Description
Technical field
The invention belongs to insect growth regulator, IGR in the application in foodstuff preservation field, belong to a kind of organic-biological control agent.
Background technology
Insect growth regulator, IGR (insect growth regulator) is the normal growth and development that insect is upset using medicine,
Make the individual viability decline of insect, dead or population extinction, so as to reach pest control, the purpose of cover crop.Such medicine
Thing has low toxicity, low stain due to its unique mechanism of action and to people and animals and the characteristic of beneficial insect safety.Exploitation is such
Medicine is conducive to the sustainable development of agricultural chemicals.From the point of view of current pesticide market and development trend, some organophosphorus pesticide (such as first
Amine phosphorus) progressively it is disabled, limit the use of, and pyrethrin pesticide, due to its resistance problem, its market share is also declining year by year.Take
And instead of be antibiotic and insect growth regulator, IGR sudden emergence.Therefore, a kind of new biocontrol agent is developed to apply
In terms of foodstuff preservation, have great importance.
The insecticide mechanism that the country is largely used at present is poisoning property, such as organophosphorus pesticide, pyrethroid, carbamic acid
Esters, wherein most kinds are adapted to by insect due to being used for a long time, particularly those breed fast insect, have produced
Raw resistance (nerve poisoning can be resisted), but the interference of juvenile hormone class is not suitable with.And fenoxycarb is at present at home not yet
Use, add the insecticidal mechanism of uniqueness, resistance, thus the evil developed immunity to drugs to conventional pesticide is not present in most insects
Worm, it will show the high desinsection advantage of activity.
Corpus allatum hormone analog fenoxycarb has that toxicity is low, insecticidal activity is high, formulation rate is small, is easily dropped in soil and water
Solution, it is free from environmental pollution, to natural enemies security, do not destroy the advantages such as the ecological balance.Both at home and abroad to benzene oxygen in many agricultural chemicals information publications
Prestige thinks very highly, and is considered the new varieties that should develop at present；Widespread adoption, especially on fruit tree and cotton, is prevented and treated
Effect is good.With the reinforcement of the progress of application technology, and environmental consciousness, fenoxycarb consumption and scope will constantly increase.
After it is found that two aromatic hydrazide kind compounds can cause, tested insect is precocious, lethal is casted off a skin so that past people are uncommon
The hope that insect receptor (EcR) is developed to the insecticide with commercial significance as target is hoped, becomes real possible.
In two subsequent ten years, scientists have carried out substantial amounts of work in this field, are widely used in the comprehensive of insect
Close preventing and treating, although the insecticidal activity and insecticidal spectrum of two aromatic hydrazide kind insect growth regulator, IGRs of different structure are not quite similar, but by
In poisoning symptom and its mechanism of action caused by these compounds be very similar.
Above-mentioned insect growth regulator, IGR is belonging respectively to following 2 types according to the mode of action to insect：1. ABG-6215, insect protects
Young hormone analogs, it influence insect cast off a skin and larva metamorphosis；Corpus allatum hormone be secreted by insect corporal allata, energy
Larva is set to keep a kind of compound of young age state.The approximate natural insects hormone of artificial synthesized thousands of kinds of chemical constitutions now
Compound, and referred to as insect hormone analog, the insecticidal activity with wide spectrum, to Diptera, coleoptera, Homoptera, film
Wing mesh, Lepidoptera, different sub- wing mesh, Thysanoptera, 50 various pests of Corrodentia and some acarians, nematode are effective.2. diflubenzuron,
Chitin synthesis inhibitory preparation, it can restrain the formation of insect body surface chitin, and chitin synthesis inhibitor is a major class ureas
Compound, it can suppress the formation of insect chitin, and chitin is the main component of insect cuticle.The body wall of insect is very thin,
But it is made up of many layers, the endepidermis of wherein epidermis is thicker one layer, and its main component is exactly chitin.Chitin
Chemical property it is stable, water insoluble, alcohol and ether are also insoluble in weak acid and highly basic, this is also that insect can after death protect for a long time
The reason for depositing without rotting.Work as insect, particularly larva, new epidermis, chitin synthesis inhibitor are formed when casting off a skin
Formation with regard to larva chitin can be suppressed, this just prevent larva because new epidermis from：Deformity is caused, it is final dead.Chitin
Matter synthetic inhibitor prevents and treats grain storage pest, and its mechanism is that this.Although corpus allatum hormone, which covers 515, can efficiently control storage
Grain insect, and used as grain protecting agent.But this kind of compound has following defect, the i.e. control for low instar larvae to imitate
It is really poor, while the generation of disguised grain storage pest (rice weevil and sitophilus zea-mais etc.) first filial generation can not be controlled.And chitin synthesis presses down
Preparation, can not only efficiently control rice weevil and sitophilus zea-mais etc. moth corrosion insect, but also with it is low to mammalian toxicity and
In natural environment the advantages of rapid decomposition.
