DEP AND NEW JERSEY DEPARTMENT OF AGRICULTURE PARTNER IN
BATTLE AGAINST MOSQUITOES
Copepods latest tool used to fight mosquitoes
(12/P72) TRENTON - With conditions ripe for mosquito breeding in standing water around New Jersey, the Departments of Agriculture and Environmental Protection are once again teaming up to release a tiny, shrimp-like crustacean with a hearty appetite for mosquito larvae.
Macrocyclops albidus, commonly known as copepods, is being bred in large numbers at the Department of Agriculture’s Philip Alampi Beneficial Insect Rearing Laboratory in West Trenton, and is one tool used by the DEP’s Mosquito Control Program to fight disease-spreading mosquitoes. New Jersey Secretary of Agriculture Douglas Fisher and Bob Kent, administrator of DEP’s Office of Mosquito Control Coordination, visited Cape May County on Friday for the latest release of the copepods.
“This is one of a variety of tools employed by DEP and the Department of Agriculture to help towns and counties across the state battle mosquito infestation,’’ said DEP Commissioner Bob Martin. “The partnership between state agencies and county government is paramount to successfully dealing with these infestations."
“This is the second season the copepod program is in full swing, demonstrating the successful partnership between NJDA, DEP and the counties against a common enemy – the mosquito,” said Secretary Fisher. “This effort is important to agriculture because mosquito-borne diseases such as Eastern Equine Encephalitis and West Nile Virus can be deadly to horses.”
New Jersey has already had one probable case of Eastern Equine Encephalitis (EEE) this season – a 3-year-old horse from Burlington County was euthanized in May after contracting the disease. Last year, the one and only case of EEE occurred in October.
Kent said it has been an early and nasty mosquito season so far. Intermittent rain followed by drying and then more rainfall has led to the creation of many micro habitats for mosquitoes, such as wheelbarrows, gutters, boat tarps and flower pots, which presents a statewide problem.
The copepods thrive in fresh water and are a valuable tool in battling mosquitoes in artificial containers, roadside ditches, small water pools, clogged downspouts and other, smaller wet areas that can breed plenty of mosquitoes. They are especially helpful tools in fighting mosquitoes near schools, where use of certain pesticides are restricted.
Copepods have been released so far this spring and summer at locations in Bergen, Cape May, Morris and Passaic counties, with a release expected soon in Ocean County. Other expected participants include Atlantic, Cumberland, Hunterdon, Middlesex, Monmouth and Warren counties.
DEP’s pesticide-free mosquito fighting program also employs the use of several small fish with an appetite for mosquito larvae. Gambusia affinis, or mosquitofish, and fathead minnows, freshwater killfish and bluegill sunfish have been stocked in many lakes and ponds statewide.
"The use of these biological control agents is but one small part of our statewide integrated approach to mosquito control, and not a replacement for long-established procedures,” said Kent.
“The state's assistance to county mosquito control programs helps to reduce their dependence on insecticides, providing them a variety of natural tools to help deal with mosquito issues.’’
The Cape May County Department of Mosquito Control has been in existence since 1915. It manages mosquito populations using an integrated control approach, stressing environmental safety, economics, efficacy, research and surveillance in order to protect the health and welfare of county residents and the many tourists who visit during the months mosquitoes are active. Cape May is one of 11 counties this year participating in the copepod program.
