“…Precipitation pattern but not precipitation amount interacted with infestation; the unimodal rainfall pattern was correlated with low infestation. A discrepancy in how abiotic factors correlate with either F. arisanus or its host B. dorsalis (De Villiers et al, 2015;Lane et al, 2018) might explain why biological control can be more efficient in some areas than in others. No interaction between temperature, precipitation, or rainfall pattern and F. caudatus parasitism was observed.…”

Biotic and abiotic factors affect herbivores and their natural enemies and understanding of their requirements may permit habitat modification enabling conservation biological control. Ceratitis cosyra Walker (Diptera: Tephritidae), an African-native fruit fly pest is mostly parasitized by the parasitoid wasp Fopius caudatus Sz epligeti (Hymenoptera: Braconidae). To assess F. caudatus habitat, the wasp parasitism levels and infestation of its fruit fly host were examined in Sarcocephalus latifolius (Smith) Bruce (Rubiaceae), a shrub of which the fruits are among the preferred hosts of C. cosyra and F. caudatus. Fruit-collection site descriptions, including plant species presence, were analysed in relation to the target insect abundances (emergence from target fruit). Ceratitis cosyra and F. caudatus emerged from all sites; nonetheless, their population levels were associated with both abiotic and biotic factors, of which some can be manipulated. Several factors, such as cultivation level, topography, and vegetation coverage, were correlated with F. caudatus parasitism. Ceratitis cosyra infestation level was correlated with factors such as density of S. latifolius, vegetation cover, cultivation practices, temperature, altitude, rainfall pattern, and stoniness. Proximity to other fruit fly host plants correlated with both pest abundance and F. caudatus parasitism level of the fruit fly. The findings that insects' interactions and abundance are influenced by habitat structure and that parasitism is positively related to natural habitat indicates the importance of maintaining natural habitats in closeness to cultivated areas with the aim of enhancing pest suppression by parasitoids. Further studies should attempt to identify how plant species composition in and around orchards could affect the management of tephritid fruit fly pests.

“…A second major component of our study is to document morphological and genetic changes associated with the current, ongoing northward invasion of B. dorsalis into Central China. Although well-documented in tropical and sub-tropical China (Wan, Nardi, Zhang, & Liu, 2011), B. dorsalis was historically absent from Central China because of climatic unsuitability (specifically cold stress (Stephens, Kriticos, & Leriche, 2007;De Villiers et al, 2016)).…”

Bactrocera dorsalis, the Oriental fruit fly, is one of the world's most destructive agricultural insect pests and a major impediment to international fresh commodity trade. The genetic structuring of the species across its entire geographic range has never been undertaken, because under a former taxonomy B. dorsalis was divided into four distinct taxonomic entities, each with their own, largely non‐overlapping, distributions. Based on the extensive sampling of six a priori groups from 63 locations, genetic and geometric morphometric datasets were generated to detect macrogeographic population structure, and to determine prior and current invasion pathways of this species. Weak population structure and high genetic diversity were detected among Asian populations. Invasive populations in Africa and Hawaii are inferred to be the result of separate, single invasions from South Asia, while South Asia is also the likely source of other Asian populations. The current northward invasion of B. dorsalis into Central China is the result of multiple, repeated dispersal events, most likely related to fruit trade. Results are discussed in the context of global quarantine, trade, and management of this pest. The recent expansion of the fly into temperate China, with very few associated genetic changes, clearly demonstrates the threat posed by this pest to ecologically similar areas in Europe and North America.

“…In 2006, a National Exotic Fruit Fly Action Plan was developed outlining trapping protocols for fruit fly detection at ports of entry and in fruit production areas (Barnes & Venter, 2006). These models were improved when De Villiers et al (2015) incorporated seasonal phenology as well as irrigation. When this plan was put in place three species were identified as high risk due to their presence on the African continent.…”

Developing a general management framework for monitoring and reporting biological invasions in agricultural contexts is crucial to assist in the planning and execution of intervention and control strategies. Here we make use of a diverse range of data sets for economically significant South African agricultural fruit fly pests to offer several potential intervention strategies and present a general management framework that unifies different but related fields of research (invasion science and pest management). We review the status of Tephritidae (Diptera) in South Africa with a strong focus on the highly invasive Bactrocera dorsalis (Hendel) and touch on the use of population genetics in pest or invasion management. Integrated modelling of landscape friction from population genetics is undertaken to test for any intrinsic resistance to pest movement across the landscape (e.g., natural or agricultural barriers). Based on the novel analyses presented here, clearly defined landscape management units can be allocated. Across South Africa, control and intervention strategies for managing both invasions of new Tephritidae and existing pest species can be unified into a common framework. Finally, we illustrate the concepts outlined above in a conceptual management decision tree for integrating pest management and invasion management simultaneously. Promoting awareness among growers and the public about fruit fly invasions and impacts is a priority to prevent future incursions of fruit flies, whereas managing Tephritidae as distinct landscape units should facilitate prevention of movement of emerging and existing pests.
