    Selecting for Tolerance Against Pathogens and Herbivores to Enhance Success of Reintroduction and Translocation

    Essay Selecting for Tolerance against Pathogens and Herbivores to Enhance Success of Reintroduction and Translocation MATTHEW D. VENESKY,∗† JOSEPH R. MENDELSON III,‡§ BRITTANY F. SEARS,∗ PETER STILING,∗ AND JASON R. ROHR∗ ∗Department of Integrative Biology, The University of South Florida, 4202 East Fowler Avenue, SCA 110, Tampa, FL 33620, U.S.A. ‡Zoo Atlanta, 800 Cherokee Avenue SE, Atlanta, GA 30315, U.S.A. §Georgia Institute of Technology, School of Biology, 301 Ferst Drive, Atlanta, GA 30332, U.S.A. Abstract: Some species have insufficient defenses against climate change, emerging infectious diseases, and non-native species because they have not been exposed to these factors over their evolutionary history, and this can decrease their likelihood of persistence. Captive breeding programs are sometimes used to reintroduce individuals back into the wild; however, successful captive breeding and reintroduction can be difficult because species or populations often cannot coexist with non-native pathogens and herbivores without artificial selection. In captive breeding programs, breeders can select for host defenses that prevent or reduce pathogen or herbivore burden (i.e., resistance) or traits that limit the effects of parasitism or herbivory on host fitness (i.e., tolerance). We propose that selection for host tolerance may enhance the success of reintroduction or translocation because tolerant hosts generally have neutral effects on introduced pathogens and herbivores. The release of resistant hosts would have detrimental effects on their natural enemies, promoting rapid evolution to circumvent the host resistance that may reduce the long-term probability of persistence of the reintroduced or translocated species. We examined 2 case studies, one on the pathogenic amphibian chytrid fungus ( Batrachochytrium dendrobatidis [Bd]) and the other on the herbivorous cactus moth ( Cactoblastis cactorum) in the United States, where it is not native.

    POPULATION ECOLOGY AND INTEGRATED MANAGEMENT OF SOFT WAX SCALE (CEROPLASTES DESTRUCTOR) AND CHINESE WAX SCALE (C. SINENSIS) (HEMIPTERA: COCCIDAE) ON CITRUS A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University Peter L. La Lincoln University 1994 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Ph.D. POPUlATION ECOWGY AND INTEGRATED MANAGEMENT OF SOFT WAX SCALE (CEROPLASTES DESTRUCTOR) AND CHINESE WAX SCALE (c. SINENSIS) (HEMIPTERA: COCCIDAE) ON CITRUS Peter L. La Soft wax scale (SWS) Ceroplastes destructor (Newstead) and Chinese wax scale (CWS) C. sinensis Del Guercio (Hemiptera: Coccidae) are indirect pests of citrus (Citrus spp.) in New Zealand. Honeydew they produce supports sooty mould fungi that disfigure fruit and reduce photosynthesis and fruit yield. Presently, control relies on calendar applications of insecticides. The main aim of this study was to provide the ecological basis for the integrated management of SWS and CWS. Specific objectives were to compare their population ecologies, determine major mortality factors and levels of natural control, quantify the impact of ladybirds on scale populations, and evaluate pesticides for compatibility with ladybirds. Among 57 surveyed orchards, SWS was more abundant than CWS in Kerikeri but was not found around Whangarei. Applications of organophosphates had not reduced the proportion of orchards with medium or high densities of SWS. Monthly destructive sampling of scale populations between November 1990 and February 1994 was supplemented by in situ counts of scale cohorts. Both species were univoltine, but SWS eggs hatched two months earlier than those of CWS, and development between successive instars remained two to three months ahead.
