INTRODUCTION

Bacillus thuringiensis, abbreviated Bt, is a type of Bacillus cereus that includes many varieties. The bacteria can produce two major toxins, namely endotoxin (parasitic crystals) and exotoxins, causing the pests to stop feeding, and finally pests die of hunger and poisoning. Therefore, the bacillus can be used as a low-toxicity microbial insecticide for controlling orthoptera, coleoptera, diptera, hymenoptera, especially lepidopteran pests.


THE PRINCIPLE OF PEST CONTROL

Bacillus thuringiensis (Bt) is a species of Bacillus cereus that contains many variants. It can be used as a low-toxicity pesticide source for microorganisms, mainly stomach poisoning.

1. The bacteria can produce two major toxins, namely endotoxin (parasporal crystals) and exotoxins, which stop the pests from feeding. The last pests are starved and die, and the exotoxins are slowly acting. They play a significant role in molting and metamorphosis.
The period is the peak of RNA synthesis and exotoxins can inhibit DNA-dependent RNA polymerases. The drug is slow, the pests can take effect about 2 days after feeding, and the effective period is about 1 day.

2. Therefore, they should be used 2 to 3 days ahead of conventional chemical agents, and they should be used more effectively at low pests. It is safe for fish and bees, but it is highly toxic to silkworms.

3. Its main active ingredient is one or more insecticidal crystal proteins (ICPs), also known as δ-endotoxins, from Lepidoptera, Coleoptera, Diptera, Hymenoptera, Homoptera, etc. Insects, as well as animal and plant nematodes, crickets and other arthropods have specific poisoning activity, and non-targeted biological safety. Therefore, Bt insecticides have the advantages of specificity, high efficiency and safety to humans and animals.

4. Currently, Bacillus thuringiensis commercial preparations have been With more than 100 species, it is the most widely used, most used, and best-performing microbial insecticide in the world, and has received much attention.

5. However, commercial Bt preparations also show some limitations in production control, such as poor availability, insensitivity to older larvae, short field persistence, and unstable genetic traits of recombinant engineered strains, which have become impacts on the successful use of Bt. Constraints.

6. Therefore, in order to increase the insecticidal effect of Bt preparations, the study of its synergistic pathways has become a worldwide research hotspot, mainly including: screening for potentiating strains; using chemical additives, phytosarasin, and chitinase as synergies. Substances; interactions between entomopathogenic microorganisms, etc.

It is used to control Lepidoptera pests such as Pieris rapae, Plutella xylostella, Spodoptera litura, Spodoptera litura, Brassica napus, Plutella xylostella, Corn Borer, Cnaphalocrocis medinalis, Spodoptera, pine caterpillar, tea caterpillar, tea Aphids, corn tapeworms, cardamom, silver-winged moth and other pests.

Some subspecies or strains also have preventive and control effects on vegetable root-knot nematodes, mosquito larvae, cockroaches and other pests.



MAIN ADVANTAGES OF BT PESTICIDES

1. Biological pesticides do not pollute the ecological environment;
2. It has specific toxicity to target pests and is non-toxic to non-target pests and natural enemies such as silkworm;
3. The control effect is good, and the control range is wide. It can be widely used in the prevention and control of pests in agriculture, forestry, fruits, vegetables, and urban garden plants, and pests are not susceptible to resistance;
4, easy to use, will not cause user poisoning when used;
5, the production process is simple, the main production of raw materials for agricultural and sideline products, production and use of low cost.
