Drs. Jawwad Qureshi and Phil Stansly, and Ph.D. candidate Eric Rohrig, are working with Tamarixia radiata Waterston (Hymenoptera: Eulophidae), a species-specific ectoparasitoid of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae). They are releasing this ectoparasite in both conventional and organic commercial citrus groves in Florida, with 5,150 wasps released in 2009. Parasitism rates are monitored by rearing field collected nymphs of D. citri and exposing infested sentinel plants in the field. These releases were initiated in an attempt to increase early season parasitism by T. radiata after a recently published state-wide survey of Florida citrus demonstrated generally variable and low incidence of the wasp in citrus groves. They are also attempting to establish Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) from southern China throughout the state and are requesting release permits from USDA-APHIS for newly imported strains of T. radiata from Viet Nam, China and Pakistan. - Dr. H. Alejandro Arevalo

Meetings and Presentations
Dr. James P. Cuda and his Ph.D. student Abhishek Mukherjee attended the 24th Annual Symposium of the Florida Exotic Pest Plant Council held in Delray Beach, FL, 26-29 May. Cuda gave the presentation "Synergistic effect of insect herbivory and plant parasitism on the performance of the invasive tree Schinus terebinthifolius (Anacardiaceae)." The presentation was co-authored by Drs. William A. Overholt and Julio C. Medal. Cuda also was a moderator for one of the biological control sessions. Mukherjee presented the paper "Exploratory surveys in India for natural enemies of Hygrophila polysperma: preliminary results," which was co-authored by Cuda.
Dr. James P. Cuda and Abhishek Mukherjee participated in the 2nd Annual Hydrilla and Hygrophila Field Demonstration held at the Kissimmee Lakefront Park, Osceola Co, FL, 4 June. Cuda and Muhkerjee delivered two poster presentations showcasing UF's research activities on classical biological control of the aquatic weeds hydrilla and hygrophila.
Graduate student Lindsey Christ received a $1,000 research grant from the Florida Exotic Pest Plant Council. Lindsey is one of Dr. James Cuda's graduate students and is currently in Brazil studying the field biology and life history of the Brazilian peppertree leaflet galling psyllid Calophya terebinthifolii Burckhardt & Bassett.
Dr. James P. Cuda received a $5,000 research grant from Evonik Industries, one of the world's largest producers of the food additive methionine, to continue investigating biopesticidal properties of this essential amino acid.
Outreach with Maggots!

Entomological Foundation Challenge
The Entomological Foundation announced a national fundraising campaign to establish an endowment to benefit the Entomological Foundation. The goal is to raise $400,000 by December 1, 2009 in partnership with the Branches.
The Education Fund will provide assets to work in perpetuity to meet future funding needs; to fund new programs, projects, and services; or to expand the reach of Foundation programs and services. A portion of the funds raised, $40,000, will be given to an ESA Branch to establish an endowment of their own that will be used to help support educational activities of an ESA Branch including funding for educational outreach activities, workshops, scholarships and awards. The fundraising campaign includes a competition between the ESA Branches and will end when the Foundation reaches $400,000. The ESA Branch raising the largest level of donations (per membership) by the end of the competition will be provided with $40,000.
For more details, contact Dr. Rebecca Baldwin (email@example.com), who is a member of the Foundation's Board of Counselors.
Bees collect pollen from plants and that is good for the plants — right! Well, now there is evidence that many plants do not want bees collecting all their pollen and "work" hard at making it difficult for the bees to collect the pollen. See http://www.sciencedaily.com/releases/2009/05/090517214622.htm for details.
Malaria infects hundreds of millions of people every year and kills one to three million, mostly children. A recent study showed that the spread of malaria parasites was curbed with a combination of methylene blue and new malaria drugs. See http://www.sciencedaily.com/releases/2009/05/090520100506.htm for details.
Ever wonder why bees (and perhaps other Hymenoptera) extend their legs when they fly? See http://www.sciencedaily.com/releases/2009/06/090602122623.htm for the reason.
In water containers across the southeastern U.S., at least one species of midges is hard at work eliminating exotic, invasive mosquitoes, thereby benefiting some native mosquito species. See http://www.sciencedaily.com/releases/2009/06/090604103640.htm for details.
So where does a 20,000 pound African elephant go? Anywhere it wants to, right? Well, not anymore. Not if you have "bee hive fences" around your fields. See http://www.sciencedaily.com/releases/2009/06/090606111040.htm for details.
"Although many beekeepers served in the U.S. Armed forces during World War II, some chose to stay stateside. In fact, beginning in 1942, the Selective Service included beekeeping as an essential agricultural activity allowing local draft boards to grant deferments to individuals whom they felt contributed more to the war effort through their beekeeping activities. The Honey Industry Council was able to persuade the federal government to exempt wood, sugar and metal from rationing to beekeepers because beekeepers supplied beeswax and honey to the government. It was estimated that over one million pounds of beeswax per year were used in war products. When a beekeeper once was denied permission to buy sugar to feed his hives, the secretary for a local War Procurement Board stated without sympathy, ĎWho do you think you are trying to get sugar for your bees, when I can't get sugar for my coffee.' The Board reversed its decision when the beekeeper returned with a bee inspector who threatened a federal lawsuit." - from Bees in America: How the Honey Bee Shaped a Nation by Tammy Horn
