Male annihilation technique (MAT) is a key component of management of the Oriental fruit fly, Bactrocera dorsalis Hendel (Diptera: Tephritidae), because of the ‘strong’ attraction of males to the lure methyl eugenol. The optimal application density for MAT has not been investigated for this economically important pest species. We tested the effect of two levels of MAT application density compared to a no-MAT control on the daily survivorship of male and female B. dorsalis estimated by mark-release-recapture (MRR) using a 1-km2 passive sampling network. Estimated daily survivorship from two separate MRR trials under control (no MAT) conditions was 0.751 for males and 0.948 for females. Male survivorship was similar under control (no MAT) and high application density (256 spots km−2; daily survivorship 0.704). However, estimated male survivorship was significantly lower under the low application density (100 spots km−2; daily survivorship 0.211). A similar pattern was observed in estimated female survivorship, with a significant reduction in survivorship under the low rate compared with control and high application density (low-density estimated survivorship 0.652, high density 0.881). The results suggest that a lower application density may be more effective against B. dorsalis than the high application density. A lower application density for effective MAT would benefit growers and the public with respect to management of B. dorsalis through reduced labor and material costs, limiting potential environmental impacts, and increased logistical simplicity finding application sites in urban environments. © 2017 The Netherlands Entomological Society

Phytophthora ramorum Werres, De Cock & Man in't Veld, causal agent of sudden oak death (SOD) and ramorum blight, has been detected in container-grown plants, soil and irrigation ponds in various United States' nurseries. Phytophthora ramorum has also been detected in runoff water from some nurseries and adjoining streams. Despite emergency regulatory actions, there is concern that P. ramorum infected nursery stock may further spread the disease in the United States of America (USA), particularly to previously unaffected wildlands. If established in the south-eastern USA, it could cause damage similar to that occurring in the coastal forests of California and Oregon. To develop solutions for nurseries that trade plants susceptible to P. ramorum, a quarantine nursery was established in Marin County, California, to investigate pa thogeneradication and disease management. More than four years of collaborative efforts between the California Department of Food and Agriculture, California county Agriculture Commissioners, the California Oak Mortality Task Force, US National Plant Board, United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine and nursery industry resulted in locating a suitable site for developing the National Ornamentals Research Site (NORS) at the Dominican University of California (DUC). Funding to set-up and run the research nursery was awarded in 2008 through congressionally approved, Farm-bill (Section 10201) funding. The site is designed to perform research on quarantine pests and pathogens while safeguarding plant health and the surrounding natural environment. Research initiatives on P. ramorum have commenced at the NORS-DUC. Research grants are awarded to undertake research at the NORS-DUC and proposals can be submitted through www.dominican.edu/norsduc. © 2011 New Zealand Forest Research Institute Limited. trading as Scion.
