parasitism events caused by adult females misinterpreting oviposition cues or the first steps in the host range expansion of the UK race of C. concinnata is unclear.…”

Determining the host-parasitoid interactions and parasitism rates for invasive species entering novel environments is an important first step in assessing potential routes for biocontrol and integrated pest management. Conventional insect rearing techniques followed by taxonomic identification are widely used to obtain such data, but this can be time consuming and prone to biases. Here we present a Next Generation Sequencing approach for use in ecological studies which allows for individual level metadata tracking of large numbers of invertebrate samples through the use of hierarchically organised molecular identification tags. We demonstrate its utility using a sample data set examining both species identity and levels of parasitism in late larval stages of the Oak Processionary Moth (Thaumetopoea processionea -Linn. 1758), an invasive species recently established in the UK. Overall we find that there are two main species exploiting the late larval stages of Oak Processionary Moth in the UK with the main parasitoid (Carcelia iliaca -Ratzeburg, 1840) parasitising 45.7% of caterpillars, while a rare secondary parasitoid (Compsilura conccinata -Meigen, 1824) was also detected in 0.4% of caterpillars. Using this approach on all life stages of the Oak Processionary Moth may demonstrate additional parasitoid diversity. We discuss the wider potential of nested tagging DNAmetabarcoding for constructing large, highly-resolved species interaction networks.

“…But there are many exceptions. For example, the tachinid parasitoid Compsilura concinnata, introduced in North America against the gypsy moth, has more than 200 known hosts (Elkinton and Boettner 2012). On the other hand, successful predators such as the coccinellids Hyperaspis pantherina and Rodolia cardinalis, released against the orthezia scale in St Helena and against the cottony cushion scale in the Galapagos, respectively, or the beetle Rhizophagus grandis, released against the great spruce bark beetle (Dendroctonus micans) in Europe, are specific (Grégoire et al 1992;Van Driesche et al 2010;Cock et al 2015).…”

Classical biological control of insect pests of trees: facts and figures

et al. 2017

View full text Add to dashboard Cite

Classical biological control (CBC) is the introduction of a natural enemy of exotic origin to control a pest, usually also exotic, aiming at permanent control of the pest. CBC has been carried out widely over a variety of target organisms, but most commonly against insects, using parasitoids and predators and, occasionally, pathogens. Until 2010, 6158 introductions of parasitoids and predators were made against 588 insect pests, leading to the control of 172 pests. About 55% of these introductions were made against pests of woody plants. Establishment rates of natural enemies and success rates were higher in CBC projects targeting pests of woody plants than other pests. This review aims to answer the questions most commonly asked regarding CBC against insect pests, with particular emphasis on tree pests. The topics covered include, among others: variations in rates of successes among different systems, different target insect groups and different agents; temporal trends in CBC practices and successes; economic and environmental benefits; risks and ways to mitigate the risks; CBC against native pests; accidental successes through the adoption of the invasive pests by native natural enemies or accidentally introduced agents; and prospects and constraints for the practice of CBC in the future. Questions are answered based on the analysis of two databases, the BIOCAT2010 database of introductions of insect biological control agents for the CBC of insect pests, and a database of introductions of entomopathogens against insect pests.
