Article Synopsis
  • * New Jersey mosquito control agencies have been using wooden resting boxes for surveillance since 1975 and conducted studies to evaluate mosquito traps, aiming to optimize the collection of the main EEEV vector, Culiseta melanura.
  • * The studies found that corrugated plastic boxes were better at trapping blood-fed Cs. melanura than other types of traps, and non-CO2 baited traps were more effective than dry ice traps for capturing host-seeking mosquitoes, highlighting the need for agencies to reassess their EEE

The control of medically important container-inhabiting mosquitoes is an ongoing challenge for mosquito control operations. Truck-mounted application equipment is a common option for rapid areawide larvicide deployment utilized by mosquito control operations. We tested the effectiveness of two truck-mounted sprayers (A1 Super Duty + Buffalo Turbine CSM3), for the deployment of water-dispersible biopesticides (VectoBac WDG:VectoLex WDG 50:50).

We developed an index for use by New Jersey counties to measure West Nile virus (WNV) transmission risk to the human population. We used a latent profile analysis to develop the index, identifying categories of environmental conditions associated with WNV transmission risk to humans. The final model included 4 indicators of transmission risk: mosquito abundance and minimum field infection rate, temperature, and human case count.

Pesticide resistance in arthropod vectors of disease agents is a growing issue globally. Despite the importance of resistance monitoring to inform mosquito control programs, no regional monitoring programs exist in the United States. The Northeastern Regional Center for Excellence in Vector-Borne Diseases (NEVBD) is a consortium of researchers and public health practitioners with a primary goal of supporting regional vector control activities.

Adult control of Aedes albopictus via ultra-low volume is difficult because this species occurs primarily in peridomestic habitats where obstacles such as buildings and vegetation can disrupt spray plumes and droplet dispersion. We determined droplet penetration and characterization of a pyrethroid adulticide applied from the ground at mid (46.77 ml/ha) and maximum (93.

A checklist of 63 species of mosquitoes endemic in New Jersey is presented. Although Aedes albopictus was included in the previous checklist, the species has dramatically increased its geographic range and population numbers in recent years, and it is now prevalent in 19 of New Jersey's 21 counties. The invasive Aedes japonicus japonicus is also now widespread throughout the state and is an addition to the previous checklist.

Duet was field evaluated against caged Aedes albopictus, with the use of a truck-mounted ultra-low volume (ULV) cold aerosol sprayer at the rate of 90.6 ml/ha. Cages were placed in 3 rows stationed 30.

A supporting stand to suspend rotating impactors and mosquito cages is a requirement for field tests during pesticide efficacy trials. We present schematics for a collection device and associated support system for sampling droplets of ultra-low-volume (ULV) sprays during mosquito adulticide applications. This system offers the advantages of cost efficiency, increased ease of deployment, off-season storage, visibility, stability, and ULV collection efficacy.

From a discarded heavy-equipment tire (ca. 57 liter) at an industrial construction site, we collected 655 (86.0%) Orthopodomyia signifera, 23 (3.
