Nanoose Bay, BC CANADA Highlights of the ANBP Annual General Meeting in Guadalajara, Mexico New President and new Board Member start the ANBP year Once again, Guadalajara, Mexico, proved to be a wonderful location for our ANBP Annual General Meeting. The attendees enjoyed two full days of networking amid informative talks, good food, nearby attractions, and an outstanding conference banquet. In addition to the programmed portion of our meeting (see the ANBP website for speaker list), our official agenda included honoring Don Elliott as the ANBP Award of Excellence recipient for 2013, electing Brian Spencer (Applied Bio-nomics) to ANBP President, and choosing John Maurer, Evergreen Growers View from the El Tapatio Hotel in Guadalajara, Mexico. The venue and Supply LLC, as a new ANBP hospitality for our Annual General Meeting (Nov. 13-15, 2012) couldn’t have Board Member. After many years been better. The weather and wonderful food were an added bonus. of very dedicated service, Carol Glenister (IPM Laboratories), stepped down from the Board, but we are confident she will continue to be an active participant in many ANBP functions. Thank you, Carol, and welcome John! We heartily thanked Eda Reinot (Becker Underwood), for her past two years as ANBP President, who included focusing our goals after a follow-up Strategic Plan she directed at the start of her term.

With a unanimous decision, I have a glorious mandate to ram through all of my controversial ideas. I still can’t believe that you voted for me! ANBP’s Mission is to address key issues of the biological control industry through advocacy, education, and quality assurance. “Bio-control Matters” is published by the Association of Natural Bio-control Producers four times per year to provide members with information, thought, and opinion on biological control topics. Biocontrol Matters advocates the interests of commercial biological control and the public interest of quality agricultural production and environmental protection. Bio-control Matters welcomes contributions of comment and opinion, as well as articles of general interest. All contributions must be signed by the contributor. Send contributions for consideration to Lynn LeBeck, ANBP Executive Director, P. O. Box 1609, Clovis, CA 93613-1609. Phone (559) 360-7111. Contributions may also be sent to [email protected]. Published contributions may not necessarily reflect the views or policy of ANBP. ANBP was formed in 1990 by commercial insectaries to provide a united voice in regulatory issues facing the industry. ANBP is also dedicated to quality standards and educating the agricultural and academic communities about the importance of biological pest controls for pest management. Through its efforts, ANBP is recognized as THE spokesman for the commercial biological control industry. First, and foremost, I want to build on Eda Reinot’s fine leadership in the area of increasing our membership and awareness of ANBP. We have chosen our Spring 2013 meeting place as Oxnard, California. This is because most of our member’s, or, at least the statistically mean distribution of our membership, resides within 100 miles of our meeting place. We really need all of the members in the area, or, those who can think of a reason to travel to Oxnard on March 12, to attend our meeting. If we don’t get a turn out that backs this decision, it will allow us to pick exotic meeting locations at our whim. And trust me, you don’t want that. This has been a tough decade, and, there is no end in sight. Fiscal cliffs, rising oil prices, rising tides, lowering barometric pressures, rising barometric pressures, rising payroll taxes, drought, new gun control regulations all make our jobs that much tougher to do and tighter to balance. You can’t afford to spend your money where it doesn’t do something directly for you or your business. You need to get your money’s worth from your membership. Clearly, our group’s major role is to Educate. Educate our regulators about what we are doing. Educate our Politicians about our industry’s importance and value. Educate our customers about what we are capable of doing. Educate researchers about our needs. And educate the public about Biological Pest Control. We are doing a very good job in this role. Another historical role is advocacy. In the past, when governments or regulators were about to make