BPIA 2017

The Biopesticide Industry Alliance (www.bpia.org), which is dedicated to advancing knowledge about biopesticides, will hold their 2017 Spring Meeting & International Symposium on February 27-March 1, 2017 in Reno, NV.

Strategies and issues in biopesticides, biostimulants, and global challenges will be presented and discussed during this three day event.

Lacey Jenson, Semiochemical Registrations Manager along with Sales Manager Izzy Heller, will be in attendance and representing the Bedoukian group at this event.

Meet Bedoukian's Registrations Manager

Dr. Lacey Jenson is the newest member of the Bedoukian Research, Inc. team! Lacey joined the Regulatory department at BRI in November 2016 with the role of Registrations Manager.

Lacey was a Post-Doctoral Fellow in the Department of Entomology and Fralin Life Science Institute at Virginia Tech under the supervision of Dr. Troy Anderson. She was leading research studies that focused on the characterization of drug transport proteins and ion channel physiology of insects with research interests spanning ion channel pharmacology, insecticide mode of action, cell biology and neurotoxicology.

Lacey received her PhD in Entomology and Nematology (2013) from the University of Florida under the advisement of Dr. Jeffrey Bloomquist. Her dissertation research focused on the characterization of insecticide target-site protein expression in hormonally-induced insect cell lines.

Dr. Jenson’s previous education includes a Master of Science in Entomology in 2010 from Virginia Tech. Her thesis research was conducted on the development of a hormonally-induced cell assay for the highthroughput screening of existing and experimental insecticides. Lacey has also earned a Pre-Health Professional Bachelor of Science degree with a Minor in Microbiology from Iowa State University in 2007.

Lacey will be handling our semiochemical registrations with US EPA, Canada’s PMRA and EU’s Plant Protection and Biocide Regulations. She’ll be representing us at future BPIA and IBMA meetings so please introduce yourself. We’re thrilled to have Lacey join us!

Ardent Rose Perfume Benefiting Roses for Autism

In a unique collaboration, Bedoukian Research worked with Robertet Fragrances and The Design Spot to develop “Ardent Rose”, a captivating fresh floral scent infused with rose absolute and white amber to convey an intriguing and sensuous feminine statement.  The fragrance represents the legacy of the beautiful and aromatic roses grown within the Roses for Autism greenhouses in Guilford Connecticut. The fragrance was developed for Roses for Autism --  a Connecticut based non-profit organization that provides scholarships, career training, and job opportunities for autistic young adults. Ardent Rose is being sold directly through the Roses for Autism website.  All proceeds go directly to Roses for Autism to support their social enterprise programs.

1) Indirect Aphid Control with Low Concentration of EBF

Patent # US 5,308,613 (1994 Banfield, Consep Membranes)

ABSTRACT:  An indirect control of aphids is disclosed, comprising the use of relatively minute concentrations of the pheromone E- β-farnesene, which prevents aphid-caused crop damage by warding off aphids and by attracting natural aphid predators and parasites.

2)   Trans-β-farnesene, Alarm Pheromone of the Green Peach Aphid, Myzus persicae (Sulzer)

Nature (Impact Factor: 42.35). 01/1973; 241(5385):126-127. DOI: 10.1038/241126b0

By: L.J. Edwards, J.B. Siddall, L.L. Dunham, Peter C. Uden, C.J. Kislow

ABSTRACT: The chemical structure of the repellent odour found in the cornicle secretion of the aphid M. persicae1 has been identified as trans-beta-farnesene.

Abstract: A review.  Aphids are important agricultural and forest pests that exhibit complex behaviors elicited by pheromonal signals.  The aphid alarm pheromone, of which (E)-β-farnesene is the key (or only) component in most species, plays important roles in mediating interactions among individuals as well as multitrophic interactions among plants, aphids, and aphid natural enemies.  Though many important questions remain to be answered, a large body of research has addressed various aspects of the biol., physiol., and ecol. of aphid alarm pheromones.  Here we review recent advances in our understanding of (1) the identity and compn. of aphid alarm signals; (2) their biosynthesis and prodn.; (3) their effects on conspecifics; (4) their role as cues for other insect species; and (5) their potential application for the management of pest organisms.

Abstract: A review.  Domestic and international scientific collaboration over recent years has led to important achievements in basic research and control techniques for wheat and vegetable aphids.  Behavioral manipulation technol. has improved through the investigation of the effectiveness of slow released infochems., e. g. aphid alarm pheromone [(E)-β-Farnesene, EBF]], in repelling aphids and attracting their natural enemies.  This research has clarified the correct dose of infochem. oil in the slow releaser and the effective height of infochem. dispensers above host plants, plus the possibility of coordination with the application of EBF and insecticides.  In addn., "push-pull" techniques have been developed that use crop diversity to control aphids.  These unequivocally demonstrate that intercropping, or mixing wheat with other crops, has a valuable control effect on aphids, and allows optimal models to be selected base on the required aphid population decrease, the importance of preserving natural enemies and the Land Equiv. Ratio.  Plant resource insecticidal component screening has found some bioactive components in Macleaya cordata exacts (MCE), e. g. alkaloids, and plant lectins that are highly toxic to wheat aphids.  A formula contg. sanguinarine from MCE and nicotine has been developed that can achieve a mortality among aphid populations of 98.9%; new crop protection technologies have been integrated and demonstrated in wheat and vegetable fields in Henan, Hebei and Shandong provinces, and a socio-economic survey and evaluation system adopted to adjust control methods based on feedback from farmers and technol. transfer agencies.  The final proposed solns. are adapted to local conditions and are therefore more sustainable and efficient, limit the neg. effects of the conventional pesticide use, enhance farmers' income, and ensure food safety.

Abstract: The aphid alarm pheromone (E)-β-farnesene has a neg. impact on aphid pests and increases foraging by antagonistic organisms such as aphid parasitoids.  Genetic engineering in an elite wheat variety has produced stable expression of highly pure (E)-β-farnesene giving excellent results in the lab. against cereal aphids and in increasing foraging by braconid parasitoids of aphids.  Field trial results are currently being analyzed.  New targets for other semiochems., in addn. to pheromones, are studied.  These are chosen when evidence of their effectiveness is available from agroecol. systems exploiting companion cropping to release semiochems. for crop protection and includes a series of defense related isoprenoid oxidn. products.  Induction and primed release of the pheromones and other semiochems. is being developed via natural plant defense elicitors.  The work extends to pathogens and weed control, and even to plant prodn. related traits.

Abstract: The sesquiterpene (E)-β-farnesene (Eβf) is the primary component of the alarm pheromone of most aphid species.  It is released in response to phys. stress including attack by natural enemies and causes aphids to cease feeding and disperse.  Eβf also acts as a kairomonal cue for aphid natural enemies.  In this study, the authors collected the headspace volatiles released by aphid (Myzus persicae) colonies of different sizes.  Gas chromatog.-mass spectrometry anal. demonstrated the presence of Eβf in the absence of predator attack.  A quadratic relationship was found between the released (E)-β-farnesene amts. and aphid colony size.  Behavioral impact of aphid alarm pheromone towards Episyrphus balteatus female oviposition behavior was also demonstrated.  These results highlight the primary role of the small but continuous release of aphid alarm pheromone in mechanisms of decision-making by aphid predators during their foraging and egg-laying behavior.
