Pesticides Used

Adult Mosquito Control Pesticides

We use Anvil 10/10 (active ingredient is Sumithrin (p-Phenothrin)) for our truck-mounted ULV adulticiding.

Sumithrin (d-Phenothrin)

NOTE: EPA toxicity levels are grouped into four categories: (IV) relatively non-toxic, (III) slightly toxic, (II) moderately toxic, and (I) highly toxic. Sumithrin is rated as slightly toxic (III). By comparison, caffeine would be labeled moderately toxic (II).

FACTS ABOUT SUMITHRIN

Sumithrin is a synthetic pyrethroid
Pyrethroids are synthetic compounds related to the naturally occurring Chrysanthemum sp compound pyrethrum
pyrethroids affect the nervous system by causing sodium channels to remain open longer causing repetitive firing of nerves ("jitters")
Symptoms of acute poisoning by pyrethroids include restlessness, incoordination, and hyperactivity, followed by prostration and paralysis
Toxicity to people: LOW RISK

·  found to be a non-irritant to skin & eyes
·  not found to be a skin sensitizer (allergen)
·  not found to be oncogenic (tumor-producing)
·  not found to cause birth defects
·  rapidly metabolized (broken down by the body)
·  metabolic products are non-toxic

Toxicity to non-targets:
other mammals - low risk
birds - low risk
fish - high risk

However, (1) sumithrin is unstable and insoluble in water, (2) breakdown products have low to no toxicity, and (3) no fish kills have been attributed to proper use of sumithrin.

bees - high risk

However, (1) sumithrin is applied after dusk when bees are notactive, (2) sumithrin is applied at very low rates, and (3) sumithrinbreaks down rapidly in sunlight.

other invertebrates - unknown but probably high, especially night-flying insects. Sumithrin is a very good insecticide.

However, it can be rapidly biodegraded (broken down by living systems).

Environmental Risk

1. sumithrin breaks down rapidly in sunlight

2. sumithrin is unstable and insoluble in water - risk to groundwater is low

3. sumithrin is non-volatile (doesn't release vapors)

4. sumithrin breakdown products have low to no toxicity
Therefore: ENVIRONMENTAL RISK IS LOW

Efficiency as a Pesticide
1. sumithrin is applied when mosquitoes are flying
2. sumithrin produces rapid knockdown and mortality in mosquitoes at application rates of .0024 lbs. of
sumithrin per acre The product used Anvil 10+10 is comprised of 10% sumithrin, 10% is the synergist piperonyl butoxide and 80% is comprised of inert ingredients
3. sumithrin is not persistent in the environment, so the
chance of resistance developing is low



Larval Mosquito Control Pesticides

Vectolex WSP

Altosid WSP

VectoBac 12AS

Bti

NOTE: EPA toxicity levels are grouped into four categories: (IV) relatively non-toxic, (III) slightly toxic, (II) moderately toxic, and (I) highly toxic. Bti is rated as relatively non-toxic (IV). By comparison, caffeine would be labeled moderately toxic (II).

FACTS ABOUT BTI

Bti is a microbial insecticide
Bacillus thuringiensis israelensis is a rod-shaped bacterium which releases a toxin crystal when it reproduces
This crystal is only toxic to mosquitoes, black fly, and a few related species
Bti is considered relatively non-toxic to humans and other mammals

Toxicity
to people: LOW RISK

found to be a non-irritant to skin & eyes

not found to be oncogenic (tumor-producing)

not found to cause birth defects

Toxicity to non-targets:

other mammals - essentially no risk

birds - essentially no risk

fish - essentially no risk

bees - essentially no risk

other invertebrates - low to none for most other invertebrates, including other insects. However, Bti has been found to affect dixids, chironomids, and ceratopogonids.

Environmental Risk
1. Bti is highly specific for mosquito and black fly larvae
2. Bti is applied directly to mosquito-producing habitats
3. Bti produces no toxic residues - risk to groundwater is low
4. Bti is non-volatile (doesn't release vapors)
5. Bti is harmless to beneficial aquatic organisms, including
insect predators
Therefore: ENVIRONMENTAL RISK IS VERY LOW

Efficiency as a Pesticide

1. Bti is applied to larval habitat to kill mosquitoes before
they become pests
2. Bti produces rapid knock-down and mortality in
mosquitoes, usually within 24 hours after application                                                                                                                                    3. Bti is not persistent in the environment, so the chance of resistance developing is low



Altosid

NOTE: EPA toxicity levels are grouped into four categories: (IV) relatively non-toxic, (III) slightly toxic, (II) moderately toxic, and (I) highly toxic. Altosid is rated as relatively non-toxic (IV). By comparison, caffeine would be labeled moderately toxic (II).

FACTS ABOUT ALTOSID


o Altosid is an insect growth regulator
o the active ingredient, Methoprene, is an insect juvenile hormone mimic
o Insect juvenile hormone affects the development of the insect to its adult stage (metamorphosis)
o Altosid is considered relatively non-toxic to humans and other mammals

Toxicity
to people: LOW RISK

found to be non-irritating to skin & eyes

found to be non-sensitizing to skin

not found to be oncogenic (tumor-producing)

not found to cause birth defects

Toxicity to non-targets:

other mammals - essentially no risk

birds - essentially no risk

amphibians - slight to moderate risk

fish - slight to moderate risk

bees - essentially no risk

other invertebrates - potentially high for other aquatic insects

and some aquatic invertebrates

Environmental Risk
1. Altosid is applied directly to mosquito-producing habitats
2. Altosid produces no toxic residues - risk to groundwater is
low
3. Altosid is non-volatile (doesn't release vapors)
Therefore: ENVIRONMENTAL RISK IS LOW

Efficiency as a Pesticide
1. Altosid is applied to larval habitat to kill mosquitoes
before they become pests
2. Altosid Briquets release effective doses of pesticide for
up to 30 days, providing long term control of mosquitoes
