The Northeastern Integrated Pest Management at Cornell will be hosting three webinars in September 2017 that could be of interest to people following arboviruses, disease, vectors, pests and/or control. Their webinar series, called “The IPM Toolbox” will include:
- 11 September 11:00 am – 12:00 pm Laura Harrington will talk about the erstablishment of the Northeast Regional Center for Excellence in Vector Borne Diseases.
- 13 September 11:00 am – 12:00 pm Scott Isard will talk about iPIPE or the integrated Pest Information Platform for Extension and Education.
- 25 September 11:00 – 12:00 A Team of people, including Rick Cooper and George Hamilton, will discuss the Brown Maromorated Stink Bug and control.

From the abstract: The lone star tick, Amblyomma americanum, is a vector of Ehrlichia chaffeensis and E. ewingii, causal agents of human ehrlichiosis, and has demonstrated marked geographic expansion in recent years. A. americanum ticks often outnumber the vector of Lyme disease, Ixodes scapularis, where both ticks are sympatric, yet cases of Lyme disease far exceed ehrlichiosis cases. We quantified the risk for ehrlichiosis relative to Lyme disease by using relative tick encounter frequencies and infection rates for these 2 species in Monmouth County, New Jersey, USA. Our calculations predict >1 ehrlichiosis case for every 2 Lyme disease cases, >2 orders of magnitude higher than current case rates (e.g., 2 ehrlichiosis versus 439 Lyme disease cases in 2014). This result implies ehrlichiosis is grossly underreported (or misreported) or that many infections are asymptomatic. We recommend expansion of tickborne disease education in the Northeast United States to include human health risks posed by A. americanum ticks.

From the Abstract: We describe a 2-yr trial to evaluate the ability of SELECT Tick Control System (TCS) host-targeted bait boxes to reduce numbers of host-seeking Ixodes scapularis nymphs in a residential neighborhood. After four successive 9-wk deployments, nymphal and larval I. scapularis infestation prevalence and intensity were significantly reduced on target small mammals. In addition, these deployments resulted in 87.9% and 97.3% control of hostseeking nymphs in treatment sites at 1 yr and 2 yr postintervention, respectively. Installation of a protective metal cover around the SELECT TCS bait boxes eliminated nontarget wildlife damage to bait boxes that resulted in failure of previous bait box types. The results are discussed in the context of the residential environment and future research needs.

Dr. Fonseca will attend a Strategic meeting of the Worldwide Insecticide resistance Network (WIN) that will be held in Rio de Janeiro, BRAZIL, from May 04-05, 2017. This meeting is supported by the WHO Research & Training program on Tropical Diseases (TDR) and the Department of Neglected Tropical Diseases (NTDs) and the US-Centers for Disease Control and Prevention (US-CDC).
A proposal entitled “Predicting the evolution of vector-borne disease dynamics in a changing world” by Dr. Fonseca was top rated in the NSF DEB Ecology of Infectious Diseases panel (five “excellent” and one “very-good”) and recommended for funding. Using Next-Generation genomics we will generate one of the first comprehensive datasets detailing the evolutionary potential of the major players in a complex multi-host disease system: avian malaria in endemic Hawaiian birds transmitted by invasive mosquitoes. Our results will help mitigate the anthropogenic impacts associated with invasive species and climate change, and can be translated directly into practical management recommendations. This 4 year $2,498,876 project is slated to start on July 2017.
A grant on”Climate Change, Nuisance Mosquito Populations, and Long-term Resilience of Coastal Salt Marsh Systems” was awarded to the Center for Remote Sensing & Spatial Analysis (CRSSA), the Center for Vector Biology (CVB) and the Jacques Cousteau National Estuarine Research Reserve (JCNERR) plus in collaboration with state and county mosquito agencies.
This container mosquito and vector of many arboviruses, including Zika, is not easy to control given it’s often cryptic habits. The diagram above illustrates the many strategies that could be employed to minimize the impact of this and other container species. Read more of Ary Faraji and Isik Unlu’s paper in the Journal of Medical Entomology describing the pros and cons of the various control techniques for this invasive species.
Karl Maramorosch passed away on May 9 in Poland while visiting friends. An eminent virologist, entomologist and plant pathologist, Karl was a wealth of information, always willing to talk and often in many languages. His kindness and dedication were unparalleled. He was often the first to arrive in the Entomology Department despite being well into “retirement.” This unique scholar will be sorely missed and our condolences to his friends and family.