serious decisions that related to us, we rose to the occasion and quelled the mighty beast. I like to think that if we do a good job educating, the need for advocacy is reduced. This is a good thing, because, we are a small group, and, the cost of advocacy is very large. Our strategy, therefore, should be to make strategic alliances with larger industry groups. If we find the right industry groups, our involvement with them should help strengthen their position also. A synergy. So, what strategic alliances should we make? Or should we make any? I want to deal with this question at our Spring Board meeting. If you can, please come to join in on the discussion. If you can’t come, send us your thoughts. The nice thing about a small group is; you really do have a voice, and a say, as to what direction we will take. Be warned. I am not afraid to make decisions, or to take actions. If we, as a group, decide on a direction, it will happen. Brian Page 3 ANBP Student Poster Award Winner is Laura Hewitt, University of Guelph We are very pleased to announce that Laura Hewitt was ANBP’s student poster award winner this year at the 2012 Joint Annual Meeting of the Entomological Society of Alberta and the Entomological Society of Canada, in Edmonton, Alberta, Canada, November 3-7, 2012. This award (plus $250) is given to the best poster or presentation by a student with research in applied biological control. Laura’s work with predatory mites against thrips in a greenhouse system was an ideal subject for ANBP and she did a great job on the poster. She, and her co-authors, graciously provided a nice, expanded abstract for our Newsletter. Congratulations Laura! Determining the better thrips predator: the effect of seasonal variability on predatory mites in ornamental greenhouse IPM Laura Hewitt (M.Sc. candidate)1, Cynthia ScottDupree1, Les Shipp2 and Rose Buitenhuis3 1 School of Environmental Sciences, University of Guelph, Guelph, ON N1G 2W1 [email protected]; [email protected] 2 Agriculture and Agri-Food Canada, 2585 County Road #20, R.R.#2 Harrow, ON, N0R 1G0, [email protected] 3Vineland Research and Innovation Centre,, 4890 Victoria Ave. N., Box 4000, Vineland Station, ON L0R 2E0, [email protected] Laura Hewitt, University of Guelph. The rapidly growing Ontario greenhouse industry provides a healthy supply of vegetables and ornamental plant material year-round to national and international markets. Because greenhouse production is a very intensive agricultural practice, in order to balance costs and net profit while ensuring a quality product is delivered to the consumer, greenhouse growers are often faced with tough decisions of how funds will be allotted. Western flower thrips (Frankliniella occidentalis) (WFT) are a major pest of flowers and vegetables in commercial greenhouse production. Their cryptic lifestyle and ability to rapidly developed resistance to insecticides allows them to cause serious cosmetic damage to ornamental crops (e.g., chrysanthemums), resulting in substantial economic losses. The predatory mites Amblyseius swirskii and Neoseiulus cucumeris are commercially available as primary biocontrol agents (BCAs) used for WFT control. Although morphologically quite similar, A. swirskii originate from a dry hot climate, while non-diapausing N. cucumeris were originally isolated from a more temperate climate. When purchased from BCA suppliers in Canada, A. swirskii often cost at least double that of N. cucumeris. Unlike specialty ornamental crops, chrysanthemums are produced year-round in Ontario greenhouses. Therefore, a need exists for efficacious predatory mites in all seasons. Due to life history characteristics and anecdotal evidence from growers, Laura Hewitt has been investigating the impacts of the seasonal climatic variables: temperature, light intensity and photoperiod on the efficacy of these predators in lab bioassays. She also has conducted greenhouse studies to determine the efficacy and longevity of mite populations when applied to a thrips-infested ornamental crop. During the summer (June-July) and winter (November & February) 2011 and 2012, efficacy of A. swirskii and N. cucumeris was evaluated in greenhouses. Small mesh-sided cages containing a 15cm potted chrysanthemum plant were infested with thrips. A week later, cages were randomly assigned a treatment of either 50 Continued next page... Page 