History and 100-Year Anniversary Celebration of Delta Mosquito and Vector Control District – Come and Join Us!

By Erick Arriaga and Mustapha Debboun

Delta Mosquito Abatement District (DMAD) was formed on September 19, 1922 including Visalia and the immediate suburban area (Figure 1). The Visalia Women’s Civic Club was highly influential in its formation. The interest was stimulated by numerous cases of the mosquito-borne disease, Malaria as well as a severe pest mosquito problem. The Delta MAD included 16 square miles at that time and was the seventh mosquito abatement district to be formed in California when the California State Legislature incorporated the formation of mosquito abatement districts in 1915. The Delta MAD began with one full-time employee, Director E.I. Feemster and two seasonal employees during each summer to cover the original 16 square miles that made up the District during the first 20 years. After the end of the second World War II, and from 1946 to 1948, Delta MAD annexed the northern part of Tulare County to include the following cities, i.e., Goshen, Traver, Dinuba, Orosi, Ivanhoe, Woodlake, Exeter, Lemon Cove, and Farmersville, bringing the size of the District to over 712 square miles. The growth of the Delta MAD was due to increased public interest and demand on incorporating mosquito control in their new communities. Throughout the years, Delta Mosquito and Vector Control District (DMVCD) as it is known now, has taken on several additional responsibilities and integrated mosquito management methods of control (Figure 2). Originally, the main mission to control mosquitoes was to control the spread of their mosquito-borne disease, Malaria. However, in the 1940s and 1950s, Delta MAD began conducting missions to control also filth flies using physical, mechanical, and source reduction, as there was a large issue with flies among the local fruit growers within the District. In 1960, Delta MAD purchased its first plane to apply treatments on larger breeding sources (Figure 3). As efforts on source reduction were showing success, the amount and size of sources were reduced, and aerial treatment was contracted out to aerial-application piloting services for the few areas where aerial pesticide application was still needed. In the 1970s, Delta MAD intensified its work to control the spread of the mosquito-borne disease, Western Equine Encephalitis. After 51 years of being known as Delta Mosquito Abatement District, its name was changed to Delta Vector Control District in 1973. In 2021, the District’s name was changed to Delta Mosquito and Vector Control District with an updated logo to reflect its priorities. In 2022, Delta MVCD began a collaborative effort with Oxitec Ltd on a new and innovative mosquito control method approved by the Environmental Protection Agency to control the invasive yellow fever mosquito, Aedes aegypti. Today, Delta Mosquito and Vector Control District serves over 712 square miles in Northern Tulare County and employs a team of 18 full time employees who are supplemented by an additional 25 seasonal employees during the peak summer months of the mosquito season. Every season, our team at Delta MVCD works diligently on incorporating better, improved, innovative, and more efficient ways of combatting the mosquitoes that transmit serious mosquito-borne diseases. This year, we are celebrating the 100-year Anniversary Milestone. We invite everyone to join us on Saturday, October 8, 2022 for an Open House in celebrating the District’s 100th Anniversary (Figure 4). All are welcome to attend this monumental milestone to explore the District’s headquarters, laboratory, fish hatchery, new pesticide application equipment, and enjoy food, music, and giveaways. The event will be held at our District headquarters location, i.e., 1737 W. Houston Ave., Visalia, California.
