This month I’m heading along to the Entomology 2014: The Annual Meeting of the Entomological Society of America, 16-19 November in Portland, Oregon.
This will be the first time I’ve attended an ESA meeting and I’m really looking forward to it. These are large meetings with thousands of delegates, a big change from our recent Mosquito Control Association of Australia conference that attracted about 150 attendees! There is little doubt that I’ll be kept busy getting along to just a fraction of presentations I’m interested in. You can check the program yourself here.
A couple of interesting things I’m looking forward to (notwithstanding the coffee, record shopping and doughnuts) is the workshop on scientific writing, How not to write like a scientist, and a session on the role (or perhaps lack of a role) arthropods play in Ebola virus transmission. I’ve written about why mosquitoes don’t spread Ebola here.
I’ll be giving a couple of presentations, one on the role of mosquito repellents in managing mosquito-borne disease risk and another on the use of social media to promote public health messages. Both of these invited presentations are sure to be fun. It will be nice to catch up with some old friends during the repellent symposium. I recently contributed a book chapter to the new handbook on insect repellents edited by the session organizer/moderator Mustapha Debboun (alongside Dan Strickman and Steve Francis). the symposium.The social media session will be fun too and, apart from sharing my experiences in using social media to promote public health messages, it will be great to catch up with many wonderful people who’ve made my experience on Twitter in recent years so rewarding.
My PhD student, David Lilly, will also be speaking on his work studying insecticide resistance in bed bugs. The abstracts for all these presentations are below but please note that due to the nature of some symposium, not abstracts are included on the Entomology 2014 online program.
1. Finding a place for mosquito repellents in mosquito-borne disease management: An Australian perspective
Mosquito-borne disease is a growing concern for local authorities in Australia. While broad scale mosquito control programs reduce nuisance-biting impacts in some instances, in most regions where mosquito-borne pathogens, particularly Ross River virus, pose a public health risk, local authorities rely on the promotion of personal protection measures. A key component of such strategies is the use of topical insect repellents. There is little evidence that confirms their effectiveness in preventing disease. However, many studies have indicated that the correct use of topical repellents can protect against biting mosquitoes. As a result, it is likely that the promotion of topical insect repellents will remain a critical component of personal protection measures. If they’re here to stay, health authorities must ensure the public is aware of how to effectively choose and use repellents. Currently, there is a disjointed approach to repellent advice provided by state and local authorities. What is needed is a national approach that sets the framework for

2. The importance of methodology and strain selection when determining efficacy of insecticides against bed bugs
Lilly D, Webb CE and Doggett SL
Selection of an appropriate bioassay technique and insect strain(s) are known to be important factors when attempting to accurately detect and monitor for insecticide resistance or define the efficacy of an insecticide. Recent studies with both susceptible and resistant strains of the common bed bug, Cimex lectularius, have indicated these principles similarly apply to bed bugs and must be considered prior to undertaking diagnostic bioassays. Age, access to a blood meal, and the period since repletion may all influence the outcomes of bioassays with bed bugs. Dry residual deposits of insecticides, in particular those of neonicotinoids, also have the potential to overestimate resistance ratios or provide a false negative indication of efficacy when viewed in comparison to more applicable topical or wet residual exposure methods. Resistance monitoring of Australian field strains has also revealed that a wide spectrum in the magnitude of resistance can exist between strains that express identical resistance mechanisms, and that laboratory strains held in culture for long periods of time may lose resistance or change resistant genotypic frequencies. When factored in to the proliferation of field strains with various combinations of multiple and/or cross resistance mechanisms, this clearly presents a challenge to product manufacturers, registration bodies, and pest managers as to how they can ensure the experimental methodology and strain selected is most appropriate for the desired purpose or outcome. The results of laboratory investigations to provide informed guidance on recommended ‘best practise’ bioassays with bed bugs will be presented.

3. Can social media extend the reach of public health messages?
Increasing the exposure of public health messages is critical. This is particularly the case for mosquito-borne disease where advice on personal protection measures often informs the first line of defense against biting mosquitoes. Traditional media has been the mainstay of communication efforts by local authorities but could the use of social media provide a new vehicle for disseminating information and engaging with the wider community? The aims of this study were to determine if promotion and engagement via social media influenced how online information is accessed. A range of social media platforms, particularly Twitter, were employed to disseminate public health messages and engage the community and traditional media outlets. The total weekly exposure of “tweets” was measured for six months with approximately 40,000 people per week received tweets with maximum exposure of almost 190,000 people in a single week. Engagement with the accounts of traditional media (e.g. radio, print, television, online) was found to be the main route to increased exposure and, subsequently, to increased access of public health information online. With the increasing accessibility of the community to online resources via smartphones, researchers and public health advocates must develop strategies to effectively use social media. Many people now turn to social media as a source of news and information and those in the field of public health, as well as entomological research more generally, must take advantage of these new opportunities.
If you’re attending the meeting, please say hi if you’re passing by and feel free to introduce yourself using your twitter handle! If you’re not at the meeting, you can keep track by following the hashtag #EntSoc14. I’ll be trying to tweet about bits and pieces during the conference so please join the conversation!
