Debug Fresno, our first U.S. field study
Friday, July 14, 2017
Last October, we announced the
Debug Project
, an initiative at Verily to reduce the devastating global health impact that disease-carrying mosquitoes inflict on people around the world. Today, I’m happy to announce the launch of
Debug Fresno
, our first field study in the U.S. to test a potential mosquito control method using sterile insect technique in collaboration with
MosquitoMate
and Fresno County’s
Consolidated Mosquito Abatement District
(CMAD).
Debug Fresno will target the invasive
Aedes aegypti
mosquito, which can transmit diseases like Zika, dengue, and chikungunya.
Aedes aegypti
first appeared in the central valley of California in 2013, and since then has become pervasive in Fresno County. This study will be the largest U.S. release to-date of sterile male mosquitoes treated with
Wolbachia
, a naturally occurring bacterium, and will take place over a 20 week period in two neighborhoods each approximately 300 acres in size. When these sterile males mate with wild females the resulting eggs will not hatch. To measure our outcomes, we will compare the adult population density and egg hatching of
Aedes aegypti
in these targeted areas to two control neighborhoods. Over time, we hope to see a steep decline in the presence of
Aedes aegypti
in these communities.
In 2016, CMAD and MosquitoMate piloted the first-ever U.S. release of male
Aedes aegypti
mosquitoes with
Wolbachia
in Fresno County. Our 2017 collaboration represents a more than 25x increase in the release efforts, with a total of one million non-biting sterile male mosquitoes released weekly, made possible by the automated mass rearing and sex-sorting processes developed at Verily. Additionally, our software algorithms and on-the-ground release devices will allow us to distribute the sterile male mosquitoes in an even and targeted way throughout Fresno’s mosquito season. We believe that these advancements could have a meaningful impact on what is traditionally a very labor-intensive process and could reduce the number of biting
Aedes aegypti
in Fresno County.

For the Debug team at Verily, moving our work from the laboratory to the field is not only an important milestone for our group of biologists, engineers, and automation experts, but it’s also a critical step in bringing our long-term vision to reality. Field studies allow us to test our discoveries and technologies in challenging, real-world conditions and collect the necessary evidence to bring them to a broader scale. We hope to demonstrate success with Debug Fresno that will benefit the local communities working with us on this study and later other communities globally where Zika, dengue, and chikungunya are endemic. We are excited to take the first step in that journey today by bringing these technologies to the field.

Announcing our collaboration with Consolidated Mosquito Abatement District
Friday, March 24, 2017
Today, we’re delighted to announce that we have partnered with the Consolidated Mosquito Abatement District (CMAD) in Fresno County, California to better study the local infestation of invasive
Aedes aegypti
mosquitoes.
A regional government entity formed shortly after World War II, CMAD brings not only decades of experience in mosquito control, but also direct experience with innovative control techniques. We’re fortunate to be joined in this effort by
MosquitoMate
. They have previously
partnered
with CMAD to study the effect of
Wolbachia
mosquito releases.
We look forward to a fruitful collaboration against one of mankind's bitterest foes.

Announcing our partnership with MosquitoMate
Tuesday, February 14, 2017
We are happy to announce that we have entered into a partnership with
MosquitoMate
to test our automated mosquito rearing and release technologies. Founded in 2010 by University of Kentucky professor Stephen Dobson, MosquitoMate has extensive experience using male
Aedes
mosquitoes infected with
Wolbachia
as a mosquito control tool, making them a natural partner in our mission to scale the sterile insect technique (SIT) and locally eliminate invasive
Aedes aegypti
mosquitoes. We look forward to working together.

A research update from our colleagues at CSIRO
Thursday, January 12, 2017
We thought we’d start 2017 by sharing some results of the Queensland fieldwork being conducted by our Australian partners, the Commonwealth Scientific and Industrial Research Organization (CSIRO) and James Cook University (JCU). The original post "How far will a male mosquito travel to find a mate – and will he cross the road?" from December 22, 2016 is available

on the CSIRO mosquito project blog.

How far will a male mosquito travel to find a mate – and will he cross the road?
By Helen Cook, CSIRO
Compare the pair: red dye was used to mark mosquitoes.
No, it’s not a joke. Pose this question to a member of our local Innisfail mosquito research project and they’ll give you a straight answer – On average less than 100 metres, and yes but most prefer not to. Yes, male mozzies
[Australian for mosquito]
do cross the road, or at least Mourilyan Road in East Innisfail where the project team has been studying the behaviour of the male Aedes aegypti mosquito; the female of the species transmits the dengue and Zika viruses.
Over the course of the five-week ‘Mark, Release Recapture’ (MRR) study 3000 male mosquitoes marked with a dye were released and then recaptured through a network of over 70 traps set in residents backyards, all to see how far the mosquitoes fly, how quickly they mate and how long they live. “The long-term goal of our research in Innisfail is to show that we can suppress and even remove the invasive Aedes aegypti mosquito from the urban landscape,” Project Manager Helen Murphy said. “Understanding the behaviour of the male mosquito is key to achieving this goal.”
“In 2017 we hope to carry out further studies and test new technologies being developed in the USA by project partner Verily [a Google affiliate]. These studies will involve releasing male mosquitoes that are effectively sterile,” Dr Murphy said. “If the sterile male mates with a wild female, the eggs she lays won’t hatch, thereby limiting the number in the next generation of Aedes aegypti. If we get our numbers right this would mean that the Aedes aegypti population would quickly die-off in the community.”
The CSIRO Innisfail mozzie team released over 3000 males mosquitos in East Innisfail, far north Queensland, where with residents support they had set over 70 traps – all to see how far the mozzies would go to find a mate.

In the New Year the project team will expand their community engagement activities to share their plans with Innisfail residents, describing a small study to release sterile male mosquitoes in the first half of the year. If this is supported and successful, the project team will plan for a larger study towards the end of 2017.
“These initial studies in Innisfail will be the first of their kind carried out internationally as part of our recently launched
Debug project
,” Debug Product Manager Dr. Nigel Snoad said. “We are pleased with the initial results from the MRR and the high level of community support for our work, but we’re really just at the ‘preschool’ stage of what is a long-term world-wide project,” he said. “Working with CSIRO and James Cook University we expect to learn a lot by doing the next set of studies in 2017. We want to see the back of these bad bugs not only in Innisfail but across the world.”
