My recent paper with Travis Collier on evaluation of quarantine lengths was featured as a highlight in the FAO/IAEA Insect Pest Control Newsletter Number 90) on pg 36.

12 December 2017

I've created a publons account to track my peer reviews. My profile is is here. This is an interesting effort, though many researchers might hesitate due to confidentiality issues. I have been signing my reviews over the last few years, so for me this is not an issue.

17 October 2017

Three papers published in quick succession this month, two from work started in 2014 (Jang et al and Gaertner et al) and another in 2016 (Khan et al). Great to have these complete.

This has been a very busy year for travel: Brazil, Austria, New Zealand, Taiwan, Kauai, and finally Denver CO. Most sponsored, but still a lot of time on the road.

28 June 2017

Welcoming a few new people in our lab for the summer. One is Briana McCarthy, a professor at Los Medanos CC in N. California. She is joining us through the USDA Hispanic-Serving Institutions National Program's Kika de la Garza Fellowship Program, and will be focused on CBB with Melissa Johnson. The other are Jana and Alyssa, HS students at St. Joseph HS in Hilo. Welcome to all three!

24 May 2017

I am presenting some of our recent ABS results at Third FAO–IAEA International Conference on Area-wide Management of Insect Pests. In a couple of weeks I will be in Ribeirão Preto, Brazil, at the 15th SICONBIOL, to discuss some of the experience with biological control of tephritids in the Pacific.

1 February 2017

Melissa Johnson has started today in my lab! Melissa is a postdoc who will be working on our Coffee Berry Borer (CBB) research. She is an expert in the genus Cyrtandra, and has experience in molecular phylogenetics, speciation in plants and taxonomy. In addition, she has conducted significant field work around the Pacific, in Hawaii, California, Samoa and Fiji. We are delighted to have her help and look forward to a very productive postdoctoral appointment.

01 July 2015

New release of MED-FOES (ver 0.6)! This version includes spatial modeling of an eradication trapping grid via TrapGrid, which is a significant increase in eradication realism. Execution time is longer if this feature is used, but in many cases it will be worth it. In associated news, a couple of papers on trap attraction are now available (here and here).

02 June 2015

A Farm Bill section 10007 suggestion with cooperators at APHIS, NC State and UF has been awareded $170K to model Medfly risk in the continental US. This model will include the entire invasion process, including cost of eradication. This last factor will be modeled using MED-FOES.

22 April 2015

I'm organizing a workshop in Hilo and Kona to further a spatial model of coffee berry borer (CBB) in Hawaii. The expert group at the workshop will include researchers from ARS, NASA and Cornell Univerity. We will be meeting with other CBB researchers from University of Hawaii and also with coffee growers from April 27-May 1.

17 October 2014

Returned to Hawaii from a trip to Juazeiro, Bahia (Brazil), where I was invited to present some results of our stereoscopic mosquito swarm studies to a Research Coordination Meeting (RCM) of the IAEA. I had the opportunity to see from up close the "Projeto Aedes Transgenico", one of the first to release transgenic disease vectors in the world. More on PAT.

31 October 2012

First paper on using computer vision to study the behavior of tephritid flies has been accepted to Annals of the Entomological Society of America. This should be a foundation for further studies using the same basic approach.

Ribeiro et al (J. of the Royal Society Interface) and one a review on biological control of tephritid flies in the Pacific with R. Vargas, L. Leblanc and E. Harris (Insects). A nice bridge between past work and future.

21 March 2012

I have some video showing our use of machine vision for detecting fruit flies on a screen. This is my first time posting a video using the HTML5 video tag, and it was not as simple as I'd hoped- I am not sure this will work on all browsers. Still, you can give it a try if you click here.
