Bacillus thuringiensis serotype israelensis (Bti) is a group of bacteria used as biological control agents for larvae stages of certain dipterans. Bti produces toxins which are effective in killing various species of mosquitoes, fungus gnats, and blackflies, while having almost no effect on other organisms.

2024年6月3日 · Bti is a biological or a naturally occurring bacterium found in soils. (Bti is short for Bacillus thuringiensis subspecies israelensis.) It contains spores that produce toxins that specifically target and only affect the larvae of the mosquito, blackfly and fungus gnat.

Bacillus thuringiensis subsp. israelensis (Bti) is a naturally occurring soil bacteria used as a microbial insecticide to control the spread of vector-borne diseases, protect public health, and manage insect pest species.

A bio-rational control, Bacillus thuringiensis israelensis (Bti) is present naturally and controls the larval stage of certain Dipterans – mosquitoes, fungus gnats, and black fly. It has been used as a natural control measure since the 1960's by backyard gardeners and commercial growers alike since it is target specific and safe for use ...

苏云金杆菌 (Bacillus thuringiensis，简称Bt)是目前产量最大、使用最广的生物杀虫剂。 它的主要活性成分是一种或数种杀虫晶体蛋白 (insecticidal crystal proteins，ICPs)，又称δ-内毒素，对鳞翅目、鞘翅目、双翅目、膜翅目、同翅目等昆虫，以及动植物线虫、蜱螨等节肢动物都有特异性的毒杀活性，而对非目标生物安全因此，Bt杀虫剂具有专一、高效和对人畜安全等优点目前苏云金杆菌商品制剂已达100多种，是世界上应用最为广泛、用量最大、效果最好的微生物杀虫剂，因而 …

Bacillus thuringiensis israelensis was registered for use in 1981 (Tanada and Kaya, 1993) and was rapidly developed in the 1990s into products used for mosquito control in many countries. Bacillus thuringiensis israelensis became important in attempts in the 1980s and 1990s to control black flies, which serve as a vector for the nematode that ...

Bacillus thuringiensis subsp. israelensis (Bti) is the first subspecies of B. thuringiensis (Bt) found to be toxic to dipteran larvae. This gram-positive spore-forming subspecies is the most powerful and environmental-friendly biological alternative component in integrated programs to control disease vectors [ 8 , 9 ].

Chemical Action and Usages: Bacillus thuringiensis is a naturally occurring soil bacterium disease that is fatal to the larva stage of certain insects. There are a number of strains of Bt, but the most commonly used are the kurstaki strain (Bt k) and the israelensis strain (Bt i). Each strain is specific to the insect larvae it controls.

Since the discovery of Bacillus thuringiensis (Berliner) serovariety israelensis de Barjac (Bti) and efficacious isolates of Bacillus sphaericus Neide, formulations of these bacteria have become the predominant non-chemical means employed for control …

自1977年L.J.Goldberg博土分离出苏云金杆菌以色列变种(Bacillus thuringiensis Var.israelensis(以下简称B.t.i)后,相继发现它对许多种蚊幼虫具有很高的杀虫活性。 1979年我国先后从国外引进该菌株后,各地开展了对B.t.i的生物学特性、杀虫机机制及应用方面的研究,本文特综述 ...
