Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of pesticide combination containing Dipel and Celastrus angulatus
Object.
Background technology
Dipel (Bacillus thuringiensis, abbreviation Bt) is a kind of production crystal including many mutation
Bacillus can be cooked microbial source low toxic pesticide, based on stomach poison function.The bacterium can generate two major classes toxin, i.e. endotoxin
(parasporal crystal) and exotoxin make pest stop feeding, and last pest is because hungry and dead, and exotoxin effect is slow, is sloughing off
Effect is apparent when skin and metamorphosis, the two periods are the peak periods of RNA synthesis, and exotoxin can inhibit the RNA polymerizations dependent on DNA
Enzyme.Medicine effect is slow, can just take effect within 2 days or so after pests, about 1 day lasting period, therefore should compare conventional chemical when use
Medicament shifts to an earlier date 2~3 days, and preferable in pest low age phase using effect.Therefore the bacillus can be cooked microbial source low toxic pesticide, be used
In prevention Orthoptera, the various pests of coleoptera, Diptera, Hymenoptera, especially Lepidoptera.
The active insecticidal components of Celastrus angulatus have anesthesia, food refusal and stomach toxicity, action of contace poison to pest, and do not generate anti-medicine
Property does not kill the features such as natural enemy, stable in physicochemical property, especially to having stomach to insects such as black cutworn, lopper worm, anomis flavas
Malicious toxic action.According to recent studies have shown that, Celastrus angulatus to beet armyworm, prodenia litura special efficacy, to rice leaf roller, pink rice borer,
Striped rice borer, yellow rice borer are efficient, and the lasting period is up to 30 days, because being botanical pesticide, pest not will produce resistance.
Lepidoptera pest distribution is extremely wide, the abundantest with tropical type.The larva of most types is caused harm all kinds of
Cultivated plant, the often feeding of the bodily form the greater blade or brill moth limb to the greatest extent；Bodily form smaller often leaf roll, sew leaf, knot sheath, spinning netting
Or it pierces plant tissue feeding and causes harm.
It is the small green worm of diamondback moth alias, pointed at both ends, be the worldwide pest that migrates, wild cabbage of mainly causing harm, violet cabbage, broccoli,
The crucifers such as a kind of sedge dish, leaf mustard, cauliflower, Chinese cabbage, rape, radish.Harm characteristics：First instar larvae only feeding mesophyll, leaves
Epidermis forms spot transparent one by one in dish leaf, and dish leaf can be eaten into hole and incised by 3~4 instar larvaes, full leaf quilt when serious
It eats and reticulates.Often lobus cardiacus is concentrated to cause harm in seedling stage, influences packet.It is reserving seed for planting in strain, is endangering tender stem, young pod and seed.
Cabbage caterpillar larva bites host's blade, and when cabbage caterpillar feeding, fecal pollution is discharged in feeding.Larvae underwent 5 instars, 2
Mesophyll was only gnawed before age, is left layer of transparent epidermis, was mostly caused harm in blade back before 3 ages；Blade face is gone to after 3 ages to nibble, and nibbles blade
Hole is incised, and blade is all eaten up when serious, only remains thick vein and petiole, is caused to have no harvest, is easily caused soft rot of cabbage
Prevalence；The food ingestion of 4-5 instar larvaes accounts for the 97% of entire larval phase food ingestion.
Since people depend on the insecticide using single type, pest to easy to produce drug resistance, cause insecticide for a long time
Chemical dosage sharply increase, not only aggravated agriculture name financial burden, pollution environment.
Therefore, new efficient, less toxic, safe compounded pesticides prevention lepidoptera pest is developed to have great importance.