4 Bio-control Matters Award continued N. cucumeris or A. swirskii, or remained a no-mite control. Four plants of each treatment were sampled each week (12 plants/week) for the following 4 weeks. Numbers of thrips and mites present on each sampled plant were recorded. Fifty leaves from each sampled plant were also dried and assessed for thrips damage. Damage was rated on a scale of 0-2. A score of 0 was given for no visible damage on the leaf, 1 for 1-3 feeding scars of 1mm or less, and leaves with 4 or more feeding scars were heavily damaged and assigned a rating of 2. Both mite species were evaluated on their ability to reduce existing populations of WFT, reduce cosmetic damage caused by WFT feeding and oviposition, and increase and maintain their population over the course of the trial. To expand on these trials, similar experiments were conducted in commercial production greenhouses during summer and winter. Fifty mites per plant were applied biweekly to plots of chrysanthemums containing a natural WFT level. Mite population survival and WFT reduction potential were monitored each week by sampling and counting the mites and thrips found on the plants. In winter, both A. swirskii and N. cucumeris reduced thrips population levels on chrysanthemum plants within the greenhouse (Figure 1). Heavy feeding damage was also significantly decreased in the presence of the predatory mites (Figure 2). During the 4-week trial, the populations of mites were equal in both species. During the summer, thrips populations in the greenhouse were again reduced by both mite species; however, A. swirskii reduced the number of thrips per plant to a lower level (Figure 3). Population levels of A. swirskii also remained higher than those of N. cucumeris from week-to-week. Heavy feeding damage was once again reduced by both mite species (Figure 4). Figure 1. Mean number of western flower thrips on Neoseiulus cucumeris and Amblyseius swirskii treated chrysanthemum plants (cv. Chesapeake) in small cages in a greenhouse over four weeks during the summer. Data points with different letters indicate a significant difference (P=0.05) between treatments and weeks. Figure 2. Mean number of leaves with heavy (4 or more feeding scars), light (1-3 feeding scars of <1mm), or no visible western flower thrips feeding damage four weeks post-treatment in a greenhouse during summer. Treatments were Neoseiulus cucumeris, Amblyseius swirskii, or no-mite control. Data points with different letters indicate a significant difference (P=0.05) between treatments. Based on these findings, during the winter months of Ontario, N. cucumeris is just as effective as A. swirskii for the control of western flower thrips. Furthermore, because N. cucumeris costs about a third of the price of A. swirskii, it is the most cost-efficient choice for growers. Recommendations for summer growing periods are not as clear-cut. Amblyseius swirskii outperformed N. cucumeris in thrips control and maintained a larger population within the crop. However, with the large price disparity, it is difficult to de- Volume 10 Issue 4 Page 5 Award continued Figure 3. Mean number of adult western flower thrips on Neoseiulus cucumeris, and Amblyseius swirskii treated chrysanthemum potted plants (cv. Chesapeake) in small cages in a greenhouse over four weeks during the winter. Data points with different letters indicate a significant difference (P=0.05) between treatments and weeks. Figure 4. Mean number of leaves with heavy (4 or more feeding scars), light (1-3 feeding scars of <1mm), or no visible western flower thrips feeding damage four weeks post-treatment in a greenhouse during winter.

Data points with different letters indicate a significant difference (P=0.05) between treatments. termine whether spending the extra money on A. swirskii is a worthwhile investment. What is clear is that release rate recommendations need to account for seasonal climatic conditions, and not just rely on the crop type and pest levels within the crop. Further studies involving these predatory mites should investigate the option of applying twice as many N. cucumeris to plants during summer months to possibly increase their efficacy. A greater understanding of seasonal effects will aid in the improvement of recommendations for application rates and timing for effective year-round thrips control in greenhouses.

