Efficient Broad Spectrum Bt Biological Insecticides HaNPV For Cotton Pests

Efficient Broad-spectrum Biological Insecticides HaNPV + Bt Cotton Pests Pesticide​

Cotton is one of the most economically important crops in China, while insect pest damage is the major restriction factor for cotton production. The strategy of integrated pest management (IPM), in which biological control plays an important role, has been widely applied.

Trichogramma spp., Microplitis mediator, Amblyseius cucumeris, Bacillus thuringiensis and Helicoverpa armigera nuclear polyhedrosis virus (HaNPV) have been mass reared or commercially produced and used in China.

Baculoviruses comprising nuclear polyhedrosis virus (NPV) and granulosis virus (GV) have been successfully used as
insect pathogens because of their high virulence and specificity.

NPV and GV formulations are used for lepidopteran pests like Helicoverpa armigera (HaNPV) and Spodoptera litura (SlNPV) in India, besides Anticarsia gemmatalis NPV in Brazil, Lymanttria disper NPV, Orgyia pseudotsugata NPV in USA and GV of Pieris rapae in China.

Working Mechanism:
Helicoverpa armigera nucleo polyhedro virus (HaNPV) is a microorganism that kills cotton helicoverpa armigera. After spraying onto crops and being eaten by pests, the virus particles replicate and multiply in the pest body, and quickly spread to all parts of the pest. Parts of the body are drastically engulfed to consume the tissues of the worms, and the pests do not eat or move during the period of ‘illness’, causing a sub-lethal effect, and eventually the whole body is killed by water, spraying on the insects, the larvae that will hatch will bite after eating the egg shell Death by feeding on the virus. In addition, virus particles can continue to be transmitted to the next generation or other pests through the body fluids and feces of dead insects like a ‘plague’, so that field pests can be effectively controlled for a long time.

Main advantages of insect virus insecticides:
1. Strong pertinence, only effective to target pests, does not harm natural enemies and other non-target organisms, is conducive to maintaining ecological balance and preventing pests from rampant again.
2. Pests do not easily develop resistance. Insect viruses are essentially microorganisms with nucleic acid structures that can co-evolve with pests, which have difficulty developing resistance. So compared with chemical pesticides, insect virus insecticides have more market potential in pest resistance management.
3. No residue. The main components of insect virus insecticides are natural organisms, and there is no safety interval for the products, which can be harvested on the same day. For organic and green agricultural production bases with requirements of agricultural residues, insect virus insecticides are completely safe to use green pest prevention and control products.

1. Can be used for aircraft spraying, suitable for large area control of helicoverpa armigera.

2. Excellent effect to the oriental tobacco budworm on tobacco and chilli.

3. No safety interval period.

4. Pure biological preparation, harmless to fish, shrimp, humans and animals.

5. Strong selectivity, no damage to natural enemies, special effect on helicoverpa armigera.

6. Outstanding resistance to drug resistance and stubborn pests, no drug resistance after application.

7. Significant aftereffect. The virus can spread among generations of pests, and the drug effect lasts a long time.

Dosage: 3200~6400mL/Ha, spray

Insect virus insecticides with its strong specificity, the use of "poison to fight poison" new insecticidal concept, unique mechanism of action, good prevention and control effect, and has a significant advantage is the quality of agricultural products, agricultural ecological environment is very safe, is the future national focus of development.
