Bacillus Thuringiensis Israelensis

Bacillus thuringiensis israelensis for mosquito and fungus gnat control

Bacillus thuringiensis israelensis (BTI) is a biological larvicide, effectively targets the larvae of mosquitoes (Culiseta longiareolate), fungus gnats (Bradysia impatiens), and black flies (Simulium vittatum Zetterstedt). When applying it to aquatic habitats where these pests breed, it can control their populations while remaining safe for humans, pets, livestock, and beneficial insects. This microbial insecticide can be sprayed in a variety of locations, including man-made and natural ponds and lakes, wastewater treatment facilities, sewage lagoons, irrigation ditches, catch basins, rice fields, and any standing water containing mosquito larvae in crop fields. where to buy bacillus thuringiensis israelensis (bti) for mosquito controlNovobac supply both wettable powder and suspension liquid larvicide products for your option.

Target Species

  • Mosquitoes (Culiseta longiareolate)
  • Fungus gnats (Bradysia impatiens)
  • Black fly (Simulium vittatum Zetterstedt)

Bacillus Thuringiensis Israelensis target insect

How does bti kill mosquitoes

  • Bacillus thuringiensis israelensis (BTI) produces an insecticidal protein called the insecticidal crystal protein (ICP). When ingested by pest larvae, the ICP can paralyze their intestinal tract within minutes and cause the destruction of the intestinal lining, allowing the vegetative cells of the BTI to invade and cause sepsis.
  • This process leads to the death of the larvae from starvation and sepsis. The effects of biological larvicide are usually rapid, with some larvae dying within hours and complete larval mortality occurring within 24 hours. However, this mosquito killer product is only effective against pest larvae and will not affect pupae or adult mosquito. Late larval stages that are no longer actively feeding are also not affected by this bacteria.

 

Benefit

  • Effective and fast-acting biolarvicide against mosquito larvae
  • killing them within 2-24 hours.
  • Highly specific in its activity against mosquitoes and does not harm non-target organisms
  • Easy to mix in water and can be sprayed through various equipment types.
  • Its effectiveness can be quickly assessed in the field.

How to use bti for mosquitoes

  • Bti mosquito larvicide can be applied to standing water using water dispersible granules or liquid formulations, diluted and sprayed by hand or with a spreader in smaller areas, or by using ground or aerial dispersal methods for larger areas.
  • Apply at a rate of 1 gram per square meter in the early stages of mosquito population development, with higher populations requiring double the dosage.
  • Reapplied after 8-12 days to extend its effectiveness for mosquito treatment
  • For optimal control of Lepidoptera pests, it is best to apply the product to pest eggs before the incubation period.
  • To ensure the best control effect, it is recommended to spray mosquito killer in the morning or on a cloudy day, and to reapply it if it rains within 6 hours after application.

 

Notes

  • Bacillus thuringiensis var israelensis does not persist in water or soil and is naturally present in soil. Its active ingredient and the protein crystals it produces will settle on the bottom of water bodies and break down organically or become food for other organisms.
  • BTI mosquito killer does not show cross resistance to chemical insecticides and can be applied in areas where resistance to organophosphates or pyrethroids has been observed.
  • It is not poisonous to beneficial insects such as ladybugs, dragonflies, honeybees, and various types of flies, and does not harm aquatic creatures like Crustacea, oysters, shrimp, crabs, mollusks, flatworms, and Amphibia.
  • BTI-based biological larvicide have been used in major mosquito and fungus gnats control programs for over 20 years without any reported harmful side effects.