Page 6 Bio-control Matters ANBP Committee Reports ANBP Regulatory Committee Update Chair, René Ruiter, Koppert René As communicated in the last newsletter, in this update we’d like to keep everyone abreast of the most current developments. First a continuation of current initiatives: Canada: Canadian Food Inspection Agency (CFIA) The ‘best management practices’ on bumble bee management will be published by the CFIA (Canadian Food Inspection Agency) and get in the hands of growers by means of informational hand-outs and posters. As soon as the best practices have been communicated and this CFIA initiative has been completed, ANBP’s involvement will shift to monitoring of the developFor a direct look at ments. A November 2012 deadline was established to provide feedback to CFIA regarding CFIA's Plant Protection Policy Directive D-12-02. The easiest way to explain the change CFIA proposes is to go back to a permitting system for all beneficial insects in place of the current system of working with HScodes for import only. The implications for the industry of this proposed change is not totally clear yet, but ANBP appreciates the opportunity to be in contact with CFIA and will monitor this situation as well. RSPM 26, visit the NAPPO website at this link: http:// www.nappo.org/en/data/ files/download/Standards/ RSPM26-01-06-12-e.pdf United States: USDA-APHIS (APHIS) and the US Fish & Wildlife Service (USFWS) Informally, USDA has announced that new regulations affecting the biocontrol industry will be put in place, but a timeline for the publication and public comment period for these regulations are not known yet. ANBP is in close contact with APHIS in order to give the industry a voice once the comment period opens. Some ANBP members have voiced concerns regarding the development of individual states regulations and / or lists of approved arthropods changing at the state level. Current federal regulations do imply state consent, but individual states may regulate permits in addition to federal standards. ANBP will start getting involved in this development by developing an inventory of regulatory requirements of those states that differ from, or have additions to, the federal standards. Once we have a clear overview, steps will be determined to see if ANBP can offer facilitation in this area. Another ‘to-do’ item for ANBP is to continue our communication with the USFWS. The USFWS typically does not get involved with the importation of beneficial insects, but some inconsistencies have been occurring in this area. The USFWS does not regulate the movement of domesticated animals and the definition for insects in this regards is: Insects: crickets, mealworms, honeybees (not to include Africanized varieties), and similar insects that are routinely farm-raised. As it is clearly not the intent of the USFWS to regulate biocontrol organisms that are raised in laboratories, ANBP wishes to clarify this with the USFWS and broaden the definition of insects that do not fall under their umbrella to include laboratory or farm-raised biocontrol organisms. A letter has been sent to the USFWS now that they have a permanent new Director.

The majority of this acreage is located in the San Joaquin Valley where native pests, such as the grub Cyclocephala longula, have acquired a taste for blueberry plants. Grubs in the genus Cyclocephala are most recognized as pests of turf, where they thrive on shallow-rooted plants, with good soil moisture, and a thatch layer with high levels of organic matter. Blueberries provide a similar environment due to their shallow root systems, constant and uniform soil moisture from drip irrigation, and fertilization programs based on massive use of compost and mulch. Feeding by grubs on the blueberry root systems causes stunting of plants, increases in root diseases such as phytopthora, and in severe cases can cause plant death. Soil and root conditions that allow grubs to become a pest are also conducive to the survival of the entomopathogenic nematode Heterorhabditis bacteriophora. During 2009, University of California researchers teamed up with members of the blueberry industry to evaluate the potential role of this entomopathogenic nematode against Cyclocephala longula in commercial blueberry fields in the southern San Joaquin Valley of California. Nematode-infested grubs collected two months Studies were done by applying one billion following an application of H. bacteriophora infectious juveniles per treated hectare of the through the drip irrigation system. commercial nematode product TerranemTM (Koppert Biological Systems, Inc.) through the drip system. In the first study, applications were made in the spring on April 1 as soon as soil temperatures reached 15°C. During the first month after application the percentage of infected grubs was relatively low (8.3%). However, secondary Continued next page... Page 8 Bio-control Matters Nematodes against grubs continued spread of nematodes within the belowground populations of grubs led to an epizootic that reduced overall population to negligible levels within four months. In the second study nematodes were applied in August as eggs from the summer flight of adult beetles had mostly hatched. Ten months later, plots where nematodes were applied had an 81.6% reduction in grubs compared to the untreated check; this was statistically equivalent to the level of control achieved by the chemical standard program using imidacloprid. Due to the successful control of grubs in field research, entomopathogenic nematodes have become the standard control method for grubs in organic blueberries in California, and have joined imidacloprid as the principal method for control in conventional berries.
