VEERALIN®LN

VEERALIN®LN is made of high density polyethylene (HDPE) incorporated with Alpha-cypermethrin and piperonyl butoxide.

  • With improved bio-efficacy
  • Gives better personal protection against malaria vectors even after successive washing up to 20 washes.
  • Protects against pyrethroid resistant. An gambiae bites is very high: 71-88%
  • 95% knock down (until 20 washes) recorded against kdr resistant strain in cone bio-assay
  • Uses real controlled release technology
  • Sustained bio-efficacy due to high retention of both the insecticide and the synergist

KEY FEATURES

DURABLE

VEERALIN®LN has unsurpassed protection at the seams by using five thread over locking stitch with dual seams, providing double protection.

LONG LASTING

No fear of losing the insecticide on washing because VEERALIN®LN uses true controlled release of insecticide incorporated into the HDPE monofilaments.I am text block. Click edit button to change this text.

BETTER BIOEFFICACY

The insecticide (alpha-cypermethrin) used in VEERALIN®LN is a broad spectrum insecticide and is very effective against most common species of mosquitoes.

ASSURED QUALITY

In-house testing facilities for both physical and chemical properties, and strict quality management in each and every stage of manufacturing.

GREEN PRODUCT

VEERALIN®LN is packed in oxoblodegradable plastic bags. The net (HDPE) can also be recycled.

READY TO USE

No chemical treatment is required. WHOPES full recommendation March 2016. WHO pre-qualification for Vector Control Products January 2018.

Very high retention of alpha-cypermethrin secticide and synergist after 20 washes.

Improved bio-efficacy against pyrethroid-resistance malaria vector.

ADVANTAGES OF POLYETHYLENE

a) Withstands harsh washings (typical washing style in villages). Only the a.i. concentrations on the surface of the yarn is depleted no matter how harsh the washing is. Major portion of a.i. is impregnated into the fibre. Therefore lesser loss of a.i. leading to more efficient long term protection. Less dumping of hazardous material into environment.
b) Made of 150 denier High density polyethylene monofilament yarn. Heavy duty and very strong. High bursting strength of upto 550kpa for seams
c) High performance and durability. Gives very long life up to 5 years.
d) Extra Safe. Safer for child use a major portion of the a.i. is not on the surface of the yarn but incorporated inside the fiber.
e) Long term cost benefits. Provides up to 5 years of useful life.
f) Ultra fast quick regeneration under normal tropical climate. Only 24 hrs to regain full efficacy after each washing. Does not require any special heat treatment to boost up regeneration.
g) Greener product as MAGNeT®LN uses lesser heat energy during the manufacturing process thus leaving a lower carbon foot print.
h) It is possible to incorporate PBO synergist into Polyethylene monofilament to increase the bioefficacy of the LLIN. VKA Polymers has developed VEERALIN®LN which is a PBO incorporated LLIN with Alphacypermethethrin as active substance. VEERALIN®LN has already attained its WHOPES recommendation.

HOW DOES VEERALIN®LN WORK?

Mosquitoes develop resistance to insecticides over a period of time. Mosquitoes have the ability to enzymatically degrade (metabolize) the insecticides using enzymes secreted in their body. On continuous usage of the same insecticide for a long period the mosquitoes start over-expressing the enzymes that are responsible for detoxification of insecticides. Hence, the insecticide such as a pyrethroid will become ineffective in knocking down the mosquitoes and the resistance thus developed is known as metabolic resistance and also referred to as knockdown resistance (kdr).

To overcome this, if Piperonyl butoxide(PBO) that is capable of binding to the metabolic enzymes is used along with a pyrethroid insecticide, then PBO attaches itself to the degrading enzyme in mosquitoes and inhibits the detoxification of pyrethroid (insecticide). As degradation of pyrethroid in mosquito's body in inhibited, the biological activity of the pyrethroid insecticide is sustained over a longer period. Thus, the PBO in VEERALIN®LN increases the bio-efficacy of pyrethroid insecticide. This acts as a synergist by binding itself to the detoxifying enzymes. It may be noted that the synergist PBO by itself is not an insecticide and does not posses any insecticidal activity (knockdown or mortality), but enhances the activity of pyrethroid insecticides.

The lethal combination of Alpha cypermethrin and PBO incorporated into VEERALIN®LN filaments knocks down and kills pyrethroid resistant mosquitoes sitting on it. Apart from providing strong physical barrier due to high density polyethylene monofilament, VEERALIN®LN gives a far better chemical protection to people sleeping under it and is 100% safe.

CONTROLLED RELEASE TECHNOLOGY

VEERALIN®LN – A POLYETHYLENE LN CONTAINING ALPHA – CYPERMETHRIN AND PBO

  • Reservoir of insecticide in the fiber core
  • True controlled release of insecticide molecules from fiber core to its surface
  • Insecticide lost from surface on washing is replenished from the reservoir within
  • After 20 washes: Bioefficacy is 90-95% of new VEERALIN®LN

Sustained bioefficacy and high denier HDPE make VEERALIN®LN really long lasting (up to 5 years)
